NodeJs和JQuery：path错误
我正在build立一个文件浏览器到一个HTML页面。 这个文件浏览器是由JQuery和NodeJs组成的ExpressJs和DataTables。 目前的问题是，当点击一个子目录目录时，应该在被点击的子目录中search并呈现文件/目录; 但是，它会search并显示原始目录的文件/目录。 相关目录是[AppName] / Public / Assets}以下是html片段：
<body> <div class="panel panel-default mainpanel"> <div class="panel-heading"> Document Browser <span class="up"> <i class="fa fa-level-up"></i> Back </span> </div> <div class="panel-body"> <table class="linksholder" id="linksholder"> <thead> </thead> <tbody> <tr> <td> </td> </tr> </tbody> </table> </div> </div> <script> $(document).ready(function() { var table = $(".linksholder").dataTable({ "fnCreatedRow": function(nRow, aData, iDataIndex) { if (!aData.IsDirectory) return; var path = aData.Path; $(nRow).bind("click", function(e) { $.get('/files?path=' + path).then(function(data) { table.fnClearTable(); table.fnAddData(data); currentPath = path; }); e.preventDefault(); }); }, "aoColumns": [ { "sTitle": "", "mData": null, "bSortable": false, "sClass": "head0", "sWidth": "55px", "render": function (data, type, row, meta) { if (data.IsDirectory) { return "<a href='#' target='_blank'><i class='fa fa-folder'></i> " + data.Name +"</a>"; } else { return "<a href='/" + data.Path + "' target='_blank'><i class='fa " + "'></i> " + data.Name +"</a>"; } } } ], }); $.get('/files').then(function(data) { table.fnClearTable(); table.fnAddData(data); }); $(".up").bind("click", function(e){ if (!currentPath) return; var idx = currentPath.lastIndexOf("/"); var path =currentPath.substr(0, idx); $.get('/files?path='+ path).then(function(data){ table.fnClearTable(); table.fnAddData(data); currentPath = path; }); }); }); </script> </body> }这里是expressJs片段：
var express = require('express'); var routes = require('./routes'); var multer = require('multer'); var fs = require('fs'); var _ = require('lodash'); var path = require('path'); var app = express(); app.get('/files', function(req, res) { var currentDir = __dirname + '/public/assets/'; var query = req.query.path || ''; if (query) currentDir = path.join(currentDir, query); console.log("browsing ", currentDir); fs.readdir('/[AppName]/public/assets', function (err, files) { if (err) { throw err; } var data = []; files .forEach(function (file) { try { //console.log("processingile); var isDirectory = fs.statSync(path.join(currentDir,file)).isDirectory(); if (isDirectory) { data.push({ Name : file, IsDirectory: true, Path : path.join(query, file) }); } else { var ext = path.extname(file); if(program.exclude && _.contains(program.exclude, ext)) { console.log("excluding file ", file); return; } data.push({ Name : file, Ext : ext, IsDirectory: false, Path : path.join(query, file) }); } } catch(e) { console.log(e); } }); data = _.sortBy(data, function(f) { return f.Name }); res.json(data); }); });
我知道这是一个问题，调用函数“fnCreatedRow”调用的path，但我试图分析，不能指出它。 这里是输出：
browsing [AppName]/public/assets/:path [ReferenceError: program is not defined] { [Error: ENOENT: no such file or directory, stat '[AppName]/public/assets/:path/1'] errno: -2, code: 'ENOENT', syscall: 'stat', path: '[AppName]/public/assets/:path/1' }
其中这是目录[AppName]/public/assets不是[AppName]/public/assets/:path目录中的文件
