Question

我有一个包含多个图层（A，B，C，D，E，F）的OpenLayers地图。我需要能够选择不同图层上的项目并与它们进行交互。目前我只能选择F层，而其他层阻止我在B层选择。

我创建了图层......

var Fields = new OpenLayers.Layer.Vector();
var Text = new OpenLayers.Layer.Vector();

将图层添加到我的地图

map.addLayers([Text, ZipCode, Legal, Fields, FieldLabels]);

调用我创建的高亮显示功能，因为功能正在添加到地图中...

    function HighLighText(ID) {
    //var mySelectStyle = OpenLayers.Util.extend({}, OpenLayers.Feature.Vector.style["default"]);
    //OpenLayers.Util.extend(mySelectStyle, { fillColor: "#f6b721", fillOpacity: 1 });

    mySelectStyle[ID] = OpenLayers.Util.extend({}, OpenLayers.Feature.Vector.style["default"]);
    OpenLayers.Util.extend(mySelectStyle, { fontColor: "#F6FF00", fillOpacity: .6 });
    mySelectStyle[ID].fontColor = "#F6FF00";
    mySelectStyle[ID].fillOpacity = .6;
    mySelectStyle[ID].label = String(ID);


    var txtReport = function (e) { OpenLayers.Console.log(e.type, e.feature.id); };
    highlightTextCtrl[ID] = new OpenLayers.Control.SelectFeature(Fields[ID], {
        hover: true,
        highlightOnly: true,
        renderIntent: "temporary",
        selectStyle: mySelectStyle[ID]


    });



    map.addControl(highlightTextCtrl[ID]);    
    highlightTextCtrl[ID].activate();

};

只要我隐藏上面的图层，上面的功能就很有效......如何在不隐藏图层的情况下完成这项工作？
