Support for multiple browsers (IE, Firefox, Opera) clipboard copy function revision _javascript tips

Be aware that Firefox must be set under
Signed.applets.codebase_principal_support
in the Firefox browser address bar input About:config Filter input Signed.applets.codebase_principal_support Double-click set to True to support. Because Firefox by default does not support scripting operations on the Clipboard.
because browsers that are just not supported are the safest browsers.

<script> function CopyToClipboard (TXT) {if (window.clipboarddata) {window.clipboardData.clearData (); Window.clipboardData.setData ("Text", txt); Alert ("Copy succeeded!") "); else if (navigator.userAgent.indexOf ("Opera")!=-1) {window.location = txt; else if (Window.netscape) {try {netscape.security.PrivilegeManager.enablePrivilege ("Universalxpconnect"); catch (E) {alert ("Your Firefox security restrictions restrict you from clipboard operation, open ' About:config ' to set Signed.applets.codebase_principal_support ' to True" Then try again, can refer to http://www.jb51.net/article/16705.htm "); return false; var clip = components.classes["@mozilla.

Here's how IE Firefox reads the information in the Clipboard

Copy Code code as follows:

function Getclipboard ()
{
if (Window.clipboarddata)
{
Return (Window.clipboardData.getData (' text '));
}
Else
{
if (Window.netscape)
{
Try
{
Netscape.security.PrivilegeManager.enablePrivilege ("Universalxpconnect");
var clip = components.classes["@mozilla. Org/widget/clipboard;1"].createinstance ( Components.interfaces.nsIClipboard);
if (!clip)
{
Return
}
var trans = components.classes["@mozilla. Org/widget/transferable;1"].createinstance ( Components.interfaces.nsITransferable);
if (!trans)
{
Return
}
Trans.adddataflavor ("Text/unicode");
Clip.getdata (trans, clip.kglobalclipboard);
var str = new Object ();
var len = new Object ();
Trans.gettransferdata ("Text/unicode", str, len);
}
catch (E)
{
Alert ("Your Firefox security restrictions restrict your clipboard operations, please open ' about:config ' to Signed.applets.codebase_principal_support ' set to True ') and try again," The relative path is the Firefox root directory/greprefs/all.js ");
return null;
}
if (str)
{
if (Components.interfaces.nsISupportsWString)
{
str = str.value.QueryInterface (Components.interfaces.nsISupportsWString);
}
Else
{
if (Components.interfaces.nsISupportsString)
{
str = str.value.QueryInterface (Components.interfaces.nsISupportsString);
}
Else
{
str = NULL;
}
}
}
if (str)
{
Return (str.data.substring (0, LEN.VALUE/2));
}
}
}
return null;
}

Here is the code to write the Clipboard under Ie,firefox

Copy Code code as follows:

Copy2clipboard=function (TXT) {
if (window.clipboarddata) {
Window.clipboardData.clearData ();
Window.clipboardData.setData ("Text", txt);
}
else if (navigator.userAgent.indexOf ("Opera")!=-1) {
Window.location=txt;
}
else if (Window.netscape) {
try{
Netscape.security.PrivilegeManager.enablePrivilege ("Universalxpconnect");
}
catch (e) {
Alert ("Your Firefox security restrictions restrict your clipboard operations, please open ' about:config ' to Signed.applets.codebase_principal_support ' set to True ') and try again," The relative path is the Firefox root directory/greprefs/all.js ");
return false;
}
var clip=components.classes[' @mozilla. Org/widget/clipboard;1 '].createinstance ( Components.interfaces.nsIClipboard);
if (!clip) return;
var trans=components.classes[' @mozilla. Org/widget/transferable;1 '].createinstance ( Components.interfaces.nsITransferable);
if (!trans) return;
Trans.adddataflavor (' Text/unicode ');
var str=new Object ();
var len=new Object ();
var str=components.classes["@mozilla. Org/supports-string;1"].createinstance ( Components.interfaces.nsISupportsString);
var Copytext=txt;str.data=copytext;
Trans.settransferdata ("Text/unicode", str,copytext.length*2);
var Clipid=components.interfaces.nsiclipboard;
if (!clip) return false;
Clip.setdata (Trans,null,clipid.kglobalclipboard);
}
}
