Andy's solution made me want to ask this question which still confuses me for some reason.
I understand that when using return in a function, you can return a value. I can do
return x;
and return x to the caller of the function.
But how does return function otherwise? Andy used:
function checkSize() {
var fs = document.getElementById("yourFrameset");
var fsRows = fs.rows.split(",");
if (fsRows[2] == 0) {
return;
}
if (fsRows[1] > 335) {
fs.rows = "25,335,*";
}
}
I assume the return; here exits you out of the script - is this correct? I've never quite
understood the concept - return by itself also assumes "return true"..is this correct? I've looked
it up on the web dozens of times yet still am not straight on it.
