javascript - jQuery .add() using generated element not working -

I am trying to loop through an array, so that its values ​​can be used to create the collection of elements. Which can later be added to the DOM.

By doing this, I am using this code:

  $ (). Add ($ ('& lt; span / & gt;', {class: 'child', text: 'test'})). Attachments ('Container');   
 Or something like this ... the generated element is not added to the collection here with a simple example:   
 
 
 Just use a simple array and push your elements into your array.    var spans = new array (); Console.log (spans.length); Spans.push ($ ('& lt; span / & gt;', {class: 'child', text: 'test'})); Console.log (spans.length); $ ('. Container') attached (spread).   
 In your post-bedel you are mixing container and parent class, which is why  app ()  still does not work. Have given.
