今天有這樣一個需求，點擊六個大洲，出現(xiàn)對應(yīng)的一些請求信息，展示在下面，請求請求過后，第二次點擊就無需請求。
如圖所示：點擊北美洲下面出現(xiàn)請求的一些數(shù)據(jù)

html代碼結(jié)構(gòu)：

<div class="conSixmap">
  <div class="name conmap01" data-name="beimeizhou">
    <a href="javascript:void(0)">北美洲</a>
    <div class="condetail"></div>
  </div>
  <div class="name conmap02" data-name="nanmeizhou">
    <a href="javascript:void(0)">南美洲</a>
    <div class="condetail"></div>
  </div>
  <div class="name conmap03" data-name="ouzhou">
    <a href="javascript:void(0)">歐洲</a>
    <div class="condetail"></div>
  </div>
  <div class="name conmap04" data-name="feizhou">
    <a href="javascript:void(0)">非洲</a>
    <div class="condetail"></div>
  </div>
  <div class="name conmap05" data-name="yazhou">
    <a href="javascript:void(0)">亞洲</a>
    <div class="condetail"></div>
  </div>
  <div class="name conmap06" data-name="dayangzhou">
    <a href="javascript:void(0)">大洋洲</a>
    <div class="condetail"></div>
  </div>
</div>

      'ouzhou':'true',
      'feizhou':'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",

        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>";
            }
            $(_this).children(".condetail").append(htmlcon);
            stauteArr[i]='false';
          }
        }
      },
      error: function(){
