要将文本复制到剪贴板,最简单的方法是使用剪贴板助手服务。

For copying text to the clipboard the easiest way is to use the clipboard helper service.

我的问题已解决:

这是脚本:该脚本从文本框中复制整个文本,您可以将其粘贴到 Firefox 浏览器中的任何位置。

<!-- Following script is for copy & paste function -->

<script>    

<![CDATA[
 function copyToClipboard() { 

//Select all the text/strings from the textbox.
var copytext=document.getElementById('tb').value; 

//alert(document.getElementById('tb').value + 'This is  XUL');

//An XPCOM wrapper for the data which you want to put on the clipboard.
var str = Components.classes["@mozilla.org/supports-string;1"].
createInstance(Components.interfaces.nsISupportsString);
if (!str) return false;
str.data = copytext;

//This object is the component @mozilla.org/widget/transferable;1 which implements the interface nsITransferable.

var trans = Components.classes["@mozilla.org/widget/transferable;1"].
createInstance(Components.interfaces.nsITransferable);
if (!trans) return false;

trans.addDataFlavor("text/unicode");
trans.setTransferData("text/unicode", str, copytext.length * 2);

var clipid = Components.interfaces.nsIClipboard;
var clip = Components.classes["@mozilla.org/widget/clipboard;1"].getService(clipid);
if (!clip) return false;

clip.setData(trans, null, clipid.kGlobalClipboard);

//alert(document.getElementById('tb').value + 'This is fuckin XUL');

pasteFromClip();

window.close();
} 

function pasteFromClip() { 

var clip = Components.classes["@mozilla.org/widget/clipboard;1"].getService(Components.interfaces.nsIClipboard); 
if (!clip) return false; 

var trans = Components.classes["@mozilla.org/widget/transferable;1"].createInstance(Components.interfaces.nsITransferable); 
if (!trans) return false; 
trans.addDataFlavor("text/unicode"); 

clip.getData(trans, clip.kGlobalClipboard); 
var str = new Object(); 
var len = new Object(); 
trans.getTransferData("text/unicode",str,len); 

str = str.value.QueryInterface(Components.interfaces.nsISupportsString); 
str = str.data.substring(0, len.value / 2); 
return document.createTextNode(str); 

}

</script>

My Problem is Fixed :

Here is the script: This script copy the entire text from the textbox and you can paste it anywhere in the browser Firefox.

<!-- Following script is for copy & paste function -->

<script>    

<![CDATA[
 function copyToClipboard() { 

//Select all the text/strings from the textbox.
var copytext=document.getElementById('tb').value; 

//alert(document.getElementById('tb').value + 'This is  XUL');

//An XPCOM wrapper for the data which you want to put on the clipboard.
var str = Components.classes["@mozilla.org/supports-string;1"].
createInstance(Components.interfaces.nsISupportsString);
if (!str) return false;
str.data = copytext;

//This object is the component @mozilla.org/widget/transferable;1 which implements the interface nsITransferable.

var trans = Components.classes["@mozilla.org/widget/transferable;1"].
createInstance(Components.interfaces.nsITransferable);
if (!trans) return false;

trans.addDataFlavor("text/unicode");
trans.setTransferData("text/unicode", str, copytext.length * 2);

var clipid = Components.interfaces.nsIClipboard;
var clip = Components.classes["@mozilla.org/widget/clipboard;1"].getService(clipid);
if (!clip) return false;

clip.setData(trans, null, clipid.kGlobalClipboard);

//alert(document.getElementById('tb').value + 'This is fuckin XUL');

pasteFromClip();

window.close();
} 

function pasteFromClip() { 

var clip = Components.classes["@mozilla.org/widget/clipboard;1"].getService(Components.interfaces.nsIClipboard); 
if (!clip) return false; 

var trans = Components.classes["@mozilla.org/widget/transferable;1"].createInstance(Components.interfaces.nsITransferable); 
if (!trans) return false; 
trans.addDataFlavor("text/unicode"); 

clip.getData(trans, clip.kGlobalClipboard); 
var str = new Object(); 
var len = new Object(); 
trans.getTransferData("text/unicode",str,len); 

str = str.value.QueryInterface(Components.interfaces.nsISupportsString); 
str = str.data.substring(0, len.value / 2); 
return document.createTextNode(str); 

}
