Topic awaiting preservation: Blocking script execution

I am trying to implement the following behavior:

while (something) {
openSomething();
waitUntilThatSomethingIsClosed();
nextSomething();
}

I tried using setTimeout to see if I could pause the execution for a set period of time as a test, however the loop execution continued anyway. Any one have any suggestions?

var howManySeconds = 2;

function pause() {
myTimer=setTimeout("whatToDo()",howManySeconds*1000)
}

function whatToDo() {
window.location="http://www.gurusnetwork.com/";
}

is how I pause doing something (in this case, going to another page).

Dunno if this helps. I suspect not.

Not exactly, but I'm always looking to learn something new.

I'm basically looking for sleep()/notify() behavior.

I actually have a script where stopping an entire script dead in its tracks at a certain point would be quite handy. But I dont think you can do that , have and if(stopped) on key functions and then set notstopped to true to stop it doing anything. ( you'll have to stick in var stopped = 0; globally, of course ) Pugzly's trick works on setInterval aswell.

You can do this with a setTimeout loop something like so

// These has to be set here once since JS breaks if
// you try to run a conditional test on a un intialized variable.
var timer = false;
var flag = false;

//you can make your interval whatever it's in ms
interval = 1000

function sleep() {
if (flag) {
clearTimeout(timer);
nextSomething();
} else {
timer = setTimeout('sleep()', interval);
}
}

Now you can either set flag to true somewhere or stick someother test in there to see if that something is closed or whatever. This should kinda replicate perl's sleep function

Thanks guys for the suggestions. I'll have to play around with them this weekend.
I'll let you know how it works out.

meccaman

sleep() or alike does not exist in JavaScript!

what you can do is write a loop that makes some processing just to consume the desired delay of time.

I got the functionality I'm looking for.

The logic goes something like this:

var globalArray;

doSomething(arr) {
if (arr) {
// Do the something

return;
}
// Otherwise, do nothing.
}

// This is called by an event in the something
handleUserEvent() {
doSomething(globalArray.pop());
}

To start things off I call doSomthing(globalArray.pop()), the param is an ID which is used to grab and show a record from the database. The user can view/manipulate the record and close the display generating an event that calls handleUserEvent. handleUserEvent calls doSomething and the process continues until the array is null.

Anyway, it works for what I'm trying to do. Thanks for all the inputs.
