正在组合jQuery同位素过滤器

Question

有人可以帮我组合jQuery同位素过滤器吗？在示例（CodePen Link）中，顶部有按钮过滤器，下面还有一个文本搜索过滤器。每个过滤器都单独工作，但是如何进行调整，以便您可以同时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();
}) );

Answer 2

我正在寻找一种解决方案，该解决方案最初会隐藏元素项目，而不是在单击按钮或使用快速搜索时按预期进行过滤。我听不懂，请帮忙！Here's my modified fiddle最初隐藏着一个灰色的“详细信息”方块，但单击“金属”按钮时应显示该方块。

// quick search regex
var qsRegex;
var buttonFilter;

// init Isotope
var $grid = $(".grid").isotope({
  itemSelector: ".element-item",
  filter: function() {
    // hide .init-hidden html line 24
    var isHidden = $(this).hasClass("init-hidden");

    var $that = $(this);
    var searchResult = qsRegex ? $that.text().match(qsRegex) : true;
    var buttonResult = buttonFilter ? $that.is(buttonFilter) : true;

    // + isHidden
    return !isHidden && searchResult && buttonResult;
  }
});

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



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

// debounce so filtering doesn't happen every millisecond
function debounce(fn, threshold) {
  var timeout;
  threshold = threshold || 100;
  return function debounced() {
    clearTimeout(timeout);
    var args = arguments;
    var _this = this;

    function delayed() {
      fn.apply(_this, args);
    }
    timeout = setTimeout(delayed, threshold);
  };
}
