How to sort a random div order in jQuery?

Question

On page load, I am randomizing the order of the children divs with this Code:

function reorder() {
   var grp = $(\"#team-posts\").children();
   var cnt = g         


        

Answer 1

Keep original copy like following before calling reorder() function and use that for reorder later.

var orig = $("#team-posts").children();

$("#undo").click(function() {
    orderPosts();
});

function orderPosts() {
   $("#team-posts").html( orig )  ;
}

Working demo

Full Code

var orig = $("#team-posts").children(); ///caching original

reorder();

$("#undo").click(function(e) {
    e.preventDefault();
    orderPosts();
});

function reorder() {
    var grp = $("#team-posts").children();
    var cnt = grp.length;

    var temp, x;
    for (var i = 0; i < cnt; i++) {
        temp = grp[i];
        x = Math.floor(Math.random() * cnt);
        grp[i] = grp[x];
        grp[x] = temp;
    }
    $(grp).remove();
    $("#team-posts").append($(grp));
}

function orderPosts() {
    // set original order
    $("#team-posts").html(orig);
}
