我正在测试网站的安全性，并尝试利用其XSS，我使用了<script>标记。但是，此网站对输入有字数限制，因此我的结束脚本标记未插入数据库中。现在，当我打开网页时，提交按钮不再出现，因为它位于截断的脚本标记内。由于Chrome的自动更正，该特定脚本标记会在提交按钮标记后关闭。有人能帮帮我吗？
自动更正后，页面的HTML代码如下所示。

使用Chrome，您可以右键单击最后一个可见元素或页面上的其他位置，选择Inspect，然后使用Chrome内置的开发人员工具编辑浏览器中加载的HTML。例如。删除/更改<script>标记。并查看该页面是否再次可用。
您还可以尝试最新版本的Firefox或MSIE，它们具有与上述非常相似的功能。
