我正在尝试创建一个网页,用来显示文件树。我选择使用这个网站上的jqueryFileTree:http://www.abeautifulsite.net/blog/2008/03/jquery-file-tree/

最终,我会把这个文件树连接到一个服务器上。不过现在,我只是想在我的Windows电脑上,使用Node.js的本地服务器让它工作。

因为这个jquery插件需要一个连接脚本(用来获取目录信息),所以我选择使用他们提供的python连接脚本,jqueryFileTree.py。

我遇到的问题是,本地服务器告诉我找不到这个python脚本(错误404)。但是,我知道我提供的文件路径是正确的,因为当我在浏览器中输入这个网址时,我可以下载到这个脚本。这种情况让我感到困惑,因为它告诉我一件事,但实际却是另一回事。

下面是我所有相关的代码和信息。

目录结构:

|-public (localhost)
 |-connectors
  |-jqueryFileTree.py

创建jqueryFileTree对象的代码:

$(window).load(
function()
{
    $('#fileTree').fileTree({
        root: '/',
        script: 'connectors/jqueryFileTree.py',
        expandSpeed: 500,
        collapseSpeed: 500,
        multiFolder: true
    },
    function(file)
    {
        alert(file);
    });
});

这是我的错误信息:

Failed to load resource: the server responded with a status of 404 (Not Found): http://localhost:3700/connectors/jqueryFileTree.py

下面是jqueryFileTree和连接脚本的代码。我并不是自己写的这些代码,而是从我之前提到的网站下载插件时自带的。

我可能提供了比需要的更多信息。我想尽量详细,以免后面还要回复和补充更多信息。也就是说,如果你需要更多信息,请随时问我。

我非常感谢任何帮助!

我觉得你的问题出在这里:

script: 'connectors/jqueryFileTree.py',

你的JavaScript代码是在用户的浏览器上运行的,所以它看不到服务器上的Python文件。

相反,你应该使用Django视图可以访问的URL。可以查看Django的URL路由机制,了解如何找到与你的视图(“dirlist”)相关的URL。点击这里查看

请原谅我没有仔细检查你的脚本,也因为回复得晚。不过,我遇到过同样的问题,并且相信我通过以下链接中的方法解决了这个问题:http://pastebin.com/kVkTssdGhttp://www.abeautifulsite.net/jquery-file-tree/

具体步骤如下:

  1. 我在项目的 'node_modules' 子文件夹中创建了一个名为 'jQFTree' 的新文件夹。
  2. 我在 node.js 的 app.js 文件中添加了以下几行代码:
  3. var jQFTree=require('jQFTree');
    

    还有:

    app.post('/FileTree', jQFTree.handlePost);
    
  4. 在我的表单的 HTML 中添加了:
  5. div(id="FileTree" class="fTre")
    

    以及相应的脚本:

    var orig = window.location.origin + '/FileTree';
    var servDir='Mats';//or Carps or Rugs
    $("#FileTree").fileTree({
        root: servDir,
        script: orig
    },
    followed by callback function.
    
  6. 我之前创建的 jQFTree 文件夹里只有一个名为 'index.js' 的文件,里面有以下的 JavaScript 代码:
  7. //my Node.js module for jQuery File Tree
    var path = require('path'); 
    var fs = require('fs');
    var util = require('util');
    var stringHeader = "<ul class='jqueryFileTree' style='display: none;'>";
    var stringFooter = "</ul>";
    // arguments: path, directory name
    var formatDirectory = 
        "<li class='directory collapsed'><a href='#' rel='%s/'>%s</a><li>";
    // arguments: extension, path, filename
    var formatFile = "<li class='file ext_%s'><a href='#' rel='%s'>%s</a></li>";
    var createStatCallback = (function (res, path, fileName, isLast) {
        return function (err, stats) {
            if (stats.isDirectory()) {
                res.write(util.format(formatDirectory, path, fileName));
            }
            else {
                var fileExt = fileName.slice(fileName.lastIndexOf('.') + 1);
                res.write(util.format(formatFile, fileExt, path, fileName));
            }
            if (isLast) {
                res.end(stringFooter);
            }
        }
    });
    
    exports.handlePost = function (req, res) {
        //for safety; only directory name is available from the browser 
        //through the req.body.dir variable
        //but complete dir path in server is required for dir browsing
        // 'text/html'
        //console.log('Filetree handles post dir: '+ req.body.dir);
        res.writeHead(200, { 'content-type': 'text/plain' });
        res.write(stringHeader);
        // get a list of files
        var seeDir = req.body.dir;
        if (seeDir.indexOf('%5C') > -1 || seeDir.indexOf('%2F') > -1) {
            //directory path was returned as a subfolder from jQuery FileTree using URL encoding
            //decode it first:
            seeDir = decodeURIComponent(seeDir);
            //console.log('seeDir: '+seeDir+' __dirname:'+__dirname);
            if (seeDir.slice(-1) == "/" || seeDir.slice(-1) == "\\") {
                //last char either / (MS-windows) or \ (not MS-windows) is dropped
                seeDir = seeDir.slice(0, seeDir.length - 1)
                if (seeDir.indexOf('/') > -1) {
                    seeDir = seeDir + '/';
                }
                else {
                    seeDir = seeDir + '\\';
                }
            }
        }
        if (req.body.dir == 'Mats' || req.body.dir == 'Carps' || req.body.dir == 'Rugs') {
            //restricted to three sub dirs in server directory: public/MatsCarpsRugs/
            //console.log('.=%s', path.resolve('.'));
            //gives path to the above app.js calling this module (=as wanted)
            //combine path to requested directory:
            seeDir = path.join(path.resolve('.'), 'public', 'MatsCarpsRugs', req.body.dir);
            if (seeDir.indexOf('/')>-1){
                //web-browser not in ms-windows filesystem
                seeDir=seeDir+'/';
            }
            else{
                //web-browser is in ms-windows filesystem
                seeDir=seeDir+'\\';
            }
            //console.log('seeDir now: '+seeDir);
        }
        fs.readdir(seeDir, function (err, files) {
            var fileName = '';
            var path = '';
            var statCallback;
            if (files.length === 0) {
                path = util.format('%s%s', seeDir, fileName);
                statCallback = createStatCallback(res, path, fileName, true);
                fs.stat(path, statCallback);
                }
            for (var i = 0; i < files.length; i++) {
                fileName = files[i];
                path = util.format('%s%s', seeDir, fileName);
                var isLast = (i === (files.length - 1));
                statCallback = createStatCallback(res, path, fileName, isLast);
                fs.stat(path, statCallback);
    
            }
        });
    }
    

希望这些信息能帮助你或其他人找到解决方案。

试试这个方法:不要用这个路径 'connectors/jqueryFileTree.py',改用你在浏览器中下载脚本时使用的完整网址。
