Javascript列表框人口不起作用

Question

如果重要的话，它需要在IE中工作。这应该基于列表框中的选择来填充表格单元格。稍后，我会将照片更改为将照片添加到框中的HTML。

HTML：

<script src="garver_contact.js" type="text/javascript"></script>
<table class="table table-bordered table-striped">
    <tr>
        <th>
            <select class="col1 selectTopic">
                <option>Payroll</option>
                <option>Tax</option>
                <option>Accounts Payable</option>
            </select>
        </th>
    </tr>
    <tr>
        <td class="col1 name"></td>
    </tr>
    <tr>
        <td class="col1 photo"></td>
    </tr>
      <tr>
        <td class="col1 email"></td>
    </tr>
      <tr>
        <td class="col1 phone"></td>
    </tr>
</table>
<script src="contact.js" type="text/javascript"></script>

使用Javascript：

data = {
    "contacts":
{
    "contact": [
{
    "name": "Payroll",
    "photo": "Emp 1 Photo",
    "email": "emp1@gusa.com",
    "phone": "4113834848"
},
{
    "name": "Tax",
    "photo": "Emp 2 Photo",
    "email": "emp2@usa.com",
    "phone": "4113834848"
},
{
    "name": "Accounts Payable",
    "photo": "Emp 3 Photo",
    "email": "emp3@usa.com",
    "phone": "4113834848"
},
    ]
}
}

$(".selectTopic").change(function () {
    var jthis = $(this);
    var whichCol;
    if (jthis.hasClass("col1")) {
        whichCol = "col1";
    }
    $.each(data.contacts.contact, function (i, v) {
        if (v.name == jthis.val()) {
            $("td." + whichCol + ".name").html(v.name);
            $("td." + whichCol + ".photo").html(v.photo);
            $("td." + whichCol + ".email").html(v.email);
            $("td." + whichCol + ".phone").html(v.phone);
            return;
        }
    });
});
