jQuery newbie doubts

[Nakataa Kokuyo]

Good day,

could anyone here please enlighten me what is "function ()" means from below ?

$(document).ready( function () {

    
 });

Thank you !

It's a function literal, also known as an inline function or an anonymous function. It creates a new unnamed function.

By the way, there's a more commonly used shortcut for creating a ready handler, and that's to pass an inline function to the $ function:

$( function(){ /* code goes here */ } );

Thanks Bear ! another questions, how can i call the inner function "mytest" from input like button and other ?

$(document).ready( function () {  
  
function mytest(){
  alert('on click ....');
}
      
 });

I'd recommend you take some time and do a little reading. Here, for example. This will answer a lot of these "jQuery 101" type questions. Bear's book is also a great read if you can pick it up.

$(document).ready( function () {    
    
  function mytest(){  
    alert('on click ....');  
  }

  $('button').click(mytest);  
        
});    

Or better yet

$(document).ready( function () {    
  $('button').click(function() {
    alert('on click...);
  });    
});
