jQuery (Isotope) - Combination Filtering and Sorting

Question

I'm having trouble sorting using the jQuery Isotope library. Simply, it doesn't sort.

Taking the isotope example here for multiple checkboxes from here. So to aid sorting I add some data to each div for us to sort. Working with the given example on sorting, try to add this functionality. But I can't even get Isotope's sort function to work, even at the beginning during the document ready. Any ideas why it wouldn't sort?

Here is my example code: http://codepen.io/anon/pen/YXVBqW,

and here is the relevant javascript:

$(function(){

  $container = $('#container');

  createContent();

  var $filterDisplay = $('#filter-display');

  $container.isotope();
  // do stuff when checkbox change
  $('#options').on( 'change', function( jQEvent ) {
    var $checkbox = $( jQEvent.target );
    manageCheckbox( $checkbox );

    var comboFilter = getComboFilter( filters );

    $container.isotope({ filter: comboFilter });

    $filterDisplay.text( comboFilter );
  });

  var $grid = $('.grid').isotope({
    itemSelector: '.item',
    layoutMode: 'fitRows',
    getSortData: {
      color: '[data-color]',
      number: '[data-number]'
    },
    // sort by color then number
    sortBy: [ 'color', 'number' ]
  });

  // bind sort button click
  $('.sort-by-button-group').on( 'click', 'button', function() {
    var sortValue = $(this).attr('data-sort-value');
    // make an array of values
    sortValue = sortValue.split(',');
    $grid.isotope({ sortBy: sortValue });
  });

  // change is-checked class on buttons
  $('.button-group').each( function( i, buttonGroup ) {
    var $buttonGroup = $( buttonGroup );
    $buttonGroup.on( 'click', 'button', function() {
      $buttonGroup.find('.is-checked').removeClass('is-checked');
      $( this ).addClass('is-checked');
    });
  });

});


var data = {
  brands: 'brand1 brand2 brand3 brand4'.split(' '),
  productTypes: 'type1 type2 type3 type4'.split(' '),
  colors: 'red blue yellow green'.split(' '),
  sizes: 'uk-size8 uk-size9 uk-size10 uk-size11'.split(' ')
};

function createContent() {
  var brand, productType, color, size;
  var items = '';
  // dynamically create content
  for (var i=0, len1 = data.brands.length; i < len1; i++) {
    brand = data.brands[i];
    for (var j=0, len2 = data.productTypes.length; j < len2; j++) {
      productType = data.productTypes[j];
        for (var l=0, len3 = data.colors.length; l < len3; l++) {
        color = data.colors[l];
        for (var k=0, len4 = data.sizes.length; k < len4; k++) {
          size = data.sizes[k];
          var itemHtml = '<div class="item ' + brand + ' ' +
            productType + ' ' + color + ' ' + size + '">' +
            '<p>' + brand + '</p>' +
            '<p>' + productType + '</p>' +
            '<p>' + size + '</p>' +
            '</div>';
            items += itemHtml;
        }
      }
    }
  }

  $container.append( items );
}


function getComboFilter( filters ) {
  var i = 0;
  var comboFilters = [];
  var message = [];

  for ( var prop in filters ) {
    message.push( filters[ prop ].join(' ') );
    var filterGroup = filters[ prop ];
    // skip to next filter group if it doesn't have any values
    if ( !filterGroup.length ) {
      continue;
    }
    if ( i === 0 ) {
      // copy to new array
      comboFilters = filterGroup.slice(0);
    } else {
      var filterSelectors = [];
      // copy to fresh array
      var groupCombo = comboFilters.slice(0); // [ A, B ]
      // merge filter Groups
      for (var k=0, len3 = filterGroup.length; k < len3; k++) {
        for (var j=0, len2 = groupCombo.length; j < len2; j++) {
          filterSelectors.push( groupCombo[j] + filterGroup[k] ); // [ 1, 2 ]
        }

      }
      // apply filter selectors to combo filters for next group
      comboFilters = filterSelectors;
    }
    i++;
  }

  var comboFilter = comboFilters.join(', ');
  return comboFilter;
}

function manageCheckbox( $checkbox ) {
  var checkbox = $checkbox[0];

  var group = $checkbox.parents('.option-set').attr('data-group');
  // create array for filter group, if not there yet
  var filterGroup = filters[ group ];
  if ( !filterGroup ) {
    filterGroup = filters[ group ] = [];
  }

  var isAll = $checkbox.hasClass('all');
  // reset filter group if the all box was checked
  if ( isAll ) {
    delete filters[ group ];
    if ( !checkbox.checked ) {
      checkbox.checked = 'checked';
    }
  }
  // index of
  var index = $.inArray( checkbox.value, filterGroup );

  if ( checkbox.checked ) {
    var selector = isAll ? 'input' : 'input.all';
    $checkbox.siblings( selector ).removeAttr('checked');


    if ( !isAll && index === -1 ) {
      // add filter to group
      filters[ group ].push( checkbox.value );
    }

  } else if ( !isAll ) {
    // remove filter from group
    filters[ group ].splice( index, 1 );
    // if unchecked the last box, check the all
    if ( !$checkbox.siblings('[checked]').length ) {
      $checkbox.siblings('input.all').attr('checked', 'checked');
    }
  }

}

Answer 1

i think its because you cannot sort class

there is no value declared. i should be like

<div class="element-item transition metal" data-category="transition">
  <p class="number">79</p>
  <h3 class="symbol">Au</h3>
  <h2 class="name">Gold</h2>
  <p class="weight">196.966569</p>
</div>
