Solution to js pop-up box error returned by struts json type exception

When the struts framework is configured with an exception, for example:

<package name="sysCnn" namespace="/" extends="json-default">     <global-results>       <result name="error">/WEB-INF/pages/error.jsp</result>       <result name="over">/js/over.js</result>     </global-results>          <global-exception-mappings>       <exception-mapping result="error" exception="java.lang.Exception" />       <exception-mapping result="over" exception="com.xxx.exception.OverException" />     </global-exception-mappings>     <action name="ConnONGL_*" class="com.xxx.action.LoginAction" method="{1}">       <result name="success" type="json" >           <param name="root">jsonMap</param>       </result>   </action>  

When an action throws an exception, the ideal situation is to go to the exception information page or the js pop-up prompt, the error message page or pop-up prompt is displayed only on the console of the browser.

Modify the ajax request and comment out dataType: "Json". The js pop-up box will be displayed normally.

$. Ajax ({url: $. contextPath + "/ConnONGL_login", // dataType: "Json", comment out async: false, cache: false, data :{
