Question

我正在创建一个布局，我需要计算内容区域高度以保持页眉和页脚区域可见。但事实是，我已经使用切换包括show hide。所以当切换关闭时我的内容区域很好。但是如果切换开启，我无法计算内容区域的高度。请检查下面的代码，帮助我理清。感谢。

$(".toggleLink").click(function(){
	$(".wrapper").toggle();
});
var winHeight= $(window).height()-32;
var headHeight = $("#header").height();
var footHeight = $("#footer").height();
var toggleHeight = $("#showhide").height();
var contentHeight = winHeight - headHeight - footHeight - toggleHeight ;
$("#content").height(contentHeight);

body {
  padding: 0;
  margin: 0;
}

#header {
  width: 100%;
  height: 40px;
  background: #ccc;
}

.wrapper {
  display: none;
}

#content {
  border: 1px solid blue;
  padding: 15px;
  overflow: auto;
}

#footer {
  width: 100%;
  height: 50px;
  background: #CCC;
}

  <p>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.</p>
  <p>Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up
    one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum
    et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section
    1.10.32.
  </p>
  <p>There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum,
    you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary
    of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.</p>
  <p>The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions
    from the 1914 translation by H. Rackham.</p>

我不确定您的要求是这样的，请尝试此代码

 $(function () {
$(".toggleLink").click(function(){
            $(".wrapper").toggle();
   var winHeight= $(window).height()-32;
        var headHeight = $("#header").height();
        var footHeight = $("#footer").height();
        var toggleHeight = $("#showhide").height();
        var contentHeight = winHeight - headHeight - footHeight - toggleHeight; alert(contentHeight)
        $("#content").height(contentHeight);
        });
        var winHeight= $(window).height()-32;
        var headHeight = $("#header").height();
        var footHeight = $("#footer").height();
        var toggleHeight = $("#showhide").height();
        var contentHeight = winHeight - headHeight - footHeight - toggleHeight; alert(contentHeight)
        $("#content").height(contentHeight);
   });

在切换之前和之后计算jquery中的内容区域
