Blog Behind GFW: Body.onload 关于页面加载完毕的问题

由于上午的Gmap没有调试成功，一直比较郁闷。
1、下午的时候收到K_Reverter的邮件他告诉我可以用window.onload=func的方法来代替Body.onload使用。
2、上网找了点资料，在360doc看到了一个老外关于window.onload的代码，也拿过来用下。
修改代码如下：

<script type="text/javascript" src="http://maps.google.com/maps?file=api&v=2&key=ABQIAAAA43IALmfadaZgVb1L-IEizRRKyzQqj4F9myd02mWX0DutlkqY_BQi03TATJA59RMvJYUa4fN7lK7X5g">
</script>

<div id="map" style="width: 600px; height: 400px;"></div>

<script type="text/javascript">
function init() {
if (GBrowserIsCompatible()) {
var map=new GMap(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
map.setMapType(G_HYBRID_TYPE);
map.centerAndZoom(new GPoint(121.5581,29.8394), 8);
// Create a base icon for all of our markers that specifies the
// shadow, icon dimensions, etc.
var baseIcon = new GIcon();
baseIcon.shadow = "http://www.google.com/mapfiles/shadow50.png";
baseIcon.iconSize = new GSize(20, 34);
baseIcon.shadowSize = new GSize(37, 34);
baseIcon.iconAnchor = new GPoint(9, 34);
baseIcon.infoWindowAnchor = new GPoint(9, 2);
baseIcon.infoShadowAnchor = new GPoint(18, 25);

// Create a lettered icon for this point using our icon class
var letter = String.fromCharCode("A".charCodeAt(0) + 25);
var icon = new GIcon(baseIcon);
icon.image = "http://www.google.com/mapfiles/marker" + letter + ".png";
var ningbo = new GMarker(new GPoint(121.5581,29.83941),icon);
GEvent.addListener(ningbo, "click", function(){
ningbo.openInfoWindowHtml("过几天出去溜达下！"); });
map.addOverlay(ningbo);

// Create a lettered icon for this point using our icon class
var letter = String.fromCharCode("A".charCodeAt(0) + 24);
var icon = new GIcon(baseIcon);
icon.image = "http://www.google.com/mapfiles/marker" + letter + ".png";
var zhoushan = new GMarker(new GPoint(122.1018,30.0207),icon);
GEvent.addListener(zhoushan, "click", function(){
zhoushan.openInfoWindowHtml("你说什么啊？我听不见呀！");
});
map.addOverlay(zhoushan);
}
};
