感谢您的帮助。
以下是代码(目前是我的代码仅适用于IE浏览器): -
Below is the code (Currently my code is working only on IE browser):-
<script type="text/javascript">
function copyToClipboard(s)
{
if( window.clipboardData && clipboardData.setData )
{
clipboardData.setData("Text", s);
}
else
{
// You have to sign the code to enable this or allow the action in about:config by changing
user_pref("signed.applets.codebase_principal_support", true);
netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');
var clip = Components.classes['@mozilla.org/widget/clipboard;[[[[1]]]]'].createInstance(Components.interfaces.nsIClipboard);
if (!clip) return;
// create a transferable
var trans = Components.classes['@mozilla.org/widget/transferable;[[[[1]]]]'].createInstance(Components.interfaces.nsITransferable);
if (!trans) return;
// specify the data we wish to handle. Plaintext in this case.
trans.addDataFlavor('text/unicode');
// To get the data from the transferable we need two new objects
var str = new Object();
var len = new Object();
var str = Components.classes["@mozilla.org/supports-string;[[[[1]]]]"].createInstance(Components.interfaces.nsISupportsString);
var copytext=meintext;
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);
}
}
</script>
<textarea id='testText' rows="10" cols="100">Enter your Sample text</textarea><br />
<button onclick="copyToClipboard(document.getElementById('testText').value);" >clipboard</button><br /><br />
<textarea rows="10" cols="100">Paste your text here</textarea><br />
推荐答案
这适用于firefox 3.6.x和IE:
This works on firefox 3.6.x and IE:
function copyToClipboardCrossbrowser(s) {
s = document.getElementById(s).value;
if( window.clipboardData && clipboardData.setData )
{
clipboardData.setData("Text", s);
}
else
{
// You have to sign the code to enable this or allow the action in about:config by changing
//user_pref("signed.applets.codebase_principal_support", true);
netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');
var clip = Components.classes["@mozilla.org/widget/clipboard;1"].createInstance(Components.interfaces.nsIClipboard);
if (!clip) return;
// create a transferable
var trans = Components.classes["@mozilla.org/widget/transferable;1"].createInstance(Components.interfaces.nsITransferable);
if (!trans) return;
// specify the data we wish to handle. Plaintext in this case.
trans.addDataFlavor('text/unicode');
// To get the data from the transferable we need two new objects
var str = new Object();
var len = new Object();
var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
str.data= s;
trans.setTransferData("text/unicode",str, str.data.length * 2);
var clipid=Components.interfaces.nsIClipboard;
if (!clip) return false;
clip.setData(trans,null,clipid.kGlobalClipboard);
}
}
