我複選框不顯示功能層

這裏是我的代碼我複選框不顯示功能層

else if(which == "abc"){ 
     var d = (id).toString(); 
     d = d.replace("abc", ""); 
     query.where = "Name='" + d + "'"; 
     console.info(query.where); 
     query.returnGeometry = true; 
     layerC.selectFeatures(query, FeatureLayer.SELECTION_NEW, function (features) { 
      thePoly = features[0].geometry; 
      theExtent = thePoly.getExtent().expand(1); //Zoom out slightly from the polygon's extent 
      map.setExtent(theExtent); 
     }); 

    } 
    var text; 
    var R = document.getElementById('abc').value; 
    var rLyrToggle = dom.byId("rLyr"); 

    switch(Cpt) { 
case "room1": 
    on(rLyrToggle, "change", function() { 
     building layer.visible = rLyrToggle.checked; 

    }); 
    break; 

default: 
    text = "No room"; 
}

我的複選框，在檢查圖層添加到地圖上沒有顯示層，但我禁用其公開程度，我想，當COMBOX選擇的值等於所述殼體1，則特徵是看得到當用戶選中複選框

你可以創建一個的jsfiddle，我們可以重現相同的問題..這將是一個更好的方式...但是，在某些地方它的腥在開關情況下..建設layer.visible = rLyrToggle.checked;在這一行...如果你想要一個確切的修復，然後添加一些更多的細節或類似的運行環境.. –

腥嗎？我添加了圖層到地圖，但將其可見性設置爲false。當combox值匹配具有該文件的案例編號時，所以當用戶單擊複選框時，所述圖層可見 –

或者是否存在用戶從下拉列表中選擇圖層的任何示例按鈕。它是級聯嵌套過濾 –

那麼，找到所有的值（如在評論提到的）從GIS層我建議使用queryTask代替esriRequest -

下面是工作代碼 -

謝謝:)它幫助了很多。 –

很高興爲您效勞...... –

如果我想從屬性表中返回文本值並在comobo框中填充這些值。那麼它是如何完成的> –
