<meta charset="utf-8">

JavaScript Code :

// A sample function f1 to be added to a callbacks list
var f1 = function( value ) {
  console.log( "f1:" + value );
};
 
var callbacks = $.Callbacks();
 
// Add f1 to the callback list
callbacks.add( f1 );
 
// Fire the items on the list, passing an argument
callbacks.fire( "JavaScript" );


// Lock the callbacks list
callbacks.lock();
 
// Try firing the items again
callbacks.fire( "jQuery" );

//As the list was locked, no items were called,
// so "jQuery" isn't logged
