Jscript有些属性其实挺好的,可惜就是只是IE支持,比如复制和粘贴的属性
下面这段复制和粘贴的JAVASCRIPT的代码倒是可以支持IE/FireFox/mozilla/ns,,老外站点上看来的
只是在firefox下需要修改一下about:config的一个属性
script language="javascript" type="text/javascript"!--function copy_clip(meintext){ if (window.clipboardData) { // the IE-manier window.clipboardData.setData("Text", meintext); // waarschijnlijk niet de beste manier om Moz/NS te detecteren; // het is mij echter onbekend vanaf welke versie dit precies werkt: } else if (window.netscape) { // dit is belangrijk maar staat nergens duidelijk vermeld: // you have to sign the code to enable this, or see notes below netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect'); // maak een interface naar het clipboard var clip = Components.classes['@mozilla.org/widget/clipboard;1'] .createInstance(Components.interfaces.nsIClipboard); if (!clip) return; // maak een transferable var trans = Components.classes['@mozilla.org/widget/transferable;1'] .createInstance(Components.interfaces.nsITransferable); if (!trans) return; // specificeer wat voor soort data we op willen halen; text in dit geval trans.addDataFlavor('text/unicode'); // om de data uit de transferable te halen hebben we 2 nieuwe objecten // nodig om het in op te slaan 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("Following info was copied to your clipboard:nn" + meintext); return false;}//--/script
notes about security:
(本文来源于图老师网站,更多请访问https://m.tulaoshi.com/webkaifa/)a cause of the tight security settings in mozilla you have to sign the javascript to make it work another way is to change your firefox/mozilla settings
to do this add this line to your prefs.js file in your firefox/mozilla user profile directory
user_pref("signed.applets.codebase_principal_support", true);
or change it from within the browser with calling the "about:config" page
