How to control order of frames loading?

CharlesEF · Jan 11, 2010

Hi All,

I have an HTA with 3 frames. In the main frameset HTML, the very
first frameset, I have an onload function. This frameset function
MUST execute before any of the 3 frames are loaded because it sets
global variables to be used among the 3 frames.

During all my tests it seems that the frame page is loaded before the
frameset onload function has executed.

Is there any way to insure that the frameset onload function has
completed before the frame pages are loaded?

Thanks for any help,

Charles

As in ` said:

global variables to be used among the 3 frames.

Unless you mean "initialize" or "modify" by "set", a function can _not_
"set" global variables. It could set (add/modify) globally available
properties, if that; but you really want to declare your variables in the
global execution context.

During all my tests it seems that the frame page is loaded before the
frameset onload function has executed.

No, for it is specified that a `load' listener of an element is called
*after* all its sub-items have been loaded (whereas there is uncertainty
what "loaded" means in this context).Â¹

However, as the HTML 4.01 Frameset DTD allows a HEAD elementÂ², you could,
if your variable initialization would not rely on the DOM too much (which
tends to works asynchronously) or at all, use a SCRIPT element to
*actually* declare global variables.

....
<head>
...

<script type="text/javascript">
var answer = 42;
</script>
</head>

<frameset ...>
...
</frameset>

Hi All,

No need to help with this problem. I was over thinking the problem.
There is no need to control the order the frames load. After giving
up for the night I posted this plea for help and watched a DVD. After
the movie was over the solution hit me, turns out to be very simple
fix. I removed the onload function call from the frameset and move
the function call to a script block. This way the global variables
are set before the frameset even loads.

Thanks for looking,

Charles

Hi PointedEars,

I did not see this message when I just posted my solution to my
problem. I already did what you suggest and it works great.

Thanks for the help,

Charles
