<sx:submit targets="div2";/>在 struts 2 中不起作用 [英] <sx:submit targets="div2" /> is not working in struts 2
问题描述
我正在使用 struts 2 框架开发 ajax.应用程序有两个文本框姓名"和年龄".在提交时，这两个值应该使用同一页面上的 div 标签更新.
I am working on ajax using struts 2 frame work. Application has two text boxes "name" and "age". On submitting , those two values should be updated using div tag on the same page itself.
<sx:div id="div2" executeScripts="true" theme="ajax">Value</sx:div>
<sx:submit targets="div2" value="submit">
当我在 sx:submit 中使用targets"属性时，出现一些异常.当我删除目标"时，没有抛出异常.但是应用程序需要目标"属性来更新 div 标签.我需要处理异常吗?我正在尝试将此作为示例，我的应用程序需要这种功能.帮我.
when i use "targets" attribute in sx:submit ,getting some exception. when i remove "targets" no exception has been thrown.But application needs "targets" attribute to update the div tag.Do i need to any handle exception ? I am trying this as a sample exmple , my application needs this kind of functionality. Help me.

<s:textfield name="name" label="Name"></s:textfield>
<s:textfield name="age" label="Age"></s:textfield>
<sx:submit value="submit" targets="div2"> </sx:submit>
