如何按字母顺序排序JQuery UI可排序？

Question

我想知道是否有可能将JQuery UI可排序的默认值按字母顺序排序.如果是这样,如果我将项目添加到可排序项中,是否也可以按字母顺序对其进行实时排序？以下是我的代码:

// Adds item to sortable list
$(".addButton").click(function(e) {
    e.preventDefault();
    // set var item to be the string inputted by the user
    var item = $("input[name='brewItem']").val();
    // parses input string, splitting at commas into liArray containing substrings as elements
    var liArray = item.split(", ");
    // for loop to add each brew to the sortable list (length-1 because last element in array is empty string)
    for (var i = 0; i < liArray.length-1; i++) {
        // sets var $li to the string in the ith index of liArray
        var $li = $("<li class='ui-state-default'/>").text(liArray[i]);



        // adds var $li to gui
        $("#sortable").append($li);
    };
    // refreshes the page so var $li shows up
    $("#sortable").sortable("refresh");
});

我不太确定在何处或如何实现这一点.任何帮助表示赞赏,谢谢!

You need to tweak it to make it sort as you need.

Try this:- Fiddle

Use custom sort method

 function sort() {
    var sortableList = $('#sortable');
    var listitems = $('li', sortableList);

    listitems.sort(function (a, b) {

        return ($(a).text().toUpperCase() > $(b).text().toUpperCase())  ? 1 : -1;
    });
    sortableList.append(listitems);

}

Call it in your sortable's create event Create and in Button Click

$("#sortable").sortable({
    create: function (event, ui) {
        sort();
    }
});

Or Extend jquery ui sortable widget to include your custom sorting logic.
