Question

我使用的是supermap iserver for openlayers，query查询到的满足条件的地块会高亮显示，请问怎样设置高亮的透明度，让透明度动态变化逐渐变小？

您好           var resultLayer = new ol.layer.Vector({
                source: bufferSource,
                style: new ol.style.Style({
                    stroke: new ol.style.Stroke({
                        color: 'blue',
                        width: 1
                    }),
                    fill: new ol.style.Fill({
                        color: 'rgba(255, 0, 0, 1)'//a取值（0-1）可改透明度
                    })
                })
            });
