.net - identify whether a button has a class when clicked

I have an asp button which I am using in 2 different places (appending to a new pla开发者_如何学Goce and adding a class using jquery under certain conditions).

I need to slightly alter the function that runs when this button is clicked depending on whether or not this button has a given class. Is this possible??

So something like this...

if myASPButton hasclass("xyz") then
...
end if

i'm using vb.net for what it's worth.

It's not possible, clicking a button causes a postback, the only information posted back is form data. Modifications to the HTML client-side wont be reflected severside.

You will need to make a hidden field and populate the value of the hidden field and use that for checking severside.
