what am I missing?

Hi,

I'm stumped as to why this simple javascript won't rewrite a select menu's options to set the first one to "selected".

var theElements = new Array();
theElements[0] = "filter_request_3";
theElements[1] = "filter_request_4";
theElements[2] = "filter_request_5";
theElements[3] = "filter_request_6";
theElements[4] = "local_base";

for (i=0;i<theElements.length;i++) {
document.getElementById(theElements[i]).options[0].selected = true;
}

Is there a syntax thing I'm missing regarding the getElementById() portion?

FWIW, the for loop works great, and traverses the array just fine. It's just the select menu option isn't ever changed.

Any ideas appreciated!

Glenn

Syntax?
document.getElementById(theElements[i])[0].selected = true;

Thanks for the response.

Everything I've seen indicates the syntax should be getElementById(#*$!x).options[0].selected.

I tried it your way just to be sure and it didn't work.

Thanks again,
Glenn

Yes, syntax looks fine. Don't know why I questioned that earlier. It must be something else ... are you certain you have id attributes set up for each of your select elements to correspond with the array you defined?

I'm an idiot. Everything works once I made sure there actually were id's for getElementById to interact with! D'oh!

The code only had names, and once I added the id's it all worked as expected.

Thanks,
Glenn
