OpenLayers SelectFeature在幾個圖層上

我使用LayerSwitcher將幾個KML圖層（88）添加到OpenLayers地圖中。我已將所有圖層添加到SelectFeature控件。但是，一旦我使用OpenLayers.Map.addLayers向地圖添加超過77層的圖層，SelectFeature的onSelect函數就不會被調用。OpenLayers SelectFeature在幾個圖層上

它似乎與KML圖層沒有關係，因爲我可以從addLayers調用中刪除任何11個圖層，其餘圖層可以正常工作。注意：我不必從SelectFeature構造函數中刪除任何內容。

proprietaryMap.addLayers(
[ 
    BaseLayer, 
    SectionLayer, DistrictLayer, BoroughLayer, 
    Business, Hotel, Market, Restaurant, 
    Library, Museum, Theater, 
    PostSecondary, PrivateEarly, PrivateElementry, PrivateHigh, PrivateJunior, PrivateK8, PrivateK12,

proprietaryMap.addControl(selectControl); 
selectControl.activate();

@ alexdube77感謝您的幫助。你讓我指出了正確的方向。

在創建最小化版本時，我發現問題。我必須移動從Marker，Polyline和Label圖層到上面圖層之前的位置。這導致這些圖層被繪製在上面的圖層下方，並使KML圖層可點擊。我還必須添加以下代碼並在添加所有圖層以使標記可點擊後調用它：

function checkMarkerZIndex() { 
    var olDivs = document.querySelectorAll('.olLayerDiv'); 
    for (var i = 0; i < olDivs.length; i++) { 
    if (olDivs[i].id.indexOf('OpenLayers_Layer_Markers') > -1) 
    olDivs[i].style.zIndex = '2000'; 
    } 
}

如果您發佈了最小化版本的代碼，那將會更容易幫助您。首先閱讀如何minimize your code，然後您可以使用jsfiddle.net主持一個小演示。
