javascript - 同位素-组合按钮和UI滑块不起作用

我试图让Isotope插件同时使用组合按钮和UI滑块进行过滤，但不确定如何去做。

谁能帮我解决这个问题。

试一试吧。 See my demo on CodePen

诀窍是使用filter function for Isotope。除了更改过滤器，我们还可以更改过滤器逻辑中使用的值。对于此演示，我们有两个值：buttonFilter和sliderValue。我已设置过滤器功能，以检查该项目是否与buttonFilter匹配，并且其文本值大于或等于sliderValue。

// external js: isotope.pkgd.js

$(document).ready( function() {

  var sliderValue = 180;

  // create the slider;
  var rangeSlider = document.getElementById('slider-range');

  noUiSlider.create(rangeSlider, {
    start: [ 180 ],
    range: {
      'min': [  180 ],
      'max': [ 300 ]
    }
  });

  // create the slider range value;
  var rangeSliderValueElement = document.getElementById('slider-range-value');

  rangeSlider.noUiSlider.on('update', function( values, handle ) {
    rangeSliderValueElement.innerHTML = values[handle] + " cm";
  });


  // store filter for each group
  var buttonFilters = {};
  var buttonFilter = '*';

  // init Isotope
  var $grid = $('.grid').isotope({
    itemSelector: '.color-shape',
    // use filter function
    filter: function() {
      var $this = $(this);
      var isMinSize = parseFloat( $this.text() ) >= sliderValue;
      return $this.is( buttonFilter ) && isMinSize;
    }
  });

  $('.filters').on( 'click', '.button', function() {
    var $this = $(this);
    // get group key
    var $buttonGroup = $this.parents('.button-group');
    var filterGroup = $buttonGroup.attr('data-filter-group');
    // set filter for group
    buttonFilters[ filterGroup ] = $this.attr('data-filter');
    // combine filters
    buttonFilter = concatValues( buttonFilters ) || '*';
    console.log( buttonFilter )
    // set filter for Isotope
    $grid.isotope();
  });

  // filter isotope on slider set
  rangeSlider.noUiSlider.on( 'set', function( textValues, handle, values ) {
    sliderValue = values[ handle ];
    $grid.isotope();
  });

  // 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');
    });
  });

});

// flatten object by concatting values
function concatValues( obj ) {
  var value = '';
  for ( var prop in obj ) {
    value += obj[ prop ];
  }
  return value;
}
