地图通过筛选框或者点击省,进入下一级市,地图视角中心点边界跟着切换,如下图省为湖北,但是目前从省到市的时候边界无法切换如图二,请大神赐教目前的JS如下setTimeout(function() {var city_name = duchamp.getWidgetByName("city").getValue();var province_name = duchamp.getWidgetByName("province").getValue();if (city_name.length != 0) {var lon = parseFloat(FR.remoteEvaluate('=VALUE("城市数据",2,1,"'+city_name+'")'));var lat = parseFloat(FR.remoteEvaluate('=VALUE("城市数据",3,1,"'+city_name+'")'));var zoom = parseFloat(FR.remoteEvaluate('=VALUE("城市数据",4,1,"'+city_name+'")'));duchamp.getWidgetByName("地图1").setMapZoom({zoomLevel: zoom, viewCenter: });}else{duchamp.getWidgetByName("地图1").setMapZoom({zoomLevel: 4, viewCenter: });}}, 50)
