HAR

var resendHAR = function(meta) { var har = meta.har; var xhr = new XMLHttpRequest(); xhr.open(har.request.method, har.request.url, true); xhr.onreadystatechange = function() { if (xhr.readyState === 4 && xhr.status === 200) { console.log(xhr.responseText); meta.success && meta.success(xhr.responseText); } }; if (har.request.method === 'POST') { xhr.setRequestHeader('Content-Type', har.request.postData.mimeType); xhr.send(har.request.postData.text); } else { xhr.send(); } };

Extract mp3 from flv script

I have a video course. But there's only a Shon Harris (poor presentation materials), I thought it better to listen to this course on the player. The problem is that the player does not properly sort numeric file names (100 is earlier than 50). I wrote a little script on WSH, which solves these problems.

Source: SSCP_01.00.00.flv, SSCP_01.01.100.flv
Result: SSCP_0001.0000.0000.mp3, SSCP_0001.0001.0100.mp3

Command line: cscript /nologo list.wsf <folder path> > extract.bat



<job> <script> var shell = new ActiveXObject('WScript.Shell'); var fs = new ActiveXObject('Scripting.FileSystemObject'); var input = new Array(); for (var i = 0; i < WScript.Arguments.length; i++) { input.push(WScript.Arguments(0)); } with (WScript) { with (shell) { with (fs) { var folder = GetFolder(input[0]); var file; var iterator = new Enumerator(folder.Files) for (; !iterator.atEnd(); iterator.moveNext()) { file = iterator.item(); if (GetExtensionName(file.Path) == 'flv') { var baseName = GetBaseName(file.Path); if (/^(\w+)_(\d+)\.(\d+)\.(\d+)$/.test(baseName)) { var lead = function(mask, value) { return mask.substring(value.length) + value; }; var newName = RegExp.$1 + '_' + lead('0000', RegExp.$2) + '.' + lead('0000', RegExp.$3) + '.' + lead('0000', RegExp.$4) + '.mp3'; Echo('ffmpeg -i "' + file.Path + '" -acodec copy "' + BuildPath(folder.Path, newName) + '"'); } } } }}} </script> </job>

Chrome console.groupEnd bug

// 1
console.group('group 1');
console.group('group 2');
console.groupEnd('group 2');
console.log('end'); // console.groupEnd don't work without this log
console.groupEnd('group 1');
console.log('ready');

// 2
console.group('group 1');
console.group('group 2');
console.groupEnd('group 2');
console.groupEnd('group 1');
console.log('ready');

How can I close group without log?
