如何将表td数据转换为特定行的JSON？

Question

嗨，我有动态数据，如果是的话我会生成HTML表格。现在我想分别提交每一行。但我无法从每一列获取数据。请指导。这是我的表结构：

<table id="tblQuizzes" class="table table-striped">
<thead>
    <tr>

        <th>Student Name</th>
        <th>AGN Test 1</th>
        <th>Assignment</th>
        <th>Food Chef</th>
    </tr>
</thead>
<tbody>
    <tr id="tr_1">
        <td>
            Studet 1


        </td>
        <td>
            <input name="Id_1_2" value="29" form="form1" type="hidden">
            <input class="Id" style="width:30px;" value="9.00" name="1_2" form="form1">
            /10.00                                                <input name="OldValue_1_2" value="9.00" form="form1" type="hidden">



        </td>
        <td>

我想要这样的数据：

    [
{
id: 1,
newValue:"assignment",
oldValue:5,
},
{
id: 2,
newValue:"assignment",
oldValue:5,
},
{
id: 3,
newValue:"assignment",
oldValue:5,
}
]

这里的HiddenField1在TD == Id，第二个输入文本框是newValue，第三个hiddenfild是＆＃34; oldValue＆＃34;
