我使用自定义OpenLayers控件来更改功能上图标的样式。它看起来像这样:

StyleFeature = OpenLayers.Class(OpenLayers.Control, {
    layer = null,
    style = null,
    initialize: function (layer, style, options) {
        OpenLayers.Control.prototype.initialize.apply(this, [options]);
        this.layer = layer;
        this.style = style;
    },
    activate: function() {
        this.layer.styleMap.styles["default"] = this.style;
        this.layer.styleMap.styles["temporary"] = this.style;
        this.layer.styleMap.styles["select"] = this.style;
        return OpenLayers.Control.prototype.activate.apply(this, arguments);
    },
    CLASS_NAME: "OpenLayers.Control.StyleFeature"
});

这很好用,但是我想从我传入的样式中使用externalGraphic来在OpenLayers控件本身上放置一个图像标记。我目前唯一的造型选择似乎是通过CSS。

有什么想法吗?
