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
1 <!doctype html>
2 <html>
3 <head>
4 <meta charset="utf-8">
5 <title>复制文本</title>
6 </head>
7
8 <body>
9 <input type="button" value="按钮" />
10 <script src="jquery-1.10.2.min.js"></script>
11 <script>
12 $(function(){
13 $("#d_clip_button").click(function(){
14 var Url = "https://www.taobao.com/";
15 copyToClipboard(Url);
16 });
17 });
18
19 function copyToClipboard(maintext){
20 if (window.clipboardData){
21 window.clipboardData.setData("Text", maintext);
22 }else if (window.netscape){
23 try{
24 netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
25 }catch(e){
26 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～");
27 }
28 var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
29 if (!clip) return;
30 var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
31 if (!trans) return;
32 trans.addDataFlavor('text/unicode');
33 var str = new Object();
34 var len = new Object();
35 var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
36 var copytext=maintext;
37 str.data=copytext;
38 trans.setTransferData("text/unicode",str,copytext.length*2);
39 var clipid=Components.interfaces.nsIClipboard;
40 if (!clip) return false;
41 clip.setData(trans,null,clipid.kGlobalClipboard);
42 }
43 alert("以下内容已经复制到剪贴板" + maintext);
44 }
45 </script>
