今天我们说到用百度提供的API搭建我们的小程序,好了,下来让我们进入正题: 首先我玩进入百度开放平台,获取对应账号和秘钥,获取方法在百度开放平台上有详细介绍http://lbsyun.baidu.com/index.php?title=wxjsapi/guide/key 这里我们就跳过。 在获取到账号和秘钥之后我们接下来就是配置环境了, 在我们项目下面新建一个libs目录,将在下载好的JavaScriptApi 里面的 bmap-wx.min.js 导入进来,环境就配置到这里。接下来我们就可以尽情搞技术了。 首先在我们的项目index文件夹中index.js中修改以下代码:(记住修改你的ak值)
// 引用百度地图微信小程序JSAPI模块 2 var bmap = require('../../libs/bmap-wx.js'); 3 var wxMarkerData = []; 4 Page({ 5 data: { 6 markers: [], 7 latitude: '', 8 longitude: '', 9 placeData: {} 10 }, 11 makertap: function(e) { 12 var that = this; 13 var id = e.markerId; 14 that.showSearchInfo(wxMarkerData, id); 15 that.changeMarkerColor(wxMarkerData, id); 16 }, 17 onLoad: function() { 18 var that = this; 19 // 新建百度地图对象 20 var BMap = new bmap.BMapWX({ 21 ak: '您的ak' 22 }); 23 var fail = function(data) { 24 console.log(data) 25 }; 26 var success = function(data) { 27 wxMarkerData = data.wxMarkerData; 28 that.setData({ 29 markers: wxMarkerData 30 }); 31 that.setData({ 32 latitude: wxMarkerData[0].latitude 33 }); 34 that.setData({ 35 longitude: wxMarkerData[0].longitude 36 }); 37 } 38 // 发起POI检索请求 39 BMap.search({ 40 "query": '酒店', 41 fail: fail, 42 success: success, 43 // 此处需要在相应路径放置图片文件 44 iconPath: '../../img/marker_red.png', 45 // 此处需要在相应路径放置图片文件 46 iconTapPath: '../../img/marker_red.png' 47 }); 48 }, 49 showSearchInfo: function(data, i) { 50 var that = this; 51 that.setData({ 52 placeData: { 53 title: '名称:' + data[i].title + '\n', 54 address: '地址:' + data[i].address + '\n', 55 telephone: '电话:' + data[i].telephone 56 } 57 }); 58 }, 59 changeMarkerColor: function(data, i) { 60 var that = this; 61 var markers = []; 62 for (var j = 0; j < data.length; j++) { 63 if (j == i) { 64 // 此处需要在相应路径放置图片文件 65 data[j].iconPath = "../../img/marker_yellow.png"; 66 } else { 67 // 此处需要在相应路径放置图片文件 68 data[j].iconPath = "../../img/marker_red.png"; 69 } 70 markers[j](data[j]); 71 } 72 that.setData({ 73 markers: markers 74 }); 75 } 76 })// 引用百度地图微信小程序JSAPI模块 77 var bmap = require('../../libs/bmap-wx.js'); 78 Page({ 79 data: { 80 sugData: '' 81 }, 82 // 绑定input输入 83 bindKeyInput: function(e) { 84 var that = this; 85 // 新建百度地图对象 86 var BMap = new bmap.BMapWX({ 87 ak: '您的ak' 88 }); 89 var fail = function(data) { 90 console.log(data) 91 }; 92 var success = function(data) { 93 var sugData = ''; 94 for(var i = 0; i < data.result.length; i++) { 95 sugData = sugData + data.result[i].name + '\n'; 96 } 97 that.setData({ 98 sugData: sugData 99 }); 100 } 101 // 发起suggestion检索请求 102 BMap.suggestion({ 103 query: e.detail.value, 104 region: '北京', 105 city_limit: true, 106 fail: fail, 107 success: success 108 }); 109 } 110 })
接着修改index文件夹下index.wxml的内容:
<view class="map_container"> 2 <map class="map" id="map" longitude="{{longitude}}" latitude="{{latitude}}" scale="14" show-location="true" markers="{{markers}}" bindmarkertap="makertap"></map> 3 </view> 4 <view class="place_info"> 5 <text>{{placeData.title}}</text> 6 <text>{{placeData.address}}</text> 7 <text>{{placeData.telephone}}</text> 8 </view>
最后我们修改index文件夹下index.wxss文件
完成以上步骤后我们就可以看到效果了
