使用心得
在使用了一次上面这段摘抄过来的代码后,发现有他的CloseDiv方法太简单,效果不统一,所以我做了如下修改:
function closeDiv()
{
if(objTimer) window.clearInterval(objTimer) //关闭后就不要调整DIV了
try
{
if(parseInt(document.getElementById("eMeng").style.top,10) <= (docHeight + parseInt(document.documentElement.scrollTop,10)))
{
divTop = parseInt(document.getElementById("eMeng").style.top,10)
document.getElementById("eMeng").style.top = divTop + 1
//objTimer = window.setInterval("closeDiv()",10)
setTimeout("closeDiv()",10); //加上这个就可以弹走了
}
else
{
document.getElementById('eMeng').style.visibility='hidden';
document.getElementById('eMeng').style.top = docHeight - divHeight;
}
}
catch(e){}
}
还有一个问题,在.NET中使用document.body.clientHeight时,值不是当前页面的可视高度,可以做下修改:
document.body.clientWidth-> document.documentElement.clientWidth
document.body.clientHeight -> document.documentElement.clientHeight
这个例子在传入参数和DIV的控制性上还可以优化.等相关应用尝试后在修改吧.
