Question

正如我从代码中看到的那样，我正在研究同位素，我已经实现了基本的可过滤布局。现在，我想添加一些其他功能。单击可过滤的项目后，最大宽度元素应立即显示。

在代码中，如单击红色所示，您会看到它正在为我提供所需的布局（“一个大项目，下面有两个小项目”）。但是如果是蓝色，则较小的项目在较大的项目之前。

请随时澄清任何疑问。

谢谢。

您可以使用getSortData和sortBy完成此操作。

使用getSortData

定义排序时要使用的条件/值

var $grid = $('.grid').isotope({
  itemSelector: '.color-shape',
  layoutMode: 'fitRows',
  getSortData: {
      wide: function(element){return element.classList.contains('wide') ? -1 : 1}
    }
});

，并指示使用sortBy

进行排序

$('.filters').on( 'click', '.button', function( event ) {
  var filterValue = $( this ).attr('data-filter');
  var sortValue = filterValue ? 'wide' : 'original-order';
     // use filterFn if matches value
    filterValue = filterFns[ filterValue ] || filterValue;
    $grid.isotope({ filter: filterValue, sortBy: sortValue });
});

// init Isotope
var $grid = $('.grid').isotope({
  itemSelector: '.color-shape',
  layoutMode: 'fitRows',
  getSortData: {
      wide: function(element){return element.classList.contains('wide') ? -1 : 1}
    }
});

// store filter for each group
var filters = {};

var filterFns = {
  // show if number is greater than 50
  numberGreaterThan50: function() {
    var number = $(this).find('.number').text();
    return parseInt(number, 10) > 50;
  },
  // show if name ends with -ium
  ium: function() {
    var name = $(this).find('.name').text();
    return name.match(/ium$/);
  }
};
$('.filters').on( 'click', '.button', function( event ) {
  var filterValue = $( this ).attr('data-filter');
  var sortValue = filterValue ? 'wide' : 'original-order';
     // use filterFn if matches value
    filterValue = filterFns[ filterValue ] || filterValue;
    $grid.isotope({ filter: filterValue, sortBy: sortValue });
});


// change is-checked class on buttons
$('.button-group').each(function(i, buttonGroup) {
  var $buttonGroup = $(buttonGroup);
  $buttonGroup.on('click', 'button', function(event) {
    $buttonGroup.find('.is-checked').removeClass('is-checked');
    var $button = $(event.currentTarget);
    $button.addClass('is-checked');
  });
});
