Form validation - prevent certain buttons firing

I have a general form validation question. I know very little about
javascript, a little more about PHP. Using yav (http://yav.sourceforge.net):

<form method="POST" name=edit onsubmit="retur n performCheck('e dit', rules,
'classic');" action="pages_e dit_submit.php" >
<input type="text" name="title">
<input type="submit" name="Save">
<input type="submit" name="Cancel">
</form>

.... PerformCheck fires when any submit button is click, which is logical but
I'd like to prevent this if it was the cancel button that was clicked (and
preserve form submission on pressing Enter whilst in the 'title' box.

Very many thanks

Nick

Declare another variable e.g. Var canc=false
In the onclick bit of the button you don't want to trigger the validation
routine insert "canc=true; "
In the onsubmit bit of <form> insert "return (performCheck() or canc);"

Apologies for holding you up, hope the solution helps someone in the future

If you don't want the 'cancel' button to submit, don't make it a
submit button. Presumably you want to run the validation but not
submit the form, so why not just use a plain button with a
appropriate label?

<input type="button" value="Check form" onclick="
performCheck('e dit', rules,'classic' );
">

I have a form on a webpage and want to use JavaScript validation for the form fields. I have searched the web for form validation scripts and have come up with scripts that only validate individual fields, such as an "Email Validation Script" or a "Phone Validation Script". Is it ok to put all these scripts on page as they are or should they be joined in some way together to be one script? I'm a total JavaScript newbie and am completely...

We have a site under development that uses validation web controls to validate the data entered in text boxes. But when the user changes his mind and presses cancel, or navigates using a hyperlink to another page, the validation controls activate because data has not been entered, and the user cannot cancel or navigate to another page. How do we allow the user to go to another page? Thanks

I was just dropped into someone else's code (isn't that always so fun?). I can't figure out why a custom validation control's server event function is executing. There is nothing (that I see) in page_load, or elsewhere, that says page.validate, no control says "causesvalidation=true", and the AutoEventWireup is set to false. So I would think that the control's server event function would NOT execute, but it does execute right after...

hi I m facing the following problem often : In a web page the user can click on 2 buttons "button1" and "button2". If the user clicked on button1 then I have to validate part of the form (some controls musn't be validated), and if the user clicked on button2 then I have to validate the other part of the form. Usually I would do this by using one custom validator (for all the web page) that detects the button that has been clicked and...

I have an application with a master form with a tab control containing nine tabs, each tab contains a subform. I have command buttons on my main form including: Save , Cancel , Close.

I need the 'Cancel' button to just undo any changes...

Hello guys, now that I'm that I'm working on my first major 'open' forms (with uncontrolled users I mean, not a secure backend-interface), I'd like to add a lot of possibilities to check wether certain fields match certain criteria, and inform the user in different ways when the data is wrong (offcourse, this will be checked on posting the data again, but that's something I've got a lot of experience with). Now, offcourse it's...

I have a form, Form6, that has a bunch of buttons overlaid on it.

So far, I've tried the below event handlers, and the only one that has worked is of course the named button event click, for a particular named button (button3...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
