复制代码 代码如下:
var eventutil = {
addhandler: function (element, type, handler) {
if (element.addeventlistener) {
element.addeventlistener(type, handler, false);
} else if (element.attachevent) {
element.attachevent(on + type, handler);
} else {
element[on + type] = handler;
}
},
removehandler: function (element, type, handler) {
if (element.removeeventlistener) {
element.removeeventlistener(type, handler, false);
} else if (element.detachevent) {
element.detachevent(on + type, handler);
} else {
element[on + type] = null;
}
}
};
var dom = document.createelement('img');
dom.style = 'display:none;';
dom.src = 'http://www.baidu.com/img/bdlogo.gif';
dom.id = 'map_img';
eventutil.addhandler(dom, 'error', function(){
alert('你的电脑没有链接网络，连接上网络后才能打开地图！');
});
document.body.appendchild(dom);
