AJAX在Struts2中使用

前台页面：

    pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>

    $(function(){
        //1点击删除的时候，确定删除吗？
        $(".delete").click(function(){
        var lastName=$(this).next(":input").val();
             var flag=confirm("确定要"+lastName+"删除吗？");
             if(flag){
                 //删除，使用ajax的方式
                 var url=this.href;
                 var args={"time":new Date()};
                 $.post(url,args,function(data){
                     if(data=="1"){
                     alert("删除成功");
                     $tr.remove();
                     }else{

             }

             return false;

</script>

<body>
    
    <h4>Employee List Page</h4>
    
    <s:if test="#request.employees == null || #request.employees.size() == 0">
        没有任何员工信息
    </s:if>
    <s:else>
        <table border="1" cellpadding="10" cellspacing="0">

            </s:iterator>
        </table>
    </s:else>
        
</body>
</html>

ACTION中：

public String delete(){
        
        try {
            employeeService.deleteEmployee(id);
            inputStream = new ByteArrayInputStream("1".getBytes("UTF-8"));
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
            try {
                inputStream=new ByteArrayInputStream("0".getBytes("UTF-8"));
            } catch (UnsupportedEncodingException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }

        }
        return "delete";
    }

    private InputStream inputStream;
    public InputStream getInputStream() {
        return inputStream;
    }

struts.xml文件中：

<package name="default" namespace="/" extends="struts-default">
        <action name="emp-*" class="employeeAction"
            method="{1}">
        <result name="list">/emp-list.jsp</result>
    
        <result type="stream" name="delete">
            <param name="contentType">text/html</param>
            <param name="inputName">inputStream</param>
        </result>
        </action>
       
    </package>
