我正在尝试创建一个显示文件树的网页。我选择使用这个网站的 jqueryFileTree:http ://www.abeautifulsite.net/blog/2008/03/jquery-file-tree/
最终,我会将这棵树连接到服务器。然而,现在,我正试图让它在运行 Node.js localhost 的 Windows 机器上运行。
由于这个 jquery 插件需要使用一个连接器脚本(能够提取目录信息),我选择使用他们包含的 python 连接器脚本 jqueryFileTree.py。
我的问题是本地主机告诉我找不到 python 脚本(错误 404)。但是,我知道我已经为文件提供了正确的路径,因为当我在浏览器中输入 url 时,我可以下载脚本。这种行为让我失望,因为它告诉我一件事,但做另一件事。
以下是我所有的相关代码和信息。
目录结构:
|-public (localhost)
|-connectors
|-jqueryFileTree.py
jqueryFileTree 对象的创建:
$(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 和连接器脚本的代码。我没有写代码。当您从我之前提到的网站下载插件时,它就会出现。
