Question

所以我有一个网页，我在其中编写了一个插件，允许客户购买其他产品，但我不希望所有这些产品在进入页面时都显示出来。所以我正在寻找某种＆＃34;显示更多＆＃34;

＆＃13;

<div class="wrapper">
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 1</div>
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 2</div>
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 3</div>
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 4</div>
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 5</div>
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 6</div>
</div>

＆＃13;

因此，当我进入页面时，我正在寻找只显示3种产品的方式，但是如果按下显示更多按钮，它将显示接下来的3种产品。

我已经看过很多关于此的帖子，但我找不到与此相关的任何内容。

聚苯乙烯。如果按下＆＃34;显示更多＆＃34;可能会有动画，那就太棒了。

Answer 1

你有课，所以使用它并避免内联样式。另请使用jquery :gt()

检查以下方法

//this will execute on page load(to be more specific when document ready event occurs)
if ($('.ty-compact-list').length > 3) {
  $('.ty-compact-list:gt(2)').hide();
  $('.show-more').show();
}

$('.show-more').on('click', function() {
  //toggle elements with class .ty-compact-list that their index is bigger than 2
  $('.ty-compact-list:gt(2)').toggle();
  //change text of show more element just for demonstration purposes to this demo
  $(this).text() === 'Show more' ? $(this).text('Show less') : $(this).text('Show more');
});

.ty-compact-list {
  padding: 5px 5px 5px 0px;
  float: left;
  width: 100%;
}
.show-more {
  display: none;
  cursor: pointer;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="wrapper">
  <div class="ty-compact-list">Product 1</div>
  <div class="ty-compact-list">Product 2</div>
  <div class="ty-compact-list">Product 3</div>
  <div class="ty-compact-list">Product 4</div>
  <div class="ty-compact-list">Product 5</div>
  <div class="ty-compact-list">Product 6</div>
  <div class="show-more">Show more</div>
</div>

Answer 2

我喜欢亚历克斯提出的基于班级的方式，但你也可以这样做：

  function showFirstThree()
  {
    $('.ty-compact-list').hide();
    $('.ty-compact-list').slice(0,3).show();
  }

  function showAll(){
    $('.ty-compact-list').show();
  }

Answer 3

这是一个使用切换的非常简单的答案。

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
  $(function() { 
    $('.showmoreButton').on('click', function() { 
        $('.showmore').slideToggle("fast");
      });
  });
</script>
<div class="showmoreButton">Toggle Results</div>
<div class="wrapper">
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 1</div>
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 2</div>
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 3</div>
<div class="showmore" style="display: none;">
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 4</div>
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 5</div>
<div class="ty-compact-list" style="padding: 5px 5px 5px 0px; float: left; width: 100%;">Product 6</div>
</div>
</div>
