문제
I am trying to understand how to use Combination filters with Jquery BBQ Hash History.
What I want to do is have the user filter by Logos, Identity or Branding. If the user clicks Logos, I want them to then be able to subfilter by "Non-Profit, Education, Retail" etc. I know combination filters work fine without the jquery BBQ code implemented, but I would like to do both.
$optionSets.find('.filter-main a').click(function(){
var $this = $(this);
// don't proceed if already selected
if ( $this.hasClass('selected') ) {
return;
}
changeSelectedLink( $this );
// get href attr, remove leading #
var href = $this.attr('href').replace( /^#/, '' ),
// convert href into object
// i.e. 'filter=.inner-transition' -> { filter: '.inner-transition' }
option = $.deparam( href, true );
// apply new option to previous
$.extend( isotopeOptions, option );
// set hash, triggers hashchange on window
$.bbq.pushState( isotopeOptions );
isOptionLinkClicked = true;
return false;
});

See http://support.metafizzy.co/2011/isotope-combo-filters-hash-links.html
$(function(){
var $container = $('#container'),
filters = {},
// get filter from hash, remove leading '#'
filterSelector = window.location.hash.slice(1);
$('#filters a').click(function(){
// store filter value in object
// i.e. filters.color = 'red'
var $this = $(this),
name = $this.attr('data-filter-name'),
value = $this.attr('data-filter-value'),
isoFilters = [],
filterName, prop;
filters[ name ] = value;
for ( prop in filters ) {
isoFilters.push( filters[ prop ] );
}
var filterSelector = isoFilters.join('');
// trigger isotope if its ready
if ( $container.data('isotope') ) {
$container.isotope({ filter: filterSelector });
}
window.location.hash = filterSelector;
// toggle highlight
$this.parents('ul').find('.selected').removeClass('selected');
$this.parent().addClass('selected');
return false;
});
// if there was a filter, trigger a click on the
// corresponding option
if ( filterSelector ) {
var selectorClasses = filterSelector.split('.').slice(1);
$.each( selectorClasses, function( i, selectorClass ) {
$('#filters a[data-filter-value=".' + selectorClass + '"]').click();
});
}
$('#container').isotope({
itemSelector: '.item',
filter: filterSelector,
masonry: {
columnWidth: 80
}
});
});
