How to Jquery each complete

The promise() method is usually for AJAX, but it can be used with each() to achieve what you want:

$('.element').each(function (key, val) {
    console.log('Do something to each individual .element');
}).promise().done(function () { 
    console.log('Did things to every .element, all done.');
});

To execute code after the each loop is over :

var count = $("element").length;

$("element").each(function (i) {
    // loop
    if (i+1 === count) {
        // this will be executed at the end of the loop
    }
});
