jQuery collections, function and organisation

jQuery collections, function and organisation

I have the following code which takes a single image and applies a
specific width to it:
function Foo ( img ) {
this.image = img;
}
Foo.prototype._getWidth = function( ) {
return this.image.data('largest') + 'px';
};
Foo.prototype.applyWidth = function( ) {
this.image.css( 'width', this._getWidth() );
};
var img = Foo( $('img') );
img.applyWidth();
However I am struggling to get my head around handling a jQuery collection
of images, such as $('img') without a for loop or $.each()inside each of
the functions (I have more than these two functions shown above).
So far the best I have come up with is:
var temp = [];
function Create ( imgs ) {
$.each( imgs, function( i ){
temp[ i ] = new Foo ( $( this ) );
});
return temp;
}
Create( $('img') );
$.each( temp, function() {
$(this).applyWidth();
}):
This works fine, but it doesn't feel organised, feels sloppy.
Finally, I would like some guidance on the following.
I ideally want this under the namespace Theme. I would like this method
under Theme.Images using the module pattern. Is this possible?
If under the namespace Theme.Images would it be possible to make a call
such as Theme.Images.applyWidth() that would call applyWidth() on all the
images in temp, bearing in mind each img would have a unique value for
_getWidth(). At the moment I believe I would need to loop
Theme.Images.temp and call applyWidth() inside the loop.
I apologize in advanced for the long question, but I have been bending my
head around this for a few days. I am really starting to appreciate the
point of inheritance in javascript, and would like to continue with it.
