JS代碼大全-1

1.  将徹底屏蔽滑鼠右鍵 οncοntextmenu="window.event.returnvalue=false" < table  border oncontextmenu =return(false) >< td > no </ table >   可用于Table

2.  取消選取、防止複制 < body  onselectstart ="return false" >

3.  不準粘貼 οnpaste="return false"

4.  防止複制 οncοpy="return false;" oncut="return false;"

5.  IE位址欄前換成自己的圖示 < link  rel ="Shortcut Icon"  href ="favicon.ico" >

6. 可以在收藏夾中顯示出你的圖示 < link  rel ="Bookmark"  href ="favicon.ico" >  

7.  關閉輸入法 < input  style ="ime-mode:-Disabled" >

8. 永遠都會帶着架構

< script language = " javascript " ><!--

if  (window  ==  top)top.location.href  =   " frames.htm " ;  // frames.htm為架構網頁

//  --></script>

9 . 防止被人frame

< SCRIPT LANGUAGE = javascript ><!--  

if  (top.location  !=  self.location)top.location = self.location;

//  --></SCRIPT>

10 . 網頁将不能被另存為

< noscript >< iframe src =* .html ></ iframe ></ noscript >  

11 . 檢視網頁源代碼 < input  type =button  value =檢視網頁源代碼 

onclick ="window.location = `view-source:`+ http://www.51js.com/`" ; >

12 .删除時确認

< a  href =`javascript:if(confirm("确實要删除嗎?"location="boos.asp?&areyou=删除&page=1"` > 删

除 </ a >  

13 . 取得控件的絕對位置

// javascript

< script language = " javascript " >

function  getIE(E){

var  t = e.offsetTop;

var  l = e.offsetLeft;

while (e = e.offsetParent){

t += e.offsetTop;

l += e.offsetLeft;

}

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後

< 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. 判斷上一頁的來源

javascript:document.referrer

16. 最小化、最大化、關閉視窗

< 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 =關閉  onclick =hh3.Click() >

本例适用于IE
