- 预期表现
初始设置地图的默认缩放级别,scale="{{scale}}",scale:13
点击一个POI类型,在地图上显示先关的经纬度坐标点,然后调用MapContext.includePoints(Object object)聚合所有坐标点在地图视野范围内
在MapContext.includePoints(Object object)调用成功后回调MapContext.getScale(Object object),获取聚合后的地图缩放级别
虽然坐标点聚合完成后地图缩放级别产生明显变化,但是MapContext.getScale(Object object)返回的缩放级别仍旧是初始值
所以导致在点击地图上加号和减号的时候,地图缩放未能显示预期效果
- 提供一个最简复现 Demo
< map id = 'map' scale = "{{scale}}" show-location bindmarkertap = "bindmarkertap" markers = "{{markers}}" bindcontroltap = "bindcontroltap" longitude = "{{longitude}}" latitude = "{{latitude}}" > < cover-view bindtap = 'bindcontroltap' class = 'map-pos-box' > < cover-image src = '../../images/map-pos.png' mode = "widthFix" class = "map-pos" ></ cover-image > </ cover-view > < cover-view class = 'scalePuls' bindtap = 'scalePuls' >+</ cover-view > < cover-view class = 'scaleMinus' bindtap = 'scaleMinus' >-</ cover-view > </ map > |
Page({ data: { scale: 13 }, .... }) |
//初始化地图控件 this .mapCtx = wx.createMapContext( 'map' ); //聚合坐标点 this .mapCtx.includePoints({ padding: [35, 35, 35, 35], points: markers, complete: function () { //获取聚合坐标点之后获取地图缩放级别 that.mapCtx.getScale({ success: function (res) { //返回仍旧是初始化的scale:13 console.log(res.scale) that.setData({ scale: res.scale }) } }) } }) |
你好,麻烦提供出现问题的具体机型、微信版本号、系统版本号,以及能复现问题的代码片段(https://developers.weixin.qq.com/miniprogram/dev/devtools/minicode.html)
