Question

我需要在正确的div高度增加的情况下自动调整左div的高度。

我的CSS和HTML代码在这里

.left {
margin:auto;
float:left;
width:30%;
height:auto;
background:#000;
}
.right {
margin:auto;
float:left;
width:70%;
height:auto;
background:#eee;
}

<div class="left">sgdsfhdh</div>
<div class="right">Lorem Ipsum is simply dummy text of the printing and     typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</div>
<div style="clear:both"></div>

Answer 1

你可以通过CSS实现。您需要使用display:flex;并需要一个div来包裹您的left和right div /类。

.wrap {
    display:flex;
}
.left {
    width:30%;
    background:#000;
}
.right {
    width:70%;
    background:#eee;
}

<div class="wrap">
    <div class="left">sgdsfhdh</div>
    <div class="right">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</div>
    <div style="clear:both"></div>
</div>

此外，如果您仍然需要 JQuery 方式。

var oldheight=$("#right").height();  
  $('#right').bind('resize', function(){
          if($("#right").height()!=oldheight)
           {
            oldheight=$("#right").height();
           $('#left').css("height","30px");
            }
        });
