在何处添加可见性:在第一层代码中为false？
在何处添加可见性:在第一层代码中为false？
提问于 2011-10-08 15:33:53
我想知道在哪里可以在下面的代码中添加可见性: false：就像在第二段代码中一样？
var line_10 = new OpenLayers.Layer.GML("Line nr-10",
"lines/line_10.kml",
{
format: OpenLayers.Format.KML,
style: {strokeWidth: 4, strokeColor: "#f08080", fillOpacity: 1 },
projection: map.displayProjection
}
);第二部法典：
var linja4_2 = new OpenLayers.Layer.Vector("Line nr-4 stations", {
projection: map.displayProjection,
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url: "/data/linja-nr4.kml",
format: new OpenLayers.Format.KML({
extractStyles: true,
extractAttributes: true
})
}),
visibility: false

如果我没记错的话，我会把visibility放在这里：
var line_10 = new OpenLayers.Layer.GML("Line nr-10",
"lines/line_10.kml",
{
format: OpenLayers.Format.KML,
style: {strokeWidth: 4, strokeColor: "#f08080", fillOpacity: 1 },
projection: map.displayProjection
}, {
visibility: false
}
);或如评论中所建议的：
var line_10 = new OpenLayers.Layer.GML("Line nr-10",
"lines/line_10.kml",
{
format: OpenLayers.Format.KML,
style: {strokeWidth: 4, strokeColor: "#f08080", fillOpacity: 1 },
projection: map.displayProjection
}
);
line_10.setVisibility(false);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
