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="javascr>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>

CSS樣式：

.conSixmap{position:relative;width:678px;height:335px;margin:0 auto;background:url(../images/tuanduimapBg.png) no-repeat;color:#000;font-family:"微軟雅黑"}.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": [        "請求的json數(shù)據(jù)1",        "請求的json數(shù)據(jù)2"    ],    "nanmeizhou": [        "請求的json數(shù)據(jù)3",        "請求的json數(shù)據(jù)4"    ],    "ouzhou": [        "請求的json數(shù)據(jù)5",        "請求的json數(shù)據(jù)6",        "請求的json數(shù)據(jù)7",        "請求的json數(shù)據(jù)8"    ],    "feizhou": [        "請求的json數(shù)據(jù)9",        "請求的json數(shù)據(jù)10",        "請求的json數(shù)據(jù)11",        "請求的json數(shù)據(jù)12"    ],    "yazhou": [        "請求的json數(shù)據(jù)13",        "請求的json數(shù)據(jù)14"    ],    "dayangzhou": [        "請求的json數(shù)據(jù)15",        "請求的json數(shù)據(jù)16"    ]}

js代碼：

$(document).ready(function(){    //添加地圖    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('請求失敗，請檢查網(wǎng)絡(luò)');            }        });     });});
