Question

我刚开始使用head.js与依赖项异步加载JS文件。

查看API文档和示例，我看到您可以将标签应用于JS文件，然后在加载时运行一些条件，这是他们文档中的一个示例：

// same as above, but pass files in as an Array
head.load([
    { label1: "file1.js" }, 
    { label2: "file2.js" }], 
    function() {
    // do something
});

// Labels are usually used in conjuntion with: head.ready()
head.ready("label1", function() {
    // do something
});

所以基本上，当加载file1.js时，它将执行第二个代码块（在闭包内）中的任何内容。

我想要做的是，在加载其他文件时加载更多文件（异步）。

例如......

首先，加载jquery文件：jquery.min.ks
成功加载后，异步加载DataTables文件：[dataTables.searchHighlight.min.js，dataTables.conditionalPaging.js，jquery.dataTables.yadcf.js]
之后，加载主应用程序文件：[myapp_core.js，myapp_whatever.js]

继承我现在的代码，使用head.js，它似乎工作正常，但它似乎不正确（必须在其他函数中抛出head.load（））

// Step #1
head.load(
    // First, load the main JS library
    [
        { jquery_core: "/include/plugins/jquery-1.11.3/jquery-1.11.3.min.js" },
        { jquery_ui: "/include/plugins/jquery-ui-1.10.4/ui/minified/jquery-ui.min.js" }
    ],
    function() {
        console.debug('Loaded jQuery library files, loading jQuery plugin files..');
        jquery_plugins();
    }
);


// Step #2
function jquery_plugins() {
    head.load([
            // Load all the jQuery plugin files
            "/include/plugins/bootstrap-3.2.0/js/bootstrap.min.js",

            console.log('All jQuery plugins loaded, loading APP js files...');
            APP_js_files();

            $.ajaxSetup({
                cache:false
            });

            App.init();


            template.init();
            account.init();
            admin.init();
            assets.init();
            forms.init();
        });
}

上面的代码在init.js中，通过..

<script type="text/javascript" src="/include/js/head.min.js" data-headjs-load="/include/js/init.js"></script>

这是正确的方法吗？ head.js上的文档非常有限。

目前的实施不支持查询或加载顺序，因为我可以在源代码中查找，这就是为什么您的问题解决方案是最好的解决方案之一。

使用head.js设置依赖项
