    Default Answered: MVC Special Key Listener

    Answered: MVC Special Key Listener


    How do you listen for a special key using a controller in MVC architecture?

    For example, if I have a form, how would I make something like this work:

    Code:
    init: function() {
            	this.control({         
    			'form': {
    				specialkey: this.key
    			}
    		});
    	},
      
    	key: function() {
    		console.log('hello');
    	}
    Thanks!

  2. The form panel itself doesn't have a specialkey event that you can listen to. But, the form fields that you'd put into a form panel often times do. So, you could listen to say all of the textfields or all of the combobox's specialkey events. Or, (untested) you might be able to listen to all of form's child items' specialkey events:

    Code:
    init: function() {
            this.control({         
    		'form > textfield': {
    			specialkey: this.key
    		}
    	});
    },
      
    key: function() {
    	console.log('hello');
    }
    (I think this works, but didn't test it)
    Code:
    init: function() {
            this.control({         
    		'form > *': {
    			specialkey: this.key
    		}
    	});
    },
      
    key: function() {
    	console.log('hello');
    }
