multi-submit button: identify which submit button clicked

[webster5u]

Hi, i have a question about JavaScript. When we click a submit button from the form with multi-submit button. Can JavaScript detect which submit button has been submit?

I make a form with 3 submit button (select, update and delete) and i put validation javascript function in onSubmit event handler. May i apply different validation according to different submit button?

Sure, you can do that... You can have different validate function and onlick of the submit button u can validate form variables...

form variable? Can you explain how it work?
if we take the code below as example, then what's variable name in Javascript.

<form action="..." method="..." onSubmit="validatetion(this)">

<input ...
<input type="submit" value="search" name="srh">
<input type="submit" value="update" name="up">
<input type="submit" value="delete" name="del">
</form>

He was referring to adding an onclick to the submit buttons:

<input type="submit" value="search" name="srh" onclick=" return validateSearch()">
<input type="submit" value="update" name="up" onclick="return validateUpdate()">
<input type="submit" value="delete" name="del" onclick="validateDelete()">

Another option is to set a variable to the name of the button onclick and check for it within the validation function.
