map组件,polyline.points更新后,页面没有刷新JS中动态改了polyline.points,因为polyline是数组,所以我设置了第一个个元素[0],从log中可以看到后台数据确实是改变了,但是地图上的polyline始终没有变化,应该是个bug WXML文件内容: <map id="map" longitude="{{x}}" latitude="{{y}}" scale="14" controls="{{controls}}" bindcontroltap="controltap" markers="{{markers}}" bindmarkertap="markertap" polyline="{{polyline}}" bindregionchange="regionchange" bindcontroltap="moveToLocation" show-location style="width: 100%; height: 60vh;"></map> <button bindtap="test" class="weui-btn mini-btn" type="primary" size="mini">选取坐标</button> JS文件内容: test: function () { var testpoints = [{ longitude: 121.43686999999998, latitude: 31.18826000000001 }, { longitude: 113.324520, latitude: 23.21229 }] this.data.polyline[0].points = testpoints }, JS文件中的data内容: data: { polyline: [{ points: [{ longitude: 113.3245211, latitude: 23.10229 }, { longitude: 113.324520, latitude: 23.21229 }], color: "#FF0000DD", width: 2, dottedLine: true }] }
