Question

我正在尝试点击地图上的功能信息点击openlayers3。我在控制台中收到类似TypeError的错误消息：layer.getSource（...）为null 我的点击功能是

 map.on('click', function (evt) {
    var fl = map.forEachFeatureAtPixel(evt.pixel, function (feature, layer) {
        return { 'feature': feature, 'layer': layer };
    });

    var feature = fl.feature;
    layer = fl.layer;
    if (layer == vectorlayer) {
        var admin = "<table>";
        admin += "<tr><td style='color:green; border: 0px solid red;text-align:left;vertical-align:middle;font-size:15px;'><b>  Information<b></td></tr>";
        admin += "<tr><td><b>Type</b></td><td>:</td><td >" + feature.get('field1') + "</td></tr>";
        admin += "<tr><td><b>District</b></td><td>:</td><td>" + feature.get('district') + "</td></tr>";
        admin += "<tr><td><b>Taluk</b></td><td>:</td><td >" + feature.get('taluk') + "</td></tr>";
        admin += "<tr><td><b>Village</b></td><td>:</td><td>" + feature.get('village') + "</td></tr>";
        admin += "<tr><td><b>code</b></td><td>:</td><td>" + feature.get('field2') + "</td></tr>";
        $("#Identifier").html(schooladmin);
        $("#Identifier").dialog('open');
        schooladmin += "</table>";
      }
});

这不是点击功能，它是指针移动功能，如果你想使用点击互动，你必须将catched事件更改为singleClick，如下所示：

map.on('singleclick', function(evt){
   //...
});

map.on click在openlayers3中不起作用
