当您在sortable1和sortable2中添加元素时，我需要向服务器发送ajax post请求。怎么做？感谢。

Answer 1

尝试使用sortable1，然后将其重复为sortable2。

var length1 = $("ul#sortable1 > li").length;
$("#sortable1").bind("DOMSubtreeModified", function() {
    if ($("ul#sortable1 > li").length >= length1) {
        $.ajax({
            url: "some Url",
            data: {parameter values},
            success: function(data) {
            },
            dataType: "html",
            type: "POST",
            cache: false,
            error: function() {
                alert("Process Not Finished");
            }
        });
    }
});

Answer 2

您可以在sortable1和sortable2列表中更改序列进行ajax调用，如下所示。

$( "#sortable1, #sortable2" ).bind( "sortchange", function(event, ui) {
   $.ajax({
        url: "some Url",
        data: {parameter values},
        dataType: "json",
        type: "POST",
        success: function(data) {
        }.
        error: function() {
            alert("Process Not Finished");
        }
    });
});
