JS 技巧
1、隐藏状态栏里出现的LINK信息
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/Default2.aspx" Style="z-index: 103;
left: 16px; position: absolute; top: 512px" onMouseOver="window.status='none';return true" onMouseDown="window.status='none';return true">HyperLink</asp:HyperLink>
2、右键屏蔽
<body oncontextmenu=self.event.returnValue=false>
3、调用服务器控件的属性
var radios = document.getElementsByName("RadioButtonList");
for(var i=0;i<radios.length;i++)
{
if(radios[i].checked)
{
alert("当前selectedIndex="+i);
}
}
4、后台调用前台的javascript函数
(1)、前台定义函数
<script type="text/javascript">
function aaa()
{
for(i=0;i<10;i++)
{
alert("当前______FUCK!");
}
}
</script>
(2)、后台引用
Button1.Attributes.Add("OnClick", "aaa()");
5、屏蔽JAVASCRIPT错误
<script language="JavaScript">
<!--
function killErrors(){
return true;
}
window.onerror = killErrors;
-->
</script>
6、检查一段字符串是否全由数字组成
<script language="Javascript"><!--
function checkNum(str){return str.match(//D/)==null}
alert(checkNum("1232142141"))
alert(checkNum("123214214a1"))
// --></script>
7、判断是否是字符
if (/[^/x00-/xff]/g.test(s)) alert("含有汉字");
8、让超链接不显示下划线
<style type="text/css">
<!-
a:link{text-decoration:none}
a:hover{text-decoration:none}
a:visited{text-decoration:none}
->
</style>
9、设置该页为首页
<body bgcolor="#FFFFFF" text="#000000">
<!-- 网址:http://你的网址-->
<a class="chlnk" style="cursor:hand" HREF onClick="this.style.behavior=''url(#default#homepage)''; this.setHomePage(''你的网站名称);"><font color="000000" size="2" face="宋体">设为首页</font></a>
</body>
10、节日倒计时
<Script Language="javascript">
var timedate= new Date("December 25,2003");
var times="圣诞节";
var now = new Date();
var date = timedate.getTime() - now.getTime();
var time = Math.floor(date / (1000 * 60 * 60 * 24));
if (time >= 0)
document.write("现在离"+times+"还有: "+time +"天");
</Script>
11、显示系统当前日期
<script language=javascript>
today=new Date();
function initArray(){
this.length=initArray.arguments.length
for(var i=0;i<this.length;i++)
this[i+1]=initArray.arguments[i] }
var d=new initArray(
" 星期日",
" 星期一",
" 星期二",
" 星期三",
" 星期四",
" 星期五",
" 星期六");
document. write( "<font color=##000000 style=''font-size:9pt;font-family: 宋体''> ", today.getYear(),"年",today.getMonth()+1,"月",today.getDate(),"日",d [today.getDay()+1],"</font>" );
</script>
12、加入收藏
<INPUT name=Button2 onclick="window.external.AddFavorite(location.href, document.title)" type=button value=加入收藏夹>
13、禁止选取<body oncontextmenu="return false" ondragstart="return false" onselectstart ="return false" onselect="document.selection.empty()" oncopy="document.selection.empty()" onbeforecopy="return false"onmouseup="document.selection.empty()>
----
1.让文字不停地滚动
<MARQUEE>滚动文字</MARQUEE>
2.记录并显示网页的最后修改时间
<script language=Javascript>
document.write("最后更新时间: " + document.lastModified + "")
</script>
3.关闭当前窗口
<a href="/"onClick="javascript:window.close();return false;">关闭窗口</a>
4.5秒后关闭当前页
<script language="Javascript">

this.setHomePage('你的网站名称);"><font color="000000" size="2" face="宋体">设为首页</font></a>
</body>
10.节日倒计时
<script Language="Javascript">
var timedate= new Date("December 25,2003");
var times="圣诞节";
var now = new Date();
var date = timedate.getTime() - now.getTime();
var time = Math.floor(date / (1000 * 60 * 60 * 24));
if (time >= 0)
document.write("现在离"+times+"还有: "+time +"天")</script>
11.单击按钮打印出当前页
<script Language="Javascript">
<!-- Begin
if (window.print) {
document.write('<form>'
+ '<input type=button name=print value="打印本页" '
+ 'onClick="javascript:window.print()"></form>');
}
// End -->
</script>
12.单击按钮‘另存为’当前页
<input type="button" name="Button" value="保存本页"
onClick="document.all.button.ExecWB(4,1)">
<object id="button"
width=0
height=0
classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2">

for(var i=0;i<this.length;i++)
this[i+1]=initArray.arguments[i] }
var d=new initArray( " 星期日", " 星期一", " 星期二", " 星期三", " 星期四", " 星期五", " 星期六");
document.write(
"<font color=##000000 style='font-size:9pt;font-family: 宋体'> ",
today.getYear(),"年",today.getMonth()+1,"月",today.getDate(),"日",

function openwindow(thelocation){
temploc=thelocation
if
(!(window.resizeTo&&document.all)&&!(window.resizeTo&&document.getElementById))
{
window.open(thelocation)
return
}
windowsize=window.open("","","scrollbars")
windowsize.moveTo(0,0)
windowsize.resizeTo(100,100)
tenumxt()
}
function tenumxt(){
if (Windowsheight>=screen.availHeight-3)
numx=0
windowsize.resizeBy(5,numx)
Windowsheight+=5
Windowswidth+=5
if (Windowswidth>=screen.width-5)
{
windowsize.location=temploc

17.改变IE地址栏的IE图标
我们要先做一个16*16的icon(图标文件),保存为index.ico。把这个图标文件上传到根目录下并在首页<head></head>之间加上如下代码:
<link REL = "Shortcut Icon" href="index.ico">
******************************************************************************
1.js定时器
<script>
function fun()
{
//your code
}
window.onload=function()
{
window.setInterval("fun()",1000);
}
</script>
<script>
setTimeout("alert('我是setTimeout, 仅出来一次')", 2000);
setInterval("alert('我是Interval, 每5秒一次')",5000);
</script>
2.防止页面被嵌套
<script language="javascript"> <!-- if (top.location != location) top.location.href = location.href; //--> </script> 3.禁止右键JS <script language='javascript'> function click(e) { if (document.all) { if (event.button==1||event.button==2||event.button==3) { oncontextmenu='return false'; } } if (document.layers) { if (e.which == 3) { oncontextmenu='return false'; } } } if (document.layers) { document.captureEvents(Event.MOUSEDOWN); } document.onmousedown=click; document.oncontextmenu = new Function("return false;") var travel=true 2.<BODY oncontextmenu=window.event.returnValue=false |
