Prevent browser stall warning

Copy linkTweet thisAlerts:
Nov 27.2008

I have a computational application in JavaScript that has 0.01% chance of causing the browser to give user a script stalling warning.

Assume the script continues without the warning, it would finish in under 5 seconds. I was wondering if anyone know how to prevent that warning from ever popping up.

@MrNobodyNov 28.2008 — You can prevent it by scheduling your computations in sections. The first section starts the next section as a separate function on a timer:
[CODE]function firstPart()
{
...etc...
window.setTimeout("secondPart()", 100);
}[/CODE]
Then, that second function can start the next section as a separate function on a timer:
[CODE]function secondPart()
{
...etc...
window.setTimeout("thirdPart()", 100);
}[/CODE]
The last function, in the series, outputs the results of the computations and then just ends:
[CODE]function thirdPart()
{
...etc...
return;
}[/CODE]
The little releases between functions helps the browser to have a chance to breath.

@scragarNov 28.2008 — The warning is there to stop excessive ram or CPU usage, if you can break that usage up it can prevent the warning, either rewrite your code to reduce load, or add break points in the code where you can do something like:
function intensiveBit1(){
// some stuff here
setTimeout(intensiveBit2, 500);// wait half a sec
}
function intensiveBit2(){
// then some more stuff
setTimeout(intensiveBit3, 500);// wait half a sec
}
function intensiveBit3(){
// last bits of your function or whatever
}

Success!
