Variable scope in lambda

[JamesB]

In this thread http://w3schools.invisionzone.com/index.php?showtopic=51196 in the link he gave: http://jsfiddle.net/96eLrn6e/

 

He defines 2 local variables in a lambda, but then uses one of those variables outside the lambda, why does that work?

 

I was thinking that the local variables in the lambda would be destroyed when the lambda finishes executing.

It's not using the variables defined in the onload handler, it's probably using a "feature" where the browser will use document names and IDs as global variables for those elements. It shouldn't be counted on, you should use getElementById instead.

Ah thanks! had a feeling it was that.
