Some common methods of javascript scripts that have just been found on the Internet.

1. oncontextmenu = "window. event. returnvalue = false" will completely block the right mouse button
<Table border oncontextmenu = return (false)> <td> no </table>

<Script language = "javascript"> <! --
If (window = top) top. location. href = "frames.htm"; // frames.htm is the frame webpage.
// --> </Script>

<Script language = javascript> <! --
If (top. location! = Self. location) top. location = self. location;
// --> </SCRIPT>

"<Noscript> <iframe> onclick =" window. location = 'view-source: '+ 'HTTP: // www.csdn.net/' ">

<% If Request. ServerVariables ("HTTP_X_FORWARDED_FOR") <> "then
Response. write "<font color = # FF0000> you have passed the proxy server ,"&_
"The real IP address is" & Request. ServerVariables ("HTTP_X_FORWARDED_FOR ")
End if
%>

<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>

<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, "Get control position"
End function
--> </Script>

<Script language = "javascript">

Asp:
Request. servervariables ("HTTP_REFERER ")

Document. referrer

<Object classid = "clsid: ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<Param value = "Minimize"> </object>
<Object classid = "clsid: ADB880A6-D8FF-11CF-9377-00AA003B7A11">

This example applies to IE

'Define some constants for database connection
Const adOpenForwardOnly = 0' the cursor only browses records forward. pagination, Recordset, and BookMark are not supported.
Const adOpenKeyset = 1' indicates the keyset cursor. modifications made by other users to the record are reflected in the record set. However, adding or deleting records by other users is not reflected in the record set. Supports paging, Recordset, and BookMark
Const adOpenDynamic = 2' the most dynamic cursor function, but the most resource consumption. The added or deleted records modified by the user on the record description will be reflected in the record set. Supports full-featured browsing (ACCESS is not supported ).
Const adOpenStatic = 3' the static cursor is only a snapshot of the data. The changes you make to the record description, adding or deleting records, will not be reflected in the record set. Supports moving forward or backward

Const adLockOptimistic = 3' the record set is locked only when the Update method is called, and other operations before this can still change, insert, and delete the current record.
Const adLockBatchOptimistic = 4' records are not locked when being edited, but changes, inserts, and deletes are completed in the batch processing mode.

Const adCmdTable = & H0002

<Div> (division) is used to define the page elements of a large segment, and a line is generated.
<Span> is used to define elements in the same row. The only difference between <div> and <div> is that no transpose is generated.
<Layer> is the ns tag, which is not supported by ie, which is equivalent to <div>

<Body>

Make the vertical bar not:
<Body style = 'overflow: scroll; overflow-y: Den den '>
</Body>
Make the horizontal bar unavailable:
<Body style = 'overflow: scroll; overflow-x: Den den '>

Remove both of them? Simpler
