ElwoodP on "Wordpress, Jquery BBQ, and Isotope"

Hi bbart10,
I've just integrated jQuery BBQ onto a site to achieve what you describe. There is an example of BBQ itnegration with Isotope here:
http://isotope.metafizzy.co/demos/hash-history.html
and a tutorial here:
http://isotope.metafizzy.co/docs/hash-history-jquery-bbq.html

I didn't find the tutorial totally usefull though since it doesn't cover how to update the Navigation. I ended up stripping the javascript out of the example page (inline at the bottom of the page):

$(function(){

      var $container = $('#container'),
          // object that will keep track of options
          isotopeOptions = {},
          // defaults, used if not explicitly set in hash
          defaultOptions = {
            filter: '*',
            sortBy: 'original-order',
            sortAscending: true,
            layoutMode: 'masonry'
          };

      // add randomish size classes
      $container.find('.element').each(function(){
        var $this = $(this),
            number = parseInt( $this.find('.number').text(), 10 );
        if ( number % 7 % 2 === 1 ) {
          $this.addClass('width2');
        }
        if ( number % 3 === 0 ) {
          $this.addClass('height2');
        }
      });

      var setupOptions = $.extend( {}, defaultOptions, {
        itemSelector : '.element',
        masonry : {
          columnWidth : 120
        },
        cellsByRow : {
          columnWidth : 240,
          rowHeight : 240
        },
        getSortData : {
          symbol : function( $elem ) {
            return $elem.attr('data-symbol');
          },
          category : function( $elem ) {
            return $elem.attr('data-category');
          },
          number : function( $elem ) {
            return parseInt( $elem.find('.number').text(), 10 );
          },
          weight : function( $elem ) {
            return parseFloat( $elem.find('.weight').text().replace( /[\(\)]/g, '') );
          },
          name : function ( $elem ) {
            return $elem.find('.name').text();
          }
        }
      });

      // set up Isotope
      $container.isotope( setupOptions );

      var $optionSets = $('#options').find('.option-set'),
          isOptionLinkClicked = false;

      // switches selected class on buttons
      function changeSelectedLink( $elem ) {
        // remove selected class on previous item
        $elem.parents('.option-set').find('.selected').removeClass('selected');
        // set selected class on new item
        $elem.addClass('selected');
      }

      $optionSets.find('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;
      });

      var hashChanged = false;

      $(window).bind( 'hashchange', function( event ){
        // get options object from hash
        var hashOptions = window.location.hash ? $.deparam.fragment( window.location.hash, true ) : {},
            // do not animate first call
            aniEngine = hashChanged ? 'best-available' : 'none',
            // apply defaults where no option was specified
            options = $.extend( {}, defaultOptions, hashOptions, { animationEngine: aniEngine } );
        // apply options from hash
        $container.isotope( options );
        // save options
        isotopeOptions = hashOptions;

        // if option link was not clicked
        // then we'll need to update selected links
        if ( !isOptionLinkClicked ) {
          // iterate over options
          var hrefObj, hrefValue, $selectedLink;
          for ( var key in options ) {
            hrefObj = {};
            hrefObj[ key ] = options[ key ];
            // convert object into parameter string
            // i.e. { filter: '.inner-transition' } -> 'filter=.inner-transition'
            hrefValue = $.param( hrefObj );
            // get matching link
            $selectedLink = $optionSets.find('a[href="#' + hrefValue + '"]');
            changeSelectedLink( $selectedLink );
          }
        }

        isOptionLinkClicked = false;
        hashChanged = true;
      })
        // trigger hashchange to capture any hash data on init
        .trigger('hashchange');

    });

I then removed a few setup bits since I already had isotope working and changed a couple of IDs and classes to match my markup. Ended up with this:

jQuery(function($){

      var $container = $('#containerp'),
          // object that will keep track of options
          isotopeOptions = {},
          // defaults, used if not explicitly set in hash
          defaultOptions = {
            filter: '*',
            sortBy: 'original-order',
            sortAscending: true,
            layoutMode: 'masonry'
          };

       var $optionSets = $('#projects').find('#filterNav'),
          isOptionLinkClicked = false;

      // switches selected class on buttons
      function changeSelectedLink( $elem ) {
        // remove selected class on previous item
        $elem.parents('#filterNav').find('.selected').removeClass('selected');
        // set selected class on new item
        $elem.addClass('selected');
      }

      $optionSets.find('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;
      });

      var hashChanged = false;

      $(window).bind( 'hashchange', function( event ){
        // get options object from hash
        var hashOptions = window.location.hash ? $.deparam.fragment( window.location.hash, true ) : {},
            // do not animate first call
            aniEngine = hashChanged ? 'best-available' : 'none',
            // apply defaults where no option was specified
            options = $.extend( {}, defaultOptions, hashOptions, { animationEngine: aniEngine } );
        // apply options from hash
        $container.isotope( options );
        // save options
        isotopeOptions = hashOptions;

        // if option link was not clicked
        // then we'll need to update selected links
        if ( !isOptionLinkClicked ) {
          // iterate over options
          var hrefObj, hrefValue, $selectedLink;
          for ( var key in options ) {
            hrefObj = {};
            hrefObj[ key ] = options[ key ];
            // convert object into parameter string
            // i.e. { filter: '.inner-transition' } -> 'filter=.inner-transition'
            hrefValue = $.param( hrefObj );
            // get matching link
            $selectedLink = $optionSets.find('a[href="#' + hrefValue + '"]');
            changeSelectedLink( $selectedLink );
          }
        }

        isOptionLinkClicked = false;
        hashChanged = true;
      })
        // trigger hashchange to capture any hash data on init
        .trigger('hashchange');

    });

Hope that helps. I'm no javascript expert but this seems to work.
