Question

所以我有一个php脚本从数据库生成新闻/案例帖子，重复以下HTML

    <a href='/post/placeholder'>
  <div class='col nopadding col12-12 counter'>
    <div class='col col6-12 vheight'>
      <h2>placeholder</h2>
      <p>placeholder</p>
    </div>
    <div class='col col6-12 nopadding varheight '>
      <div class='imagewrapper'>
        <img src='/public/images/images/placeholder.jpg' />
      </div>
    </div>
  </div>
</a>

我想要选择每个'计数器'类，并将.vheight的高度存储在变量中，以便.varheight（图像）总是响应相同的高度。

我目前有这个JQuery

$(window).resize(function () {
  $( ".counter" ).each(function() {
    var $counter = $(this).next('.vheight').outerHeight(true);
    $(this).next(".varheight").css("height", $counter);
  });
});

$(window).load(function () {
  $( ".counter" ).each(function() {
    var $counter = $(this).next('.vheight').outerHeight(true);
    $(".varheight").css("height", $counter);
  });
});

我似乎无法让它工作，并且已经在SO上查看了其他类似的答案。

如果您想要完成此操作，请尝试查看此内容，如果不符合您的需求，我们可以尝试进行更改。

$('.counter').each(function(){
  var myHieght = $(this).find('.vheight').height();
  $(this).find('.varheight').height(myHieght);
})

a{
  display: block;
  position: relative;
  float: left;
  width:250px;
} 
.varheight{
  position:relative
}
.imagewrapper{
  position:aboslute;
  height:100%;
  width:100%;
}
img{
  max-width:100%;
  position: absolute;
  top:0;
  left:0;
  height:100%;
  width:100%;
}

Answer 2

您正在通过find选择错误的元素，请尝试以下方法：

$(window).resize(function () {
  $( ".counter" ).each(function() {
    var $counter = $('.vheight', this).outerHeight(true);
    $('.vheight', this).css("height", $counter);
  });
});

在加载函数上执行相同的选择=＆gt; $('your next element', this)

Answer 3

使用find（）代替next（）

$( ".counter" ).each(function() {
    var $counter = $(this).find('.vheight').outerHeight(true);
    $(this).find(".varheight").css("height", $counter);
});

JQuery选择每个父项，获取child1的高度并将child2设置为child1高度
