移动端点击事件被重复触发

SuperMap.Control.SelectFeature 被重复触发两次,点击feature一次,拖动屏幕又被触发一次;并且地图无法响应点击事件

您好,本地测试不会触发多次,请检查是否有注册多个控件。方便的话请附上关键代码,以便进一步排查。本地测试代码如下:

 function addData() {
        var polygon_data = [[-16, 30], [-16, 0], [50, 0], [50, 30]];
        var points = [];
        for (var i = 0, len = polygon_data.length; i < len; i++) {
            var point = new SuperMap.Geometry.Point(polygon_data[i][0], polygon_data[i][1]);
            points.push(point);
        }
        var linearRing = new SuperMap.Geometry.LinearRing(points);
        var polygon = new SuperMap.Geometry.Polygon([linearRing]);
        var polygon_feature = new SuperMap.Feature.Vector(polygon);
        vectorLayer.addFeatures([polygon_feature]);
        var selectFeature = new SuperMap.Control.SelectFeature(vectorLayer,
       {onSelect:onFeatureSelect});
   //map上添加控件
   map.addControl(selectFeature);
   //激活控件
   selectFeature.activate();
    }

    var count=0;
    function onFeatureSelect(feature) {
    count++;
     alert(count)
    }

您好,您这边使用的是Classic吗,我这边在移动端测试是没有重复触发的现象的,您可以参考我的测试代码:

你好,查看你的代码中是否添加了Control.Navigation控件,移除这个控件可解决地图无法响应点击的情况。另外SelectFeature控件触发两次,可在实例化该控件的时候设置repeat: false。

我确认试试,感谢
