html - 具有固定页眉和页脚以及可滚动内容的模式对话框

Question

我正在尝试创建一个模态对话框，它具有固定的页眉和页脚，并且模态对话框内的内容(在本例中为用户列表)是可滚动的...

到目前为止，我最好的尝试给了我图像上的结果:

我假设在看到图像后我不必描述问题是什么......我还假设你会知道解决方案必须是什么样子......:)

但为了确保我无论如何都会写它......模态对话框需要有一个固定的标题(标题“编辑板”“板名称”和“板类型”所在的区域)和页脚( “保存”按钮所在的区域)必须是固定的/不可滚动的……唯一必须滚动的是用户列表……

代码:

HTML:

<div id="addBoardModal" class="modal modal-fixed-footer">
    <form class="Boards_new" autocomplete="off">
      <div class="modal-header">
        <h5>{{title}}</h5>
        <div class="input-field">
           <!--INPUT FORM-->
        <div class="BoadType">
           <!--RADIAL BUTTON THING--> 
      <div class="modal-content">
            <div class="shareMembers" style="margin-top:18px;">
                <div class="row">
                    <h5 class="left">Share</h5>
                      <!--LIST OF USERS !!!THIS HAS TO BE SCROLLABLE!!!-->
                </div>
            </div>
      <div class="modal-footer">
        <!--JSUT THIS SAVE BUTTON-->
      </div>

CSS:

.modal {
  @extend .z-depth-4;
  display: none;
  position: fixed;
  left: 0;
  right: 0;
  background-color: #fafafa;
  padding: 0;
  max-height: 70%;
  width: 55%;
  margin: auto;
  //overflow-y: auto;
  border-radius: 2px;
  will-change: top, opacity;

     @media #{$medium-and-down} {
       width: 80%; }

  h1,h2,h3,h4 {
    margin-top: 0; }

.modal-header{
  border-bottom: 1px solid rgba(0, 0, 0, 0.1); 
  width: 100%; 
  height: 15rem; 
  padding:24px;
}

.modal-header > .input-field{width:100%;}

.modal-content {
  padding: 24px;
  position: absolute; 
  width: 100%; 
  overflow-y: auto; 
  -webkit-overflow-scrolling: touch;
}

.modal-close {cursor: pointer;}

.modal-footer {
  border-radius: 0 0 2px 2px;
  border-top: 1px solid rgba(0, 0, 0, 0.1);
  background-color: #fafafa;
  padding: 4px 6px;
  height: 56px;
  width: 100%;

.btn, .btn-flat {
  float: right;
  margin: 6px 0;
}
}
}

因此，如果有人可以告诉我我的代码中哪里做错了，或者我是否应该做一些不同的事情，那会很好...

我使用这些示例来编写代码... Example no.1 & Example no.2

您可以使用 calc() 函数尝试 max-height，例如:

.modal-content {
  height: auto !important;
  max-height: calc(100vh - 340px) !important;
}

看看下面的代码片段(使用全屏):

$(document).ready(function(){
    // the "href" attribute of .modal-trigger must specify the modal ID that wants to be triggered
    $('.modal-trigger').leanModal();
  });

.modal {
  overflow: hidden;
}

.modal-header {
  padding: 15px;
  border-bottom: 1px solid rgba(0, 0, 0, 0.1);
}

.modal-header h4 {
  margin: 0;
}

.modal-content {
  height: auto !important;
  max-height: calc(100vh - 340px) !important;
}

.content-row {
  display: flex;
  align-items: center;
  padding: 10px;
  border-bottom: 1px solid #ddd;
}

.content-row:last-child {
  border-bottom: none;
}

.icon {
  width: 40px;
  height: 40px;
  display: flex;
  align-items: center;
  justify-content: center;
  border-radius: 50%;
  background: #33b5e5;
  color: #fff;
}

.name {
  padding: 0 10px;
}

.role {
  padding: 0 10px;
  flex: 1;
  text-align: right;
}
