1。通过元素ID获取相关信息
document.getElementById('MyFile').display="None";//===============设为隐藏
2。在aspx页面中写Js要注意写法，这样写：
Response.Write("<script language=\"javascript\">\r\n");
Response.Write("window.returnValue =\""+FileStr+"\";\r\n");
Response.Write("close();\r\n");
Response.Write("<");
Response.Write("/");
Response.Write("script>\r\n");
此写法，最后所得的值将返回父窗口!
3。在某个元素的后面加入新的元素的写法
var str = '<br><INPUT type="file" size="50" NAME="File">' ;
document.getElementById('MyFile').insertAdjacentHTML("beforeEnd",str) ;
不间断连续滚动的图片效果(向左滚动)
<!-- 把下列代码加到<body>区域内 -->
<base href="http://www.webjx.com">
<div id=demo style=overflow:hidden;height:33;width:200;background:#214984;color:#ffffff>
<table align=left cellpadding=0 cellspace=0 border=0>
<tr>
<td id=demo1 valign=top><img src="/img/link.gif"><img src="/img/link1.gif"><img src="/img/link2.gif"><img src="/img/link3.gif">
</td>
<td id=demo2 valign=top></td>
</tr>
</table>
</div>
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{
demo.scrollLeft++
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>
向上滚动的无间缝文字[已经测试,可以使用]
<script>
var speed=20
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetTop-demo.scrollTop<=0)
demo.scrollTop-=demo1.offsetHeight
else{
demo.scrollTop++
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>
左右2个按钮控制文字左右滚动
<script>
function mov(direction) {
tw=test.document.body;
d=direction;
aa=setInterval("if((tw.scrollLeft+tw.clientWidth<tw.scrollWidth)||(tw.scrollLeft>0)) { test.scrollBy(d,0)} else{clearInterval(aa)}",10);
}
</script>
<center>
<a href="####" onmouseover="mov(-3)" onmouseout="clearInterval(aa)" onmousedown="clearInterval(aa);mov(-6)" onmouseup="clearInterval(aa);mov(-3)"><<</a>
<a href="####" onmouseover="mov(3)" onmouseout="clearInterval(aa)" onmousedown="clearInterval(aa);mov(6)" onmouseup="clearInterval(aa);mov(3)">>></a>

关于获取主机IP和主机名
//得到主机IP
string hostIp = Request.ServerVariables["REMOTE_ADDR"];
//得到主机名hostName
System.Net.IPAddress address = System.Net.IPAddress.Parse(hostIp);
System.Net.IPHostEntry ipInfor = System.Net.Dns.GetHostByAddress(address);
string hostName = ipInfor.HostName;
关于等比例缩小图片
在img属性加入 onload='javascript:DrawImage(this,158,158);'
将下面定为一个js文件
var flag=false;
function DrawImage(ImgD,kw,kh)
{
var image=new Image();
image.src=ImgD.src;
if(image.width>0 && image.height>0)
{
flag=true;
if(image.height/image.width<=1)//说明宽》高＝＝》以宽为标准
{
if(image.width>kw)
{
ImgD.width=kw;
ImgD.height=(image.height*kw)/image.width;
}
else
{
ImgD.width=image.width;
ImgD.height=image.height;
}
}
else//以高为标准
{
if(image.height>kh)
{
ImgD.height=kh;
ImgD.width=(image.width*kh)/image.height;
}
else
{
ImgD.width=image.width;
ImgD.height=image.height;
}
}
}
}
不间断连续滚动的图片效果(向上滚动)
<!-- 把下列代码加到<body>区域内 -->

Js更改下拉菜单后弹出新窗口连接到别的网站
<SCRIPT language=javascript>
function goFamily(url)
{
if(url!="") window.open(url)
}
</SCRIPT>
<SELECT class=site onchange=goFamily(this.options[this.selectedIndex].value)>
