jQuery Fundamental - I : Exercise-48

Fire a list of callbacks with a specific context and an array of arguments.

Sample solution :

HTML Code :

<!DOCTYPE html>
  <html>
  <head>
  <script src="https://code.jquery.com/jquery-git.js"></script>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>Fire a list of callbacks with a specific context and an array of arguments.</title>
  </head>
  <body>
</body>
  </html>

JavaScript Code :

// A sample  function f1
var f1 = function( value ) {
  console.log( "f1:" + value );
};
 
var callbacks = $.Callbacks();
 
// Add the function "f1" to the list
callbacks.add(f1);
 
// Fire the items on the list
callbacks.fire("JavaScript" ); 
callbacks.fire( "jquery" ); 
 
// Test if the callbacks have been called
console.log( callbacks.fired() );

Previous: Using jQuery check if the callbacks have already been called at least once.
Next: Check if a callback list contains a specific callback.
