Enable/Disable Question

BKer · Apr 17, 2001

I am trying to enable a disabled list box when the user clicks on a radio button. I am new to javascript and am not sure if the simple function is correct and if I am calling it right. Any help would be appreeciated.

<form name=form1 method=post action=test.asp>
<head>
<script language="javascript">
function enable(){
document.form1.cbosecondary.enabled = "true";
return;
}
</script>
</head>

<form name=form1 method=post action=test.asp>
<p><font size=5>Aging Work Order Form</font><br><br>

<p>Search By</p>
<input type=radio name=shop value="ftr_description" checked >Entire Shop
<input type=radio name=shop value="sh_name" onclick="form1.enable();">One Trade<br>
<P>Sort By</P>
<input type=radio name=sort value="wo_request_date" checked>Date
<input type=radio name=sort value="wo_number">Work Order #<br>
</form>

The first problem is that "document.fomr1.cbosecondary" doesn't exist in the document (at least not what you posted) so you will get an "object expected" error on that.

You do not need to attach the enable() function to an object (you may get errors from this anyway). But since you have specified that exactly one action needs to be taken when the user clicks, so you can put: onclick="enable();" in that radio button tag.

Is this helpful?

And if you do want to enable the box the way you had originally posted, don't enclose the word, true, in quotation marks --

it's a boolean condition, not a string literal.

Ok this is the rest of the code appended with your advice. It gives me an object expected error. Your suggestion makes sense, but I am still confused. Thanks for your help.
