直接运行html的代码

function runCode(pTargetId){var newWin=window.open('',"_blank",'');newWin.document.open('text/html','replace');newWin.opener=null;var testCode=document.getElementById(pTargetId).value;newWin.document.write(testCode);newWin.document.close();}function saveCode(pTargetId){var newWin=window.open('','_blank','top=10000');newWin.document.open('text/html','replace');var testCode=document.getElementById(pTargetId).value;newWin.document.write(testCode);newWin.document.execCommand('saveas','','code.htm');newWin.close();}function copyCode(pTargetId){var testCode=document.getElementById(pTargetId).value;if(copy2Clipboard(testCode)!=false){alert("生成的代码已经复制到粘贴板，你可以使用Ctrl+V 贴到需要的地方去了哦！  ");}}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");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);}}
