Nested jQuery.each() - continue/break

Question

Consider the following code:

    var sentences = [
        \'Lorem ipsum dolor sit amet, consectetur adipiscing elit.\',
        \'Vivamus aliquet nisl quis          


        

Answer 1

I've used a "breakout" pattern for this:

$(sentences).each(function() {
    var breakout;
    var s = this;
    alert(s);
    $(words).each(function(i) {
        if (s.indexOf(this) > -1)
        {
            alert('found ' + this);
            return breakout = false;
        }
    });
    return breakout;
});

This works nicely to any nesting depth. breakout is a simple flag. It will stay undefined unless and until you set it to false (as I do in my return statement as illustrated above). All you have to do is:

1. declare it in your outermost closure: var breakout;
2. add it to your return false statement(s): return breakout = false
3. return breakout in your outer closure(s).

Not too inelegant, right? ...works for me anyway.
