摘要:本文以【唱吧】531麦霸音乐节为案例,详细解读了如何导入自有数据到高德云图,并进行检索和展示。最后,调起高德mobile地图来进行路线规划和周边查询。
本案例可以应用在微信开发平台,支付宝公众服务上,适合餐饮商家,汽车4S店,银行,停车场等业务。
由于使用高德云图+URI API的方式实现,开发者无需进行繁琐的数据库操作,即可实现自有数据的存储与检索。
效果图:
--------------------------------------------------------------
一、数据准备
从唱吧531麦霸节官网获得数据:http://changba.com/yunying/ktvStaticList.php
拷贝到excel,另存为CSV格式,并改成UTF-8或者GBK编码。
二、导入数据
登录云图:http://yuntu.amap.com/datamanager/index.html
点击新建地图:
导入刚才的数据:
点击预览:
出现全国KTV分布图:
三、UE设计图
1、对于KTV的展示,有列表模式和地图模式2种。
2、按照城市检索并展示KTV数据。
3、点击某个KTV,跳转到高德mobile地图,进行路线规划。
四、云图展示全国KTV
采用云图层的方法,将麻点图展示出来。
//地图-云图层
mapObj.plugin('AMap.CloudDataLayer', function () {
var layerOptions = {
query:{keywords: ''},
clickable:true
};
cloudDataLayer = new AMap.CloudDataLayer('538d71fee4b04192f1f4de77', layerOptions); //实例化云图层类
cloudDataLayer.setMap(mapObj); //叠加云图层到地图
});
示例图:
五、列表展示北京市KTV
用云检索,检索出北京市的KTV。
//列表
mapObj.plugin(["AMap.CloudDataSearch"], function() { var searchOptions = {
keywords:'',
orderBy:'_id:ASC'
};
cloudSearch = new AMap.CloudDataSearch('538d71fee4b04192f1f4de77', searchOptions); //构造云数据检索类
AMap.event.addListener(cloudSearch, "complete", cloudSearch_CallBack); //查询成功时的回调函数
AMap.event.addListener(cloudSearch, "error", errorInfo); //查询失败时的回调函数
cloudSearch.searchNearBy(iPoint, 30000); //周边检索
});
示例图:
六、采用URI API链接到高德mobile地图
在点击列表,和点击麻点图的时候,采取URI API的方式调取地图。
这样我们只需要知道一个经纬度,就可以调取地图。
示例:
http://mo.amap.com/?q=31.234527,121.287689&name=名字
列表调取mo的代码:
//回调函数-成功
function cloudSearch_CallBack(data) {
var resultStr="";
var resultArr = data.datas;
var resultNum = resultArr.length;
for (var i = 0; i < resultNum; i++) {
resultStr += "<div class=\"item\">";
resultStr += "<a href='http://mo.amap.com/?q=" + resultArr[i]._location.getLat() + "," + resultArr[i]._location.getLng() + "&name=" + resultArr[i]._name + "'><h3>" + (i+1) + "、" + resultArr[i]._name + "</h3></a>";
resultStr += "<p>地址:" + resultArr[i]._address + "</p>";
resultStr += "<p>电话:" + resultArr[i].tel + "</p>";
resultStr += "</div>";
}
document.getElementById("list").innerHTML = resultStr;
}
点击麻点图,出现信息窗口,调取高德mo:
AMap.event.addListener(cloudDataLayer, 'click', function (result) {
var clouddata = result.data;
//云图麻点
var infoWindow = new AMap.InfoWindow({
content: "<a href='http://mo.amap.com/?q=" + clouddata._location.getLat() + "," + clouddata._location.getLng() + "&name=" + clouddata._name + "'><h3>" + clouddata._name + "</h3></a>" + "<p>地址:" + clouddata._address + "</p>" + "<p>电话:" + clouddata.tel + "</p>",
size:new AMap.Size(300, 0),
autoMove:true,
offset:new AMap.Pixel(0,-5)
});
infoWindow.open(mapObj, clouddata._location);
});

七、城市切换
城市切换的时候,云图层展示,和云检索list要分开写。
//索引云图
function getType(iPrivance){
if(iPrivance=="全国"){
mapObj.setZoomAndCenter(4,new AMap.LngLat(114.433594,33.651208));
myCloudList('');
var op={
query:{keywords:""}
};
cloudDataLayer.setOptions(op);
}else{
myCloudList(iPrivance);
var op={
query:{keywords:iPrivance}
};
cloudDataLayer.setOptions(op);
placeSearch(iPrivance);
}
}
地图展示完毕之后,需要重新设置中心点。
//城市查询
function placeSearch(id) {
var MSearch;
mapObj.plugin(["AMap.PlaceSearch"], function() {
MSearch = new AMap.PlaceSearch({ //构造地点查询类
pageSize:1,
pageIndex:1,
city:"" //城市
});
AMap.event.addListener(MSearch, "complete", keywordSearch_CallBack);//返回地点查询结果
MSearch.search(id); //关键字查询
});
}
//城市查询后定位
function keywordSearch_CallBack(data) {
var iPoint = data.poiList.pois[0].location;
mapObj.setZoomAndCenter(10,iPoint);
}
