Question

我只是想让用户点击地图来设置提醒但很简单，就像这样

google.maps.event.addListener(map, 'click', function() {
    alert("Ok");
    });

我从来没有收到警告“Ok”为什么。我在这里错过了什么？我想我已经删除了不必要的代码。

这里最相关的代码JS

var p = $("#map_search");
        var position = p.position();
        $("#directionsPanel").css({top: position.top, position:'absolute'});

                navigator.geolocation.getCurrentPosition(ShowPosition);
            }
            else {
                x.innerHTML = "Geolocation is not supported by this browser.";

根据documentation for GMaps，您需要将地图事件添加到GMap对象本身：

map = new GMaps({
  div: '#map',
  zoom: 16,
  lat: -12.043333,
  lng: -77.028333,
  click: function(e) {
    alert('click');
  },
  dragend: function(e) {
    alert('dragend');
  }
});
