我是ajax和jquery的新手,并试图在我的代码中放置一个ajax调用。但下面是我发出警报时收到的错误消息:
我想做什么: 单击“编辑gif”,打开一个只有一个Fancy文本框(Tinymce)的模态对话框。在文本框中编辑内容后,单击模态对话框中的“保存”按钮,启动ajax调用以将内容保存在数据库中。
发生了什么: 模态对话框打开正确,我能够看到正确填充ajax调用的“数据”部分(放置警报以确认)。我相信网址也是正确的。如果我在浏览器中键入url,则控件会根据web.xml(Servlet中的Sysout被打印)转到我的servlet。但不知何故,点击“保存”按钮后,ajax调用永远不会进入服务器。如果你们中的一个人可以帮助我,那将会非常棒,非常感激。我的JSP(复制我认为仅相关的内容):
