形式在觀衆的OpenLayers

Question

您好所有，我創建的OpenLayers瀏覽器中的窗體，部署在同樣的方式，切換地圖。

我覺得OP想做的事，是通過類似於在默認訪問鷹眼/ LayerSwitcher一個按鈕來訪問他的自定義窗體的OpenLayers。

如何做到這一點可以從如何鷹眼控制*實現提取：

this.div.className += " " + this.displayClass + 'Container'; 
var imgLocation = OpenLayers.Util.getImagesLocation(); 
// maximize button div 
var img = imgLocation + 'layer-switcher-maximize.png'; 
this.maximizeDiv = OpenLayers.Util.createAlphaImageDiv(
         this.displayClass + 'MaximizeButton', 
         null, 
         new OpenLayers.Size(18,18), 
         img, 
         'absolute'); 
this.maximizeDiv.style.display = 'none'; 
this.maximizeDiv.className = this.displayClass + 'MaximizeButton'; 
OpenLayers.Event.observe(this.maximizeDiv, 'click', 
         OpenLayers.Function.bindAsEventListener(this.maximizeControl, 
                   this) 
); 
this.div.appendChild(this.maximizeDiv); 

// minimize button div 
var img = imgLocation + 'layer-switcher-minimize.png'; 
this.minimizeDiv = OpenLayers.Util.createAlphaImageDiv(
         'OpenLayers_Control_minimizeDiv', 
         null, 
         new OpenLayers.Size(18,18), 
         img, 
         'absolute'); 
this.minimizeDiv.style.display = 'none'; 
this.minimizeDiv.className = this.displayClass + 'MinimizeButton'; 
OpenLayers.Event.observe(this.minimizeDiv, 'click', 
OpenLayers.Function.bindAsEventListener(this.minimizeControl, 
             this) 
); 
this.div.appendChild(this.minimizeDiv); 

var eventsToStop = ['dblclick','mousedown']; 

for (var i=0, len=eventsToStop.length; i<len; i++) { 
    OpenLayers.Event.observe(this.maximizeDiv, 
          eventsToStop[i], 
          OpenLayers.Event.stop); 

    OpenLayers.Event.observe(this.minimizeDiv, 
          eventsToStop[i], 
          OpenLayers.Event.stop); 
}

插入並修改這個，可以用來創建我認爲你正在尋找的效果。

祝你好運！
