How to search for an id


freelance84

Recommended Posts

Ok i know i must be something wrong here but i can't see it. I want to check if an id exists before carrying out an action. Here's my if statement:

 

    if (document.getElementById("hiddenValues"))

 

The script isn't working if the id isn't on the page.

 

I take it this isn't the correct way to determine if an element exists... what is?

 

(ie simply says "Object Required")
