js代碼：

$(document).ready(function(){
    //添加地圖
    var stauteArr={
            'beimeizhou':'true',
            'nanmeizhou':'true',

            'yazhou':'true',
            'dayangzhou':'true'
        };
    $(".conSixmap .name").on('click',function(){
        var _this=this;
        var htmlcon="";
        $(this).siblings(".name").children(".condetail").fadeOut(500);
        $(this).children(".condetail").fadeIn(500);
        var _name=$(this).attr('data-name');
          $.ajax({
            url:"js/schoolMap.json",
            type:'get',
            data:{},

                for(var i in data){
                    if(_name==i && stauteArr[i]=='true'){
                        for(var j=0;j<data[i].length;j++){
                             htmlcon+="<span>"+data[i][j]+"</span>";
                        }
