用jQuery实现复选框ID获取，

HTML部分：

<table id="carouselInfoListTab"
       class="table table-bordered text-center table-striped table-hover table-th-nowrap mt20 table-td-m"
       xmlns:th="http://www.w3.org/1999/xhtml">
    <thead>
    <tr class="active">
        <th>选择</th>
        <th>展示顺序</th>
        <th>商品标识</th>
        <th>商品名称</th>
        <th>商品描述</th>
        <th>默认图片链接</th>
        <th>开始时间</th>
        <th>结束时间</th>
        <th>活动标识</th>
        <th width="100">操作</th>
    </tr>
    </thead>
    <tbody>
    <tr th:if="${#lists.isEmpty(goodsList)}">
        <td colspan="15">没有数据</td>
    </tr>

    <tr th:unless="${#lists.isEmpty(goodsList.result)}" id="proNmSelectList" th:each="map,indexInc:${goodsList.result}">
