我有以下JS代码来制作Google地图标记,我也尝试在每个标记上设置infowindow但是通过我的代码infowindow不在这里打开是我的代码
for(i=0; i<GPS.length; i++)
{
var image = 'ico/no.png';
var infowindow = new google.maps.InfoWindow();
var ContentString = GPS[i].TITLE
markers[i] = new google.maps.Marker(
{
position: GPS[i].GPS,
map: map,
draggable:true,
icon:image,
title:GPS[i].TITLE
});
google.maps.event.addListener(markers[i], 'click', function() {
infowindow.setContent(ContentString);
infowindow.open(map,markers[i]);
});
}

如果我没弄错的话,看起来你在这里有封闭问题。

谷歌的这个简单代码将在地图上显示marker:
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
var myOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var contentString = '<div id="content">'+
'<div id="siteNotice">'+
'</div>'+
'<h2 id="firstHeading" class="firstHeading">Uluru</h2>'+
'<div id="bodyContent">'+
'<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large ' +
'sandstone rock formation in the southern part of the '+
'Northern Territory, central Australia. It lies 335 km (208 mi) '+
'south west of the nearest large town, Alice Springs; 450 km '+
'(280 mi) by road. Kata Tjuta and Uluru are the two major '+
'features of the Uluru - Kata Tjuta National Park. Uluru is '+
'sacred to the Pitjantjatjara and Yankunytjatjara, the '+
'Aboriginal people of the area. It has many springs, waterholes, '+
'rock caves and ancient paintings. Uluru is listed as a World '+

'</div>'+
'</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Uluru (Ayers Rock)"
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});

你必须确保实例化map对象,然后是contentString,然后是marker然后是infowindow对象,最后添加一个click侦听器。代码按顺序执行,因此在逻辑查看时必须有意义。希望能帮助到你。
