We can break both a $(selector).each() loop and a $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

return false; // this is equivalent of 'break' for jQuery loop

return;       // this is equivalent of 'continue' for jQuery loop

Note that $(selector).each() and $.each() are different functions.

Although true, this doesn't seem to be documented. Is this an 'unofficial' feature? – Michael Scheper Oct 12 '16 at 18:17

It is documented here http://api.jquery.com/jquery.each/ @MichaelScheper – Jayram Oct 13 '16 at 05:09

That's the first place I looked, of course. I see it now; it kinda gets lost amongst all the examples. – Michael Scheper Oct 13 '16 at 17:28

$('.submit').filter(':checked').each(function() {
    //This is same as 'continue'
    if(something){
        return true;
    }
    //This is same as 'break'
    if(something){
        return false;
    }
});

While this code may answer the question, providing additional context regarding why and/or how this code answers the question improves its long-term value. – Ajean May 12 '16 at 16:08

return or return false are not the same as continue. If the loop is inside a function the remainder of the function will not execute as you would expect with a true "continue".
