多级联动封装





duoji.js 代码

(function ($) {
$.select=function(box,addInputClass){
var i=new select;
return i.init(box,addInputClass)
}
//声明多级联动 方法类
var select = new Function();
select.prototype={
//定义类属性
init:function(box,addInputClass){
this.boxName=box;
this.box=$('#'+box); //需要添加元素的容器
this.eleClass=addInputClass;//每个事件的定位class
this.first();//新建一个select获取 
},
first:function(){
//声明外部变量
var boxName=this.boxName;
var eleClass= this.eleClass;
var box=this.box;
var obj=this;
$.get("http://127.0.0.1:83/areas", {id:'0'},
function(data){
var option="";
var list=data.data;
for(var key in list){
option+="";
}
$('
').appendTo(box).find('select').bind('change',function(){obj.change($(this))}); },'jsonp'); }, //change事件 change:function(event){ //声明 var boxName=$(event).attr('pnode'); //获取触发事件者的pnode var className=$(event).attr('cname');//获取触发事件者的cname var box =$("#"+boxName); //获取所有插入盒子的对象 var eleClass=$("."+className); //获取所有Class所在元素组 var num=eleClass.index($(event))+1; //获取num的值 var id=$(event).val(); //获取ajax发送id的头 var obj=this; //代表这个方法 //清除 后续添加的新的元素 eleClass.each(function(){ //这里的this 代表eleClass 遍历时的单个对象 //console.log($(this).attr('num')); //console.log($().attr('num')); if($(this).attr('num')>$(event).attr('num')){ $(this).parent().remove(); } }); /* console.log(boxName); console.log(className); console.log($(event)); console.log($(event).val()); */ //循环ajax方法 $.ajax({ type: "get", dataType:"jsonp", url: "http://127.0.0.1:83/areas", data: {id:id}, sync: false,//设置为同步 success: function(data){ //console.log(data); var list =data.data if(data.state==='1'){ var option=""; for(var key in list){ option+=""; } $('
').appendTo(box).find('select').bind('change',function(){obj.change(this)}); } } }); }, //查询当前盒子中的信息 log:function(){ var boxName=$(event).attr('pnode'); //获取触发事件者的pnode var className=$(event).attr('cname');//获取触发事件者的cname var box =$("#"+boxName); //获取所有插入盒子的对象 var eleClass=$("."+className); //获取所有Class所在元素组 console.log("容器名:"+boxName+"\n 触发的class名:"+className); }, //第一个select框获取信息 getFirstElement:function(){ var main=$('#'+this.main); $.get("http://127.0.0.1:83/areas", {id:'0'}, function(data){ var option=""; var list=data.data; for(var key in list){ option+=""; } main.html(option); },'jsonp'); } } })(jQuery)

后端提供的数据类型:json

如果有数据:state=1

例子:

data:{
110000:{id: "110000", areaname: "北京", pid: "0", shortname: "北京", level: "1", position: "tr_0", sort: "1"}
120000:{id: "120000", areaname: "天津", pid: "0", shortname: "天津", level: "1", position: "tr_0", sort: "2"}
130000:{id: "130000", areaname: "河北省", pid: "0", shortname: "河北", level: "1", position: "tr_0", sort: "3"}
140000:{id: "140000", areaname: "山西省", pid: "0", shortname: "山西", level: "1", position: "tr_0", sort: "4"}
150000:{id: "150000", areaname: "内蒙古自治区", pid: "0", shortname: "内蒙古", level: "1", position: "tr_0", sort: "5"}
210000:{id: "210000", areaname: "辽宁省", pid: "0", shortname: "辽宁", level: "1", position: "tr_0", sort: "6"}
220000:{id: "220000", areaname: "吉林省", pid: "0", shortname: "吉林", level: "1", position: "tr_0", sort: "7"}
230000:{id: "230000", areaname: "黑龙江省", pid: "0", shortname: "黑龙江", level: "1", position: "tr_0", sort: "8"}
310000:{id: "310000", areaname: "上海", pid: "0", shortname: "上海", level: "1", position: "tr_0", sort: "9"}
320000:{id: "320000", areaname: "江苏省", pid: "0", shortname: "江苏", level: "1", position: "tr_0", sort: "10"}
330000:{id: "330000", areaname: "浙江省", pid: "0", shortname: "浙江", level: "1", position: "tr_0", sort: "11"}
.....
},
state:"1"

如果没有数据 state=0

例子:

state:"0"
