微信小程序显示地图与定位实现,比起用Vue实现要简单得多。下面说一下代码: 1.页面
<!--index.wxml--> <view class='view'> <map longitude="{{longitude}}" latitude="{{latitude}}" markers="{{markers}}" covers="{{covers}}" show-location> <cover-view> 经度:{{longitude}} </cover-view> <cover-view> 纬度:{{latitude}} </cover-view> <cover-view> 速度:{{speed}} </cover-view> <cover-view> 精度:{{accuracy}} </cover-view> </map> </view>2.定位
//index.js //获取应用实例 const app = getApp() Page({ data: { longitude:116.4965075, latitude: 40.006103, speed:0, accuracy:0 }, //事件处理函数 bindViewTap: function() { }, onLoad: function () { var that=this wx.showLoading({ title:"定位中", mask:true }) wx.getLocation({ type: 'gcj02', altitude:true,//高精度定位 //定位成功,更新定位结果 success: function (res) { var latitude = res.latitude var longitude = res.longitude var speed = res.speed var accuracy = res.accuracy that.setData({ longitude:longitude, latitude: latitude, speed: speed, accuracy: accuracy }) }, //定位失败回调 fail:function(){ wx.showToast({ title:"定位失败", icon:"none" }) }, complete:function(){ //隐藏定位中信息进度 wx.hideLoading() } }) }, })3.样式(全屏)
/**index.wxss**/ /* 不加page无法全屏 */ page { height: 100%; } .view { width: 100%; height: 100%; } map { width: 100%; height: 100%; background-color: red; }效果图:
