Subject RE: how to disable submit button when click on checkbox

I misread your post.  If the checkboxes are in the same form, here is some
example javascript code in an HTML page (save it as "example.html", check
some boxes, then hit submit. Everything you need to know should be in it.
The rest is between you and JavaScript.

<html>
<head>
<title>title
</title>
</head>
<body>
<script language="javascript">
function traverse(frm) {
	var i = frm.length;
	alert("size: " + i + " elements");
	for ( j = 0 ;j < i ; j++ ) {
		if ( frm.elements[j].type ==  "checkbox" ) {
			alert( "Analyzing type " + frm.elements[j].type +
				", named " + frm.elements[j].name +
				", value " + frm.elements[j].value +
				", checked " + frm.elements[j].checked );
		}
	};
	return "david.html";
}
</script>
<form name="david" action="example.html" onSubmit="traverse(this)">
<input type="checkbox" name="id" value="1">1
<input type="checkbox" name="id" value="2">2
<input type="submit" name="submit" value="submit">
</form>
</body>
</html>

Thanks for the reply. Do you mean change it to
onclick="this.form.delete.disabled=true"?It's still not working. The
checkbox is not even checked when click on it.

If it is in the same " ... " form tag, try this javascript:
this.form.delete.disabled=true

Subject: how to disable submit button when click on checkbox


I have a question regarding checkbox, how can I disable a certain submit
button when click on a checkbox?
I tried the following but is not working:

onclick="document.formName.delete.disabled=true" />

Also, is there a way I can count how many checkbox are selected in my jsp
code?

Please kindly help me.
