Hi Everyone,

I have two drop boxes in my JSP. When i choose "Yes" in the first drop down, the second drop down should get disabled. When i select "No" then the second drop down should get enabled. I have used struts tag.

How do i implement this?



Thanks

disabled does not have a value, it is just disabled and it takes a Boolean not a string when setting it with JavaScript.

Exactly what I said, disabled does not have a value [attributes].

Hey Eric,

Thanks for your help. I tried setting disabled to false. But it is still not working.

I think there is some problem with this line : var DD2 = document.getElementsByProperty("POTX"); alert(DD2);
because i am not getting alert message for DD2.

Since i am using struts tag, i cannot use ID attribute with <html:select>. I have to use property attribute <html:select property="" >.

So what do i do now. javascript:emoticon('');

function DisableTR(value)
{
alert("hi");
alert(value);
var DD2 = document.getElementsByProperty("POTX");
alert(DD2);
if(value == "No")
{
DD2.disabled = false;
}
}

Thanks
