今天有这样一个需求，点击六个大洲，出现对应的一些请求信息，展示在下面，请求请求过后，第二次点击就无需请求。
如图所示：点击北美洲下面出现请求的一些数据

html代码结构：

<div class="conSixmap">  <div class="name conmap01" data-name="beimeizhou">    <a href="">北美洲</a>    <div class="condetail"></div>  </div>  <div class="name conmap02" data-name="nanmeizhou">    <a href="">南美洲</a>    <div class="condetail"></div>  </div>  <div class="name conmap03" data-name="ouzhou">    <a href="">欧洲</a>    <div class="condetail"></div>  </div>  <div class="name conmap04" data-name="feizhou">    <a href="">非洲</a>    <div class="condetail"></div>  </div>  <div class="name conmap05" data-name="yazhou">    <a href="">亚洲</a>    <div class="condetail"></div>  </div>  <div class="name conmap06" data-name="dayangzhou">    <a href="">大洋洲</a>    <div class="condetail"></div>  </div></div> 

css样式：

.conSixmap{position:relative;width:678px;height:335px;margin:0 auto;background:url(../images/tuanduimapBg.png) no-repeat;color:#000;font-family:"微软雅黑"}.conSixmap .name .condetail{display:none;position:absolute;z-index:10;width:216px;padding:10px;left:50%;margin-left:-118px;top:54px;background:url(../images/opcity83.png) repeat;border-radius:5px;}.conSixmap .condetail span{display:block;color:#fff;font-size:14px;text-align:left;}.conSixmap .name{position:absolute;width:52px;height:55px;}.conSixmap .name a{display:block;z-index:2;position:absolute;padding-top:35px;text-align:center;cursor:pointer;width:52px;height:20px;color:#000;font-size:12px;}.conSixmap .conmap01{left:91px;top:73px;}.conSixmap .conmap01 a{background:url(../images/beimeipicBg.png) no-repeat top center;}.conSixmap .conmap02 {left:180px;top:213px;}.conSixmap .conmap02 a{background:url(../images/nanmeimapbg.png) no-repeat top center;}.conSixmap .conmap03 {left:339px;top:68px;}.conSixmap .conmap03 a{background:url(../images/ouzhoumapBg.png) no-repeat top center;}.conSixmap .conmap04{left:327px;top:158px;}.conSixmap .conmap04 a{background:url(../images/feizhoumapbg.png) no-repeat top center;}.conSixmap .conmap05 {left:480px;top:75px;}.conSixmap .conmap05 a{background:url(../images/yazhoumapBg.png) no-repeat top center;}.conSixmap .conmap06 {left:545px;top:220px;}.conSixmap .conmap06 a{background:url(../images/dayangmapbg.png) no-repeat top center;}

json格式：

{  "beimeizhou": [    "请求的json数据1",    "请求的json数据2"  ],  "nanmeizhou": [    "请求的json数据3",    "请求的json数据4"  ],  "ouzhou": [    "请求的json数据5",    "请求的json数据6",    "请求的json数据7",    "请求的json数据8"  ],  "feizhou": [    "请求的json数据9",    "请求的json数据10",    "请求的json数据11",    "请求的json数据12"  ],  "yazhou": [    "请求的json数据13",    "请求的json数据14"  ],  "dayangzhou": [    "请求的json数据15",    "请求的json数据16"  ]}

js代码：

$(document).ready(function(){  //添加地图  var stauteArr={      'beimeizhou':'true',      'nanmeizhou':'true',      'ouzhou':'true',      'feizhou':'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:{},      dataType:"json",      success: function(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>";            }            $(_this).children(".condetail").append(htmlcon);            stauteArr[i]='false';          }        }      },      error: function(){        alert('请求失败，请检查网络');      }    });  });});
