to cancel mouseclick 1

[Rydel]

I have a submit button:

<input type=&quot;submit&quot; name=&quot;sub1&quot; onclick=&quot;checkIt()&quot;>

I'd like to cancel mouse click inside the function checkIt() in case some condition is true (e.g. some data is missing).

Thanks a lot in advance!

do you mean : you don't want the form to be submitted if there is an error ?
you don't need to cancle any click then !!!
just make your validation function return a boolean : true if everything went fine, false if some data is missing ...
another thing is : DO NOT call the function from the input type=submit !!! it won't work !!! this fires the function NOT when the form submits but when one clicks - this IS different (use it for display purpose for instance)
it has to be fired by onsubmit, in the FORM TAG :
<form .... onsubmit=&quot;javascript:return checkit()&quot;>

thank you very much, iza. onsubmit event is really more appropriate in my case. but still, just curious, how do you cancel a click event? ---

i don't think you can cancel the EVENT - but you can make the click to do nothig tho ;-)
for instance, say this function is fired with &quot;onclick&quot;
function foo() {
if (.... ) // something you want to check
do_something
}
so if the condition is FALSE, the function won't do anything : it's just like it'd never been called !
