How would I disable a button?

I have a series of radio boxes on a php page. Depending on some conditions, I'm disabling them or enabling. With this, a situation may arise where all the radio boxes are disabled. How would I disable the submit button when all the radio buttons are disabled?

Set the disabled attribute on the submit button.

No, i mean how would i check if all the radio boxes are disabled? If one or two are disabled, I don't want to disable the submit button...

PHP has no control over this stuff. Moved to Client Side.

Got it!

Code: Select all

<script language="javascript">
window.onload = function(){
	var count1;
	count1 = 0;
	for(i=0;i<document.course.course_id.length;i++) {
		if(document.course.course_id[i].disabled == true)
			count1++;
	}
	if(count1 == document.course.course_id.length)
		document.course.course.disabled=true;

}
</script>
Thank You :)
