Sort HTML list with HTML content using JQuery

Question

Is it possible to sort the list bellow from the lower number to the bigger number, keeping each li content?

    

        39
        <         


        

Answer 1

Your function should be like this.

function numOrdDesc(a, b) {
    var aTxt = parseInt($(a)[0].innerText, 10);
    var bTxt = parseInt($(b)[0].innerText, 10);
    return (bTxt - aTxt);
}

Answer 2

Try below code,

$(function() {
    $('button').click(function() {
        var liContents = [];
        $('ul li').each(function() {
            liContents.push($(this).html());
        });
        liContents.sort(liSorter);
        $('ul li').each(function() {
            $(this).html(liContents.pop());
        });
    });
});

/*
  Below function is kind of a workaround for the listed HTMl
  you need to update it if you have proper HTML.
*/
function liSorter(a, b) {
    return (parseInt(b) - parseInt(a));
}

Edit: Updated your markup a little for a better code,

1. Wrapped those number with span tags like <span class="num">39</span>
2. Updated sorter function as below,

Code:

function numOrdDesc(a, b) {
    var aTxt = parseInt($(a).find('.num').text(), 10);
    var bTxt = parseInt($(b).find('.num').text(), 10);
    return (bTxt - aTxt);
}
