Javascript For Loop Callback?

Trying to think in Javascript rather than jQuery, so I'm wondering if I'm doing this right. I want to have a callback when my loop is finished. Is this the proper way? for(var i =

Solution 1:

For clarity, you should go with @mu's answer, but if you really must include the callback within the for construct, you can use the comma operator*:

for(var i = 0;
    i < divs.length || function(){ /* call back */ }(), false;
    i++) {

/* do some stuff */ 

}

*As explained in this fascinating article.

Solution 2:

Why not say what you really mean and call the callback after the loop?

function thing_with_callback(divs, callback) {
    for(var i = 0; i < divs.length; i++) {
        /* do some stuff */ 
    }
    callback();
}

Solution 3:

It seems to me the question is about the execution order of javascript code. And the answers are:

Yes you can put the callback outside because javascript code is executed line by line. In case of asynchonous ajax calls there might be other things to consider.
