clicktrack.php：php返回操作信息
<body>
<a href="http://www.111cn.net" onclick="dowork(this);" >test</a>
</body>
js代码
网页特效代码是有点多，但这里只dowork(),这个函数将处理鼠标的点击，获得源和目标位置，并调用clicktrack.php更新统计信息
function dowork(element){
httpobject = gethttpobject();
if (httpobject != null) {
dst = element.href;
src = document.location.href;
httpobject.open("get", "clicktrack.php?src="+src+"&dst="+dst, true); httpobject.send(null);
httpobject.onreadystatechange = setoutput;
}}
