Google Map 事件包括：用户事件和MVC状态更改；实现Google Map事件需要为这些事件注册Javascript事件侦听器，并通过 google.maps.event.addListener()事件处理程序接收这些事件时执行相应代码。
常用的用户事件包括：click,dblclick,mouseup,mousedown,mouseover,mouseout；
MVC状态更改包括：zoom_changed
google.maps.event.addListener()方法有三个参数，一个对象，一个待侦听事件以及一个指定事件发生时调用的函数。
<script type=”text/javascript”>
$(function () {
var XiningLatlng = new google.maps.LatLng(36.619494, 101.80427);
var options = {
zoom: 13,
center: XiningLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map($(“#map”)[0], options);
google.maps.event.addListener(map, ‘zoom_changed’, function () {
setTimeout(moveToDarwin, 3000);
});
var marker = new google.maps.Marker({
position: XiningLatlng,
map: map,
title: “Hello Xining!”
});
google.maps.event.addListener(marker, ‘click’, function () {
map.setZoom(15);
});
})
function moveToDarwin() {
var DarwinLatlng = new google.maps.LatLng(-12.461334, 130.841904);
map.setCenter(DarwinLatlng);
}
</script>
Demo 2
<script type=”text/javascript”>
var map;
var infowindow;
var zoomLevel;
$(function () {
var myLatlng = new google.maps.LatLng(-25.363882, 131.044922);
var options = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map($(“#map”)[0], options);
infowindow = new google.maps.InfoWindow({
content: ‘zoom level test’,
size: new google.maps.Size(50, 50),
position: myLatlng
});
infowindow.open(map);
google.maps.event.addListener(map, ‘zoom_changed’, function () {
zoomLevel = map.getZoom();
infowindow.setContent(“zoom:” + zoomLevel);
if (zoomLevel == 0)
map.setZoom(10);
})
})
</script>
