代码如下: function copyToClipboard(meintext) { //ie if (window.clipboardData){ window.clipboardData.setData("Text", meintext); } else if (window.netscape) { try { netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); } catch(e) { alert("被浏览器拒绝！"); ///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=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); } alert("已复制本页链接,您可以使用Ctrl+V粘贴后,发送给好友!"); return false; } // -->
