detecting submit control in Javascript

[wardy]

Hi all,

Looking for a bit of help with this one...I have a situation where I
need to be able to determine the control that initiated a form's submit
action in client-side Javascript. I am currently calling a Javascript
function on the client-click that returns true/false to control the
submission of a product, but I am now trying to implement functionality
to disable the buttons after the initial click, but continue with the
submit operations. My form is a mixture of HTML and .NET controls, so
I'm wondering if there is a generic way to determine in Javascript what
control actually caused my validation function to be invoked, short of
having to pass the control as part of the argument list - I am trying
to get a generic solution not requiring that level of modification.

Of note here is that as soon as I disable a button, the postback event
doesn't fire anymore, so I'm having to manually invoke this postback in
Javascript, and this is why I need the control that initiated the
submit, as I must invoke it's postback routine.

Thanks,

wardy

Hi ASM,

Thanks for the reply....is there not any way to determine the
submission control without having to put the value attribute on the
controls? I was hoping for a manner that would not require any
additional coding to get this, simply due to the dynamic nature of my
application.

Thanks,
