画图:
<OBJECT
id=S
style="LEFT: 0px; WIDTH: 392px; TOP: 0px; HEIGHT: 240px"
height=240
width=392
classid="clsid:
</OBJECT>
<SCRIPT>
S.DrawingSurface.ArcDegrees(0,0,0,30,50,60);
S.DrawingSurface.ArcRadians(30,0,0,30,50,60);
S.DrawingSurface.Line(10,10,100,100);
</SCRIPT>
写注册表：
<SCRIPT>
var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.RegWrite ("HKCU\\Software\\ACME\\FortuneTeller\\", 1, "REG_BINARY");
WshShell.RegWrite ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader", "Goocher!", "REG_SZ");
var bKey = WshShell.RegRead ("HKCU\\Software\\ACME\\FortuneTeller\\");
WScript.Echo (WshShell.RegRead ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader"));
WshShell.RegDelete ("HKCU\\Software\\ACME\\FortuneTeller\\MindReader");
WshShell.RegDelete ("HKCU\\Software\\ACME\\FortuneTeller\\");
WshShell.RegDelete ("HKCU\\Software\\ACME\\");
</SCRIPT>
TABLAE相关(客户端动态增加行列）
<HTML>
<SCRIPT LANGUAGE="JScript">
function numberCells() {
var count=0;
for (i=0; i < document.all.mytable.rows.length; i++) {
for (j=0; j < document.all.mytable.rows(i).cells.length; j++) {
document.all.mytable.rows(i).cells(j).innerText = count;
count++;
}
}
}
</SCRIPT>
<BODY onload="numberCells()">
<TABLE id=mytable border=1>
<TR><TH> </TH><TH> </TH><TH> </TH><TH> </TH></TR>
<TR><TD> </TD><TD> </TD><TD> </TD><TD> </TD></TR>
<TR><TD> </TD><TD> </TD><TD> </TD><TD> </TD></TR>
</TABLE>
</BODY>
</HTML>
１．身份证严格验证：
<script>
var aCity={11:"北京",12:"天津",13:"河北",14:"山西",15:"内蒙古",21:"辽宁",22:"吉林",23:"黑龙江",31:"上海",32:"江苏",33:"浙江",34:"安徽",35:"福建",36:"江西",37:"山东",41:"河南",42:"湖北",43:"湖南",44:"广东",45:"广西",46:"海南",50:"重庆",51:"四川",52:"贵州",53:"云南",54:"西藏",61:"陕西",62:"甘肃",63:"青海",64:"宁夏",65:"新疆",71:"台湾",81:"香港",82:"澳门",91:"国外"}
function cidInfo(sId){
var iSum=0
var info=""
if(!/^\d{17}(\d|x)$/i.test(sId))return false;
sId=sId.replace(/x$/i,"a");
if(aCity[parseInt(sId.substr(0,2))]==null)return "Error:非法地区";
sBirthday=sId.substr(6,4)+"-"+Number(sId.substr(10,2))+"-"+Number(sId.substr(12,2));
var d=new Date(sBirthday.replace(/-/g,"/"))
if(sBirthday!=(d.getFullYear()+"-"+ (d.getMonth()+1) + "-" + d.getDate()))return "Error:非法生日";
for(var i = 17;i>=0;i --) iSum += (Math.pow(2,i) % 11) * parseInt(sId.charAt(17 - i),11)
if(iSum%11!=1)return "Error:非法证号";
return aCity[parseInt(sId.substr(0,2))]+","+sBirthday+","+(sId.substr(16,1)%2?"男":"女")
}
document.write(cidInfo("380524198002300016"),"<br/>");
document.write(cidInfo("340524198002300019"),"<br/>")
document.write(cidInfo("340524197711111111"),"<br/>")
document.write(cidInfo("34052419800101001x"),"<br/>");
</script>
２．验证ＩＰ地址
<SCRIPT LANGUAGE="JavaScript">
function isip(s){
var check=function(v){try{return (v<=255 && v>=0)}catch(x){return false}};
var re=s.split(".")
return (re.length==4)?(check(re[0]) && check(re[1]) && check(re[2]) && check(re[3])):false
}
var s="202.197.78.129";
alert(isip(s))
</SCRIPT>
３．加sp1后还能用的无边框窗口！！
<HTML XMLNS:IE>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<IE:Download ID="include" STYLE="behavior:url(#default#download)" />

贴两个关于treeview的
<script language="javascript">
<!--
//初始化选中节点
function initchecknode()
{
var node=TreeView1.getTreeNode("1");
node.setAttribute("Checked","true");
setcheck(node,"true");
FindCheckedFromNode(TreeView1);
}
//oncheck事件
function tree_oncheck(tree)
{
var node=tree.getTreeNode(tree.clickedNodeIndex);
var Pchecked=tree.getTreeNode(tree.clickedNodeIndex).getAttribute("checked");
setcheck(node,Pchecked);
document.all.checked.value="";
document.all.unchecked.value="";
FindCheckedFromNode(TreeView1);
}
//设置子节点选中
function setcheck(node,Pc)
{
var i;
var ChildNode=new Array();
ChildNode=node.getChildren();
if(parseInt(ChildNode.length)==0)
return;
else
{
for(i=0;i<ChildNode.length;i++)
{
var cNode;
cNode=ChildNode[i];
if(parseInt(cNode.getChildren().length)!=0)

}
//获取所有节点状态
function FindCheckedFromNode(node) {

var cNode;

if (cNode.getAttribute("Checked"))
AddChecked(cNode);
else
AddUnChecked(cNode);
if (parseInt(cNode.getChildren().length) != 0 ) {
FindCheckedFromNode(cNode);
}
}
}
//添加选中节点
function AddChecked(node) {

document.all.checked.value += ',';
}
//添加未选中节点
function AddUnChecked(node) {

document.all.unchecked.value += ',';
}

treeview中如何在服务器端得到客户端设置后的节点选中状态
<script language="C#" runat="server">
private void Button1_Click(object sender, System.EventArgs e)
{
Response.Write(TreeView1.Nodes[0].Checked);
}
</script>
<script language="javascript">
function set_check()
{
var nodeindex = "0";
var node=TreeView1.getTreeNode(nodeindex);
node.setAttribute("Checked","True");
TreeView1.queueEvent('oncheck', nodeindex);
}
</script>
三個實用的小技巧:關閉輸入法.禁止貼上.禁止複製
關閉輸入法
本文字框輸入法被關閉：
語法： style="ime-mode:disabled"
範例： <input type="text" name="textfield" style="ime-mode:disabled">
禁止貼上
本文字框禁止貼上文字：
語法：onpaste="return false"
範例：<input type="text" name="textfield" onpaste="return false">
禁止複製
本文字框禁止複製：
語法：oncopy="return false;" oncut="return false;"
範例：<input name="textfield" type="text" value="不能複製裡面的字" oncopy="return false;" oncut="return false;">
