javascript - 同位素垂直标签需要在加载时显示第一项

Question

我使用 Isotop JS 在垂直选项卡中过滤和显示我的内容。在这里，我只是编辑了样式，例如在选项卡下显示单个元素。现在有一个问题:当初始加载页面时，它会显示选项卡内的所有内容。实际上，我只需要在第一次加载时显示第一项内容。

这是我的代码:

// Loads Isotope
$('#items').isotope();

// Filters out items
$('#filters a').click(function(e) {
  e.preventDefault()
  var selector = $(this).attr('data-filter');
  $('#items').isotope({
    filter: selector
  });
});

ul,
li {
  list-style: none;
  padding: 0;
  margin: 0;
}

a {
  text-decoration: none;
}

.isotop-tabs {
  border-right: 1px solid #aaa;
}

.isotop-tabs li {
  float: none;
  width: 100%;
}

.isotop-tabs li a {
  display: block;
  padding: 10px 0
}

Answer 1

在开始将第一项作为选择器传递时添加新的 isotope():

var first = $(".item:first")
$('#items').isotope({
    filter: first
});

// Filters out items
$('#filters a').click(function(e) {
    e.preventDefault()
    var selector = $(this).attr('data-filter');
    $('#items').isotope({
        filter: selector
    });
});

ul,
li {
  list-style: none;
  padding: 0;
  margin: 0;
}

a {
  text-decoration: none;
}

.isotop-tabs {
  border-right: 1px solid #aaa;
}

.isotop-tabs li {
  float: none;
  width: 100%;
}

.isotop-tabs li a {
  display: block;
  padding: 10px 0
}
