Is there an equivalent Javascript or Jquery sleep function?

Question

I want something like this in javascript.

for (i = 0; i < 10; i++) {
    alert(i);
    // now sleep 1 sec
    sleep(1000);
}

is there a built in Javascript or Jquery for this?

Thank you!

There's no such thing, directly. You would have to tell javascript to wake 'something' up after some time using setTimeout.

This 'something' would be the code that you plan to execute after the sleep, of course.

From an example I found on the internet:

function dothingswithsleep( part ) {
    if( part == 0 ) {
        alert( "before sleep" );
        setTimeout( function() { dothingswithsleep( 1 ); }, 1000 );
    } else if( part == 1 ) {
        alert( "after sleep" );
    }
}

But that's fragile design. You better rethink your business logic to really do something after a second: call a different function instead of using these contrived helper variables.
