在小程式中顯示地圖並新增標註的教程

阿新 • • 發佈：2019-01-26

前言

需求：

  • 在小程式裡顯示地圖，並標記地圖上的一個座標點。
  • 管理員可以在後臺設定座標點

在這裡插入圖片描述

小程式顯示地圖和座標點

.wxml檔案

<view style="display:flex; justify-content:center;" >
  <map id="myMap" style="width: 90%; height: 600rpx;"
  longitude="{{longitude}}"
  latitude="{{latitude}}"
  scale="15" markers="{{markers}}" ></map>
</view>

解釋：

  • longitude ： 經度
  • latitude ： 緯度
  • scale ： 縮放級別，取值範圍為5-18
  • markers ： 標記點

.js 檔案

data: {
    longitude: 116.404008,
    latitude: 39.914209,
    markers:[]
},

/**
* 生命週期函式--監聽頁面初次渲染完成
*/
onReady: function () {
    this.mapCtx = wx.createMapContext('myMap')
},

從後臺介面獲取到座標資料後，要把資料渲染到地圖上。

介面主要有兩個資料，一個是經度longitude，一個是維度latitude

var marker = {
  id: 1,
  latitude: data.latitude,
  longitude: data.longitude
}
var markers = new Array();
markers.push(marker);

this.setData({
  markers: markers,
  latitude: data.latitude,
  longitude: data.longitude
});

這樣就能得到開頭的那種顯示效果了。

後臺設定座標點

使用百度地圖在地圖上進行選點，效果如下：

                var marker = new BMap.Marker(pt); // 建立標註
                map.addOverlay(marker); // 將標註新增到地圖中
            });

            var ac = new BMap.Autocomplete( //建立一個自動完成的物件
                {
                    "input": "suggestId",
                    "location": map
                });

            ac.addEventListener("onhighlight", function(e) { //滑鼠放在下拉列表上的事件
                var str = "";
                var _value = e.fromitem.value;
                var value = "";
                if (e.fromitem.index > -1) {
                    value = _value.province + _value.city + _value.district + _value.street + _value.business;

                str = "FromItem<br />index = " + e.fromitem.index + "<br />value = " + value;

                value = "";

            });

            function setPlace() {
                map.clearOverlays(); //清除地圖上所有覆蓋物
                function myFun() {
                    var pp = local.getResults().getPoi(0).point; //獲取第一個智慧搜尋的結果
                    map.centerAndZoom(pp, 18);
                    map.addOverlay(new BMap.Marker(pp)); //新增標註
                }

                var local = new BMap.LocalSearch(map, { //智慧搜尋
                    onSearchComplete: myFun
                });
                local.search(myValue);
            }
        </script>
</body>
</html>

注：

  • 引入百度地圖api，主要注意修改為自己的ak
    <script type="text/javascript" src="https://api.map.baidu.com/api?v=2.0&ak=申請的祕鑰AK"></script>

  • 為地圖新增點選事件，並建立標註

map.addEventListener("click", function(e) {
    var pt = e.point;
    map.clearOverlays(); // 清除覆蓋物
    var marker = new BMap.Marker(pt); // 建立標註
    map.addOverlay(marker); // 將標註新增到地圖中
});

新增搜尋的功能

可以模糊搜尋地名快速定位到想要的地點，效果如下：

在這裡插入圖片描述

主要使用了百度地圖的api，主要是建立一個自動完成的物件，具體程式碼可以參照上面的demo

var ac = new BMap.Autocomplete(
{
    "input": "suggestId",
    "location": map
});

最後在兩個input元素，lng和lat，就能得到座標點的經度和維度，儲存到資料庫就可以提供給小程式呼叫了。

在使用中發現百度地圖得到的座標資料放到小程式裡就會出現不小的偏差，因為小程式裡使用的是騰訊地圖，（當然也可以選擇高德地圖），偏差大概有500米，這個是無法忍受的，所以決定後臺換成騰訊地圖。

騰訊地圖設定座標點

同樣需要去 騰訊地圖開放平臺 https://lbs.qq.com/ ，申請一個key，作用跟百度地圖的ak一樣。

下面的程式碼是仿照騰訊地圖提供的示例寫的，因為裡面包含了全國市級行政的資料，所以顯得程式碼量很大。
