window.clipboardData.setData("Text", txt);
alert('恭喜,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("您的firefox安全限制限制您进行剪贴板操作,请在新窗口的地址栏里输入'about:config'然后找到'signed.applets.codebase_principal_support'设置为true'");
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);
