Javascript 表行拖放，获取ID和序列

我正在使用这个插件：

如果我拖放一行，我会在alert中获得被删除的行ID，它会工作

如何获取行序列？我想使用它，用ajax更新图像序列

$("#table-2").tableDnD({
    onDrop: function(table, row) {
        var rows = table.tBodies[0].rows;
        var debugStr = "Row dropped was ID: "+row.id+"";
        alert(debugStr);
    }
});

我从我的网站soruce复制表源代码，表是由php生成的

<table class="table table-hover table-bordered list" id="table-2">
    <thead>
        <tr>
            <td style="width: 1px; text-align: center;"><input class="checkAllCheckboxes" type="checkbox"></td>
            <td style="text-align: center;">ID</td>

这就是你需要的

试试这个

$("#table-2").tableDnD(
{
    onDrop: function(table, row) 
    {
        var rows = table.tBodies[0].rows;

        alert("Index: " + $(row).index());

        var debugStr = "Row dropped was ID: "+row.id+"";
        alert(debugStr);
    }
});
