使用head.js設置依賴項

Question

我剛剛開始使用head.js與依賴項異步加載JS文件。

查看API文檔和示例，我發現您可以將標簽應用於JS文件，然后在加載它們時運行某些條件，以下是其文檔中的示例：

// 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
});

因此，基本上，在加載file1.js時，它將執行第二個代碼塊中的任何內容（在閉包內部）。

我想做的是，在加載其他文件時（異步）加載更多文件。

例如..

1. 首先，加載jquery文件：jquery.min.ks
2. 在成功加載之后，異步加載DataTables文件：[dataTables.searchHighlight.min.js，dataTables.conditionalPaging.js，jquery.dataTables.yadcf.js]
3. 之后，加載主應用程序文件：[myapp_core.js，myapp_whatever.js]

這是我現在使用head.js擁有的代碼，似乎可以正常運行，但是看起來似乎不正確（必須將head.load（）放入其他函數中）

// 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",

            { ckeditor: "/include/plugins/ckeditor/ckeditor.js" }
        ],
        function() {
            console.log('All jQuery plugins loaded, loading APP js files...');
            APP_js_files();
        });
}

// Step #3
function APP_js_files(){
    head.load([
            // Load the application JS files
            { APP_plugins: "/include/js/APP_plugin.js" },
            { APP_intro: "/include/js/APP_intro.js" },
            { APP_app: "/include/js/APP_app.js" },
            { APP_confirmation: "/include/js/APP_confirmation.js" }
        ],
        function() {
            "use strict";
            console.log('Successfully loaded all APP js files!');

            $.ajaxSetup({
                cache:false
            });

            App.init();


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

上面的代碼位於init.js中，該文件是通過..加載的

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

這是正確的方法嗎？ head.js的文檔非常有限。

謝謝

當前的實現不支持查詢或加載順序，因為我可以在源代碼中找到，這就是為什么您的問題解決方案是最好的解決方案之一。
