JS复制到剪贴板兼容FF

 

最近需要做个复制到剪贴板功能，做为后发现在FF下不可用，最后按如下方式解决，请看代码：

[xhtml]  view plain copy print ?

1. <mce:script type="text/javascript"><!--  
2. function copyToClipboard(selContent) {     
3.      if(window.clipboardData) {     
4.         window.clipboardData.clearData();     
5.         window.clipboardData.setData("Text", selContent);     
6.         alert("IE下复制成功！");     
7.      } else if(navigator.userAgent.indexOf("Opera") != -1) {     
8.           window.location = selContent;     
9.      } else if (window.netscape) {     
10.           try {     
11.                netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");     
12.           } catch (e) {     
13.                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'");     
14.           }     
15.           var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);     
16.           if (!clip)     
17.                return;     
18.           var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);     
19.           if (!trans)     
20.                return;     
21.           trans.addDataFlavor('text/unicode');     
22.           var str = new Object();     
23.           var len = new Object();     
24.           var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);     
25.           var copytext = selContent;     
26.           str.data = copytext;     
27.           trans.setTransferData("text/unicode",str,copytext.length*2);     
28.           var clipid = Components.interfaces.nsIClipboard;     
29.           if (!clip)     
30.                return false;     
31.           clip.setData(trans,null,clipid.kGlobalClipboard);     
32.           alert("FF下复制成功！");     
33.      }     
34. }    
35. // --></mce:script>  
36. 测试内容：<input id="testContent" name="testContent" type="text" value="这是测试内容" style="width:200px"/>  
37. <input type="button" onclick="copyToClipboard(document.getElementById('testContent').value);" value="复制"/><br/>  
38. 粘贴测试：<input type="text" style="width:200px"/>
