40种网站设计常用技巧

1 . oncontextmenu = " window.event.returnValue=false "  将彻底屏蔽鼠标右键
< table border oncontextmenu = return ( false ) >< td > no </ table >  可用于Table

2 < body onselectstart = " return false " >  取消选取、防止复制

3 . onpaste = " return false "  不准粘贴

4 . oncopy = " 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 
onclick
= " window.location =  " view - source: " " http: // www.williamlong.info"">

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 "  onfocus = " 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 onclick = hh1.Click() >
< input type = button value = 最大化 onclick = hh2.Click() >
< input type = button value = 关闭 onclick = hh3.Click() >
本例适用于IE

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.onkeydown
= 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 " >  

< input type = text style = " border-left:none; border-right:none; border-top:none; border-bottom: 

1 solid #000000
" ></ textarea >

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 onblur = " 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 onload = " top.resizeTo(300,200); " >
打开页面的位置
< body onload = " 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 " );
else  alert( " 全是字符 " );

31 .TEXTAREA自适应文字行数的多少
< textarea rows = 1  name = s1 cols = 27  onpropertychange = " this.style.posHeight=this.scrollHeight " >
</ textarea >

32 . 日期减去天数等于第二个日期
< script language = Javascript >
function  cc(dd,dadd)
{
// 可以加上错误处理
var  a  =   new  Date(dd)
=  a.valueOf()
=  a  -  dadd  *   24   *   60   *   60   *   1000
=   new  Date(a)
alert(a.getFullYear() 
+   " "   +  (a.getMonth()  +   1 +   " "   +  a.getDate()  +   " " )
}
cc(
" 12/23/2002 " , 2 )
</ script >

33 . 选择了哪一个Radio
< HTML >< script language = " vbscript " >
function  checkme()
for  each ob  in  radio1
if  ob.checked then window.alert ob.value
next
end 
function
</ script >< BODY >
< INPUT name = " radio1 "  type = " radio "  value = " style "  checked > Style
< INPUT name = " radio1 "  type = " radio "  value = " barcode " > Barcode
< INPUT type = " button "  value = " check "  onclick = " checkme() " >
</ BODY ></ HTML >

34 .脚本永不出错
< SCRIPT LANGUAGE = " JavaScript " >  
<!--  Hide 
function  killErrors() { 
return   true

window.onerror 
=  killErrors; 
//  --> 
</ SCRIPT >

35 .ENTER键可以让光标移到下一个输入框
< input onkeydown = " if(event.keyCode==13)event.keyCode=9 " >

36 . 检测某个网站的链接速度:
把如下代码加入
< body > 区域中:
< script language = Javascript >
tim
= 1
setInterval(
" tim++ " , 100 )
b
= 1
var  autourl = new  Array()
autourl[
1 ] = " www.njcatv.net "
autourl[
2 ] = " javacool.3322.net "
autourl[
3 ] = " www.sina.com.cn "
autourl[
4 ] = " www.nuaa.edu.cn "
autourl[
5 ] = " www.cctv.com "
function  butt(){
document.write(
" <form name=autof> " )
for ( var  i = 1 ;i < autourl.length;i ++ )
document.write(
" <input type=text name=txt " + i + "  size=10 value= " / blog / 测试中 > "  =》<input type=text 
name=url
" + i + "  size=40> =》<input type=button value=GO 

onclick=window.open(this.form.url
" + i + " .value)><br/> " )
document.write(
" <input type=submit value=刷新></form> " )
}
butt()
function  auto(url)
else

b
++
}
function  run(){ for ( var  i = 1 ;i < autourl.length;i ++ )document.write( " <img src=http:// " + autourl + " / " + Math.random() + "  width=1 height=1 

onerror=auto(
" http: // "+autourl+"")>")}
run() </ script >

37 . 各种样式的光标
auto :标准光标
default  :标准箭头
hand :手形光标
wait :等待光标
text :I形光标
vertical
- text :水平I形光标
no

38 .页面进入和退出的特效
进入页面
< meta http - equiv = " Page-Enter "  content = " revealTrans(duration=x, transition=y) " >
推出页面
< meta http - equiv = " Page-Exit "  content = " revealTrans(duration=x, transition=y) " >  
这个是页面被载入和调出时的一些特效。duration表示特效的持续时间,以秒为单位。transition表示使用哪种特效,取值为1
- 23 :
  
0  矩形缩小 
  
1  矩形扩大 
  
2  圆形缩小
  
3  圆形扩大 
  
4  下到上刷新 
  
5  上到下刷新
  
6  左到右刷新 
  
7  右到左刷新 
  
8  竖百叶窗
  
9  横百叶窗 
  
10  错位横百叶窗 
  
11  错位竖百叶窗
  
12  点扩散 
  
13  左右到中间刷新 
  
14  中间到左右刷新
  
15  中间到上下
  
16  上下到中间 
  
17  右下到左上
  
18  右上到左下 
  
19  左上到右下 
  
20  左下到右上
  
21  横条 
  
22  竖条 
  
23  以上22种随机选择一种

39 .在规定时间内跳转
< META http - equiv = V = " REFRESH "  content = " 5;URL=http://www.williamlong.info " >  

40 .网页是否被检索
< meta name = " ROBOTS "  content = " 属性值 " >
  其中属性值有以下一些:
  属性值为
" all " : 文件将被检索,且页上链接可被查询;
  属性值为
" none " : 文件不被检索,而且不查询页上的链接;
  属性值为
" index " : 文件将被检索;
  属性值为
" follow " : 查询页上的链接;
  属性值为
" noindex " : 文件不检索,但可被查询链接;
  属性值为
" nofollow " : 文件不被检索,但可查询页上的链接。

最大化窗口?
< script language = " JavaScript " >
<!--
self.moveTo(
0 , 0 )
self.resizeTo(screen.availWidth,screen.availHeight)
// -->
</ script >




解决问题:由于层与下拉框之间的优先级是:下拉框 
>  层,因此在显示的时候,会因为优先级的次序而会出现如上问题。(如果几个元素都是层的话,我们可以通过层的 z - index 属性来设置)解决办法就是:给层中放一个优先级比下拉框更高的元素(iframe),从而解决此问题!具体解决代码如下:

< div id = " menu "  style = " position:absolute; visibility:hidden; top:20px; left:20px; width:100px; height:200px; background-color:#6699cc; " >
< table >
< tr >< td > item  1 </ td ></ tr >
< tr >< td > item  2 </ td ></ tr >
< tr >< td > item  3 </ td ></ tr >
< tr >< td > item  4 </ td ></ tr >
< tr >< td > item  5 </ td ></ tr >
</ table >
< iframe src = " /blog/javascript:false "  style = " position:absolute; visibility:inherit; top:0px; left:0px; width:100px; height:200px; z-index:-1; filter='progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0)'; " ></ iframe >
</ div >

< a href = " # "  onclick = " document.getElementById('menu').style.visibility='visible' " > menu </ a >

< form >
< select >< option > A form selection list </ option ></ select >
</ form >

输入框也可以做的很漂亮了
< div align = " center " >< input type = " hidden "  name = " hao "  value = " yes " >
外向数:
< input 
name
= answer 
style
= " color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) " >
 没回答的题数:
< input 
name
= unanswer id = " unanswer "  
style
= " color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) " >
< br />
总得分:
< input 
name
= score id = " score "  
style
= " color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) " >
 结    论:
< input 
name
= xgjg id = " xgjg "  
style
= " color: rgb(255,0,0); border-left: medium none; border-right: medium none; border-top: medium none; border-bottom: 1px solid rgb(192,192,192) " >
< br />
< br />  

< input onClick = processForm( this .form) style = " FONT-FAMILY: 宋体; FONT-SIZE: 9pt "  type = button value = 查看结果 name = " button " >  
< input type = " reset "  name = " Submit "  value = " 重做 " >
</ div >
注意:修改
< body > < body onload = " max.Click() " > 即为打开最大

化窗口,而如果改为
< body onload = " min.Click() " > 就变为窗口一打开就最小化

< object id = " min "  type = " application/x-oleobject "  classid = " clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11 " >
< param name = " Command "  value = " Minimize " >
</ object >   < object id = " max "  type = " application/x-oleobject "  classid = " clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11 " >
< param name = " Command "  value = " Maximize " >
</ object >
</ body >

页面自动刷新(说明)

当你做网页时,是不是有的时候想让你的网页自动不停刷新,或者过一段时间自动跳转到另外一个你自己设定的页面?其实实现这个效果非常地简单,而且这个效果甚至不能称之为特效。你只要把如下代码加入你的网页中就可以了。

1 ,页面自动刷新:把如下代码加入 < head > 区域中 < meta http - equiv = " refresh "  content = " 20 " > ,其中20指每隔20秒刷新一次页面.

2 ,页面自动跳转:把如下代码加入 < head > 区域中 < meta http - equiv = " refresh "  content = " 20;url=http://www.williamlong.info " > ,其中20指隔20秒后跳转到http: // www.williamlong.info页面。 

页面自动关闭

5000是指时间
< body onLoad = " setTimeout(window.close, 5000) " >  

弹出窗口自动关闭 

10秒后弹出窗口自动关闭

注意:在新的tan.htm的body中要加 
< onLoad = " closeit() " >
head

< script language = " JavaScript " >

<!--

var  gt  =  unescape(' % 3e');

var  popup  =   null ;

var  over  =   " Launch Pop-up Navigator " ;

popup 
=  window.open('', 'popupnav', 'width = 225 ,height = 235 ,resizable = 1 ,scrollbars = auto');

if  (popup  !=   null ) {

if  (popup.opener  ==   null ) {

popup.opener 
=  self; 

}

popup.location.href 
=  'tan.htm';

}

//  -->

</ script >
< body > 注意:这段代码是在新建文件中的
< script language = " JavaScript " >

function  closeit() 

</ script >

这个可不是
< iframe > (引用)呀。是直接调用的。以下代码加入 < body > 区域

< object type = " text/x-scriptlet "  width = " 800 "  height = " 1000 "  data = " ../index.htm " >
</ object >
