如何在openlayers中获取当前缩放

Question

我有个问题.我需要知道开放图层地图的实际缩放

$scope.refreshMap = function (lat, long) {
    map.setView(new ol.View({
        projection: 'EPSG:4326',
        center: [long, lat], 
        zoom: "here I do not know what to put"
    }));
};

我尝试map.getZoom()但它不起作用.logcat会让我失望

Uncaught TypeError: Object #<S> has no method 'getZoom'

我正在使用openlayers版本:v3.16.0

Answer 1

缩放是属性ol.View.所以ol.Map有一个ol.View缩放级别,中心,投影说一些.

map.getView().getZoom();
