支持ie与FireFox的剪切板操作代码

复制代码代码如下:<html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>支持ie与FireFox的剪切板代码</title> <script type="text/javascript"> function setCopy(_sTxt){ try{ if(window.clipboardData){ window.clipboardData.setData("Text", _sTxt); } else if(window.netscape) {//FireFox搞得真复杂呀 netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect'); 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 = _sTxt; 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); } }catch(e){} } </script> </head> <body> <input type="button" onclick="setCopy('hello');" value="复制" /> <div> Firefox/3.0.14下可以运行<br /> Firefox/3.5.3下无效<br /> 不过多考虑这一块了。 </div> </body> </html> 下面是ie firefox 读取剪切板中的信息的方法复制代码代码如下:function getClipboard() { if (window.clipboardData) { return (window.clipboardData.getData('text')); } else { if (window.netscape) { try { netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); 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"); clip.getData(trans, clip.kGlobalClipboard); var str = new Object(); var len = new Object(); trans.getTransferData("text/unicode", str, len); } catch (e) { alert("您的firefox安全限制限制您进行剪贴板操作，请打开'about:config'将signed.applets.codebase_principal_support'设置为true'之后重试，相对路径为firefox根目录/greprefs/all.js"); return null; } if (str) { if (Components.interfaces.nsISupportsWString) { str = str.value.QueryInterface(Components.interfaces.nsISupportsWString); } else { if (Components.interfaces.nsISupportsString) { str = str.value.QueryInterface(Components.interfaces.nsISupportsString); } else { str = null; } } } if (str) { return (str.data.substring(0, len.value / 2)); } } } return null; } 下面是 ie,firefox下写入剪切板的代码复制代码代码如下:copy2Clipboard=function(txt){ if(window.clipboardData){ window.clipboardData.clearData(); window.clipboardData.setData("Text",txt); } 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，请打开'about:config'将signed.applets.codebase_principal_support'设置为true'之后重试，相对路径为firefox根目录/greprefs/all.js"); 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); } }具体的应用，可以参考脚本之家的代码。
