var s=["Hscript.js","checkRobert.js","Hscript.js"];
for(i=0;i<s.length;i++){
  var script=document.createElement("script");

我写了一个简单的模块,它自动化了在JavaScript中进口/包含模块脚本的工作。 详细解释代码,请参阅博客帖子JavaScript需要/进口/包含模块。

// ----- USAGE -----

require('ivar.util.string');
require('ivar.net.*');
require('ivar/util/array.js');
require('http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js');

ready(function(){
    //Do something when required scripts are loaded
});

    //--------------------

var _rmod = _rmod || {}; //Require module namespace
_rmod.LOADED = false;
_rmod.on_ready_fn_stack = [];
_rmod.libpath = '';
_rmod.imported = {};
_rmod.loading = {
    scripts: {},
    length: 0
};

_rmod.findScriptPath = function(script_name) {
    var script_elems = document.getElementsByTagName('script');
    for (var i = 0; i < script_elems.length; i++) {
        if (script_elems[i].src.endsWith(script_name)) {
            var href = window.location.href;
            href = href.substring(0, href.lastIndexOf('/'));
            var url = script_elems[i].src.substring(0, script_elems[i].length - script_name.length);
            return url.substring(href.length+1, url.length);
        }
    }
    return '';
};

_rmod.libpath = _rmod.findScriptPath('script.js'); //Path of your main script used to mark
                                                   //the root directory of your library, any library.


_rmod.injectScript = function(script_name, uri, callback, prepare) {

    if(!prepare)
        prepare(script_name, uri);

    var script_elem = document.createElement('script');
    script_elem.type = 'text/javascript';
    script_elem.title = script_name;
    script_elem.src = uri;
    script_elem.async = true;
    script_elem.defer = false;

    if(!callback)
        script_elem.onload = function() {
            callback(script_name, uri);
        };
    document.getElementsByTagName('head')[0].appendChild(script_elem);
};

_rmod.requirePrepare = function(script_name, uri) {
    _rmod.loading.scripts[script_name] = uri;
    _rmod.loading.length++;
};

_rmod.requireCallback = function(script_name, uri) {
    _rmod.loading.length--;
    delete _rmod.loading.scripts[script_name];
    _rmod.imported[script_name] = uri;

    if(_rmod.loading.length == 0)
        _rmod.onReady();
};

_rmod.onReady = function() {
    if (!_rmod.LOADED) {
        for (var i = 0; i < _rmod.on_ready_fn_stack.length; i++){
            _rmod.on_ready_fn_stack[i]();
        });
        _rmod.LOADED = true;
    }
};

_.rmod = namespaceToUri = function(script_name, url) {
    var np = script_name.split('.');
    if (np.getLast() === '*') {
        np.pop();
        np.push('_all');
    }

    if(!url)
        url = '';

    script_name = np.join('.');
    return  url + np.join('/')+'.js';
};

//You can rename based on your liking. I chose require, but it
//can be called include or anything else that is easy for you
//to remember or write, except "import", because it is reserved
//for future use.
var require = function(script_name) {
    var uri = '';
    if (script_name.indexOf('/') > -1) {
        uri = script_name;
        var lastSlash = uri.lastIndexOf('/');
        script_name = uri.substring(lastSlash+1, uri.length);
    } 
    else {
        uri = _rmod.namespaceToUri(script_name, ivar._private.libpath);
    }

    if (!_rmod.loading.scripts.hasOwnProperty(script_name)
     && !_rmod.imported.hasOwnProperty(script_name)) {
        _rmod.injectScript(script_name, uri,
            _rmod.requireCallback,
                _rmod.requirePrepare);
    }
};

var ready = function(fn) {
    _rmod.on_ready_fn_stack.push(fn);
};

若要在 JavaScript 中输入另一个脚本,请使用输入关键字:

import '/src/js/example.js';

// both types of quotes work
import "/src/js/example2.js";

var js = document.createElement("script");

js.type = "text/javascript";
js.src = jsFilePath;

document.body.appendChild(js);

var xxx = require("../lib/your-library.js")

或

import xxx from "../lib/your-library.js" //get default export
import {specificPart} from '../lib/your-library.js' //get named export
import * as _name from '../lib/your-library.js'  //get full export to alias _name

您也可以使用 PHP 编写脚本:

文件 main.js.php:

<?php
    header('Content-type:text/javascript; charset=utf-8');
    include_once("foo.js.php");
    include_once("bar.js.php");
?>

// Main JavaScript code goes here
