        </td>
    </tr>

</table>
</form>

当我尝试提交表单时， alert("test:" + $('#indexSummaryForm').serializeArray()); 返回空值。请检查并告知代码中有什么问题？

Answer 1

您没有ID 为 indexSummaryForm的表单

 $('[name=indexSummaryForm]') // Should work

否则，您可以将 id 添加到表单并使用id selector

Answer 2

这段代码

$('#indexSummaryForm').serializeArray())

正在请求ID ="indexSummaryForm" 的对象，您没有 ID 属性。
