没有显示问题，但不起作用-dwr

1.检查DWR路径

如果您要在WEB-INF中包含查看文件，则

<script src='dwr/engine.js'></script>         <script src='dwr/util.js'></script>         <script src='dwr/interface/TempCardServlet.js'></script>

引用此方式将起作用。如果不是这样，则必须给出如下所示的正确路径

<script src='../dwr/engine.js'></script> <script src='../dwr/util.js'></script> <script src='../dwr/interface/TempCardServlet.js'></script>
