Optimize Pages Containing Numerous JavaScript Functions
by DevX Pro
I have produced a bunch of DHTML library functions that work in a cross-platform environment, down to the point of redefining the layer object in Netscape and writing customized event handlers. Now that I can do virtually anything I want with layers, the sheer amount of code this requires is making my pages amazingly heavy (for example, something that should be about 30 KB has now blown up to about 80 KB). How can I optimize my code so that I can get my page sizes down to a reasonable amount?
Track Changes on a Form
by DevX Pro
I have an HTML page that is broken up into two different frames. The left frame acts as a navigation tool. The right frame is the user interface, which consists of a form with different input types. I want to track when a field has changed so I can prompt users if they try to navigate away from this page using the left frame. I can track the changes by using an onchange event, but I can't seem to trap when they leave the page. I have tried the using the onblur for the page and the window, but I can't seem to get it right.
