Use jQuery plugin with Backbone and Requirejs

问题:

I'm working with backbone+requirejs+jquery and I have a problem with jquery plugin loading in my current html page (backbone html template precisly).

There is my require configuration:

require.config({

  paths: {
    // ... some code about backbone config
    jquery: '/js/lib/jquery/jquery.min',
    'jquery.camera' : '/js/jquery/jquery.camera'
  },

  shim: {
    // ... some code about backbone config
    'jquery.camera': ['jquery']  
  }
});

In my layout html page I have:

<script type='text/javascript' src='/js/jquery/jquery.camera.js'></script>

and in my template page I have:

<script type="text/javascript">
  jQuery(function() {

    jQuery('#test').camera({
...
</script>

Finally my browser mesg :

Uncaught TypeError: Object [object Object] has no method 'camera'

Do you have any idea?

In the same time I have another question, what is the best way to include some js code in our current page with backbone,requirejs, etc.

Thanks :)

回答1:

I solved a similar issue (Jquery.cookie) like this, but my problem was that Jquery was being loaded and then Jquery.cookie was being included but require already had JQuery as a Static resource.

So like this I pass Jquery.Cookie to the application and it inserts jquery.cookie in my application scope only.

require.config({

  paths: {
      'async'           : 'libs/async'
      ,'jquery'         : 'libs/jquery'
      ,'underscore'     : 'libs/underscore'
      ,'backbone'       : 'libs/backbone'
      ,'text'           : 'libs/text'
      ,'jquery.cookie'  : 'libs/jquery.cookie'   // <-- cookie lives here
  }

  ,shim: {
    'jquery': {
      exports: '$'
    }
    ,'underscore': {
      exports: '_'
    }
    ,'backbone': {
      deps: ['underscore', 'jquery'],
      exports: 'Backbone'
    }
    ,'jquery.cookie': {     //<-- cookie depends on Jquery and exports nothing
        deps: ['jquery']
    }
  }
});

and then in the main App class I added

require([
  'jquery'
  ,'underscore'
  ,'backbone'
  ,'mapApp'
  ,'jquery.cookie'   //<- this is the real trick !!!
],
  function ($, _, Backbone, App) {

After this I was able to find jquery cookie.

BTW: there is no need to import JQuery.camera in your html if you are using Require.js to fetch it, unless you use it outside your Require.js scope.
