在Google Maps 上点击标签显示说明并保持不消失
JS如下：
(function() {
window.onload = function() {
// Creating an object literal containing the properties
// we want to pass to the map
var options = {
zoom: 3,
center: new google.maps.LatLng(37.09, -95.71),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
// Creating the map
var map = new google.maps.Map(document.getElementById('map'), options);
// Creating an array that will contain the coordinates
// for New York, San Francisco, and Seattle
var places = [];
// Adding a LatLng object for each city
places.push(new google.maps.LatLng(40.756, -73.986));
places.push(new google.maps.LatLng(37.775, -122.419));
places.push(new google.maps.LatLng(47.620, -122.347));
// Looping through the places array
for (var i = 0; i < places.length; i++) {
// Adding the marker as usual
var marker = new google.maps.Marker({
position: places[i],
map: map,
title: 'Place number ' + i
});
// Wrapping the event listener inside an anonymous function
// that we immediately invoke and passes the variable i to.
(function(i, marker) {
// Creating the event listener. It now has access to the values of
// i and marker as they were during its creation
google.maps.event.addListener(marker, 'click', function() {
var infowindow = new google.maps.InfoWindow({
content: 'Place number ' + i
});
infowindow.open(map, marker);
});
})(i, marker);
}
}
})();
CSS如下：
body {
font-family: Verdana, Geneva, Arial, Helvetica, sans-serif;
font-size: small;
background: #fff;
}
#map {
width: 100%;
height: 500px;
border: 1px solid #000;
}
.info {
width: 250px;
}
HTML如下：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>My first map</title>
<link type="text/css" href="css/style.css" rel="stylesheet" media="all" />
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript" src="js/map.js"></script>
</head>
<body>
<h1>My first map</h1>
<div id="map"></div>

效果如下：
