我只是写了这个JavaScript代码(使用DOM操作的Prototype):

var require = (function() {
    var _required = {};
    return (function(url, callback) {
        if (typeof url == 'object') {
            // We've (hopefully) got an array: time to chain!
            if (url.length > 1) {
                // Load the nth file as soon as everything up to the
                // n-1th one is done.
                require(url.slice(0, url.length - 1), function() {
                    require(url[url.length - 1], callback);
                });
            } else if (url.length == 1) {
                require(url[0], callback);
            }
            return;
        }
        if (typeof _required[url] == 'undefined') {
            // Haven't loaded this URL yet; gogogo!
            _required[url] = [];

            var script = new Element('script', {
                src: url,
                type: 'text/javascript'
            });
            script.observe('load', function() {
                console.log("script " + url + " loaded.");
                _required[url].each(function(cb) {
                    cb.call(); // TODO: does this execute in the right context?
                });
                _required[url] = true;
            });

            $$('head')[0].insert(script);
        } else if (typeof _required[url] == 'boolean') {
            // We already loaded the thing, so go ahead.
            if (callback) {
                callback.call();
            }
            return;
        }

        if (callback) {
            _required[url].push(callback);
        }
    });
})();

使用:

<script src="prototype.js"></script>
<script src="require.js"></script>
<script>
    require(['foo.js','bar.js'], function () {
        /* Use foo.js and bar.js here */
    });
</script>

保持它好,短,简单,可持续的! :]

// Third-party plugins / script (don't forget the full path is necessary)
var FULL_PATH = '', s =
[
    FULL_PATH + 'plugins/script.js'      // Script example
    FULL_PATH + 'plugins/jquery.1.2.js', // jQuery Library
    FULL_PATH + 'plugins/crypto-js/hmac-sha1.js',      // CryptoJS
    FULL_PATH + 'plugins/crypto-js/enc-base64-min.js'  // CryptoJS
];

function load(url)
{
    var ajax = new XMLHttpRequest();
    ajax.open('GET', url, false);
    ajax.onreadystatechange = function ()
    {
        var script = ajax.response || ajax.responseText;
        if (ajax.readyState === 4)
        {
            switch(ajax.status)
            {
                case 200:
                    eval.apply( window, [script] );
                    console.log("library loaded: ", url);
                    break;
                default:
                    console.log("ERROR: library not loaded: ", url);
            }
        }
    };
    ajax.send(null);
}

// Initialize a single load
load('plugins/script.js');

// Initialize a full load of scripts
if (s.length > 0)
{
    for (i = 0; i < s.length; i++)
    {
        load(s[i]);
    }
}

这个代码只是一个短暂的功能例子,可能需要额外的功能功能,以便在任何(或提供)平台上提供完整的支持。

可以动态地创建一个JavaScript标签并将其添加到来自其他JavaScript代码的HTML文档中,这将加载针对JavaScript文件。

function includeJs(jsFilePath) {
    var js = document.createElement("script");

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

    document.body.appendChild(js);
}

includeJs("/path/to/some/file.js");

这里是一个基本插件,允许您使用 @import “path/to/file.js”; syntax 在任何文件中,包括JavaScript文件。

它可以通过 npm 安装安装: https://npmjs.org/package/grunt-import

不要忘了查看LAB.js!

<script type="text/javascript">
  $LAB.script("jquery-1.8.3.js").wait().script("scripts/clientscript.js");      
</script>

var s=["Hscript.js","checkRobert.js","Hscript.js"];
for(i=0;i<s.length;i++){
  var script=document.createElement("script");
  script.type="text/javascript";
  script.src=s[i];
  document.getElementsByTagName("head")[0].appendChild(script)
};
