Global Variable Question

[Chris747]

Howdy Folks,
Is there a method to check for the existence of a global variable before attempting to "getGlobalVariable" ?
If i attempt to get it before it's been set, i get "GlobalVar" has no properties, which is to be expected, but it cause an error in the script and i'm looking for a work around. Perhaps some way to declare it that I'm not using ?

Thx,
Chris

Hello Chris,

What you need to do is add a null check after you make the request. If the global variable does not exist, getGlobalValue() will return null. Try the following.

var myVal = getGlobalValue("varName");
if (myVal == null) return;

Thx Jason..... works great ! I hadn't realised that it would return null if not found.
