echarts地图实现地区下钻

今天使用echarts做了一个地图的下钻，上网找了各种资料之后终于完成了！具体代码可以区我的github上观看 https://github.com/yunpengLiang/echarts
下载下来之后不能在本地直接访问，因为使用jquery的$.getJSON获取json，产生了跨域，需要放到项目中使用http开头的访问


$(function () {map();function map() {// 基于准备好的dom，初始化echarts实例var myChart = echarts.init(document.getElementById('map'));//存储切换的每一级地图信息var mapStack = [];var timeFn = null;var curMap = {};//初始化地图loadMap('100000', 'china');/**绑定用户切换地图区域事件cityMap对象存储着地图区域名称和区域的信息(name-code)当mapCode有值,说明可以切换到下级地图同时保存上级地图的编号和名称  */myChart.on('click', function(params) {clearTimeout(timeFn);//由于单击事件和双击事件冲突，故单击的响应事件延迟250毫秒执行timeFn = setTimeout(function(){var name = params.name;var mapCode = cityMap[name];if (!mapCode) {alert('无此区域地图显示');return;}loadMap(mapCode, name);    //将上一级地图信息压入mapStackmapStack.push({mapCode: curMap.mapCode,mapName: curMap.mapName});   }, 250);   });/**绑定双击事件，并加载上一级地图*/myChart.on('dblclick', function(params) {//当双击事件发生时，清除单击事件，仅响应双击事件clearTimeout(timeFn);var map = mapStack.pop();if (!mapStack.length && !map) {alert('已经到达最上一级地图了');return;}loadMap(map.mapCode, map.mapName);});var dataValue = [{name: '海门', value: 9},{name: '鄂尔多斯', value: 12},{name: '招远', value: 12},{name: '舟山', value: 12},{name: '齐齐哈尔', value: 14},{name: '盐城', value: 15},{name: '赤峰', value: 16},{name: '青岛', value: 18},{name: '乳山', value: 18},{name: '金昌', value: 19},{name: '泉州', value: 21},{name: '莱西', value: 21},{name: '日照', value: 21},{name: '胶南', value: 22},{name: '南通', value: 23},{name: '拉萨', value: 24},{name: '云浮', value: 24},{name: '梅州', value: 25},{name: '文登', value: 25},{name: '上海', value: 25},{name: '大庆', value: 279}];var geoCoordMap = {'海门':[121.15,31.89],'鄂尔多斯':[109.781327,39.608266],'招远':[120.38,37.35],'舟山':[122.207216,29.985295],'齐齐哈尔':[123.97,47.33],'盐城':[120.13,33.38],'赤峰':[118.87,42.28],'青岛':[120.33,36.07],'乳山':[121.52,36.89],'金昌':[102.188043,38.520089],'泉州':[118.58,24.93],'莱西':[120.53,36.86],'日照':[119.46,35.42],'胶南':[119.97,35.88],'南通':[121.05,32.08],'拉萨':[91.11,29.97],'云浮':[112.02,22.93],'梅州':[116.1,24.55],'文登':[122.05,37.2],'上海':[121.48,31.22],'攀枝花':[101.718637,26.582347],'威海':[122.1,37.5],'承德':[117.93,40.97],'厦门':[118.1,24.46],'汕尾':[115.375279,22.786211],'潮州':[116.63,23.68],'丹东':[124.37,40.13],'太仓':[121.1,31.45],'曲靖':[103.79,25.51],'烟台':[121.39,37.52],'福州':[119.3,26.08],'瓦房店':[121.979603,39.627114],'即墨':[120.45,36.38],'抚顺':[123.97,41.97],'玉溪':[102.52,24.35],'张家口':[114.87,40.82],'阳泉':[113.57,37.85],'莱州':[119.942327,37.177017],'湖州':[120.1,30.86],'汕头':[116.69,23.39],'昆山':[120.95,31.39],'宁波':[121.56,29.86],'湛江':[110.359377,21.270708],'揭阳':[116.35,23.55],'荣成':[122.41,37.16],'连云港':[119.16,34.59],'葫芦岛':[120.836932,40.711052],'常熟':[120.74,31.64],'东莞':[113.75,23.04],'河源':[114.68,23.73],'淮安':[119.15,33.5],'泰州':[119.9,32.49],'南宁':[108.33,22.84],'营口':[122.18,40.65],'惠州':[114.4,23.09],'江阴':[120.26,31.91],'蓬莱':[120.75,37.8],'韶关':[113.62,24.84],'嘉峪关':[98.289152,39.77313],'广州':[113.23,23.16],'延安':[109.47,36.6],'太原':[112.53,37.87],'清远':[113.01,23.7],'中山':[113.38,22.52],'昆明':[102.73,25.04],'寿光':[118.73,36.86],'盘锦':[122.070714,41.119997],'长治':[113.08,36.18],'深圳':[114.07,22.62],'珠海':[113.52,22.3],'宿迁':[118.3,33.96],'咸阳':[108.72,34.36],'铜川':[109.11,35.09],'平度':[119.97,36.77],'佛山':[113.11,23.05],'海口':[110.35,20.02],'江门':[113.06,22.61],'章丘':[117.53,36.72],'肇庆':[112.44,23.05],'大连':[121.62,38.92],'临汾':[111.5,36.08],'吴江':[120.63,31.16],'石嘴山':[106.39,39.04],'沈阳':[123.38,41.8],'苏州':[120.62,31.32],'茂名':[110.88,21.68],'嘉兴':[120.76,30.77],'长春':[125.35,43.88],'胶州':[120.03336,36.264622],'银川':[106.27,38.47],'张家港':[120.555821,31.875428],'三门峡':[111.19,34.76],'锦州':[121.15,41.13],'南昌':[115.89,28.68],'柳州':[109.4,24.33],'三亚':[109.511909,18.252847],'自贡':[104.778442,29.33903],'吉林':[126.57,43.87],'阳江':[111.95,21.85],'泸州':[105.39,28.91],'西宁':[101.74,36.56],'宜宾':[104.56,29.77],'呼和浩特':[111.65,40.82],'成都':[104.06,30.67],'大同':[113.3,40.12],'镇江':[119.44,32.2],'桂林':[110.28,25.29],'张家界':[110.479191,29.117096],'宜兴':[119.82,31.36],'北海':[109.12,21.49],'西安':[108.95,34.27],'金坛':[119.56,31.74],'东营':[118.49,37.46],'牡丹江':[129.58,44.6],'遵义':[106.9,27.7],'绍兴':[120.58,30.01],'扬州':[119.42,32.39],'常州':[119.95,31.79],'潍坊':[119.1,36.62],'重庆':[106.54,29.59],'台州':[121.420757,28.656386],'南京':[118.78,32.04],'滨州':[118.03,37.36],'贵阳':[106.71,26.57],'无锡':[120.29,31.59],'本溪':[123.73,41.3],'克拉玛依':[84.77,45.59],'渭南':[109.5,34.52],'马鞍山':[118.48,31.56],'宝鸡':[107.15,34.38],'焦作':[113.21,35.24],'句容':[119.16,31.95],'北京':[116.46,39.92],'徐州':[117.2,34.26],'衡水':[115.72,37.72],'包头':[110,40.58],'绵阳':[104.73,31.48],'乌鲁木齐':[87.68,43.77],'枣庄':[117.57,34.86],'杭州':[120.19,30.26],'淄博':[118.05,36.78],'鞍山':[122.85,41.12],'溧阳':[119.48,31.43],'库尔勒':[86.06,41.68],'安阳':[114.35,36.1],'开封':[114.35,34.79],'济南':[117,36.65],'德阳':[104.37,31.13],'温州':[120.65,28.01],'九江':[115.97,29.71],'邯郸':[114.47,36.6],'临安':[119.72,30.23],'兰州':[103.73,36.03],'沧州':[116.83,38.33],'临沂':[118.35,35.05],'南充':[106.110698,30.837793],'天津':[117.2,39.13],'富阳':[119.95,30.07],'泰安':[117.13,36.18],'诸暨':[120.23,29.71],'郑州':[113.65,34.76],'哈尔滨':[126.63,45.75],'聊城':[115.97,36.45],'芜湖':[118.38,31.33],'唐山':[118.02,39.63],'平顶山':[113.29,33.75],'邢台':[114.48,37.05],'德州':[116.29,37.45],'济宁':[116.59,35.38],'荆州':[112.239741,30.335165],'宜昌':[111.3,30.7],'义乌':[120.06,29.32],'丽水':[119.92,28.45],'洛阳':[112.44,34.7],'秦皇岛':[119.57,39.95],'株洲':[113.16,27.83],'石家庄':[114.48,38.03],'莱芜':[117.67,36.19],'常德':[111.69,29.05],'保定':[115.48,38.85],'湘潭':[112.91,27.87],'金华':[119.64,29.12],'岳阳':[113.09,29.37],'长沙':[113,28.21],'衢州':[118.88,28.97],'廊坊':[116.7,39.53],'菏泽':[115.480656,35.23375],'合肥':[117.27,31.86],'武汉':[114.31,30.52],'大庆':[125.03,46.58]};var convertData = function (data) {var res = [];for (var i = 0;
