当小程序地图缩小怎么使标记（覆盖物）消失
我写了一个小程序，我希望它可以当地图缩小scale<17时覆盖物消失，不知道大神怎么做，下面是我的代码： bindcontroltap(e) { if (scale < 17) { markers: [ { iconPath: "/images/1.png", id: 3, latitude: 23.6290537532, longitude: 113.6763632298, width: 30, height: 30, alpha: 0.8, display: none , callout: { content: " 工程师 ", color: "#ffffff", fontSize: 10, borderRadius: 10, bgColor: "#6e707c", padding: 5, // display: "ALWAYS" } }, { iconPath: "/resources/user.png", id: 4, latitude: 23.6326040919, longitude: 113.6791991184, width: 30, height: 30, alpha: 0.8, callout: { content: " 工程师 ", color: "#ffffff", fontSize: 10, borderRadius: 10, bgColor: "#6e707c", padding: 5, display: "BLCLICK" } } ] } else { markers: [ { iconPath: "/images/1.png", id: 3, latitude: 23.6290537532, longitude: 113.6763632298, width: 30, height: 30, alpha: 0.8, display: "ALWAYS", callout: { content: " 工程师 ", color: "#ffffff", fontSize: 10, borderRadius: 10, bgColor: "#6e707c", padding: 5, // display: "ALWAYS" } }, { iconPath: "/resources/user.png", id: 4, latitude: 23.6326040919, longitude: 113.6791991184, width: 30, height: 30, alpha: 0.8, callout: { content: " 工程师 ", color: "#ffffff", fontSize: 10, borderRadius: 10, bgColor: "#6e707c", padding: 5, display: "BLCLICK" } } ] }
