Question

struts2+ajax 一直error，求解

jsp代码:$.ajax({
url: deleteAction,
type: 'POST',
dataType: 'string',
error: function(){alert('删除失败！');},
success: function(result){
deleteRow(tbs,deleteLine);
}
});
action代码:public String execute(){
jijinService.deleteGudongTuantiMingdan(actionType,bianHao);
HttpServletResponse response = ServletActionContext.getResponse();
try {
response.setContentType("text/html; charset=UTF-8");
response.getWriter().write("success!");
} catch (IOException e) {
e.printStackTrace();
}

return SUCCESS;
}
struts配置文件：<action name="gudongDelete" class="com.cn.DeleteAction">
<result name="success" type="null">
</result>
</action>
后台代码debug都通过了，就是到前台后，一直执行error的方法，求解！！！！
struts配置文件：<action name="gudongDelete" class="com.cn.DeleteAction">
<result name="success">
</result>
</action>

Answer 1

把Action里的 return SUCCESS; 改成 return null; 就行了。另外配置文件<result name="success" type="null">这个没有必要写了。
