Javascript 事件

事件处理的发展:

<a href="index.html"  onclick="retrun infoWindow(this.href)">Index </a>

then 

HTML

<a href ="index.html" id="info">Index</a>

JavaScript:

 var triggerLink = document.getElementById('info');

triggerlink.onclick = infoWindow;

shortage:一次只能指派一个函数,一个脚步独占了一个元素的事件.

 

then 

var triggerLink =document.getElementById('info');

triggerLink.onclick = function(){

showInfoWindow(this.href);

hightlight(this);

setCurrent(this);

}

fuction showInfo(url){

}

shortage:网页问的的最后一个脚本会覆盖其它的脚本促发的事件.

last solution:

fuction addLoadEvent(func){
var oldonload = window.onload;

if(typeof window.onload != 'function'){

window.onload = func;

}else{

window.onload =function(){
oldonload();

func();

}

}

}
