Javascript如何递归遍历本地文件夹
打印本地temp folder所有的文件及最后修改时间:
<html><head><script language='javascript'>var s = '';var result = [];function FileInfo(path, name,time) { this.path = path; this.name = name; this.time = time;}function showFolderFileList(folderspec){ var fso,f,fc,name; var url,str,file,filename; fso = new ActiveXObject('Scripting.FileSystemObject'); f = fso.GetFolder(folderspec); fc = new Enumerator( f.files ); for (; !fc.atEnd(); fc.moveNext( ) ) { filename = fso.GetFileName( fc.item( ) ); var file = fso.getFile(folderspec + '' + filename); var fileInfo = new FileInfo(folderspec, filename,file.DateLastModified); result.push(fileInfo); } var Collection = new Enumerator(f.SubFolders); for (Collection.moveFirst(); !Collection.atEnd(); Collection.moveNext()) { var Obj = Collection.item(); showFolderFileList(Obj.Path); } return result;}function display_result(result){ var body = document.getElementById('mtbody'); var size = result.length; var tr = document.getElementById('mtr'); for( var i =0; i < size; i++ ) { var newTr = tr.cloneNode(true); var children = newTr.children; for( var j = 0 ; j < children.length; j++) { var item = children.item(j); switch(j) { case 0: item.innerHTML = result[i].path; break; case 1: item.innerHTML = result[i].name; break; case 2: item.innerHTML = result[i].time; } } body.appendChild(newTr); }}function run(i, folder) { var list_result = showFolderFileList(’C:temp’); display_result(list_result);}</script></head><body onload = 'run(’c:temp’)'> <div id ='table'> <table border=1> <tbody id='mtbody'> <tr id='mtr'> <td>File Path</td> <td>File name</td> <td>Last Modify</td> </tr> </tbody> </table> </div></body></html>
因为使用了ActiveXobject，只能使用IE打开。
效果如下:
