如何通过弹出窗口防止功能点击？

Question

我需要在单击矢量图层的特征时打开一个弹出窗口。我用的是Vector Icon Example as starting point. My problem is that when a feature is covered by the popup, you can still click it (Fiddle-Demo：点击下面的点，你可以通过弹出窗口点击上面的点）。如何防止这种行为？

相关代码：

map.on('click', function(evt) {
    var element = popup.getElement();
    $(element).popover({
    "placement": "top",
    "html": true
}); 
var popover = $(element).data("bs.popover");
var feature = map.forEachFeatureAtPixel(evt.pixel, function(feature, layer) {
    return feature;
});
if (feature) {
    popup.setPosition(feature.getGeometry().getCoordinates());
    popover.options.content = feature.get("name");
    $(element).popover('show');
} else {
    $(element).popover('destroy');
}
});

Answer 1

将 stopEvent: true 设置为您的 ol.Overlay 对象，例如：

var popup = new ol.Overlay({
  element: element,
  positioning: 'bottom-center',
  stopEvent: true
});
