Frames
can actually help JavaScript too!
With JavaScript helping others all the time, its nice to know that
someone gives it a hand once in a while too. Frames can be very helpful to JavaScript when
creating JavaScript driven applications, and the reason requires a little explanation.
By default, all variables and functions created in
JavaScript in one page is lost when you leave that particular page. For example, if I make
a declaration in this page:
var x=500, this x only exists in this page-as soon as you leave, x is erased, gone. This
is great, in most cases, since if the browser retains every variable, not only will it
overload your memory, but also, if two pages use the same variable, there will be a small
riot starting in your browser. Having said that, in special cases, what if you want
to retain that variable temporarily, even if a new page is loaded? Well, the key is by
using frames. You can store all variables you want to retain for further processing in one
frame that is not being changed,while the other frames can change all they want. Since
that particular frame is not being loaded with new content, the variable is retained,
until you leave that whole document, of course.
