 html as in markup
 <tbody>
 <tr>
 <tr class="item">
 <td> 1 </td>
 <td> C001 </td>
 <td> 7/26/2013 12:00:00 AM </td>
 <td> 100.00 </td>
 <td class="Weight"> 5000.00 </td>
 <td> Hydrated Lime Powder </td>
 <td> Order Pending </td>

 </tr>
 </tbody>

我想将Kg添加到TotalWeight值。我的代码不起作用。它显示了价值 Quantity1为undefined。如何在jQuery中访问表？我忘了定义重量，但代码仍无效，我发布了html标记

Answer 1

$(document).ready(function () {
    $("tr.item").each(function () {
        var weight = $(this).find('td.Weight').text(); // you left out the quotes and the closing paran
        var unit = "Kg";
        $("#TotalWeight").text(weight + unit);
    });
});

你应该实际上计算Scala中的总和（它看起来你正在使用Scala）。此外，您的循环会在每个模型后关闭<table>标记，并且您的<tr>标记永远不会关闭。您还有一个ModelItem，可能与其他地方一样modelItem。

如何使用Jquery将数字与“Kg”连接起来。我想用单位“Kg”连接TotalWeight字段
