<form action="" method="post" id="frm">
    		<table border="1" align="center">
    			<caption>

    					<input type="reset" value="重置" />
    				</td>
    			</tr>
    
    			</form>

脚本页面

$(function() {
    
    	// 单击事件
    	$("#button").click(function() {
    		// jQuery.post(url, [data], [callback], [type])
    		$.post("login.action", $("#frm").serialize(), function(data) {
    			if(data==1){
    				document.location.href="index.jsp";  //重定向
    			}else{
    				$("body").prepend("<div style='color:red;text-align:center'>用户名或密码错误！</div>");
    			}
    
    		}, "json");
    
    	});
    
    });

Action控制器

public String ajax_login() throws Exception {
    		// 调用方法
    		dept = biz.findIsLogin(dept);
    		// 判断
    		if (dept != null) {
    			session.put("depts", dept);
    			result = "1"; // 登录成功
    		} else {
    			result = "0"; // 登录失败
    		}
    
    		return SUCCESS;
    	}
    
    	Map<String, Object> session;
    
    	@Override
    	public void setSession(Map<String, Object> session) {
    		// TODO Auto-generated method stub
    		this.session = session;
    	}
