Get A Validation Script To Work?
Oct 5, 2009
I am trying to get a validation script to work. What happens is this page does a search and brings up a table based on the search. Each table item can have a checkbox, which allows the user to delete or modify it. If the user goes to that page, they need to select at least one item.
The tricky part is, since the number of checkboxes can vary Im unsure how to validate one is checked.
Here is what I tried so far, but no luck at all. Maybe someone can point me in the right direction with this?

<script type="text/javascript">
function ValidateForm(){
var msg='';
if(document.getElementById('CC').value==''){
msg+='- Please enter CC
'; .....

I am having some trouble with my javascript doing what I want it to, which is returning values (true/false || 1/0).I haven't used much javasript but I am experienced with C#, Java, Python etc so this is sort of new to me syntax wise.Here is what I have so far:http://jsfiddle.net/HpSyJ/1/note: for some reason css doesn't like jsfiddle :S, the error messages are hidden in my Notepad++ & firefox combo thoughReally all I want is when I hit submit, it runs an alert or changes the error message to visible.

I have a form with an e-mail, password and confirm password field. I also have two Javascript scripts, one for the e-mail field and one for the password and confirm password field. They seem to work together. But when I fill in an invalid e-mail address and a valid password, Javascript forgets to check if the e-mail address is valid and sends the form.How can I let both Javascript scripts work better together? Or does someone know how to merge these two scripts?Below the whole code:
Code JavaScript:
// E-mail validation
function validate_required(field,alerttext)
[code]....

In the following HTML code, when I change the value of one text field
then click "Modify" button, if the validation fails a message will
popup and the cotent of the form should NOT be submitted. (The actual
code connects to the database at the backend so I can check if the
value is submmited).
It works well in IE6.0 and Netscape 4.75.
But in Netscape 7.1, if the validation fails, the message pop up but
the form submit still go through. In another word, the return from JS
function inRangeInteger(), which is triggered by onChange event of the
text field, is ignored when the form submit. Code:

I'm using bassistance.de's form validation, as shown here: [URL] In the very possible event that someone is browsing without JavaScript enabled, I've put together a PHP form validation that should direct the user to an error page. The JavaScript works when I do not have the validation part in the PHP. When I do, it seems the JavaScript is completely ignored. Here's my HTML:

My JavaScript Form Validation doesn't work at all in Netscape, but it works fine in IE.
I made some of the suggested changes which enabled it to work in IE. I couldn't make all the changes because then it didn't work in IE.
How can I enable this javascipt form validation to work in Netscape? When I use netscape, none of the alert boxes appear. It submits the form without validating anything.
In IE, I get all the alert boxes and everything is validated.

Using JQuery validation plugin, it will work in css, class='required", but I use method to validate, it will not work. The coding is below. It will skip the validation and go to server.
function saveNew(){
$("#my_form").validate({
errorLabelContainer: $("#RegisterErrors"),
rules: {
scope: { required: true }
},
messages: {scope: "scope is required" }
});
$("#my_form").submit();
}
<div id="RegisterErrors" style="display:none" ></div>

[URL] I'd also like to use this plugin, so I don't have to create complex validation rules. validation plugin [URL]Trouble is, I can't figure out how to prevent form submission without first checking to see if the form is valid. My attempts so far have been based on using submit() to prevent submission of the form if validations valid() method returns false. But this doesn't seem to work. If I use ajaxForm, the submit() function seems to work differently. A form will still be submitted, despite a return false. validate has a valid() method that returns false if the form fails validation. How can I submit the form only if valid doesn't return false?

I currently have a form named "survey". I found here a JavaScript to validate my form.
I am having serious issues with this script, either it won't execute at all (the form doesn't work, as well as the validation) or the form submits without validating the form.
Here is the current JavaScript I am using.

I have a form with multiple fieldsets which are visible conditionally. There are three submit buttons "Abandon", "Save" and "Save & Continue". Each button should validate specific controls of the form and submit it. I tried setting "onsubmit: false" and checking for "$('#myForm').valid ()" on click of these buttons., but that validates all controls of the form.

I have a formdivided into 2 fieldsets (see the image) : MASTER and DETAIL. When I press Add in the DETAIL fieldset a new item is added to an array where I store temporarly the data entered trough the DETAIL inputs and finally when I press save I send both the MASTER and DETAIL (the temporary array shown in the html table) data to the server. As you may have already noticed, I need to validate both MASTER an DETAIL, but I don't want the Save button to fire the DETAIL validation or the Add link to fire the MASTER validation. I've been googling for a while and though I couldn't find exactly what I've been looking for, I found that it's possible to add/remove a class (e.g, required, number); that gave me some ideas on how to simulate validation groups and here's the code:
<script>
$
(
document
[Code]...
Although this code allow me to stop the MASTER validation from firing when I press Add( and DETAIL validation when I click Save), I still can't manage to insert a new DETAIL if only if all of the inputs in the DETAIL fieldset are valid and, what's more I don't want the Add link to cause a form submission.
