html页面获取工程名,jquery – 如何获取当前目录名并使用node.js在html页面上显示它...

实际上我在index.js文件中有一个路径名.每当我选择目录时,我都可以在node.js控制台屏幕中看到当前目录名.

现在,我想在template.html页面的文本框中显示该目录名称.有人可以帮我解决这个问题吗？

在index.js中,在这一部分我能够在控制台中看到路径名：

app.get('/files',function(req,res) \{

var currentDir = dir;

var query = req.query.path || '';

if (query) currentDir = path.join(dir,query);

console.log("browsing ",currentDir);

我的index.js：

\#!/usr/bin/env node

var http = require('http');

var \_ = require('lodash');

var express = require('express');

var fs = require('fs');

var path = require('path');

var util = require('util');

var program = require('commander');

function collect(val,memo) \{

if(val && val.indexOf('.') != 0) val = "." + val;

memo.push(val);

return memo;

program

.option('-p,--port ','Port to run the file-browser. Default value is 8088')

.option('-e,--exclude ','File extensions to exclude. To exclude multiple extension pass -e multiple times. e.g. ( -e .js -e .cs -e .swp) ',collect,\[\])

.parse(process.argv);

var app = express();

var dir = process.cwd();

app.use(express.static(dir)); //app public directory

app.use(express.static(\_\_dirname)); //module directory

var server = http.createServer(app);

if(!program.port) program.port = 8088;

server.listen(program.port);

console.log("Please open the link in your browser http://:" + program.port);

app.get('/files',currentDir);

fs.readdir(currentDir,function (err,files) \{

if (err) \{

throw err;

var data = \[\];

files

.filter(function (file) \{

return true;

\}).forEach(function (file) \{

try \{

//console.log("processing ",file);

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,file) \});

\} catch(e) \{

console.log(e);

\});

data = \_.sortBy(data,function(f) \{ return f.Name \});

res.json(data);

\});

app.get('/',res) \{

res.redirect('lib/template.html');

\});

我的template.html：

File Browser

Browse

$(document).ready(function()\{

$("\#butDiv").click(function()\{

$("\#showDiv").toggle();

\});

我的app.js：

(function($)\{

var extensionsMap = \{

".zip" : "fa-file-archive-o",".gz" : "fa-file-archive-o",".bz2" : "fa-file-archive-o",".xz" : "fa-file-archive-o",".rar" : "fa-file-archive-o",".tar" : "fa-file-archive-o",".tgz" : "fa-file-archive-o",".tbz2" : "fa-file-archive-o",".z" : "fa-file-archive-o",".7z" : "fa-file-archive-o",".mp3" : "fa-file-audio-o",".cs" : "fa-file-code-o",".c++" : "fa-file-code-o",".cpp" : "fa-file-code-o",".js" : "fa-file-code-o",".xls" : "fa-file-excel-o",".xlsx" : "fa-file-excel-o",".png" : "fa-file-image-o",".jpg" : "fa-file-image-o",".jpeg" : "fa-file-image-o",".gif" : "fa-file-image-o",".mpeg" : "fa-file-movie-o",".pdf" : "fa-file-pdf-o",".ppt" : "fa-file-powerpoint-o",".pptx" : "fa-file-powerpoint-o",".txt" : "fa-file-text-o",".log" : "fa-file-text-o",".doc" : "fa-file-word-o",".docx" : "fa-file-word-o",\};

function getFileIcon(ext) \{

return ( ext && extensionsMap\[ext.toLowerCase()\]) || 'fa-file-o';

var currentPath = null;

var options = \{

"bProcessing": true,"bServerSide": false,"bPaginate": false,"bAutoWidth": false,"sScrollY":"250px","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();

\});
