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<String,Object> 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)
<!-- json响应,返回单个Object -->
<result name="retJsonObj" type="json">
<param name="root">jsonObj</param>
</result>
