JQuery :: How To Validate Web Form Before Submitting
Feb 1, 2010
I have a asp.net web form that I need to validate before submitting. I've tried the AJAX Control Toolkit but I was having problem with multiple ValidationSummary control conflict. So, my next option I can think of is to use jQuery. First of, how do I test to see if a textbox is blank or not? If blank, output a message to a asp.net Label control on the page and stop the web form submission. Second, if the validation succeeds, proceeds to submitting the web form.

I have a submit button on my form. However, I would like to do validation before submitting. I would submit the form values only if the validation has passed. How can I do that? Can I have an example please.
I have the following code:
<input type ="text" id="password"/> <input type="text" id="confirmPassword"/><label for="err"></label><input type="submit" value=Save/>

I am pretty comfortable with jQuery and the validation plugin as well.
I am having an issue where:
User clicks a button it opens a lightbox (I am using Fancybox) - a form appears inside the modal. The data is submitted via AJAX and I am trying to validate the form before the form within the lightbox is submitted.
My button with the click handler right now does a GET to a server to send the data. Along with some other JavaScript. What is the best way for me to validate my form within a lightbox, and submit after it validates. Sending AJAX.

I've a page that has 2 forms. If the user clicks the bottom form the validations appear and everything goes red but the Top form is a required field but it doesn't as it's a separate form. How can I validation form0 and form1 together to show to the user the required fields. When the user clicks form0 it goes over to a pagedLIst, the user returns and textfield gets populated with the product that as selected. So when they hit form1, that value gets passed through as a hiddenfield..
<form id="form0">
...text box input to search for your product, returns to this page populated the found product
<input class="button" id="FindProduct" type="submit" value="Find Product" name="action"/>

I have a form. Upon submit, the data is sent to the server. Under certain conditions, the form is replaced via ajax with a set of radio buttons that offer the user a a choice.I need to access the radio buttons before I submit the form again.Normally I could just access the buttons with getelementbyid but it is not available, presumably because they were generated via ajax.I could submit the form just to access the radio buttons and then submit it again, but I'd like to avoid that.

I have the following code:
$('input#submit').click(function()
{
//check if compulsory forms are filled
if ( //checks if forms are filled)
[Code]....
the whole idea is to submit the form in the *else* block if the condition that all compulsory fields are filled (which is checked in the IF block)...but this only works in Firefox. in chrome and IE, the code execution does not go pass the "Processing Form Submission Please Wait" that is shown. The *return true* line never gets executed which is the one that actually send the form...

I want the "play" button to perform ajaxSubmit (Form plugin) submitting a bunch of fields on the form in which these buttons are contained. This will start a simulation based on the passed in parameters.I want the other bottons to send signals to the server to control the simulation. They don't really need to send parameters. I presume I can just do this with something like jQuery.post().
Here's my problem. All of the buttons in my toolbar just submit the form, presumably because they are buttons declared within the same <form></form>. (I copied the code for these buttons directly from the jQuery UI demo toolbar.)My initial thought was to use the Form plugin somehow detect which button was clicked or something like that, but I can't figure out how to do that.How do I make the play button submit the form, while the other buttons do different jQuery.post() calls? Or is there a better way ofachievingthe result I want?

I've got so far:
Btw this is within a wordpress page.
I've tried the regular "$(document).ready(function() {" as well.

I have a small problem with a form. After I click on a submit button a small animation starts, I would like to submit form after animation but nothing is working. I tried different methods and I also checked html for errors.
Code of function:
$(document).ready(function(){
$("#button").click(function() {
var productX = $("#first").offset().left;
var productY = $("#first").offset().top;
var basketX = $("#basket").offset().left+15;
var basketY = $("#basket").offset().top+20;
var gotoX = basketX - productX;
var gotoY = basketY - productY;
var newImageWidth = $("#first img").width() / 3;
var newImageHeight = $("#first img").height() / 3;
$("#first img") .....
.clone()
.prependTo("#first")
.css({'position' : 'absolute'})
.animate({opacity: 0.9}, 100 )
.animate({opacity: 0.6, marginLeft: gotoX, marginTop: gotoY, width: newImageWidth, height: newImageHeight}, 1200, function(){
$("#detailstext").submit(); //form id
});
return false;
});
});
I also tried
$("form_id").post(0).submit();
but i got error:
$("form_id").post is not a function

I have a form with about 10 fields, and the action is sent to a php file which processes the form. Now, I also like to use a Thickbox such that the user can preview the page before actually submitting it to the process.php. That means, I have one submit button and one href, which href links to an iFrame thickbox to preview the page. My problem is that I don't know how to obtain the input values in the iFrame, without user clicking on submit (rather i want to get the values through href). something like the preview on this forum, except I want it on thickbox.

How to send one input data using ajax, I then needed to send a form with multiple inputs. I believe I can't do this with AJAX so have tried to implement it using JQuery.
The problems I am having is that my page is refreshing when I click on submit and the data is not being sent.
I am more than happy to look at other ways to do this if JQuery is not the answer. All I want is a page that doesn't refresh or redirect but does submit a form.
My form is:

I've got some strange behavior with validation. I'm loading up a form to allow editing of an existing database entry. If I make my changes to the fields, enter in the required "revision comments" and submit, the page does NOT post, it seems to only refresh and empty out all the entries in each of the fields. Now, on the other hand if I open the form to make changes to a database entry and immediately press "Submit" without filling in the revision comments field, it fails validation and tells me to enter comments. Now if I fill in comments to satisfy all the requirements and press submit, it posts and I get my "Successful Entry" confirmation prompt. I think I've narrowed it down to the remote: part of my jQuery. I eliminated by trial-and-error the other pieces of the jQuery code and it seems that when I remove the remote: it does not experience this strange behviour.
jQuery Code:

// Form Validation customization
$("#Form_business").validate({
rules: {
