    Default Answered: Ext equivalent to the jQuery method .live()

    Answered: Ext equivalent to the jQuery method .live()


    Does such a thing exist or will I need to roll my own?

    http://api.jquery.com/live/

    Description: Attach an event handler for all elements which match the current selector, now and in the future.

  2. You achieve it by using the delegate option:

    http://docs.sencha.com/ext-js/4-1/#!...od-addListener

    Code:
    Ext.getBody().on('click', function(){
        console.log('You clicked foo');
    }, null, {
        delegate: '.foo'
    });

    Had not seen the delegate argument, that is perfect - thanks!

    Actually, one more quick question - delegate refers to a DOM selector, is there an option or a way to have delegate use ComponentQuery instead?

    It would be easy enough to bake that myself, just asking if it's already built in.

    Is this alos a viable solution?

    Code:
    	        	Ext.util.Observable.observe(Ext.util.Observable);
    	        	
    	        	Ext.util.Observable.on('click', function(context, event, options) {
    		        	// intercept here
    	        	});

    The equivalent to live would be the controller in the MVC structure.

    Otherwise, you could instantiate the EventBus yourself.
