Web page javascript essence code set_basic knowledge

[1. Ordinary pop-up window]


works on some older browsers. In these old browsers, the code in the tag will not be displayed as text

Come out. You can use either single quotes or double quotes, just don't mix them.

【2. Pop-up window after setting】



Parameter explanation:


End of js script
【 3. Use functions to control pop-up windows]
The following is a complete code.

.....




A function openwin() is defined here, how to call it?
Method 1:
A window pops up when the browser reads the page;
Method 2:
A window pops up when the browser leaves the page;
Method 3: Call with a link: Method 4: Call with button:


[4. Pop up 2 windows at the same time]
Slightly change the source code:




To avoid pop-up The two windows are covered. Use top and left to control the pop-up position so that they do not cover each other. Finally, use the four methods mentioned above

to call it. Note: The names of the two windows (newwindows and newwindow2) should not be the same, or they should all be empty.

[5. The main window opens the file 1.htm, and the small window page.html pops up at the same time]
The following code is added to the main window
area:

Join the
area:

open
.

　[6. Timing closing control of pop-up windows]
Now let’s control the pop-up windows, and the effect will be better. If we add a small piece of code to the pop-up page (
note that it is added to the HTML of page.html, not the main page, otherwise...), let it close automatically after 10 seconds, right? Cooler?
First, add the following code to the
area of ​​the page.html file:


Then, use the sentence

to replace the original This sentence will do. (Don’t forget to write this
sentence! The function of this sentence is to call the code to close the window, and then close the window automatically after 10 seconds.)

　[7. In the pop-up Add a close button to the window]





[8. Pop-up window included - two windows on one page]
Through the following example, you can complete the above effect in one page.





>

Look at the code in OpenWindow.document.write(). Isn’t it standard HTML? Just write more lines according to the format

. Be sure to note that an error will occur if there is one more label or one less label. Remember to end it with OpenWindow.document.close().


[9. Cookie Control of Pop-up Window]

Recall that although the above pop-up window is cool, it has a little problem. For example, if you put the above script in a page that needs to be visited frequently (such as the homepage), then every time you refresh the page, the window will pop up. Isn't it very annoying? :-(
Solution:
We can use cookies to control it. First, add the following code to the
area of ​​the main page HTML:



Then, replace the original sentence

in the main page with (note it is not openwin but loadpop!). You can try refreshing the page or re-entering it. Pages and windows will never pop up again. The real

Pop-Only-Once!

At this point, the production and application skills of pop-up windows are basically completed.


　　1.弹启一个全屏窗口 

 
; 
[url]www.e3i5.com[/url] 
 
 

　　2.弹启一个被F11化后的窗口 

 
; 
[url]www.e3i5.com[/url] 
 
 

　　3.弹启一个带有收藏链接工具栏的窗口 

 

('http://www.pconline.com.cn','example03','width=400,height=300,directories');> 
[url]www.e3i5.com[/url] 
 
 

　　4.网页对话框 

 
<script> <BR><!-- <BR>showModalDialog <br><br>('http://www.pconline.com.cn','example04','dialogWidth:400px;dialogHeight:300px; <BR>dialogLeft:200px;dialogTop:150px;center:yes;help:yes;resizable:yes;status:yes') <BR>//--> <BR></script> 
[url]www.e3i5.com[/url] 
 
 

 
<script> <BR><!-- <BR>showModelessDialog <br><br>('http://www.pconline.com.cn','example05','dialogWidth:400px;dialogHeight:300px; <BR>dialogLeft:200px;dialogTop:150px;center:yes;help:yes;resizable:yes;status:yes') <BR>//--> <BR></script> 
 target=_blank>[url]http://www.pconline.com.cn[/url] 
 
 

　　showModalDialog()与showModelessDialog()的区别，在于showModalDialog()打开模式窗口，

showModelessDialog()打开无模式窗口。 

dialogHeight: iHeight 设置对话框窗口的高度。 
dialogWidth: iWidth 设置对话框窗口的宽度。 　　 
dialogLeft: iXPos 设置对话框窗口相对于桌面左上角的left位置。 
dialogTop: iYPos 设置对话框窗口相对于桌面左上角的top位置。 
center: {yes no 1 0 } 指定是否将对话框在桌面上居中，默认值是“yes”。 
help: {yes no 1 0 } 指定对话框窗口中是否显示上下文敏感的帮助图标。默认值是“yes”。 　　 
resizable: {yes no 1 0 } 指定是否对话框窗口大小可变。默认值是“no”。 
status: {yes no 1 0 } 指定对话框窗口是否显示状态栏。对于非模式对话框窗口，默认值是“yes”；

对于模式对话框窗口，默认值是 “no”。 


网页经典代码 
1. 将彻底屏蔽鼠标右键,无右键菜单 
 

也可以用于网页中Table框架中 

no

 


2.取消选取、防止复制 
 


3.不准粘贴 
 


4.防止复制 
 


5.IE地址栏前换成自己的图标 
 

说明：关于favicon.ico文件的制作。你可以先在FW中做一个图片，属于你自己站点一个小图标。然后在

ACD see将文件属性改为*.ico，然后将你做的*.ICO文件传到你的服务器目录中，然后就可以使用以上代

码来实现，当别人登陆你的站点时，地址栏里使用的就是你自定义的图标了。 


6.可以在收藏夹中显示出你的图标 
 

说明：制作方法和上面的一样。只是显示的方式不同，这个是在别人收藏你的网页地址时显示的个性图

标。 


7.关闭输入法 
 

说明：这段代码是在表格提交时用到的。也就是在输入数据时不可以使用其他输入法模式。 


8.永远都会带着框架 
<script><!-- <BR>　if (window == top)top.location.href = frames.htm;// --></script> 

说明：frames.htm为你的网页，这也是保护页面的一种方法 


9.防止被人frame 
<script><!-- <BR>　if (top.location != self.location)top.location=self.location; <BR>// --></script> 


10.网页将不能被另存为 
 
说明：的用法很广，其中一条就是可以使JS广告失效。 


11.查源文件 
onclick=window.location = 'view-source:'+ target=_blank>[url]http://bbs.055.cn/test.htm

[/url]';> 


12.COOKIE脚本记录，有很大的用处哦 

function get_cookie(Name) { 
var search = Name + = 

var returnvalue = ; 

if (documents.cookie.length > 0) { 

offset = documents.cookie.indexOf(search) 

if (offset != -1) { // if cookie exists 

offset += search.length 

// set index of beginning of value 

end = documents.cookie.indexOf(;, offset); 

// set index of end of cookie value 

if (end == -1) 

end = documents.cookie.length; 

returnvalue=unescape(documents.cookie.substring(offset, end)) 

} 

} 

return returnvalue; 

} 


function loadpopup(){ 

if (get_cookie('popped')==''){ 

openpopup() 

documents.cookie=popped=yes 

} 

} 

说明：以上是JS代码，请自己加起始符和结束符 


13.内框架 
src：文件的路径，既可是HTML文件，也可以是文本、ASP等　　 
width、height：内部框架区域的宽与高； 　　 
scrolling:当SRC的指定的HTML文件在指定的区域不显不完时，滚动选项，如果设置为NO，则不出现滚动

条；如为Auto：则自动出现滚动条；如为Yes，则显示; 　FrameBorder：区域边框的宽度，为了让“内

部框架“与邻近的内容相融合，常设置为0。 
name:框架的名字，用来进行识别。 
比如: 　当你想用父框架控制内部框架时，可以使用： target=框架的名字来控制。 

例子： 

14.自动跳转
在源代码中的…加入如下代码：


说明：content=3 表示3秒刷新到URL


15.如何改变链接的鼠标形状
只需在链接上加上这一代码就行的了
或者跟上面的用CSS写也行

style=cursor:hand　　　　　 　style=cursor:crosshair
style=cursor:text 　　　　　　style=cursor:wait
style=cursor:move 　　　　　　style=cursor:help
style=cursor:e-resize 　　　　
style=cursor:n-resize
style=cursor:nw-resize 　 　　style=cursor:w-resize
style=cursor:s-resize 　　　　
style=cursor:se-resize
style=cursor:sw-resize

以上代码你只需要加到连接或是页面的style区里就可以实现鼠标多样化。


16.全屏显示

'big', 'fullscreen=yes')>

把它放到中。


17.设为首页

<script> <BR><!-- <BR>function defaul_home(){ <BR>this.home.style.behavior='url(#default#homepage)';this.home.setHomePage([url] <br><br>http://bbs.055.cn/[/url]'; <BR>} <BR>var focusok=false; <BR>if (navigator.appName == Netscape{ <BR>focusok=true; <BR>} <BR>vers=navigator.appVersion; <BR>if (navigator.appName == Microsoft Internet Explorer{ <BR>pos=vers.lastIndexOf('.'); <BR>vers=vers.substring(pos-1,vers.length); <BR>} <BR>proper_version=parseFloat(vers); <br><br>if(proper_version>=5){ <BR>focusok=true; <BR>} <BR>function launchstock1(htmlurl){ <BR>var stock=window.open <br><br>(htmlurl,stock,top=2,left=2,toolbar=no,location=no,directories=no,status=no,menubar=no,scro <br><br>llbars=yes, <BR>resizable=no,width=700,height=510; <BR>if(focusok){ <BR>stock.focus(); <BR>} <BR>return true; <BR>} <BR>function launchstock(){ <BR>var stock=window.open <br><br>(,stock,top=2,left=2,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars= <br><br>yes, <br><br>resizable=no,width=700,height=510; <BR>if(focusok){ <BR>stock.focus(); <BR>} <BR>return true; <BR>} <BR>// --> <BR></script>
设为首页


18.这里是加入收藏夹的代码


target=_self title=拂晓雅阁>加入收藏夹


19.flash图片效果
以下代码加入区域
<script> <BR><!-- <BR>function makevisible(cur,which){ <BR>if (which==0) <BR>cur.filters.alpha.opacity=100 <BR>else <BR>cur.filters.alpha.opacity=20 <BR>} <br><br>//--> <br><br></script>
以下代码加入区域

(this,0) onMouseOut=makevisible(this,1) width=63 height=56> //图片地址请自己改


20.load 进度条

id=Q>

<script> <BR>var R = 0; load(); <BR>function load() {R = R + 2; Q.style.width = R + %; time= setTimeout(load(),50); <BR>if (R > 100) {clearTimeout(time); P.style.width=0}} <BR></script>
27 全屏
<script> <BR>window.open('index.asp','','fullscreen=1'); <BR></script>


21.背景图片滚动


bgcolor=#000080 topmargin=8>
<script> <BR>var backgroundOffset = 0; <BR>var bgObject = eval('document.body'); <BR>function scrollBG(maxSize) {backgroundOffset = backgroundOffset + 1; <BR>if (backgroundOffset > maxSize) backgroundOffset = 0; <BR>bgObject.style.backgroundPosition = 0 + backgroundOffset;} <BR>var ScrollTimer = window.setInterval(scrollBG(410), 20) <BR></script>


22.网页不会被缓存

HTMl网页



或者
ASP网页
　Response.Expires = -1
　Response.ExpiresAbsolute = Now() - 1
　Response.cachecontrol = no-cache
PHP网页
header(Expires: Mon, 26 Jul 1997 05:00:00 GMT;
header(Cache-Control: no-cache, must-revalidate;
header(Pragma: no-cache;

23.最小化、最大化、关闭窗口







24.判断上一页的来源

asp页:
request.servervariables(HTTP_REFERER
java script:
document.referrer


25.光标是停在文本框文字的最后

<script> <BR>function cc() <BR>{ <BR>　var e = event.srcElement; <BR>　var r =e.createTextRange(); <BR>　r.moveStart('character',e.value.length); <BR>　r.collapse(true); <BR>　r.select(); <BR>} <BR></script>



JavaScript几个表单常用的验证脚本：

     只能输入数字

       onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/

[^\d]/g,''))">

 
     ENTER键可以让光标移到下一个输入框

 


     只能是中文


event.keyCode=9"> 


     屏蔽输入法

 


     只能输入英文和数字

       onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/

[^\d]/g,''))"
       onkeydown="if(event.keyCode==13)event.keyCode=9"> 



     只能显示，不能修改



     禁止复制选择等................

<script> <br><br> 双击鼠标滚动屏幕的代码 <BR>var currentpos,timer; <BR>function initialize() <BR>{ <BR>timer=setInterval ("scrollwindow ()",30); <BR>} <BR>function sc() <BR>{ <BR>clearInterval(timer); <BR>} <BR>function scrollwindow() <BR>{ <BR>currentpos=document.body.scrollTop; <BR>window.scroll(0,++currentpos); <BR>if (currentpos !=document.body.scrollTop) <BR>sc(); <BR>} <BR>document.onmousedown=sc <BR>document.ondblclick=initialize <BR> </script>
