Question

我无法执行当有人点击infoWindow div上的编辑，共享或删除时调用的jQuery函数。

var markers = [];
for(i=0; i<array.length; ++i) {
  var marker = new google.maps.Marker({
    position: {lat: parseFloat(array[i]['latitude']), lng: parseFloat(array[i]['longitude'])},
    map: map
  });

  var id = array[i]['id'];
  var edit = 'edit', share = 'share', del = 'delete';
  var cString = '<div style="margin: auto; text-align: center; font-family: Tahoma, Geneva, sans-serif;"><strong>Location Name: </strong>' + array[i]['title']
  + '<br><strong>Location Description: </strong>' + array[i]['description']
  + '<br><br><br><div class="btn-group"><button type="button" class="btn btn-primary '+edit+'" id="' + id + '">Edit</button><button type="button" class="btn btn-primary '+share+'" id="' + id + '">Share</button><button type="button" class="btn btn-primary '+del+'" id="' + id + '">Delete</button></div>';

  contentString.push(cString);
  google.maps.event.addListener(marker, 'click', (function(marker, i) {
    return function() {
      infoWindow.setContent(contentString[i]);
      infoWindow.open(map, marker);
    }
  })(marker, i));

  // this is the function
  $('button').click(function() {
    console.log('clicked');
  });

  markers.push(marker);
}

对于分配给infoWindow的按钮，它不会显示已点击的内容，但会显示其他按钮，例如注销，查看个人资料等。

Array是一个具有以下结构的JSON数组：

[
  {
    id:"1"
    description:"I am Loving It! ↵McArabia Combo Meal: 520 Rs/-"
    latitude:"25.28919345"
    longitude:"67.11113134"
    title:"McDonalds"
    type:"favourite"
  },//....
  //......
]

我该如何解决这个问题？

Answer 1

您在页面加载后动态添加这些按钮。您需要使用.on()函数在按钮上附加click事件。

$(document).on( "click", "button", function() {
  console.log('clicked');
});

并且不要在for循环中添加此事件绑定。把它放在文件准备好了。这仅用于基本信息，请按this link了解有关on()的更多信息以及如何使用正确的选择器/容器。

进一步@anu评论：

这是因为infoWindow仅在函数infoWindow.open(map, marker);中添加到DOM，所以当您将click绑定到按钮时，infoWindow的按钮不包括在内

和实例：

$(document).on('click', '.info-button', function(){
  alert('button clicked');
});
