同位素组合过滤器，搜索和排序，凌乱和不完整

时间：2015-04-06 23:52:45

标签： jquery-isotope

我有一个使用同位素的页面。它结合了搜索框，多个组合过滤器以及最终的一些排序选项。

我在网上使用了很多例子来结合所有这些并尽可能地删除代码（非常有限的同位素知识）。

两件事 -

首先，如何进一步合并？我目前有3个独立的部分＆＃39;代码。

其次，搜索框独立于组合过滤器工作，当单击过滤器时，搜索框完全停止工作。是否可以在过滤器中包含搜索，例如我可以单击两个过滤器并在搜索中键入一个单词，它会找到与这三个过滤器匹配的任何内容？

以下是所有使用的相关代码 - 任何帮助表示赞赏。

//Init Isotope and set sort options
$( function() {

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

var $container = $('.results');
$container.isotope({
    filter: function() {
      return qsRegex ? $(this).text().match( qsRegex ) : true;
    },
    itemSelector: '.excerpt-home',
    masonry: {
    isFitWidth: true
    },
    getSortData: {
    name: '.name',
    price: function( itemElem ) {
    var price= $( itemElem ).find('.price-prop').text();
    return parseFloat( price.replace( /[\(\)]/g, '') );
    },
    distance: function( itemElem ) {
    var distance= $( itemElem ).find('.wppl-address').text();
    return parseFloat( distance.replace( /[\(\)]/g, '') );
    }
}
});
// sort items on button click
$('#sorts').on( 'click', 'button', function() {
  var sortByValue = $(this).attr('data-sort-by');
  $container.isotope({ sortBy: sortByValue });
});

// 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 filters = {};
var qsRegex;

$(function(){

  $container = $('.results');
    // 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 );
  });

});

$( function() {
  // quick search regex


  // init Isotope
  var $container = $('.results').isotope({
    itemSelector: '.excerpt-home'

  });

  // use value of search field to filter
  var $quicksearch = $('#quicksearch').keyup( debounce( function() {
    qsRegex = new RegExp( $quicksearch.val(), 'gi' );
    $container.isotope();
  }, 200 ) );

});


// debounce so filtering doesn't happen every millisecond
function debounce( fn, threshold ) {
  var timeout;
  return function debounced() {
    if ( timeout ) {
      clearTimeout( timeout );
    }
    function delayed() {
      fn();
      timeout = null;
    }
    timeout = setTimeout( delayed, threshold || 100 );
  }
}



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 ] = [];
  }

  // index of
  var index = $.inArray( checkbox.value, filterGroup );

  if ( checkbox.checked ) {

    if ( index === -1 ) {
      // add filter to group
      filters[ group ].push( checkbox.value );
    }
  } else {
    // remove filter from group
    filters[ group ].splice( index, 1 );
  }

}

答案 0 :(得分：1)

我遇到了同样的问题并找到了解决方案。要记住的主要事情是传递data-attribute和类，因为过滤器和搜索作为过滤器函数，排序有自己的功能。

我们的项目是按类型，国家，城市，州对所有度假村进行过滤和排序。所以我添加了国家，城市，州和州的课程。对于类别，我添加了度假村类型类别，以确定豪华度假村和常规度假村之间。

var qsRegex;
var buttonFilter;

// init Isotope var $container = $('.grid').isotope({ itemSelector: '.element-item', layoutMode: 'vertical', getSortData: { country: '.destination-country', state: '.destination-state', city: '.destination-city', resortType: '[data-resort-type]', typeR: '.destination-type-1', typeL: '.destination-type-2', typeAll: '.destination-type-all' }, filter: function() { var $this = $(this); var searchResult = qsRegex ? $this.text().match( qsRegex ) : true; var buttonResult = buttonFilter ? $this.is( buttonFilter ) : true; return searchResult && buttonResult; }, // sort top priority to lowest priority sortBy: ['resortType', 'country', 'state', 'city'] });

在这里你可以看到我的同位素插件怎么样。

// -------- Filter FUNCTION ----------//
$('.filter-by-button-group').on( 'click', 'button', function() {
    buttonFilter = $( this ).attr('data-filter-value');
    console.log("Filter button click",buttonFilter);
    $container.isotope();
});

// ----------- Search FUNCTION --------//
// use value of search field to filter
var $quicksearch = $('.quicksearch').keyup( debounce( function() {
    qsRegex = new RegExp( $quicksearch.val(), 'gi' );
    console.log("Search input",qsRegex);
    $container.isotope();
}) );

// ------------- Sort FUNCTION -------------//
// 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(',');
    console.log("Sorting button click",sortValue);
    $container.isotope({ 
                sortBy: ['resortType', sortValue]
            });
});

并且还具有去抖动，因此过滤不会每毫秒发生

// debounce so filtering doesn't happen every millisecond
function debounce( fn, threshold ) {
  var timeout;
  return function debounced() {
    if ( timeout ) {
      clearTimeout( timeout );
    }
    function delayed() {
      fn();
      timeout = null;
    }
    setTimeout( delayed, threshold || 100 );
  };
}

我的每个项目的HTML都是这样的

                <!-- ----------------------------------start resort item --------------------------------------------------  -->
            <li class="destination-list element-item destination-type-all destination-type-1" data-resort-type="destination-type-all   destination-type-1">
