{转}javascript复制到粘贴板,支持各种浏览器

点击复制到粘贴板的代码,支持各种浏览器,我只试过了IE,FF,不过在FF下会提示一段信息让你接受

[javascript]
<script type="text/javascript">
function copyToClipboard(txt) {
if(window.clipboardData) {
window.clipboardData.clearData();
window.clipboardData.setData("Text", txt);
alert("复制成功");
} else if(navigator.userAgent.indexOf("Opera") != -1) {
window.location = txt;
} else if (window.netscape) {
try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
} catch (e) {
alert("如果您正在使用FireFox!\n请在浏览器地址栏输入’about:config’并回车\n然后将’signed.applets.codebase_principal_support’设置为’true’");
}
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);
alert("复制成功!")
}
}
</script>
