具有多个可点击图标" 如果我单击并打开弹出窗口， 然后，如果我单击地图(而不是图标)，弹出窗口消失了，好吧！ 但是如果我在第一个图标上打开了一个弹出框，然后单击另一个图标，气球将在下一个图标上移，但是内容不会更改...

我错了！！谢谢

推荐答案

在创建新弹出窗口之前，您需要销毁旧弹出窗口.但是销毁后立即重新创建可能存在问题，请参见 Bootstrap popover销毁&重新创建仅每隔第二次起作用，因此您可能需要短暂的超时，并且示例中相关代码的更新看起来像

You need to destroy the old popup before creating a new one. But there may be a problem with destroy followed immediately by recreate, see Bootstrap popover destroy & recreate works only every second time so you may need a short timeout and the update to the relevant code in the example would look like

    if (feature) {
      $(element).popover('destroy');
      setTimeout(function () {
        var coordinates = feature.getGeometry().getCoordinates();
        popup.setPosition(coordinates);
        $(element).popover({
          'placement': 'top',
          'html': true,
          'content': feature.get('name')
        });
        $(element).popover('show');
      }, 200);
    } else {
      $(element).popover('destroy');
    }
