java ajax传递到action_day8——ajax传参到action（Struts2）

第一种：url+?+参数

jsp中：

$(function(){

$("[name='delemp']").click(function(){

$this = $(this);

$delid = $this.attr("delid");

if(confirm("确认删除该条数据吗？")){

$.ajax({

type:"get",

url:"deleteemployeebyid?delid="+$delid,

dataType:"json",

success:function(msg){

$this.parent().parent().parent().remove();

alert(msg);

}

});

}else{

return false;

}

})

action中：

public String delEmployeesById(){

Map map = ActionContext.getContext().getParameters();

Object[] delid = (Object[]) map.get("delid");

String deleteid = (String) delid[0];

Integer did = Integer.valueOf(deleteid);

Employees emp = new Employees();

emp.setId(did);

employeesService.deleteEmployeeById(emp);

return SUCCESS;

}

第二种：post请求传递，action属性接收(推荐)

jsp:

………………

$.ajax({

type:"post",

url:"deleteemployeebyid,

dataType:"json",

data:{"delId":$delid},

success:function(msg){

$this.parent().parent().parent().remove();

alert(msg);

}

………………

action:

private Integer delId;

getter/setter方法

private String jsonobj;　　//删除success后返回的msg

getter/setter

………………具体方法中直接用delId

struts.xml:(json结果配置)

jsonObj
