如何在 Openlayers 中禁用圖層

Question

我在 LayerSwitcher 中有一些層。我想顯示它們，但我想禁用其中一個，我的意思是它必須在 layerSwitcher 中可見，但您將無法與之交互。 這是我的 LayerSwitcher：例如，我想在黃色圖層上禁用。 這是我添加圖層的代碼的一部分

    stationsLayer = new ol.layer.Vector({
        source: stationsSource,
        visible: true,
        title: "Estaciones",
        style: styleFunction,
    });
    tiffRaster = new ol.layer.Image({
        title: 'PGA(gal)',
        // extent: [-180, -90, -180, 90],
        source: new ol.source.ImageWMS({
            url: 'http://url/geoserver/faml/wms',
            params: {
                'LAYERS': 'faml:' + f
            },
            ratio: 1,
            serverType: 'geoserver'
        })
    });

    map.addLayer(tiffRaster);
    map.addLayer(stationsLayer);

 var osmLayer = new ol.layer.Tile({ source: new ol.source.OSM(), title: "OSM" }); var stamenLayer = new ol.layer.Tile({ source: new ol.source.Stamen({ layer: "terrain", maxZoom: 18 }), visible: false, title: "Stamen" }); var baseLayerGroup = new ol.layer.Group({ layers: [osmLayer, stamenLayer] }) var map = new ol.Map({ target: document.getElementById("map"), view: new ol.View({ center: ol.proj.fromLonLat([8, 50]), zoom: 5 }) }); map.setLayerGroup(baseLayerGroup); const radioButtons = getAllRadioButtons(); for (var i = 0; i < radioButtons.length; i++) { radioButtons[i].addEventListener("change", function(e) { var target = e.currentTarget; baseLayerGroup.getLayers().forEach(function(layer) { layer.setVisible(layer.get("title") === target.value); }); }); } function getAllRadioButtons() { var arrInput = document.getElementsByTagName("input") var arrRadio = []; var j = 0; for (var i = 0; i < arrInput.length; i++) { if (arrInput[i].type == "radio") { arrRadio[j] = arrInput[i]; j++; } } return arrRadio; }

tiffRaster.setVisible(false)

和

tiffRaster.setVisible(true)

應該這樣做。
