Question

Help!

I'm super confused guys... I have no idea what I'm doing

I've been looking at RequireJS and AMD tutorials & examples all day yesterday and today and got to this point, however I think I still have a fundamental misunderstanding as to what a module is.

  • I have a bunch of functions that get called "onClick" from my HTML elements...
    1. How do I define my functions with RequireJS so that I can call them? So confused :/ Also I don't understand
    2. how to get my onLoad function to get called (in my case its $(function(), but how to I kick this off in RequireJS?)

I am using Node v0.10.12

<html>
...
<head>
<script data-main="" src="libraries/require.js"></script>
...
<script>
...
     //I really need all these javascript files for every function defined on this page...
     require(['simulatorConfiguration.js', 
              'modelConfiguration.js', 
              'libraries/jquery-1.10.2.min.js', 
              'libraries/jquery.lightbox_me.js', 
              'libraries/jquery-migrate-1.2.1.js', 
              'libraries/raphael-min.js'], function(start) { 

            $(function() {

                loadPage();  //<--- CALL LOAD PAGE, but it can't find the function
                //do some jquery stuff
            });

        });

    //function that get's called on body onload!
    define('loadPage', function loadPage()
    {
        hideAllDivs();
        //more jquery stuff...

        createModelMenu();
        //more jquery stuff...
    });

    define('hideAllDivs', function hideAllDivs()
    {
        //some UI stuff...

    });

    define('createModelMenu', function createModelMenu()
    {
        //some jquery stuff...
    });

    define('createTestMenu', function createTestMenu(model_key)
        {
        var javascriptLoc = "models/" + models[model_key].modelDir + "/testConfiguration.js";
        require([javascriptLoc], function(util) {

            showModelInformation(model_key);
            //some Jquery stuff...
        });
        });

    define('showModelInformation', function showModelInformation(model_key)
    {
        hideAllDivs();
        //some jquery stuff
    });

    define('showTest', function showTest(test_key)
    {       
        hideAllDivs();
        //some RaphaelJS stuff...
    });


    define('takeControl', function takeControl()
    {
        //some UI stuff
    });

    define('giveUpControl', function giveUpControl()
    {
        //some UI stuff...

    });
</script>
</head>
<body>
...
<li><a href="#" id="AoD" onclick="showTests(this.id)">Audio On Demand</a></li>
...
<input type="submit" value="Yes, Release Control" onclick="giveUpControl()">
....
<input type="submit" value="Take Control" onclick="takeControl()">
....
</body>

Do I need to do something like:

//function that get's called on body onload!
define('loadPage', function loadPage()
{
    return function(loadPage)
        {
            hideAllDivs();
            //more jquery stuff...

            createModelMenu();
            //more jquery stuff...
        }
});
//and call it with loadPage.loadPage(); ?

or maybe something like:

//function that get's called on body onload!
define('loadPage', function loadPage()
{
    return function()
        {
            hideAllDivs();
            //more jquery stuff...

            createModelMenu();
            //more jquery stuff...
        }
});

or

function(loadPage)?

I did look at these similar questions:

These were helpful too, but still not there yet:

I tried separating the functions into another file, so I have "index.html" and "Logic.js"... here is the gist:

Solution

The minimum code you need to (a) create and (b) load a module looks something like this:

// (a) Create two modules, 'hideAllDivs' and 'loadPage'.
define ('hideAllDivs', [], function () {
    return function() {
    };
});

define('loadPage', ['hideAllDivs'], function(hideAllDivs)
{
    return function()
        {
            hideAllDivs();
            //more jquery stuff...

            createModelMenu();
            //more jquery stuff...
        };
});

// (b) Load the loadPage module and call it.
require(['jquery-blah-blah', 'loadPage', 'anotherModule'], function($, loadPage, anotherModule) {
    $(function() {
        loadPage();
    });
});
