Question

我使用OpenLayer加载KML。加载图标，但不显示标签。如果我删除＆＃34; Style＆＃34;部分显示标签，但不显示图标。任何想法都非常感谢。感谢

我的代码：

    var myStyles2 = new OpenLayers.StyleMap({
        "default": new OpenLayers.Style({
            strokeColor: "#FFCC33",
            strokeWidth: 6,
            strokeOpacity: 1,
            fillColor: "#003399",
            fillOpacity: 0,
            label: "${name}",
            fontSize: "40px"
        })
    });

    var OMapShips = new OpenLayers.Layer.Vector("KML", { styleMap: myStyles2,
        projection: new OpenLayers.Projection("EPSG:4326"),
        strategies: [new OpenLayers.Strategy.Fixed({ preload: false })],
        protocol: new OpenLayers.Protocol.HTTP({
            url: 'js/hl/XMLFile.xml',
            format: new OpenLayers.Format.KML({
                extractStyles: true,
                extractAttributes: true,
                maxDepth: 2
            })
        }),
        renderers: ["SVG"]
    });

    OMap.addLayers([OMapShips]);

我发现了。我刚刚从我的KML中取出了整个“Style”部分，让OpenLayers处理图标和标签绘制。即使我实现了轮换！我希望这对任何人都有帮助。如果有用，请不要忘记标记为答案，并提出问题。

JavaScript代码：

    var myStyles2 = new OpenLayers.StyleMap({ 'default': {
        strokeColor: "#00FF00",
        strokeOpacity: 1,
        strokeWidth: 1,
        fillColor: "#005500",
        fillOpacity: 0.5,
        pointRadius: 10,
        pointerEvents: "visiblePainted",
        // label with \n linebreaks
        label: "${name}",

        fontColor: "#000000",
        fontSize: "12px",
        fontFamily: "Courier New, monospace",
        fontWeight: "bold",
        labelAlign: "${align}",
        labelXOffset: "${xOffset}",
        labelYOffset: +18,
        labelOutlineColor: "white",
        labelOutlineWidth: 3,
        externalGraphic: "${myurl}",
        rotation: "${myheading}"
        }
    });
