1：获得IE版本
<script type="text/javascript">
var ua=navigator.userAgent.toLowerCase();
var IEVer= /msie/.test(ua)?parseFloat(ua.match(/msie ([\d.]+)/)[1]):false;
if(IEVer==6)
{
}
</script>
2：GridView1设置主键
GridView1.DataKeyNames = new string[] { "id"};//设置主键（这一句最好放在GridView1.DataBind();上面）
string id = GridView1.DataKeys[e.RowIndex].Value.ToString();
3：<a href="javascript:scroll(0,0)">返回顶部</a>
4：[javascript]删除div的方法
方法一:div.removeNode(true);//火狐不支持
方法二:div.parentNode.removeChild(div);//IE火狐都支持
5：vs 快捷键
1：Ctrl+Shift+L: 删除当前行
2：Ctrl+E,W: 自动换行
3：Ctrl+G: 转到指定行
6： this.lbtnDelALL.Attributes.Add("onclick", "return confirm('确定要删除吗?')");
7：框架高度自适应<iframe id="iFrame1" name="iFrame1" width="100%" onload="this.height=iFrame1.document.body.scrollHeight" frameborder="0" src="index.htm"></iframe>
8：$("button:eq(1)").click(function () {
$("#panel").stop();//停止当前动画，继续下一个动画
});
$("button:eq(2)").click(function () {
$("#panel").stop(true);//清除元素的所有动画
});
$("button:eq(3)").click(function () {
$("#panel").stop(false,true);//让当前动画直接到达末状态 ，继续下一个动画
});
$("button:eq(4)").click(function () {
$("#panel").stop(true,true);//清除元素的所有动画，让当前动画直接到达末状态
});
9：中文cookie
设置 Response.Cookies["admin"]["flag"] = HttpUtility.UrlEncode(dt.Rows[0]["loginlimit"].ToString());
读取 Encoding stre = Encoding.GetEncoding("UTF-8");
string limit = HttpUtility.UrlDecode(Request.Cookies["user"]["flag"].ToString());
10：打开新窗口 DropDownList1.Attributes.Add("onchange", "javascript:window.open(this.options[this.selectedIndex].value)");
11：3：this.ddlPage.Items.Add(new ListItem("=请选择=", "0"));
this.ddlPage.Items.Add(new ListItem("第" + i.ToString() + "页", i.ToString()));
12：1：Response.AddHeader("Refresh", "10"); 写在pageload中
<meta http-equiv="Refresh" content="10" /> 写在<head></head>中
<%Response.AddHeader("Refresh", "10"); %> 写在body中
13：隔行变色 $(".color").find("tr").each(function(i){this.style.backgroundColor=['#ffffff','#eee'][i%2]})
14：弹出窗口：
<script type="text/javascript" language="javascript">
function sAlert(){
var fa=document.getElementById("fa");
fa.innerHTML="法律声明";
var msgw,msgh,bordercolor;
msgw=788;//提示窗口的宽度
msgh=328;//提示窗口的高度
titleheight=15 //提示窗口标题高度
bordercolor="#ffffff";//提示窗口的边框颜色
titlecolor="#ffffff";//提示窗口的标题颜色
var sWidth,sHeight;
sWidth=document.body.offsetWidth;
sHeight=document.body.scrollHeight+30;//screen.height;
var bgObj=document.createElement("div");
bgObj.setAttribute('id','bgDiv');
bgObj.style.position="absolute";
bgObj.style.top="0";
bgObj.style.background="#777";
bgObj.style.filter="progid:DXImageTransform.Microsoft.Alpha(opacity=40)";
bgObj.style.left="0";
bgObj.style.width=sWidth + "px";
bgObj.style.height=sHeight + "px";
bgObj.style.zIndex = "10000";
document.body.appendChild(bgObj);
var msgObj=document.createElement("div")
msgObj.setAttribute("id","msgDiv");
msgObj.setAttribute("align","center");
msgObj.style.background="white";
msgObj.style.border="1px solid " + bordercolor;
msgObj.style.position = "absolute";
msgObj.style.left = "36%";
msgObj.style.top = "30%";
msgObj.style.font="12px/1.6em Verdana, Geneva, Arial, Helvetica, sans-serif";
msgObj.style.marginLeft = "-225px" ;

var fa=document.getElementById("fa");
fa.innerHTML="<a onclick=\"sAlert();\">法律声明</a>";
document.getElementById("msgDiv").removeChild(title);
document.body.removeChild(msgObj);
}
document.body.appendChild(msgObj);
document.getElementById("msgDiv").appendChild(title);
var txt=document.createElement("p");
txt.style.margin="0"
txt.setAttribute("id","msgTxt");
txt.innerHTML="<img src=\"images/fl.jpg\">";
document.getElementById("msgDiv").appendChild(txt);
}
</script>
15：删除数据库中重复记录：
delete from DotBBS_t130dft_User
where userid in (select userid from DotBBS_t130dft_User group by userid having count(userid) > 1)
and uid not in (select min(uid) from DotBBS_t130dft_User group by userid having count(userid )>1)
16：标题跑马灯
<script type="text/javascript">
function set() {
var tit = document.title;
var a = tit.substring(0, 1);
var b = tit.substring(1, tit.length);
document.title = b + a;
}
setInterval(set,500);
</script>
17：删除文本编辑器上传的图片
private string GetImgString(string str)
{
string res = "";
string tem = "";
int startIndex = 0;
int endIndex = 0;
for (int i = 0; i < str.Length - 3; i++)
{
tem = str.Substring(i, 3).ToLower();
if (tem == "src")
{
startIndex = i;
str = str.Substring(startIndex+5);
endIndex = str.IndexOf('>');
res = str.Substring(0, endIndex-3);
str = str.Substring(endIndex);
res += "|"+GetImgString(str); //递归调用
break;
}
}
return res;
}
protected void dgrdName_ItemCommand(object source, DataGridCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
int id = Convert.ToInt32(e.CommandArgument.ToString());
string str = "select [content] from news where id="+id+"";
string content = haian.ReadOut2(str);
string img=GetImgString(content);
img = img.Substring(0,img.Length-1);
string [] arr=img.Split('|');
for (int i = 0; i < arr.Length;i++ )
{
File.Delete(HttpContext.Current.Server.MapPath("/" + arr[i]));
}
string delstr = "delete from news where id=" + id + "";
haian.myCommand(delstr);
DataBind();
}
}
17：取出文本编辑器里上传的所有图片
private string GetImgString(string str)
{
string res = "";
string tem = "";
int startIndex = 0;
int endIndex = 0;
for (int i = 0; i < str.Length; i++)
{
tem = str.Substring(i, 4).ToLower();
if (tem == "<img")
{
startIndex = i;
str = str.Substring(startIndex);
endIndex = str.IndexOf('>');
res = str.Substring(0, endIndex + 1);
break;
}
}
return res;
}
18：去掉IE浏览器里的脚本控件提示
<!-- saved from url=(0014)about:internet -->
19：去除超链接边框
a{blr:expression(this.onFocus=this.blur())}
20：去除IE下flash边框
<script src="javascript:'document.body.innerHTML+=\'\'';"></script>
21：判断浏览器类型
<script type="text/javascript">
var Sys = {};
var ua = navigator.userAgent.toLowerCase();
var s;
(s = ua.match(/msie ([\d.]+)/)) ? Sys.ie = s[1] :
(s = ua.match(/firefox\/([\d.]+)/)) ? Sys.firefox = s[1] :
(s = ua.match(/chrome\/([\d.]+)/)) ? Sys.chrome = s[1] :
(s = ua.match(/opera.([\d.]+)/)) ? Sys.opera = s[1] :
(s = ua.match(/version\/([\d.]+).*safari/)) ? Sys.safari = s[1] : 0;
//以下进行测试
var colin=document.getElementById("colin");
if(Sys.ie=="8.0")
{
colin.style.marginTop="0px";
}
if (Sys.ie) document.write('IE: ' + Sys.ie);
if (Sys.firefox) document.write('Firefox: ' + Sys.firefox);
if (Sys.chrome) document.write('Chrome: ' + Sys.chrome);
if (Sys.opera) document.write('Opera: ' + Sys.opera);
if (Sys.safari) document.write('Safari: ' + Sys.safari);
</script>
22：防下载
<div style="display:none;">
<script language="javascript">
window.setInterval("clipboardData.setData('text','')",100);
</script>
<noscript><iframe src=*.html></iframe></noscript>
</div>
23：初始化滚动条
<script>
function scrollWindow()
{
window.scrollTo(0,150)
}
scrollWindow();
</script>
<body bgcolor="#000000" style="margin:0;" onload="scrollWindow();" scroll="no">
flash 部分
1：鼠标悬停加颜色
var s:ColorTransform = new ColorTransform();
s.color = 0x000000;
e.currentTarget.transform.colorTransform = s;
2：鼠标悬停设置透明度
e.target.alpha=0.8;
3：页面跳转
navigateToURL(new URLRequest("news.aspx"),"_self");
中文转码跳转
navigateToURL(new URLRequest("floor.aspx?city="+encodeURI(arr[i])),"_self");
4：动态读取xml文件
var newsXml:XML=new XML();
var xmlLoader:URLLoader=new URLLoader();
xmlLoader.load(new URLRequest("Common/news.ashx"));
xmlLoader.addEventListener(Event.COMPLETE,loadNewsXml);
function loadNewsXml(evt:Event){
newsXml=XML(evt.target.data);
//trace(newsXml.news)
viewNewsList(newsXml.news);
}
