I've been having problems with the infoWindows and Google Maps API v3. Initially, I've ran into the problem that everyone else has of closing infoWindows when opening a new one. I thought to have solved the problem by defining "infowindow" beforehand. Now they close when I click on a new marker, but the content is the same. How should I re-structure my code to make sure the content is the right one each time - and only one infoWindow is open at a given time?

Thank you!

var allLatLngs = new Array();
var last = 0;
var infowindow;

function displayResults(start, count){
    if(start === undefined){
        start = last;
    }
    if(count === undefined){
        count = 20;
    }
    jQuery.each(jsresults, function(index, value) {
        if(index >= start && index < start+count){
            var obj = jQuery.parseJSON(value);
        $("#textresults").append(index + ": <strong>" + obj.name + "</strong> " + Math.round(obj.distanz*100)/100 + " km entfernt" + "<br/>");

            var myLatlng = new google.maps.LatLng(obj.geo_lat, obj.geo_lon);
            allLatLngs.push(myLatlng);

        var contentString = '<strong>'+obj.name+'</strong>';

        infowindow = new google.maps.InfoWindow({
            content: contentString
        });


            var marker = new google.maps.Marker({
                  position: myLatlng,
                  //title:"Hello World!"
              });
            marker.setMap(map);

            google.maps.event.addListener(marker, 'click', function() {
            if (infowindow) { infowindow.close(map,marker); }
              infowindow.open(map,marker);
            });
        }
    });

    last = start+count;

你在打电话

infowindow.open(map,marker);

在 jQuery.each 迭代中，因此，我认为它将调用迭代中的最后一项。修改您的代码，以便在 jQuery.each 迭代中得到它。

var curItem = 1;   
google.maps.event.addListener(aMarker, "click", function(idx, theContent) {
   return function() {
       alert(idx);  //Should print 1 marker1, 2 for marker 2, to show it's ok.

       //Your stuff...
       if (infowindow) { 
          infowindow.close(map,marker); 
       }       
       infowindow.setContent(theContent);  
       infowindow.open(map,marker);
   }
} (curItem++, contentString)
);

当您看到“返回函数（）”时，我正在使用javascript 闭包。我刚刚将这个闭包用于其他东西。我在之前的答案中已经摆脱了其他之前的变化。
