Question

点击某一标注面，对应的面清除掉

Answer 1

你好，你这边只是删除面对吧， map.removeLayer(polygon)可以清空polygon这个面。

let newListData = [

        'points': [

// 创建
featuresLayer = new SuperMap.Layer.Vector("featuresLayer");

newListData.map(item => {
    for (let key in item) {
        var points = [];
        var lineVector;
        if (key === 'points'){
            item[key].map(val => {
                points.push(new SuperMap.Geometry.Point(val['x'],val['y'])); // 创建点
            });
        }
        lineVector = new SuperMap.Feature.Vector(new SuperMap.Geometry.LinearRing(points));
        lineVector.style={
            strokeColor: "#f00",
            strokeWidth: 1,
            fill: true,             // 是否填充中间 默认true：为填充
            label: '030',           // 图形中心内容
            fontColor: '#fff',
            fillColor: "#ff0",
            fillOpacity: "0.5",
            content: item['content']
        };
        featuresLayer.addFeatures(lineVector);
        //  添加移入事件
        selectDrawFeature = new SuperMap.Control.SelectFeature(featuresLayer, {
            onSelect: openWindow,
            onUnselect: unfeatueSelect,
            hover:true
        });

我用 map.removeLayer(featuresLayer)会把页面上的所有面全部删除掉，如何只删除指定的一个呢？？？？
