javascript - jQuery - What is the the difference -


I was checking one of my client's codes and came over it. 

  $ (document futures fu2 () {$ ("# id2") (function)) .bund ('click', function () {});} foo2 ();} );

What they are doing, attach the event handler inside the function and then call that function.

How does this differ from the following? 

  $ (document) .ready (function () {$ ("# id1"). Bind ('click', function () {}); $ ("# id2") Bind ('click', function () {});});

This event handlers is directly attached to the $ (document) .ready () function.

It works fine in both situations, I was wondering whether there are some performance related issues or something like a work faster or slow or it is a standard way of doing something I know

You can do the difference

Edit:

I would like to give you a

an example

On failure, there is a need to show a warning with Hello, it is wrong. having had!' You can do these two things: 

  WARNING ('hello, that was going wrong!');

or 

  function show error () {warning ('hello, that was going wrong!'); } ShowError ();

Solution 1 seems to be the easiest one

but ..... Imagine you want to show that error in 1000 places Are working on a huge project with locations now you will need to edit your message at 1000 locations instead of one place.

Or when you want to show an HTML popup instead of a warning, imagine changing it.

Expect an explanation, it makes sense, please do not tell me.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

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...
