  • Loop Syntax in jQuery

    Posted by Sourabh on April 13, 2016 at 8:17 am

    jQuery 3.0 is the most newest version of jQuery. There are many changes in it, but one of the important change
    is the syntax of loop using for..of loop.

    For example earlier we use the syntax shown below:-

    var $divelements = $("div");
    for (var x=0; x< $divelements.length; x++){
    $divelements[x].addClass("dummy");
    }

    Here's the new syntax:-

    var $divelements = $("div");
    var i = 0;
    for(var elm of $divelements) {
    elm.addClass("dummy");
    }

    With the help of this new syntax, you will get DOM elements, instead of jQuery collection. You not need to use index to get element, it will be directly accessible to you.

    You can also do the same as below :-

    $("div").each(function(index) {
    $(this).addClass("dummy");
    });
