当前位置 : 网站开发制作30个技巧
1、οncοntextmenu= "window.event.returnValue=false " 将彻底屏蔽鼠标右键
<table border οncοntextmenu=return(false)> <td> no </table> 可用于Table
2、<body onselectstart= "return false "> 取消选取、防止复制
3、οnpaste= "return false " 不准粘贴
4、οncοpy= "return false; " oncut= "return false; " 防止复制
5、<link rel= "Shortcut Icon " href= "favicon.ico "> IE地址栏前换成自己的图标
6、<link rel= "Bookmark " href= "favicon.ico "> 可以在收藏夹中显示出你的图标
7、<input style= "ime-mode:disabled "> 关闭输入法
8、永远都会带着框架
<script language= "JavaScript"> <!--
if (window == top)top.location.href = "frames.htm "; //frames.htm为框架网页
// --> </script>
9、防止被人frame
<script language=“JavaScript”> <!--
if (top.location != self.location)top.location=self.location;
// --> </script>
10、网页将不能被另存为
<noscript> <iframe src= "/blog/*.html> "; </iframe> </noscript>
11、<input type=button value=查看网页源代码
οnclick= "window.location = "view-source: "+ "http://www.163.com " ">
12、删除时确认
<a href= "javascript:if(confirm( "确实要删除吗? "))location= "boos.asp?&areyou=删除&page=1 " "> 删除 </a>
13、取得控件的绝对位置
//Javascript
<script language= "Javascript ">
function getIE(e){
var t=e.offsetTop;
var l=e.offsetLeft;
while(e=e.offsetParent)
alert( "top= "+t+ "/nleft= "+l);
}
</script>
//VBScript
<script language= "VBScript "> <!--
function getIE()
dim t,l,a,b
set a=document.all.img1
t=document.all.img1.offsetTop
l=document.all.img1.offsetLeft
while a.tagName <> "BODY "
set a = a.offsetParent
t=t+a.offsetTop
l=l+a.offsetLeft
wend
msgbox "top= "&t&chr(13)& "left= "&l,64, "得到控件的位置 "
end function
--> </script>
14、光标是停在文本框文字的最后
<script language= "javascript ">
function cc(){
var e = event.srcElement;
var r =e.createTextRange();
r.moveStart( "character ",e.value.length);
r.collapse(true);
r.select();
}
</script>
<input type=text name=text1 value= "123 " οnfοcus= "cc() ">
15、判断上一页的来源
javascript:
document.referrer
16、最小化、最大化、关闭窗口
<object id=hh1 classid= "clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11 ">
<param name= "Command " value= "Minimize "> </object>
<object id=hh2 classid= "clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11 ">
<param name= "Command " value= "Maximize "> </object>
<OBJECT id=hh3 classid= "clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11 ">
<PARAM NAME= "Command " VALUE= "Close "> </OBJECT>
<input type=button value=最小化 οnclick=hh1.Click()>
<input type=button value=最大化 οnclick=hh2.Click()>
<input type=button value=关闭 οnclick=hh3.Click()>
17、屏蔽功能键Shift,Alt,Ctrl
<script>
function look(){
if(event.shiftKey)
alert( "禁止按Shift键! "); //可以换成ALT CTRL
}
document.οnkeydοwn=look;
</script>
18、网页不会被缓存
<META HTTP-EQUIV= "pragma " CONTENT= "no-cache ">
<META HTTP-EQUIV= "Cache-Control " CONTENT= "no-cache, must-revalidate ">
<META HTTP-EQUIV= "expires " CONTENT= "Wed, 26 Feb 1997 08:21:57 GMT ">
或者 <META HTTP-EQUIV= "expires " CONTENT= "0 ">
19、怎样让表单没有凹凸感？
<input type=text style= "border:1 solid #000000 "/>
或
<input type=text style= "border-left:none; border-right:none; border-top:none; border-bottom:
1 solid #000000 "/>
20、<div> <span> & <layer> 的区别？
<div> (division)用来定义大段的页面元素，会产生转行
<span> 用来定义同一行内的元素，跟 <div> 的唯一区别是不产生转行
<layer> 是ns的标记，ie不支持，相当于 <div>
21、让弹出窗口总是在最上面:
<body οnblur= "this.focus(); ">
22、不要滚动条?
让竖条没有: <body style= "overflow:scroll;overflow-y:hidden "></body>
让横条没有: <body style= "overflow:scroll;overflow-x:hidden "></body>
两个都去掉？更简单了<body scroll= "no "></body>
23、怎样去掉图片链接点击后，图片周围的虚线？
<a href= "# " onFocus= "this.blur() "> <img src= "/blog/logo.jpg " border=0/> </a>
24、电子邮件处理提交表单
<form name= "form1 " method= "post " action= "mailto:**** @ ***.com " enctype= "text/plain ">
<input type=submit>
</form>
25、在打开的子窗口刷新父窗口的代码里如何写？ window.opener.location.reload()
26、如何设定打开页面的大小 <body οnlοad= "top.resizeTo(300,200); ">
打开页面的位置 <body οnlοad= "top.moveBy(300,200); ">
27、在页面中如何加入不是满铺的背景图片,拉动页面时背景图不动
<style>
body{
background-image:url(/blog/logo.gif); background-repeat:no-repeat;
background-position:center;background-attachment: fixed
}
</style>
28、 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>
29、获得一个窗口的大小 document.body.clientWidth; document.body.clientHeight
30、怎么判断是否是字符
if (/[^/x00-/xff]/g.test(s)) alert( "含有汉字 ");
