Can I change an input field value using CSS when user clicks it?
Like:
<input type=text name=username>
<input type=password name=password>
So, when the user click into this field, the text will go away and he will be able to write something.
I have tried:
input[value="Input desired username here"] {
styles...
}
Any clues?
There's no need to use css for this. You can use placeholder attribute for your input tag, it will show a default value in input boxes:
<input type="text" name="username" placeholder="Username" />
Please consider that placeholder attribute is not supported in all browsers and if you want to make it cross-browser you can write a javascript code to put a default value in your input-boxes or use this simple and quick fix:
<input type="text" name="username" onFocus="if(this.value=='Username') this.value='';" onBlur="if(this.value=='') this.value='Username';" value="Username" />
This is called a placeholder. Modern browsers will allow you to use a placeholder attribute like this:
<input type="text" name="username" placeholder="Input desired username here" />
and it will appear as you would like. Then you will need to utilize Modernizr to back port that functionality to older browsers. Something like this JavaScript will help:
$(document).ready(function () {
if(!Modernizr.input.placeholder) {
$('[placeholder]').focus(function () {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
input.removeClass('placeholder');
}
}).blur(function () {
var input = $(this);
if (input.val() == '' || input.val() == input.attr('placeholder')) {
input.addClass('placeholder');
input.val(input.attr('placeholder'));
}).blur();
$('[placeholder]').parents('form').submit(function () {
$(this).find('[placeholder]').each(function () {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
}
})
});
}
})

Hello I'm trying to get my contact form to display a thank you message after the message has been sent.
I looked around but the stuff I find looks more complex than what I think i need.
I think it's something i'm missing about the event listener and how this form works.
Here's my code:
.thanks {
display: none;
}
<div class="form-wrap">
<form class="contact-form" action="https://getsimpleform.com/messages?form_api_token=aa0a1c58e87ea8816ba9ff7d7a71d0ef" method="post">
<!-- all your input fields here.... -->
<div class="name-email">
<input class="contact-field contactform-name" type='text' name='name' placeholder="Name" required/>
<input class="contact-field contact-form-email" type="email:" name="email" placeholder="e-mail" value="" required>
</div>
<textarea class="contact-field" name="message" rows="20" cols="80" placeholder="Your Message" required></textarea>
<input class="contact-field submit" type='submit' value='Send' />
</form>
</div>
<div class="thanks">
<h1>Thanks for the message!</h1>
</div>
<script>
function displayThanks() {
document.querySelector(".thanks").style.display = "block";
document.querySelector(".contact-form").style.display = "none";
}
document.querySelector(".submit").addEventListener("submit", displayThanks)
</script>
I could make it work on click, but that would mean that even if they don't send a message and just click submit they will get thank you (FOR WHAT!?)
Thanks!

You are mixing client side logic with server side logic. It's hard to answer your question because we don't know, what the action "action="https://getsimpleform.com/messages?form_api_token=aa0a1c58e87ea8816ba9ff7d7a71d0ef" in your form tag is doing.
It might be usefull to validate the form, before you consider to submit it. You can do this by using the click event of the submit button in combination with preventDefault like this (Just an Example, you could even use RegEx for emails and stuff):
document.querySelector(".submit").addEventListener('click', function(e) {
var userInputName = document.getElementsByName("name")[0].value,
userInputEmail = document.getElementsByName("email")[0].value,
userInputMessage = document.getElementsByName("message")[0].value;
if (userInputName.length > 0 && userInputEmail.length > 0 && userInputMessage.length > 0)
{
document.querySelector(".thanks").style.display = "block";
document.querySelector(".contact-form").style.display = "none";
}
else
{
e.preventDefault();
}
}, false);
I would recommend to use IDs instead of names though, because IDs are unique and don't require a node list or ambiguous jQuery. Than you can use something like this: userInputName = document.getElementById("name").value;
And don't forget to use the right CSS for your logic. Like:
.thanks {display: none;}
I have a list of multiple checkboxes in the form. The user can check all the checkboxes but at least one is required. Without selecting at least one, checkbox they should not be able to submit the form. how to make it in contact form 7?
I have added the script which is not working.
Here is my script
$(document).ready(function () {
$('#checkBtn').click(function() {
checked = $("input[type=checkbox]:checked").length;
if(!checked) {
alert("You must check at least one checkbox.");
return false;
}
});
});
In this only write star(*) after checkbox element in the plugin form
[checkbox* checkbox "test 1" "test 2"]
[submit "Send"]
It is perfectly work.
On this set your code
$('#fm_submit').submit(function(e){
e.preventDefault();
var ck_box = $('input[type="checkbox"]:checked').length;
// return in firefox or chrome console
// the number of checkbox checked
console.log(ck_box);
if(ck_box < 1){
alert('Select any one box');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form name = "frmTest[]" id="fm_submit">
<input type="checkbox" value="true" checked="true" >
<input type="checkbox" value="true" checked="true" >
<input type="checkbox" >
<input type="checkbox" >
<input type="submit" id="fm_submit" name="fm_submit" value="Submit">
</form>
<div class="container"></div>
Paste the code from above on the bottom of the form instead of the Additional Settings
$('#fm_submit').submit(function(e){
e.preventDefault();
var ck_box = $('input[type="checkbox"]:checked').length;
// return in firefox or chrome console the number of checkbox checked enter code here
console.log(ck_box);
if(ck_box < 1){ alert('Select any one box'); }
});
I want to find the default tab index of the form.
I have not given but still all the control has the tab index. I want to find that default tab index through the j query. How can i find that?
Jquery and tab-index
The way tabindexing works is that it goes trough your html markup and looks for tabable elements.
So say you have this code:
<form>
<label>Name:</label>
<input type="text" />
<br>
<input type="submit" />
</form>
The text input will be tabbed first, and then the submit input.
Yes i know this how do it get the tabbing?
$(function() {
$firstinput = $("form").find("input")
console.log($firstinput.first()); //prints the first element thats an input.
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<label>Name:</label>
<input type="text" />
<br>
<input type="submit" />
</form>
The code above will only work if you only have input elemtns and add not trickery to the markup like hiding your elements etc.
In the code below im using the jquery UI :focusable selector.
With this you should get the first tabbable element in your form
//:focus selector from jquery UI
$.extend($.expr[':'], {
focusable: function(element) {
var nodeName = element.nodeName.toLowerCase(),
tabIndex = $.attr(element, 'tabindex');
return (/input|select|textarea|button|object/.test(nodeName) ? !element.disabled : 'a' == nodeName || 'area' == nodeName ? element.href || !isNaN(tabIndex) : !isNaN(tabIndex))
// the element and all of its ancestors must be visible
// the browser may report that the area is hidden
&& !$(element)['area' == nodeName ? 'parents' : 'closest'](':hidden').length;
}
});
//actual code
$(function() {
$form = $("form");
$first = $form.find(":focusable").first();
console.log($first);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<label tab-index="0">Name:</label>
<input type="text" />
<br>
<input type="submit" />
</form>
You can search for 'tabindex' attribute with jquery.
var tabindexVal = $('selector').attr('tabindex');
I am new to angular js. and I have a situation.
I want to bind data to an input element from another input element based on a condition (checking a checkbox). I am trying to achieve this using the
ng-if angular directive. But it's not working,
So when I type something into input1 and check the checkbox, I want the value of input1 to be reflected in input2.
<input ng-model="value.one" type="text" />
<input ng-model="checked" ng-change="isChecked(value.one)" type="checkbox" />
<input ng-model="value.selected" />
in your controller:
$scope.isChecked(val) {
if($scope.checked) {
$scope.value.selected = val;
} else {
$scope.value.selected = null;
}
}
I'm currently doing the following to compensate for boolean's not mapping well to radio buttons. I am stuck binding 1 and 0 to the value (instead of true and false) because of how the fields are read out of the observables. The value of Pref1/Pref2 come as true/false boolean values from the server. The key here is I want to not only data-bind the checked value of the radio button to match the true/false in the object, but I also want the boolean value of true/false to be written back into the GraduationClass object. My compensation code is not only ugly, but not scalable.
<input type="radio" value="1" name="radioGroup" data-bind="checked: Pref1" />Yes
<input type="radio" value="0" name="radioGroup" data-bind="checked: Pref2" />No
Save
function SiteSettingsViewModel() {
var self = this;
this.saveGraduationClass = function(graduationClass) {
// hack until i get a custom radio button binding
if (graduationClass.Pref1() == 1) {
graduationClass.Pref1(true);
} else {
graduationClass.Pref1(false);
}
if (graduationClass.Pref2() == 1) {
graduationClass.Pref2(true);
} else {
graduationClass.Pref2(false);
}
// ...ajax call to save graduationClass to the server
}
function GraduationClass(data) {
var self = this;
ko.mapping.fromJS(data, {}, this);
}
Here is example from knockoutJs website, that demonstrate how to use radio buttons with
"checked" attribute:
<p>Send me spam: <input type="checkbox" data-bind="checked: wantsSpam" /></p>
<div data-bind="visible: wantsSpam">
Preferred flavor of spam:
<div><input type="radio" name="flavorGroup" value="cherry" data-bind="checked: spamFlavor" /> Cherry</div>
<div><input type="radio" name="flavorGroup" value="almond" data-bind="checked: spamFlavor" /> Almond</div>
<div><input type="radio" name="flavorGroup" value="msg" data-bind="checked: spamFlavor" /> Monosodium Glutamate</div>
</div>
<script type="text/javascript">
var viewModel = {
wantsSpam: ko.observable(true),
spamFlavor: ko.observable("almond") // Initially selects only the Almond radio button
};
// ... then later ...
viewModel.spamFlavor("msg"); // Now only Monosodium Glutamate is checked
</script>
But I dont understand why you use two objects - "Pref1" and "Pref2" fro one radiobutton group "radioGroup"? In this case you just could use one object as in an example used "spamFlavor".
So, please, describe more ditaily what you want to bind: one radiobuttons group by one selected value, or something else.
Also you could use computed observables to calculate different values, please see example.
