但我想要这个:

我不知道这是否有帮助，但我发现您要使用的方法不起作用。我能够在 javascript 中以编程方式设置它。这使您可以在自己创建的红圈图标上方添加一个标签。

希望这对您有所帮助!

javascript(减去构建 map 对象等的其他代码):

function addLayer(){    
    var myStyles = new OpenLayers.StyleMap({ 
    "default": new OpenLayers.Style({ 
        strokeColor: "#FFCC33", 
        strokeWidth:10, 
        strokeOpacity:1, 
        fillColor:"#003399", 
        fillOpacity: 1, 
        externalGraphic: "icons/redcircle.png",
        labelYOffset: 15,
        pointRadius: 5,
        label:"${label}",                   
    })
});

currentLayer = new OpenLayers.Layer.Vector("KML", {
    styleMap: myStyles,
    projection: map.displayProjection,      
    strategies: [new OpenLayers.Strategy.Fixed()],          
    protocol: new OpenLayers.Protocol.HTTP({
        url: "/kml/mymap.kml",
        format: new OpenLayers.Format.KML({
            extractStyles: true,
            extractAttributes: true             
        })          
    })          
});
