js实现table中获取不同td的值，并且md5加密，匹配md5的值（避免通过查看网页源代码可以看到正确答案），再用js前端判断输入与正确的值是否相同。最后再把错误的单词计数，并且输出，后端加入对应错误的数据库表中。

html代码片段：

<div class="col-md-11">

                <table class="table table-common table-bordered">

                     <tr>

                        <th>序号</th>

                        <th colspan="2">中文</th>

                        <th colspan="2">英文</th>

                        <th>序号</th>

                        <th colspan="2">中文</th>

                        <th colspan="2">英文</th>

                     </tr>

                     <tbody class="tbody" name="Tbody1" id="tbody1">
