JavaScript " null " and "undefined"
JavaScript :
I need to check if every object is null or undefined - if neither, I must proceed with the validation. Else, Javascript throws ugly errors on the screen.
Check for null
if(object!=null) // the object isn't null.
Check for undefined
if(object) // the object is not 'undefined'

JavaScript DOM
I just discovered that JavaScript DOM does have some problems - I ran into problems doing the cross - browser testing. Apprarently, some part of the code didn't work in Netscape & Mozilla.
E.g; IE recognizes the parentElement keyword but Netscae wants parentNode.
I need to scrouge the net for a compatibility list.........
