Question

我遇到Draggable和Droppable的问题，我尝试了很多代码，但似乎事件没有起火，

任何人在这里帮助我，请帮助我，我使用JSON数据文件来显示数据，我正在获取html页面上的所有数据，但只是拖放问题，我正在使用netbeans和Chrome浏览器（我没有广告拦截器）。

    <link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css">
    <script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>

    <style>
        table {
            border-collapse:collapse;
        }
        table tr td {
            border: 1px solid red;
            padding:2px 15px 2px 15px;
            width:auto;
        }
        #tabs ul li.drophover {
            color:green;
        }

    </style>
    <script>
    $(document).ready(function () {

        $("tr").draggable({
            helper: "clone"
        });

        $("tr").droppable({
            drop: function (event, ui) {


                $(ui.draggable).remove();
                $(ui.helper).remove();

在ajax成功函数中使用可拖动代码而不是DOM准备好：

success: function (data) {
//other code
  $("tr").draggable({
            helper: "clone"
        });

    $("tr").droppable({
        drop: function (event, ui) {


            $(ui.draggable).remove();
            $(ui.helper).remove();
        }
};

Draggable＆amp; amp;可弃
