JavaScript for IE operation of the classic code of recommendations

I've been working with ajax all this time, so I've had more opportunities to learn about JavaScript. I have collected some code on the Internet about the operation of JavaScript to IE (I can't remember exactly where cope is, so I will not add the source). I feel it is very useful in the development process. Of course, it only applies to IE, FF will have problems. Share now.

1. Will completely block the right mouse button 
oncontextmenu="window.event.returnvalue=false"
 Can be used to Table<table oncontextmenu=return(false)><td>no</table>
2. Unselect and prevent replication 
<bodyonselectstart="returnfalse">
3. Not allowed to paste 
onpaste="returnfalse"
4. To prevent copying 
oncopy="returnfalse;"
oncut="returnfalse;"
5.IE Replace the address bar with your own icon 
<linkrel="ShortcutIcon"href="favicon.ico">
6. Can show your icon in the favorites 
<linkrel="Bookmark"href="favicon.ico">
7. Close the input method 
<inputstyle="ime-mode:disabled">
8. Always carry the frame 
<scriptlanguage="javascript">
<!--
if(window==top)top.location.href="frames.htm";
//-->
</script>
9. To prevent being frame
<SCRIPTLANGUAGE=javascript>
<!--
if(top.location!=self.location)top.location=self.location;
//-->
</SCRIPT>
10. Web pages will not be saved as 
<noscript><iframesrc=*.html></iframe></noscript>
11. View web source code 
<input type=button value= View web source code  onclick="window.location='view-source:'+'//www.jb51.net/">
12. How to through asp To check whether the visitor has used an agent 
<%ifRequest.ServerVariables("HTTP_X_FORWARDED_FOR")<>""then
response.write"<fontcolor=#FF0000> You go through the proxy server, "&_
" The real IP for "&Request.ServerVariables("HTTP_X_FORWARDED_FOR")
endif
%>
13. Gets the absolute position of the control 
//javascript
<scriptlanguage="javascript">
functiongetIE(e)...{
vart=e.offsetTop;
varl=e.offsetLeft;
while(e=e.offsetParent)...{
t+=e.offsetTop;
l+=e.offsetLeft;
}
alert("top="+t+" left="+l);
}
</script>
//VBScript
<scriptlanguage="VBScript"><!--
functiongetIE()
dimt,l,a,b
seta=document.all.img1
t=document.all.img1.offsetTop
l=document.all.img1.offsetLeft
whilea.tagName<>"BODY"
seta=a.offsetParent
t=t+a.offsetTop
l=l+a.offsetLeft
wend
msgbox"top="&t&chr(13)&"left="&l,64," Gets the position of the control "
endfunction
-->
</script>
14. The cursor is at the end of the text box 
<scriptlanguage="javascript">
functioncc()
...{
vare=event.srcElement;
varr=e.createTextRange();
r.moveStart('character',e.value.length);
r.collapse(true);
r.select();
}
</script>
<inputtype=textname=text1value="123"onfocus="cc()">
15. Determine the source of the previous page 
asp:
request.servervariables("HTTP_REFERER")
javascript:
document.referrer
16. Minimize, maximize, and close the window 
<objectid=hh1classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<paramname="Command"value="Minimize"></object>
<objectid=hh2classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<paramname="Command"value="Maximize"></object>
<OBJECTid=hh3classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<PARAMNAME="Command"value="Close"></OBJECT>
<inputtype=buttonvalue= To minimize the onclick=hh1.Click()>
<inputtype=buttonvalue= maximize onclick=hh2.Click()>
<inputtype=buttonvalue= Shut down onclick=hh3.Click()>
 This example applies to IE

<%
' Defines some constants for database connections 
ConstadOpenForwardOnly=0' The cursor only browses the history forward, no paging, Recordset , BookMark
ConstadOpenKeyset=1' A keyset cursor, in which changes made by other users to the record are reflected in the recordset, but additions or deletions by other users are not reflected in the recordset. Support paging, Recordset , BookMark
ConstadOpenDynamic=2' Dynamic cursors are the most powerful, but also the most resource-intensive. Any changes the user makes to the record, additions or deletions are reflected in the recordset. Support full functional browsing (ACCESS Does not support ) . 
ConstadOpenStatic=3' A static cursor is just a snapshot of the data, and any changes the user makes to the record, adding or deleting the record, are not reflected in the recordset. Supports forward or backward movement 
ConstadLockReadOnly=1' Lock type, default, read-only, cannot be changed 
ConstadLockPessimistic=2' Locking records immediately while editing is the safest way 
ConstadLockOptimistic=3' Only when called Update Method when the recordset is locked, while other operations before the current record can still be changed, inserted, deleted, and so on 
ConstadLockBatchOptimistic=4' Records are not locked while editing, and changes, inserts, and deletes are done in batch mode 
ConstadCmdText=&H0001
ConstadCmdTable=&H0002
