<div>
Firefox/3.0.14下可以運(yùn)行<br />
Firefox/3.5.3下無效<br />
不過多考慮這一塊了。

下面是ie firefox 讀取剪切板中的信息的方法
復(fù)制代碼 代碼如下:
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("您的firefox安全限制限制您進(jìn)行剪貼板操作，請打開'about:config'將signed.applets.codebase_principal_support'設(shè)置為true'之后重試，相對路徑為firefox根目錄/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;
}
下面是 ie,firefox下 寫入剪切板的代碼
復(fù)制代碼 代碼如下:
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("您的firefox安全限制限制您進(jìn)行剪貼板操作，請打開'about:config'將signed.applets.codebase_principal_support'設(shè)置為true'之后重試，相對路徑為firefox根目錄/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);
}
}
具體的應(yīng)用，可以參考腳本之家的代碼。
