Thymeleaf dynamic href using input value(s) - spring-mvc

I understand that Thymeleaf templates are rendered server-side, but is there a simple way to reference input values client side to create an href dynamically?
Here is what I currently have:
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>TEST</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<h1>Dynamic href</h1>
<p>name: <input type="text" name="name" /></p>
<p>age: <input type="text" name="age"/></p>
<p>color: <input type="text" name="color"/></p>
<a th:href="#{/userInfo(name='Americord',age='32',color='green')}">Submit</a>
</body>
</html>
Inside of my application controller I have:
#GetMapping(value = "/userInfo")
public String userInfo(#RequestParam(value = "name") String name,
#RequestParam(value = "age") String age,
#RequestParam(value = "color") String color) {
// get user related user information
return "success";
}
As you can see, right now the values for name, age & color are simply hard-coded. But I would like to reference the values from the input fields.
Maybe something like(?) :
<a th:href="#{/userInfo(name={name.value},age={age.value},color={color.value})}">
Submit
</a>

No, the only way to do this, is by using JS or jQuery. Thymeleaf once rendered, it simply can't modify anything else. Anyways, using jQuery is quite simple and you should make it work in no time. Something like the code below would do the trick.
var ageInput = $('#age');
var nameInput = $('#name');
var url = $('#dynamic-url');
ageInput.on('change', function() {
if($(this).val() !== "" && nameInput.val() !== "") {
url.attr('href', '/userinfo(age=' + $(this).val() + ', name=' + name.val() + ')');
} else if ($(this).val() !== "") {
url.attr('href', '/userinfo(age=' + $(this).val() + ')');
} else if (nameInput.val() !== "") {
url.attr('href', '/userinfo(name=' + nameInput.val() + ')');
}
});
nameInput.on('change', function() {
if($(this).val() !== "" && ageInput.val() !== "") {
url.attr('href', '/userinfo(age=' + ageInput.val() + ', name=' + $(this).val() + ')');
} else if ($(this).val() !== "") {
url.attr('href', '/userinfo(name=' + $(this).val() + ')');
} else if (ageInput.val() !== "") {
url.attr('href', '/userinfo(age=' + ageInput.val() + ')');
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id="age" type="text" placeholder="age"/>
<input id="name" type="text" placeholder="name"/>
<a id="dynamic-url" href="/userinfo">
Submit
</a>
Hope it helps!

javascript funciton not being called

What's wrong in below code. It is not calling the function. After clicking compare it does not do anything. Function is not being called.
<!DOCTYPE html>
<html>
<body>
<input type="text" name="hash1" id="Hash1" placeholder="Enter First MD5" required>
<input type="text" name="hash2" id="Hash2" placeholder="Enter 2nd MD5" required>
<input type="button" value="Compare" onclick="myfn(); return false;" />
<script>
function myfn(){
document.write("Hello There");
hash1 = document.write(document.getElementsByName("hash1")[0].value;
hash2 = document.write(document.getElementsByName("hash2")[0].value;
action_src = hash1 + "/" + hash2;
document.write(acton_src);
}
</script>
</body>
</html>
You're missing some closing parenthesis on the hash variable definitions.
hash1 = document.write(document.getElementsByName("hash1")[0].value ) ;
hash2 = document.write(document.getElementsByName("hash2")[0].value ) ;
Also, I don't see why you need to return false on this line:
onclick="myfn(); return false;"
There is also a spelling error.
action_src = hash1 + "/" + hash2;
document.write(action_src);

Add “http://” or “https://” to a URL that contain only the relative url starting by "www"

Could someone help me to fix this little code to add the protocol “http://” or “https://” to a URL that contain only the relative url starting by "www"
<script>
function formatUrl(url)
{
var httpString = "http://";
var httpsString = "https://";
if (url.substr(0, httpString.length).toLowerCase() !== httpString && url.substr(0, httpsString.length).toLowerCase() !== httpsString)
url = httpString + url;
return url;
}
</script>
<form id=url type=get action='answers.asp' >
<input type=text name=URL size=10 value="" ><br><br>
<input type=submit name=url2 **onclick="formatUrl()"** value="Enter Url">
</form>
Input value = www.elmundo.es or any other relative url starting by www
thank you in advance
Actually this is a pretty simple task:
function formatURL(url)
{
if(url.substr(0,3) === "www")
{
return "https://"+url;
}
return url;
}
You may add some additional fail-safe checks (if the url is smaller than 3) - but you usually can check if the url starts with www, if so, you simply add the desired protocol to it (if I understood your question properly).
Ah, I guess now I got what you were asking for.
<script>
function formatURL()
{
var url = document.getElementsByName("URL")[0];
var formattedURL = document.getElementsByName("formattedURL")[0];
url = url.value;
if(url.substr(0,3) === "www")
{
formattedURL.value = "https://"+url;
return;
}
formattedURL.value = url;
}
</script>
<form id=url type=get action='answers.asp'>
<input type="text" name="URL" size=10 value="" onchange="formatURL()"><br><br>
<input type="hidden" name="formattedURL">
<input type="submit" value="Enter Url">
</form>
This will set the URL formatted into the hidden field formattedURL - however, this is only if you really want to do this in Javascript completely. I would do this on the server side, personally.

Google Recaptcha v3 example demo

Until now, I was working with Google Recaptcha v2, but now I want to update my WebApp using the lastest version (v3).
Is it possible to anyone add a fully working Google Recaptcha v3 example for a basic form as I can't find any working demos of it?
I'd really appreciate it.
Thank you very much.
PS: I'm using Java Servlets on the server side, but it doesn't matter if you explain using PHP or whatever.
Simple code to implement ReCaptcha v3
The basic JS code
<script src="https://www.google.com/recaptcha/api.js?render=your reCAPTCHA site key here"></script>
<script>
grecaptcha.ready(function() {
// do request for recaptcha token
// response is promise with passed token
grecaptcha.execute('your reCAPTCHA site key here', {action:'validate_captcha'})
.then(function(token) {
// add token value to form
document.getElementById('g-recaptcha-response').value = token;
});
});
</script>
The basic HTML code
<form id="form_id" method="post" action="your_action.php">
<input type="hidden" id="g-recaptcha-response" name="g-recaptcha-response">
<input type="hidden" name="action" value="validate_captcha">
.... your fields
</form>
The basic PHP code
if (isset($_POST['g-recaptcha-response'])) {
$captcha = $_POST['g-recaptcha-response'];
} else {
$captcha = false;
}
if (!$captcha) {
//Do something with error
} else {
$secret = 'Your secret key here';
$response = file_get_contents(
"https://www.google.com/recaptcha/api/siteverify?secret=" . $secret . "&response=" . $captcha . "&remoteip=" . $_SERVER['REMOTE_ADDR']
);
// use json_decode to extract json response
$response = json_decode($response);
if ($response->success === false) {
//Do something with error
}
}
//... The Captcha is valid you can continue with the rest of your code
//... Add code to filter access using $response . score
if ($response->success==true && $response->score <= 0.5) {
//Do something to denied access
}
You have to filter access using the value of $response.score. It can takes values from 0.0 to 1.0, where 1.0 means the best user interaction with your site and 0.0 the worst interaction (like a bot). You can see some examples of use in ReCaptcha documentation.
I thought a fully-functioning reCaptcha v3 example demo in PHP, using a Bootstrap 4 form, might be useful to some.
Reference the shown dependencies, swap in your email address and keys (create your own keys here), and the form is ready to test and use. I made code comments to better clarify the logic and also included commented-out console log and print_r lines to quickly enable viewing the validation token and data generated from Google.
The included jQuery function is optional, though it does create a much better user prompt experience in this demo.
PHP file (mail.php):
Add secret key (2 places) and email address where noted.
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
# BEGIN Setting reCaptcha v3 validation data
$url = "https://www.google.com/recaptcha/api/siteverify";
$data = [
'secret' => "your-secret-key-here",
'response' => $_POST['token'],
'remoteip' => $_SERVER['REMOTE_ADDR']
];
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
)
);
# Creates and returns stream context with options supplied in options preset
$context = stream_context_create($options);
# file_get_contents() is the preferred way to read the contents of a file into a string
$response = file_get_contents($url, false, $context);
# Takes a JSON encoded string and converts it into a PHP variable
$res = json_decode($response, true);
# END setting reCaptcha v3 validation data
// print_r($response);
# Post form OR output alert and bypass post if false. NOTE: score conditional is optional
# since the successful score default is set at >= 0.5 by Google. Some developers want to
# be able to control score result conditions, so I included that in this example.
if ($res['success'] == true && $res['score'] >= 0.5) {
# Recipient email
$mail_to = "youremail#domain.com";

I am assuming you have site key and secret in place. Follow this step.
In your HTML file, add the script.
<script src="https://www.google.com/recaptcha/api.js?render=put your site key here"></script>
Also, do use jQuery for easy event handling.
Here is the simple form.
<form id="comment_form" action="form.php" method="post" >
<input type="email" name="email" placeholder="Type your email" size="40"><br><br>
<textarea name="comment" rows="8" cols="39"></textarea><br><br>
<input type="submit" name="submit" value="Post comment"><br><br>
</form>
You need to initialize the Google recaptcha and listen for the ready event. Here is how to do that.
<script>
// when form is submit
$('#comment_form').submit(function() {
// we stoped it
event.preventDefault();
var email = $('#email').val();
var comment = $("#comment").val();
// needs for recaptacha ready
grecaptcha.ready(function() {
// do request for recaptcha token
// response is promise with passed token
grecaptcha.execute('put your site key here', {action: 'create_comment'}).then(function(token) {
// add token to form
$('#comment_form').prepend('<input type="hidden" name="g-recaptcha-response" value="' + token + '">');
$.post("form.php",{email: email, comment: comment, token: token}, function(result) {
console.log(result);
if(result.success) {
alert('Thanks for posting comment.')
} else {
alert('You are spammer ! Get the #$%K out.')
}
});
});
});
});
</script>
Here is the sample PHP file. You can use Servlet or Node or any backend language in place of it.
<?php
$email;$comment;$captcha;
if(isset($_POST['email'])){
$email=$_POST['email'];
}if(isset($_POST['comment'])){
$comment=$_POST['comment'];
}if(isset($_POST['token'])){
$captcha=$_POST['token'];
}
if(!$captcha){
echo '<h2>Please check the the captcha form.</h2>';
exit;
}
$secretKey = "put your secret key here";
$ip = $_SERVER['REMOTE_ADDR'];
// post request to server
$url = 'https://www.google.com/recaptcha/api/siteverify?secret=' . urlencode($secretKey) . '&response=' . urlencode($captcha);
$response = file_get_contents($url);
$responseKeys = json_decode($response,true);
header('Content-type: application/json');
if($responseKeys["success"]) {
echo json_encode(array('success' => 'true'));
} else {
echo json_encode(array('success' => 'false'));
}
?>
Here is the tutorial link: https://codeforgeek.com/2019/02/google-recaptcha-v3-tutorial/
Hope it helps.
We use recaptcha-V3 only to see site traffic quality, and used it as non blocking. Since recaptcha-V3 doesn't require to show on site and can be used as hidden but you have to show recaptcha privacy etc links (as recommended)
Script Tag in Head
<script src="https://www.google.com/recaptcha/api.js?onload=ReCaptchaCallbackV3&render='SITE KEY' async defer></script>
Note: "async defer" make sure its non blocking which is our specific requirement
JS Code:
<script>
ReCaptchaCallbackV3 = function() {
grecaptcha.ready(function() {
grecaptcha.execute("SITE KEY").then(function(token) {
$.ajax({
type: "POST",
url: `https://api.${window.appInfo.siteDomain}/v1/recaptcha/score`,
data: {
"token" : token,
},
success: function(data) {
if(data.response.success) {
window.recaptchaScore = data.response.score;
console.log('user score ' + data.response.score)
}
},
error: function() {
console.log('error while getting google recaptcha score!')
}
});
});
});
};
</script>
HTML/Css Code:
there is no html code since our requirement is just to get score and don't want to show recaptcha badge.
Backend - Laravel Code:
Route:
Route::post('/recaptcha/score', 'Api\\ReCaptcha\\RecaptchaScore#index');
Class:
class RecaptchaScore extends Controller
{
public function index(Request $request)
{
$score = null;
$response = (new Client())->request('post', 'https://www.google.com/recaptcha/api/siteverify', [
'form_params' => [
'response' => $request->get('token'),
'secret' => 'SECRET HERE',
],
]);
$score = json_decode($response->getBody()->getContents(), true);
if (!$score['success']) {
Log::warning('Google ReCaptcha Score', [
'class' => __CLASS__,
'message' => json_encode($score['error-codes']),
]);
}
return [
'response' => $score,
];
}
}
we get back score and save in variable which we later user when submit form.
Reference:
https://developers.google.com/recaptcha/docs/v3
https://developers.google.com/recaptcha/
I have seen most of the articles that don't work properly that's why new developers and professional developers get confused about it.
I am explaining to you in a very simple way. In this code, I am generating a google Recaptcha token at the client side at every 3 seconds of time interval because the token is valid for only a few minutes that's why if any user takes time to fill the form then it may be expired.
First I have an index.php file where I am going to write HTML and JavaScript code.
<!DOCTYPE html>
<html>
<head>
<title>Google Recaptcha V3</title>
</head>
<body>
<h1>Google Recaptcha V3</h1>
<form action="recaptcha.php" method="post">
<label>Name</label>
<input type="text" name="name" id="name">
<input type="hidden" name="token" id="token" />
<input type="hidden" name="action" id="action" />
<input type="submit" name="submit">
</form>
<script src="https://www.google.com/recaptcha/api.js?render=put your site key here"></script>
<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
setInterval(function(){
grecaptcha.ready(function() {
grecaptcha.execute('put your site key here', {action: 'application_form'}).then(function(token) {
$('#token').val(token);
$('#action').val('application_form');
});
});
}, 3000);
});
</script>
</body>
</html>
Next, I have created recaptcha.php file to execute it at the server side
<?php
if ($_POST['submit']) {
$name = $_POST['name'];
$token = $_POST['token'];
$action = $_POST['action'];
$curlData = array(
'secret' => 'put your secret key here',
'response' => $token
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.google.com/recaptcha/api/siteverify");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($curlData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$curlResponse = curl_exec($ch);
$captchaResponse = json_decode($curlResponse, true);
if ($captchaResponse['success'] == '1' && $captchaResponse['action'] == $action && $captchaResponse['score'] >= 0.5 && $captchaResponse['hostname'] == $_SERVER['SERVER_NAME']) {
echo 'Form Submitted Successfully';
} else {
echo 'You are not a human';
}
}
Source of this code. If you would like to know the explanation of this code please visit. Google reCAPTCHA V3 integration in PHP
For a "basic form" (as the original question asks) what's needed is simple if you're content to validate on the server. Here's a complete HTML page:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<script src="https://www.google.com/recaptcha/api.js"></script>
<script>
<!--
function onSubmit() {
var form = document.forms[0];
if ( form['name'].value ) {
form.submit();
} else {
alert( 'Please provide a name.' );
}
}
//-->
</script>
</head>
<body>
<form action="process.asp" method="post">
Name: <input type="text" name="name" /><br /><br />
<button class="g-recaptcha" data-sitekey="SITE_KEY" data-callback='onSubmit' data-action='contact'>Send</button>
</form>
</body>
</html>
And here's the complete page for processing it, using Classic ASP (filename = process.asp) for simplicity:
<%# Language=JavaScript %>
<%
var name = Request( 'name' ).Item;
var recaptchaResponse = Request( 'g-recaptcha-response' ).Item;
var ip = Request.ServerVariables( 'REMOTE_ADDR' );
var xmlhttp = Server.CreateObject( 'MSXML2.ServerXMLHTTP' );
var query = 'secret=SECRET_KEY&response=' + recaptchaResponse + '&remoteip=' + ip;
xmlhttp.open( 'POST', 'https://www.google.com/recaptcha/api/siteverify?' + query, false ); // false says to wait for response
xmlhttp.send();
var response = JSON.parse( xmlhttp.responseText );
Response.Write( name + ' is a ' + (response.success && response.action == 'contact' && response.score > 0.5 ? 'HUMAN' : 'ROBOT') );
%>
A few notes:
You'll supply your own SITE_KEY and SECRET_KEY.
You'll need a JSON parser.
You'll do the server-side POST using a method suitable for your
server.
I added one simple form field validation so you can see how to
integrate that.
You can make the "action" string anything you want, but be sure that
what's on the server is consistent with what's in the HTML.
You might want to respond differently to a response.success that
isn't true or a response.action that doesn't match your action
string, or do other error checking.
You might want a score conditional other than "> 0.5".
This code has no problems with the two-minute timeout.
I process POST on PHP from an angular ajax call. I also like to see the SCORE from google.
This works well for me...
$postData = json_decode(file_get_contents('php://input'), true); //get data sent via post
$captcha = $postData['g-recaptcha-response'];
header('Content-Type: application/json');
if($captcha === ''){
//Do something with error
echo '{ "status" : "bad", "score" : "none"}';
} else {
$secret = 'your-secret-key';
$response = file_get_contents(
"https://www.google.com/recaptcha/api/siteverify?secret=" . $secret . "&response=" . $captcha . "&remoteip=" . $_SERVER['REMOTE_ADDR']
);
// use json_decode to extract json response
$response = json_decode($response);
if ($response->success === false) {
//Do something with error
echo '{ "status" : "bad", "score" : "none"}';
}else if ($response->success==true && $response->score <= 0.5) {
echo '{ "status" : "bad", "score" : "'.$response->score.'"}';
}else {
echo '{ "status" : "ok", "score" : "'.$response->score.'"}';
}
}
On HTML
<input type="hidden" id="g-recaptcha-response" name="g-recaptcha-response">
On js
$scope.grabCaptchaV3=function(){
var myCaptcha = angular.element('#g-recaptcha-response').val();
var params = {
method: 'POST',
url: 'api/recaptcha.php',
headers: {
'Content-Type': undefined
},
data: {'g-recaptcha-response' : myCaptcha }
}
$http(params).then(function(result){
console.log(result.data);
}, function(response){
console.log(response.statusText);
});
}
if you are newly implementing recaptcha on your site, I would suggest adding api.js and let google collect behavioral data of your users 1-2 days. It is much fail-safe this way, especially before starting to use score.

Angular-input number from number pad to clicked textbox

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.count = ''
});
</script>
</head>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
<button id="btn1" ng-click="count = count + 1">1</button>
<button id="btn2" ng-click="count = count + 2">2</button>
<label>Textbox1</label><input type="text" id="Textbox1" value="{{count}}"/>
<label>Textbox2</label><input type="text" id="Textbox2" value="{{count}}"/>
</div>
</body>
</html>
Now if I click on Textbox1 then click on button 1 or 2 text should be only on Textbox1 not textbox2
is it possible to bind value to value using ng-click like this
function on controller
$scope.change = function(evt) {
evt.target.value={{count}};
alert(evt.target.id)
html
<label>Textbox1</label><input type="text" id="Textbox1" value="{{count}}" ng-click="change($event)"/>
<label>Textbox2</label><input type="text" id="Textbox2" value="{{count}}" ng-click="change($event)"/>
or some other way
I'm not 100% sure I understood what you want to do, but if I'm right, this should do what you want:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.count = 0;
$scope.field1count;
$scope.field2count;
$scope.selectedField = 0;
$scope.calculateField = function(amount){
var result = $scope.count + amount;
$scope.count = result;
if($scope.selectedField == 1){
$scope.field1count = result;
} else if($scope.selectedField == 2){
$scope.field2count = result;
}
}
});
</script>
</head>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
<button id="btn1" ng-click="calculateField(1)">1</button>
<button id="btn2" ng-click="calculateField(2)">2</button>
<label>Textbox1</label>
<input type="text" id="Textbox1" ng-focus="selectedField = 1" ng-model="field1count"/>
<label>Textbox2</label>
<input type="text" id="Textbox2" ng-focus="selectedField = 2" ng-model="field2count"/>
</div>
</body>
</html>
If you want the two input fields to display different values, you need to actually assign them different values, as angular's two-way-binding means the value will be updated in both the model and the controller simultaneously.
Ng-focus can also be replaced by ng-click in this case, if you prefer using that. Ng-focus is triggered when the input field gains focus (When you use, for example, the tab key to reach the field, this will also be triggered), while ng-click does so when the field is clicked upon.
In this example ng-model="field1count" can also be replaced with value="{{field1count}}", as you did in your example, but the use of ng-model is more appropriate to the use of angular.
Working snippet:
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.count = 0;
$scope.field1count;
$scope.field2count;
$scope.selectedField = 0;
$scope.calculateField = function(amount){
var result = $scope.count + amount;
$scope.count = result;
if($scope.selectedField == 1){
$scope.field1count = result;
} else if($scope.selectedField == 2){
$scope.field2count = result;
}
}
});

You should use two separeted ng-model on your input if what you want is to output two different datas.
But I'm not really sure of what you want to do here .. Can you try to explain it a bit more ?

Opacity of div container with background-color style

I have a fix colorstring like "#ff0000" and I set this fix string like this (with AngularJS):
<div style="background-color: {{chatMessageOfUser.color}};">...
Now I will set an opacity only to the background-color. Actually I dont know how to do this without splitting the chatMessageOfUser.color- string?
HTML
ng-class="{'opacityclass': chatMessageOfUser.color == '#ff0000'}"
CSS
.opacityclass
{
opacity :0.5
}
HTML
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<style>
.opacityclass
{
opacity :0.5
}
</style>
<body ng-app="myApp" ng-controller="myCtrl">
<h1 ng-style="myObj">Welcome</h1>
<h1 ng-class="{'opacityclass': chatMessageOfUser.color == '#ff0000'}">Welcome</h1>
<table>
<tr ng-repeat="x in names">
<td>{{ x.Name }}</td>
<td ng-class="{'opacityclass': x.color == '#ff0000'}">{{ x.Country }}</td>
</tr>
</table>
<script>
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
$scope.names = [
{"Name":"Alfreds Futterkiste","City":"Berlin","Country":"Germany" , "color":"#00000"},
{"Name":"Ana Trujillo Emparedados y helados","City":"México D.F.","Country":"fdgdgdg" ,"color":"#066000"},
{"Name":"Antonio Moreno Taquería","City":"México D.F.","Country":"yuiyui" ,"color":"#ff0000"}
]
$scope.chatMessageOfUser ={
"color" : "#ff0000",
}
});
</script>
</body>
</html>

If I understood your question correctly you will need to split your input. You can do this in a filter however.
Here is some rough example (note that this is not production ready since you still need input validation, ...):
.filter('color', function()
{
return function(colorString, opacity)
{
opacity = opacity || 1;
colorString = colorString.replace('#', '');
var splitColor = colorString.match(/.{1,2}/g);
splitColor = splitColor.map(function(hex) { return parseInt(hex, 16); });
return 'rgba(' + splitColor[0] + ', ' + splitColor[1] + ', ' + splitColor[2] + ', ' + opacity + ')';
}
});
The usage of this snippet would be
<div class="colorField" style="background-color: {{colorInput | color:colorAlpha}}">
See this fiddle to see it in action.
