javascript - Extend objects using functional invocation pattern. How? -


field here:

I'm reading the book of Crockford and wondering what a proven approach is Can the child's objects be used to open the base constructor object and avoid adding an option to it?

I thought I could use the prototype of my object and it appears that my current code is not possible.

You have several errors:

  • Your Constructor Function Completely Returns unrelated objects. Do not do this this (if a return statement does not exist, then the constructor stays on it)
  • Super Constructor calls in JS very comfortable You are not ugly creation MySuperclass.call (this, arg1, arg2, ...); is needed, in your case breast cal (this, spec); cat class
  • In order to immediately trigger the object using the prototype series, you need the new keyword.

    See for a certain version of your code.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
