Question

I'm stuck here for 2 days now, and I really hope you can help me.

I'm trying to use this theme I bougth on wrapbootstrap ( https://wrapbootstrap.com/theme/ace-responsive-admin-template-WB0B30DGR ) with backboneJS and requireJS

So, basically, I have this file structure for the exemple : 

index.html
app/
 |___ js/
 |____ main.js
assets/
 |___ js
       |___ ace.min.js
       |___ ace-extra.min.js
       |___ ace-elements.min.js
       |___ bootstrap.min.js
       |___ jquery.min.js
libs
 |___ require
       |___ require.js

So, when I use this basic template : 

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="utf-8" />
    <title>Blank Page - Ace Admin</title>

    <meta name="description" content="" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />

    <!--basic styles-->

    <link href="assets/css/bootstrap.min.css" rel="stylesheet" />
    <link href="assets/css/bootstrap-responsive.min.css" rel="stylesheet" />
    <link rel="stylesheet" href="assets/css/font-awesome.min.css" />

    <!--[if IE 7]>
              <link rel="stylesheet" href="assets/css/font-awesome-ie7.min.css" />
            <![endif]-->

    <!--page specific plugin styles-->

    <!--fonts-->

    <link rel="stylesheet" href="assets/css/ace-fonts.css" />

    <!--ace styles-->

    <link rel="stylesheet" href="assets/css/ace.min.css" />
    <link rel="stylesheet" href="assets/css/ace-responsive.min.css" />
    <link rel="stylesheet" href="assets/css/ace-skins.min.css" />

    <!--[if lte IE 8]>
              <link rel="stylesheet" href="assets/css/ace-ie.min.css" />
            <![endif]-->

    <!--inline styles related to this page-->

    <!--ace settings handler-->

    <script src="assets/js/ace-extra.min.js"></script>

</head>

<body>

    <!--basic scripts-->

    <script src='assets/js/jquery-2.0.3.min.js'></script>
    <script src="assets/js/bootstrap.min.js"></script>

    <!--page specific plugin scripts-->

    <!--ace scripts-->

    <script src="assets/js/ace-elements.min.js"></script>
    <script src="assets/js/ace.min.js"></script>
</body>

</html>

No errors, all work perfectly. Then, I want, to load all the script

  1. ace-extra.min.js
  2. jquery.min.js
  3. bootstrap.min.js
  4. ace-elements.min.js
  5. ace.min.js

In this order, juste like the template.

So, I add this line in the head 

<script async data-main="app/main" src="libs/require/require.js"></script>

and created the main.js like this : 

require.config({
    // The shim config allows us to configure dependencies for
    // scripts that do not call define() to register a module
    shim: {
        bootstrap: {
            deps: ['jquery']
        },
        ace: {
            deps: ['aceElement']
        },
        aceElement: {
            deps: ['aceExtra', 'bootstrap', 'jquery']
        }
    },
    paths: {
        jquery: '../assets/js/uncompressed/jquery-2.0.3',
        bootstrap: '../assets/js/uncompressed/bootstrap',
        ace: '../assets/js/uncompressed/ace',
        aceExtra: '../assets/js/uncompressed/ace-extra',
        aceElement: '../assets/js/uncompressed/ace-elements'
    }
});
require([
    'jquery',
    'bootstrap',
    'ace'
], function() {

});

and I remove all the scripts, so I have this : 

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8" />
        <title>Blank Page - Ace Admin</title>

        <meta name="description" content="" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0" />

        <!--basic styles-->

        <link href="assets/css/bootstrap.min.css" rel="stylesheet" />
        <link href="assets/css/bootstrap-responsive.min.css" rel="stylesheet" />
        <link rel="stylesheet" href="assets/css/font-awesome.min.css" />

        <!--[if IE 7]>
          <link rel="stylesheet" href="assets/css/font-awesome-ie7.min.css" />
        <![endif]-->

        <!--page specific plugin styles-->

        <!--fonts-->

        <link rel="stylesheet" href="assets/css/ace-fonts.css" />

        <!--ace styles-->

        <link rel="stylesheet" href="assets/css/ace.min.css" />
        <link rel="stylesheet" href="assets/css/ace-responsive.min.css" />
        <link rel="stylesheet" href="assets/css/ace-skins.min.css" />

        <!--[if lte IE 8]>
          <link rel="stylesheet" href="assets/css/ace-ie.min.css" />
        <![endif]-->

        <!--inline styles related to this page-->

        <!--ace settings handler-->
    <script async data-main="app/main" src="libs/require/require.js"></script>
    </head>

    <body>
              ...
    </body>
</html>

but here, I have an error 

     Uncaught TypeError: Object #<Object> has no method 'handle_side_menu'

comes from here : 

jQuery(function($) {
    //ace.click_event defined in ace-elements.js
    ace.handle_side_menu(jQuery);

    ace.enable_search_ahead(jQuery);    

    ace.general_things(jQuery);//and settings

    ace.widget_boxes(jQuery);

    /**
    //make sidebar scrollbar when it is fixed and some parts of it is out of view
    //>> you should include jquery-ui and slimscroll javascript files in your file
    //>> you can call this function when sidebar is clicked to be fixed
    $('.nav-list').slimScroll({
        height: '400px',
        distance:0,
        size : '6px'
    });
    */
});

despite of this generated code, (Chrome dev tool) : 

    <html lang="en"><head>
        <meta charset="utf-8">
        <title>Blank Page - Ace Admin</title>

        <meta name="description" content="">

    </script></head>

    <body style=""></body></html>

So, I really don't understand, I would be really happy if anyone have an answer. Thansk !

So, it turns out it's the order in which you are doing things in the ace.min.js file. To fix it, just move your second jQuery function which contains the ace.handle_side_menu to the bottom of your ace.min.js file. It is a bit of a coincidence, but here's why.

When require loads your main.js file, it starts asynchronously loading your js files. This gives the rest of the page and DOM a chance to load (which is precisely why we like require.js). By the time your ace.min.js file gets loaded, the window has already signalled the onReady event. So, in your ace file where you have 

jQuery(function($) {
    ace.handle_side_menu(jQuery);

jQuery immediately realizes the DOM is ready and immediately calls the function you're passing in (the function($) part). This function then starts to run before handle_side_menu gets attached to the ace object. If you use the Chrome debugger tools and place breakpoints on both places where you have handle_side_menu , you'll see that the one inside the jQuery callback gets hit first.

dude, it's a coincidence. I used the same theme for my project, you can look into my html template:

https://github.com/pjyong/chenxi/blob/master/src/ChenXi/MainBundle/Resources/views/Default/index.html.twig

and my main JS file:

https://github.com/pjyong/chenxi/blob/master/web/app/js/main.js

If you have more questions, I will answer them.
