jQuery按钮复制文本内容

这种方法能保证文本内容被复制到windows剪切板，代码示例是复制url
 <!doctype html>

 <html>

     <head>

         <meta charset="utf-8">

         <title>复制文本</title>

     </head>

     <body>

         <input type="button" value="按钮" id="d_clip_button" />

         <script src="jquery-1.10.2.min.js"></script>

         <script>

             $(function(){

                 $("#d_clip_button").click(function(){

                     var Url = "https://www.taobao.com/";

                     copyToClipboard(Url);

                 });

             });

             function copyToClipboard(maintext){

                 if (window.clipboardData){

                     window.clipboardData.setData("Text", maintext);

                 }else if (window.netscape){

                     try{

                         netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");

                     }catch(e){

                         alert("该浏览器不支持一键复制！n请手工复制文本框链接地址～");

                     }

                     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=maintext;

                     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("以下内容已经复制到剪贴板" + maintext);

             }

         </script>

     </body>
