带有Infowindows的Google Maps API多标记

I am trying to add multiple markers each with its own infowindow that comes up when clicked on. I am having trouble with getting the infowindows coming up, when I try it either shows up only one marker without an infowindow.

我正在尝试添加多个标记，每个标记都有自己的infowindow，点击时会出现。我遇到了让infowindows出现的问题，当我尝试它时，它只显示一个没有infowindow的标记。

Thanks, let me know if you need some more information

You could use a closure. Just modify your code like this:

你可以使用一个闭包。只需像这样修改你的代码：

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

Here is the DEMO

这是DEMO

Here is the code snippet which will work for sure. You can visit below link for working jsFiddle and explainantion in detail. How to locate multiple addresses on google maps with perfect zoom

这是代码片段，肯定会起作用。您可以访问以下链接，详细了解jsFiddle和explainantion。如何使用完美缩放功能在Google地图上找到多个地址

var infowindow = new google.maps.InfoWindow();  
google.maps.event.addListener(marker, 'mouseover', (function(marker) {  
           return function() {  
               var content = address;  
               infowindow.setContent(content);  
               infowindow.open(map, marker);  
           }  
         })(marker));

#3

If you also want to bind closing of infowindow to some event, try something like this

如果你还想将infowindow的关闭绑定到某个事件，请尝试这样的事情

google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
    return function() {
        infowindow.setContent(content);
        infowindow.open(map,marker);
        windows.push(infowindow)
        google.maps.event.addListener(map,'click', function(){ 
            infowindow.close();
        }); 
    };
})(marker,content,infowindow));

#4

function setMarkers(map,locations){

for (var i = 0; i < locations.length; i++)
 {  

 var loan = locations[i][0];
 var lat = locations[i][1];
 var long = locations[i][2];
 var add =  locations[i][3];

 latlngset = new google.maps.LatLng(lat, long);

 var marker = new google.maps.Marker({  
          map: map, title: loan , position: latlngset  
 });
 map.setCenter(marker.getPosition());


 marker.content = "<h3>Loan Number: " + loan +  '</h3>' + "Address: " + add;


 google.maps.events.addListener(marker,'click', function(map,marker){
          map.infowindow.setContent(marker.content);
          map.infowindow.open(map,marker);

 });

 }
}

Then move var infowindow = new google.maps.InfoWindow() to the initialize() function:

然后将var infowindow = new google.maps.InfoWindow（）移动到initialize（）函数：

function initialize() {

    var myOptions = {
      center: new google.maps.LatLng(33.890542, 151.274856),
      zoom: 8,
      mapTypeId: google.maps.MapTypeId.ROADMAP

    };
    var map = new google.maps.Map(document.getElementById("default"),
        myOptions);
    map.infowindow = new google.maps.InfoWindow();

    setMarkers(map,locations)

  }
