Events

Event binding

jQuery event binding

Bind events with jQuery with standard jQuery event methods .on(), .off(), and .one().

// jQuery
var $grid = $('.grid').isotope({...});

function onArrange() {
  console.log('arrange done');
}
// bind event listener
$grid.on( 'arrangeComplete', onArrange );
// un-bind event listener
$grid.off( 'arrangeComplete', onArrange );
// bind event listener to be triggered just once. note ONE not ON
$grid.one( 'arrangeComplete', function() {
  console.log('arrange done, just this one time');
});

jQuery event listeners have an event argument, whereas vanilla JS listeners do not.

// jQuery, has event argument
$grid.on( 'arrangeComplete', function( event, filteredItems ) {
  console.log( filteredItems.length );
});

// vanilla JS, no event argument
iso.on( 'arrangeComplete', function( filteredItems ) {
  console.log( filteredItems.length );
});

Vanilla JS event binding

Bind events with vanilla JS with .on(), .off(), and .once() methods.

// vanilla JS
var iso = new Isotope( '.grid', {...});

function onArrange() {
  console.log('arrange done');
}
// bind event listener
iso.on( 'arrangeComplete', onArrange );
// un-bind event listener
iso.off( 'arrangeComplete', onArrange );
// bind event listener to be triggered just once
iso.once( 'arrangeComplete', function() {
  console.log('arrange done, just this one time');
});
