I have following form
<form id="myForm" action="/Problems/Post" method="post" enctype="multipart/form-data">
<input type="text" id="problemSubject" name="problemSubject" />
<input type="file" id="uploadFile" name="uploadFile"/>
<textarea rows="" cols="" class="form-textarea" id="problemDescription" name="problemDescription"></textarea>
</form>
I have to submit form to controller method(which i have done), but it should be first validated i.e. it should not contain empty fields. What i want is that "a message should appear telling that field is blank". How this can be done. Please help me. Thanks.
Take a look at some of the samples. (http://www.asp.net/mvc/tutorials/older-versions/javascript/creating-a-mvc-3-application-with-razor-and-unobtrusive-javascript)
Essentially you can validate on client side and on server side, which you should do both.
It is very easy to do validation in asp.net mvc3. Look at some tutorials like above.
Or this one: http://www.codeproject.com/Articles/249452/ASP-NET-MVC3-Validation-Basic
u can use server side validation controls...
plz hv a look [link]http://msdn.microsoft.com/en-us/library/aa479013.aspx
or use the jquery gven below--->
function callOnload(){
if($('#problemSubject').val() == '')
alert('fill the values');
if($('#uploadFile').val() == '')
alert('fill the values');
}

I have a simple problem yet it seems impossible to solve in AMP!!
I have a simple form with an input and a submit button like this:
<form id="myform">
<input type="text" id="srchInput"/>
<button type="submit">Submit</button>
</form>
All I want is to be able to concat a static url to the input value and redirect the page to the result, when the form is submitted.
For instance if the user inputs: "Hello" and submits the form, I would like to redirect him to a page like "MY/STATIC/URL/Hello".
Is there any way to achieve this in amp?
One way of doing this is by setting the AMP-Redirect-To header in the response (See AMP-form-redirection). Send the user input on form submission, and then generate your desired url from your API endpoint and set AMP-Redirect-To header in your response to the generated URL.
Another way of doing it would be by using navigateTo(url=STRING) action (See AMP Actions & Events) on for the form submit event. In this case you have to store the value in input to a state by using events like input-throttled, and then use url substitution in the navigateTo url string to append amp-state value.
The first method is guaranteed to work.
The second method should work in theory, but I was unable to figure out how to get AMP-STATE value by url substitution. The code for the same should be something like:
<form id="myform" on="submit:AMP.navigateTo(url="MY/STATIC/URL/AMP_STATE(endValue)>")">
<input type="text" id="srchInput" on="input-throttled:AMP.setState({ endValue : event.value })" />
<button type="submit"> Submit </button>
</form>
If you can figure out how to substitute amp-state value to the url this should work. Let me know if it helped.
The easiest way to do this is via a GET action:
<head>
...
<script async custom-element="amp-form" src="https://cdn.ampproject.org/v0/amp-form-0.1.js"></script>
</head>
<body>
<form method="GET" action="MY/STATIC/URL" target="_top">
<input type="text" id="srchInput" name="srcInput" value="test">
<button type="submit">Submit</button>
</form>
</body>
The form submit will navigate to /MY/STATIC/URL?srcInput=test.
I have a form in my ASP .NET project that takes the users input, and appends it to a URL to search a wiki. The form works perfectly when you enter in a search term, and click the 'search' button, however when you type into the input box and hit enter, the page refreshes and the box clears.
my html
<form>
<label id="sideBarLabel"> Services
<input type="text" placeholder="Search Wiki: e.g. E911" name="queryString" id="query-string" />
</label>
Search Wiki
</form>
my js
function searchWiki(){
var siteQuery = $('#query-string').val();
window.location.href = "/dosearchsite.action?queryString=" + siteQuery;
}
Can anyone help ?
Your searchWiki() js method is only called when the evenement onclick is raised on your button, but not when your form is submitted.
There is several ways to achieve what you want:
Add a js method to catch the onsubmit event of your form:
$("form").on("submit", searchWiki());
Or add a tag on your form:
<form onsubmit="searchWiki()">
Or specify the action attribute on your form:
<form action="/dosearchsite.action">
Note that in ASP.NET, the ModelBinder will link your form inputs to your controller action parameters, using the name attribute of the inputs. That means that you should not specify them in the url yourself.
You should also declare your form using Html.BeginForm or Ajax.BeginForm if you want your form to be submitted by ajax.
#Html.BeginForm("ActionName", "ControllerName")
{
<label id="sideBarLabel">Services
<input type="text" placeholder="Search Wiki: e.g. E911" name="queryString" id="query-string" />
</label>
<input type="submit" class="button" value="Search Wiki"/>
}
This will call searchWiki when you press enter.
$('#query-string').keypress(function(event) {
if (event.keyCode == 13) {
searchWiki();
event.preventDefault();}});
i have a html form into my database.
In this form i have a value which contains a Viewbag,
for example value="#Viewbag.MyVariable"
In my view when i try to receive my form all works fine,
but my problem is that the Viewbag value are not converting
to the value which comes from my controller.
any ideia how to resolve this ?
my code:
View:
#Html.Raw(p.Form)
My form in my database looks like:
<form action="/MyController/MyAction" method="post">
<input type="hidden" name="num" value="#ViewBag.num" />
....
....
....
</form>
What i have try to do was with:
Stringbuilder a=new Stringbuilder;
#Html.Raw(a.To.String())
Your code should technically work, if you are using MVC you could try
#MvcHtmlString.Create(p.Form);
I found a solution and now i solved it.
what i have done:
in my form the only part which are different from the others
forms are the dropdownlists.
i only put the part from <select> to </select> in my
database. (only the dynamically part of my form)
in my view i have write my form and only insert the variable
which comes from my controller to insert the data from my
database on the right part in my form.
here is the code:
<form action="/MyController/MyAction" method="post">
<input type="hidden" name="num" value="#ViewBag.num" />
#MvcHtmlString.Create(p.Form);
<button type="submit" name="submit" id="submit">OK</button>
</form>
So i have never more the problem with the variables to be
converted, because the variables are still the same
I have a site that has 2 forms - a short form and a long form. If you look at http://dforbesinsuranceagency.com you'll see the short form next to the masthead photo. The long form is at http://dforbesinsuranceagency.com/request-free-insurance-quotes/
When the user hits Submit on the short form, it kicks them over to the long form page, so that part works fine. The part that gives me fits is that I need the values entered into the short form fields First Name, Last Name, Email Address and Telephone passed to their equivalent fields on the long form.
How do I do this?
This is how I am redirecting the short form to the long form (I added it to the Additional Settings section for the short form):
on_sent_ok: "location = 'http://dforbesinsuranceagency.com//request-free-insurance-quotes';"
Any help would be appreciated.
Hack, hack, hackety, hack hack hack... Without suggesting "not using a form-builder" I don't think there is an elegant solution - you can't use the other PHP method suggested without modifying the plugin itself (and that is a can of worms). I will propose a Javascript solution but there are some caveats (below):
jQuery(document).ready(function($){
$('#quick-quote form:first').submit(function(){
var foo = {};
$(this).find('input[type=text], select').each(function(){
foo[$(this).attr('name')] = $(this).val();
});
document.cookie = 'formData='+JSON.stringify(foo);
});
var ff = $('#container form:first');
if(ff.length){
var data = $.parseJSON(
document.cookie.match('(^|;) ?formData=([^;]*)(;|$)')[2]
);
if(data){
for(var name in data){
ff.find('input[name='+name+'], select[name='+name+']').val(data[name]);
}
}
}
});
What this will essentially do is: on submission, store your mini-form options in a cookie. On page load it will then look for a form in the main body of the page and apply any stored cookie data.
Notes
The jQuery selectors are deliberately ambiguous to avoid any future changes in your admin panel/plugin that will likely screw with the form IDs (thus breaking the script).
I'm not faffing about pairing field/option names - for example the select box in your mini-form is named insurance-type however the matching box in the main form is named ins-type - you will have to ensure they are of the same name.
This also applies to select box values - if there is no matching value, it will be ignored (eg. some of your values in the main form have » » characters in front (and so don't match).
try this.
set the action of our first form to a php file named xyz.php
<form method="post" action="xyz.php">
<input type="text" name="name">
<input type="text" name="email_address">
<input type="submit" value="Go To Step 2">
</form>
the file xyz.php will create a new form for you which in this case is your second form (the big one). Set the action of the form as required. the code of your xyz.php will look something like this.
<form method="post" action="form3.php">
<input type="text" name="name" value="<?php echo $_POST['name']; ?>">
<input type="text" name="email_address" value="<?php echo $_POST['email_address']; ?>">
<input type="radio" group="membership_type" value="Free">
<input type="radio" group="membership_type" value="Normal">
<input type="radio" group="membership_type" value="Deluxe">
<input type="checkbox" name="terms_and_conditions">
<input type="submit" value="Go To Step 3">
</form>
where the input fields of the first form will already be filled with the details given by the user in the first form.
You can create the first form by yourself and let the contact form create the second form for you providing the default values using the method above.
Hope this helps!
i have requirement to create form on the fly like html below
<form action='http://www.example.com' method='POST' name=''>
<input type='HIDDEN' name='' value=''>
<input type='HIDDEN' name='Username' value=''>
<input type='HIDDEN' name='password' value=''>
<input type='SUBMIT' value='Go'>
</form>
to the form once this form created it should automatically get post on page load in asp.net.
This is can not actually post on PageLoad. You can post it automatically only using javascript after you have render the html page.
This article have a source code on how to create this form dynamically on asp.net and automatically make the post. Is done exactly what you ask for.
http://www.codeproject.com/Articles/37539/Redirect-and-POST-in-ASP-NET
From the previous answer by #Aristos, I have checked the link and I have learnt too. You can check it out
You can also use javascript to post the form when the page load
...your forms tags here
<script type="text/javascript">
document.forms['form_name'].submit();
</script>
</body>
</html>
Just make sure the script is the last element in the DOM or use jQuery
$(document).ready(function()
{
document.forms['form_name'].submit();
}
);
