我想知道如何使用openlayers使wms层透明

每个不透明层的当前javascript如下所示：

var lyr_GDPSETAAirtemperatureC = new ol.layer.Tile({
                        source: new ol.source.TileWMS(({
                          url: "http://weatherservice",
                          params: {"LAYERS": "GDPS.ETA_TT", "TILED": "true"},
                        })),
                        title: "Air temperature (°C)"
对于
ol.layer.Tile
可以设置其
opacity
使其透明

new ol.layer.Tile({
                    opacity: 0.5,
                    visible: true,
                    source: new ol.source.TileWMS(({
                      url: "http://weatherservice",
                      params: {"LAYERS": "GDPS.ETA_TT", "TILED": "true"},
                    }))
或者使用
visible:false将其全部隐藏起来
