markers可以增加动态图标了吗？

同问，我也需要加动态图。用了一个方法，但是效果在手机上显示很慢，模拟器还好。看看有没有更好的方法加动态效果。 setInterval(() => { // marker脚下的圆圈渐变效果 for (let i in that.data.circles) { if (clearAlert[i]) { // 汽包是否被点击了？ if (that.data.circles[i].radius < 500) { that.data.circles[i].radius += 25; let newColor = that.data.circles[i].fillColor; if (newColor == "#FF0000") { newColor = "#FF4500"; } else if (newColor == "#FF4500") { newColor = "#FF6347" } else if (newColor == "#FF6347") { newColor = "#F08080"; } else if (newColor == "#F08080") { newColor = "#FF0000"; }; that.data.circles[i].color = newColor; that.data.circles[i].fillColor = newColor; } else { that.data.circles[i].radius = 0; that.data.circles[i].color = "#FF0000"; that.data.circles[i].fillColor = "#FF0000"; }; } else { that.data.circles[i].radius = 0; }; }; that.setData({ markers: that.data.mapData, circles: that.data.circles }) }, n);
