Question

请任何人帮我梳理jQuery Isotope过滤器。在示例（CodePen链接）中，顶部有按钮过滤器，然后是下面的文本搜索过滤器。每个单独工作，但如何调整，以便您可以一起使用两种过滤器类型？

Answer 1

您需要使用此代码示例中的buttonFilter变量：

// quick search regex
var qsRegex;
var buttonFilter;

// init Isotope
var $container = $('.isotope').isotope({
  itemSelector: '.element-item',
  layoutMode: 'fitRows',
  filter: function() {
    var $this = $(this);
    var searchResult = qsRegex ? $this.text().match( qsRegex ) : true;
    var buttonResult = buttonFilter ? $this.is( buttonFilter ) : true;
    return searchResult && buttonResult;
  }
});

$('#filters').on( 'click', 'button', function() {
  buttonFilter = $( this ).attr('data-filter');
  $container.isotope();
});

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