I’m working on a jQuery widget that internally uses Backbone.js.
Here the collection creates the models, the view creates its own subviews:

Serializer = function(options, element){
  this.element = element;
  this.data = options.data;
  this.collection = new Serialize.Collection(this.data);
  this.view = new Serialize.View({ el: this.element, collection: this.collection });
};

$  .widget.bridge("serialize", Serializer);

$ .widget.bridge provides a friendly wrapper for creating instances of the widget and passing in options (here the @vars are set by Rails):

$  ('#item').serialize({
   data: <%= @data %>,
   name: '<%= @name %>',
   keys: '<%= @keys %>'
 });

The models and views created later need access to the options of the widget instance. I solved this so far by setting the options on the collection itself:

this.collection = new Serialize.Collection(this.data, options);

And referencing them later where they are needed (e.g. in a view):

var keys = this.model.collection.keys

But this gets messy and is not that flexible.

For a single instance you could set Serialize.Config = { // options }, and access it globally. But for multiple instances, each instance needs its own config.

So my question is, is there a clean way to access the widget instance and its options within the Backbone classes, without passing it as an argument?

Hello Stackoverflow users,

I have a question regarding an JQ UI widget im trying to make.
I have a _create command with the following:

    this.findinput =    this.element.children('input:text')
                            .addClass('ui-search-input ui-widget ui-state-default ui-background-none ui-corner-left')
                            .wrap('<div class="ui-position-wrapper" />')
                            .bind('focusin focusout',this._checkval)
                            .bind('keyup',this.inputchanged);

As you can see i bind some function to the input field, so i can manipulate the text and layout.
But my problem is that the function is for some reason overwriting the globa object ‘this’ and its variables.
How can i keep them inside the functions?
(The reason i use functions is so i can acces them from outside the widget)

inputchanged: function(e) {
    $  target = $  (e.target);
    if (($  target.val()).length != 0) {
        this.element.children('.ui-search-reset').children().addClass('ui-icon').removeClass('ui-helper-hidden');
    } else {
        this.element.children('.ui-search-reset').children().addClass('ui-helper-hidden').removeClass('ui-icon');
    }
},

returns: this.element is undefined and i cant acces this.options either?

Also if i bind a function to a “tr” in a table, and press the “td” it sets the “td” as the target object instead of the “tr”, which where the one binded – why is this?

Im quite new to jQuery so this might be stupid questions, or i might be doing it wrong – please let me know if that is the case!

I’ve got a form that uses the jquery autocomplete UI plugin, http://jqueryui.com/demos/autocomplete/, which all works sweet except when you press the enter key to select an item in the autocomplete list, it submits the form.

I’m using this in a .NET webforms site, so there may be javascript handling associated with the form that .NET is injecting that is overriding the jQuery stuff (I’m speculating here).

My setup: jQuery 1.6.2, jQuery UI 1.8.15

I got the selectable interaction to work but unfortunately I have links in the element itself that need to be clickable. Right now, it’s not possible to do that selectable interaction, does anyone know if there is a workaround?
