• 【云图】如何制作全国KTV查询系统?


    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);
    }
