Validator code problem.

[Assimalyst]

Hi,

I have a code that returns invalid if a dropdownlist is at index 0.

function clientValidateCboBx(source, args)
{
var dropdown = document.getElementById(source.controltovalidate);
if(dropdown.selectedIndex == 0)
{
args.IsValid = false;
}
else
{
args.IsValid = true;
}
}

As above it works fine, but I want it to only return invalid if the
control it's validating is enabled, if it's disabled it should always
be valid. I tried adding && dropdownlist.enabled == true to the if
statement, but then the validator always returns true even when the
selectedIndex == 0.

Any ideas on a solution?

Thanks

I don't see enough of your script to see what it is that you're passing
as a "source" argument. However, getElementById() method expects a
string argument, and like the name says an id.

For example:

<div id = "myId">...</div>

Then in your script:

var myDiv = document.getElementById("myId");

args.IsValid = !dropdown.enabled && dropdown.selectedIndex;

Typo? You know the pertinent property is called - disabled - and is true
when the control is disabled and false otherwise?

Yes, I invented the property "enabled", but the logic is sound:


args.IsValid = dropdown.disabled && dropdown.selectedIndex;

Almost:

args.IsValid = dropdown.disabled || dropdown.selectedIndex;
