如何包含文件夹中的所有 .js 文件？

Question

Is there any function to include all JavaScript files from a folder using JavaScript. Since I'm have plenty if .js file to include.

Answer 1

This is a really brief way to require all files (node.js-style):

var fs = require('fs');

// assuming all things are files
fs.readdirSync('path/to/dir').forEach(function(elementName) {
    require('path/to/dir' + elementName);
});

Generally though people will make an index file in the root of the folder that individually requires each file and exports the appropriate fields.

Answer 2

There isn't, as JS cannot read the file system. You could:

• Create an array of filenames
• Create a php (or other server-side) script that returns the file list and fetch the list with ajax

Once you have the list of files, you can load them with JS:

var js=document.createElement("script");
js.src=url;
document.body.appendChild(js);
