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();
}
);

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.
$('#query-string').keypress(function(event) {
if (event.keyCode == 13) {
searchWiki();
event.preventDefault();}});
I have following form
<form id="myForm" action="/Problems/Post" method="post" enctype="multipart/form-data">
<input type="text" id="problemSubject" name="problemSubject" />
<input type="file" id="uploadFile" name="uploadFile"/>
<textarea rows="" cols="" class="form-textarea" id="problemDescription" name="problemDescription"></textarea>
</form>
I have to submit form to controller method(which i have done), but it should be first validated i.e. it should not contain empty fields. What i want is that "a message should appear telling that field is blank". How this can be done. Please help me. Thanks.
Take a look at some of the samples. (http://www.asp.net/mvc/tutorials/older-versions/javascript/creating-a-mvc-3-application-with-razor-and-unobtrusive-javascript)
Essentially you can validate on client side and on server side, which you should do both.
It is very easy to do validation in asp.net mvc3. Look at some tutorials like above.
Or this one: http://www.codeproject.com/Articles/249452/ASP-NET-MVC3-Validation-Basic
u can use server side validation controls...
plz hv a look [link]http://msdn.microsoft.com/en-us/library/aa479013.aspx
or use the jquery gven below--->
function callOnload(){
if($('#problemSubject').val() == '')
alert('fill the values');
if($('#uploadFile').val() == '')
alert('fill the values');
}
I am writing a form using jQuery and encounter some difficulties.
My form works fine in static page (html).
However, when I use the form in dynamic page(aspx), the form does not behave correctly.
I cannot append items to the form and call the form.serialize function.
I think the error occurs when a form is inside another form (.aspx code needs to enclosed by a form tag).
What should I do?
Let me give a simplified version of my code:
<form name="Form1" method="post" id="Form1">
some content
<form name="form_inside">
<input name="fname" type="text" />
</form>
</form>
jQuery code:
$("#form_inside").append($("<input type='text' name='lname'>"));
When the user submits,
$("#form_inside").serialize();
// it should return fname=inputfname&lname=inputlname
I want to append element to "form_inside" and serialize the form "form_inside".
The form "Form1" is required by the aspx and I cannot remove it.
Could you just serialize the fields inside Form1?
I don't know anything about ASP, but it seems that you're not doing a straightforward "submit" anyway - so does it really matter if the fields aren't within their own separate form?
You could possibly group the fields you're interested in within a <div> or something, e.g.:
<div id="my-interesting-fields">
...
</div>
then substitute #form-inside with #my-interesting-fields where appropriate - is that helpful at all?
Edit
OK, a quick glance at the jQuery code suggests that serialize() depends on the form's elements member.
I suppose you could hack this in a couple of different ways:
Copy all elements from #my-interesting-fields into a temporary <form> that you dynamically create outside Form1, then call serialize() on that. Something like:
$("#Form1").after("<form id='tmp-form'></form>").
append("#my-interesting-fields input");
$("tmp-form").serialize();
Or, create an elements member on #my-interesting-fields, e.g.
$("#my-interesting-fields").elements = $("#my-interesting-fields input");
$("#my-interesting-fields").serialize();
I haven't tried either of these, but that might give you a couple of ideas. Not that I would necessarily recommend either of them :)
Because you can't have nested <form> tags you'll need to close off the standard dotnet form tag like below:
<script type="text/javascript">
$(document).ready(function() {
$("#form_inside").append($("<input type='text' name='lname'>"));
$("#submitBtn").click(function() {function() {
var obj = $("#form_inside *");
var values = new Array();
obj.each(function(i,obj1) {
if (obj1.name && !obj1.disabled && obj1.value) {
values.push(obj1);
};
});
alert(jQuery.param(values));
}); });
});
</script>
<form id="form1" runat="server">
<div>
<div id="form_inside" name="form_inside"> <input name="fname" type="text" /><input type="button" id="submitBtn" /></div>
</div>
</form>
jQuery.param on a array of form elements will give you the same results as .serialize()
so you get all elements in div $("#form_inside *) then filter for elements then on the result jQuery.param will give you exactly what you need
Google custom search code is provided as a form tag. However, Asp.net only allows a single form tag on a page. What is the best way to implement their code so you can include it on an aspx page (say as part of a Masterpage or navigation element).
You can have multiple form tags on an ASP.NET page. The limitation is on server-side (runat="server") form tags.
You can implement two form tags (or more) as long as only one has the runat="server" attribute and one is not contained in the other. Example:
<body>
<form action="http://www.google.com/cse" id="cse-search-box"> ... </form>
<form runat="server" id="aspNetform"> ... </form>
<body>
You may be able to have multiple form tags, but note that they cannot be nested. You'll run into all kinds of weirdness in that scenario (e.g., I've seen cases where the opening tag for the nested form apparently gets ignored and then its closing tag winds up closing the "parent" form out).
You'll need to remove the form tag and use javascript send the query. Have a look at
http://my6solutions.com/post/2009/04/19/Fixing-Google-Custom-Search-nested-form-tags-in-asp-net-pages.aspx
I have included the before and after code as well. So you can see what I've done to integrate it with blogengine .net.
You could use Javascript:
<input name="Query" type="text" class="searchField" id="Query" value="Search" size="15" onfocus="if(this.value == 'Search') { this.value = ''; }" onblur="if(this.value == '') { this.value = 'Search'; }" onkeydown="var event = event || window.event; var key = event.which || event.keyCode; if(key==13) window.open('http://www.google.com/search?q=' + getElementById('Query').value ); " /><input name="" type="button" class="searchButton" value="go" onclick="window.open('http://www.google.com/search?q=' + getElementById('Query').value );" />
