Question

当我将点击事件的事件监听器添加到标记后几分钟时，我有这个代码，我的浏览器不会响应或崩溃。但如果我删除事件监听器我的浏览器不会粉碎，我已经使用了闭包方法事件，但它仍然崩溃。有人帮助我。

提前谢谢。

var map;
var marker;
var markerarray =[];

           google.maps.event.addListener( marker, 'click', (function  (marker, con, infowindow) {
        return function () {

  });

我发现导致浏览器崩溃的原因，如果我点击循环中创建的最后一个标记，我的浏览器将崩溃。如果我点击第一个和第二个标记它工作正常我的浏览器不会崩溃。如果我点击它只是最后一个标记。我不知道如何解决这个问题

这是我将如何做到的。有一个功能可以将标记与infowindows相关联。

function bindInfoWindow(marker, map, infowindow, con) { 
    google.maps.event.addListener(marker, 'click', function() { 
        infowindow.setContent(con); 
        infowindow.open(map, marker); 
    }); 
}

从循环内调用该函数，而不是为每个标记定义相同的函数。

for (var i = 0; i < coordinates.length; i++) {
    ...
    bindInfoWindow(marker, map, infowindow, con);  
}

添加事件单击循环时，谷歌地图标记崩溃
