struts2中jquery无刷新怎么接受后台boolean值

$.ajax( {
type:"POST",
url:"pageTest.action!abc",
data:"userName="+$("#userName").val()+"&passWord="
+ $("#passWord").val(),
success:function(msg) {

//alert(msg);

}
});

以这种格式向后台传输数据，action中如何传一个boolean值过来呢！
我在success中的操作是局部刷新的吗？

Answer 1

HttpServletResponse response = ServletActionContext.getResponse();
response.setContentType("application/json;charset=UTF-8");
response.setCharacterEncoding("UTF-8");
PrintWriter pw = response.getWriter();
int num = 0;
boolean flag = false; if(flag)num=0;else num=1;
pw.write(num);
pw.flush();

<action name="pageTest" class="pageTestAction" method="abc">
<result name="success">
/jsp/card/inventory/testString.jsp
</result>
</action>

testString.jsp:
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="GBK"%>
这个页面就这个，什么都不要。
然后你再alert()试试？

Answer 2

返回json数据就行
<action name="pageTest" class="pageTestAction" method="abc">
<result type="json">
<param name="includeProperties">action里的boolean变量名</param>
</result>
</action>
然后jquery读json

Answer 3

直接判断字符串不就好了。。

Answer 4
