事件侦听器为InfoBubble "closeclick“。怎么安排的？

Question

如何为关闭InfoBubble的事件设置侦听器？我正在使用GoogleMap API v.3和编译的信息泡脚本。它不起作用：

infoBubble = new InfoBubble({
  maxWidth: 500
});

infoBubble.open(map, marker);

google.maps.event.addListenerOnce(bubble, 'domready', function(){ 
   google.maps.event.addDomListener(infoBubble, 'close', function() {  
      alert("Closed");
   }); 
}); 

找到了解决办法。这是平庸的。坏消息还没有记录下来。必须学习反编译代码。

        google.maps.event.addListener(infoBubble, 'closeclick', function(){
            console.info("I'm Closed");
        });

Answer 1

不需要使用addListener关闭打开的InfoBubble。(在许多情况下可能对您有所帮助，但对于简单的应用程序，我们不需要它)

只需使用close方法，就像使用open方法来打开infoBubble。

示例:

用于打开InfoBubble (您知道)

var infoBubble = new InfoBubble({
  maxWidth: 500
});

用于关闭InfoBubble

infoBubble.close();

function createMarker(point, mOptions, mType, html1, html2, pointX, units) {

    /** -------------
    *     Variable  
    **/

    var Title   = mOptions.title;
    var Name    = mOptions.name;
    var Mode    = mOptions.mode;
    var MiniMode= mOptions.mini;
    var User_id = mOptions.user;
    var id = mOptions.id;

    markersOptions.push(id);
    markersOptions[id] = {avatar: ''};

    if(!Mode){
        var Author = mOptions.author;
        var Event_id = mOptions.event;
        var Picture = mOptions.pic;
        var add_form  = create_adcomm_form(2, Event_id);
        var add_foto  = create_adfoto_form(2, Event_id);
        var comm_header = create_comm_head(Event_id);
        var links_block = create_links(Event_id);
    }   

    /** --------------------

    var marker = new google.maps.Marker({
