jquery: reverse an order

Question

How can I reverse an order with jquery?

I tried with the suggestion like this but it won't work!

$($(".block-item").get().reverse()).each(function() { /* ... */ });

Have a look here.

I want the boxed to be rearranged like this,

18
17
16
etc

Thanks.

Answer 1

If you have a container around the list, it's a little easier:

$("#container").append($(".block-item").get().reverse());

You can use this:

$($(".block-item").get().reverse()).each(function (i) {
    $(this).text(++i);
});

Demo here.
Second demo here (changing the DOM elements positioning).

Another way, using also jQuery with reverse is:

$.fn.reverse = [].reverse;
$(".block-item").reverse().each(function (i) {
    $(this).text(++i);
});

One more alternative is to use the length (count of elements matching that selector) and go down from there using the index of each iteration. Then you can use this:

var nr_of_divs = $(".block-item").length;
$(".block-item").each(function (i) {
    $(this).text(nr_of_divs - i);
});

One more, kind of related to the one above:

var nr_of_divs = $(".block-item").length;
$(".block-item").text(function (i) {
    return nr_of_divs - i;
});

Answer 3

Your code is working. Just choose jQuery framework on the left hand.

 $($(".block-item").get().reverse()).each(function() {
     $(this).appendTo($(this).parent());
 });

Answer 5

try this:

function disp(divs) {
      var a = [];
      for (var i = 0; i < divs.length; i++) {
        a.push(divs[i].innerHTML);
      }
    alert(a);
    }

    disp( $("div.block-item").get().reverse() );
