固定高度，用于引导式预滚动DIV [英] Fixed height for bootstrap pre-scrollable DIV

问题描述

在我的应用程序中，我必须显示bootsatarp网格以用于数据库记录.由于记录数足够大而无需全页滚动即可查看，因此我使用了引导程序可预滚动div来包装我的表，它为我提供了滚动表的功能.但是，DIV大小始终是浏览器窗口的一半.我尝试了几乎所有堆栈溢出的帖子和建议，但它们根本不适合我.我还尝试通过Java脚本支持修复此问题，但它也失败了.

In my application I have to display bootsatarp grid for database records. Since the number of records count are large enough to view without full page scrolling I wrap my table with bootstrap pre-scrollable div and it gave me the functionality to scroll the table. However all the time DIV size is half of the browser windows. I tried almost every stack overflow posts and suggestions and simply they not work for me. I also tried to fix this with support of java script and it also failed.

这是我的HTML代码

<div class="col-md-9">
<div  class="pre-scrollable">
<table class="table table-bordered table-hover header-fixed"  id="sometable">
                    <thead>
                  <tr>
                    <th>EMP_No</th>
                    <th>Name</th>
                    <th>Designation</th>
                    <th>Department</th>
                    <th>Type</th>
                    <th>#Days</th>
                    <th>Start Date</th>
                    <th>End Date</th>
                    <th>Half day</th>
                    <th>Status</th>
                  </tr>
                </thead>
                <tbody>
                </tbody>
                <?php  //php code for print the table
                 ?>
</div>      
</div>

我在上面的表中填充了PHP代码的结果.我不知道如何将该DIV的高度设置为浏览器窗口的固定值或全值.以下是使用

I populate above table with the results of PHP code. I have not idea how to set this DIV's height to fixed value or full value of the browser windows.below are the CSS that are use

<style>
table {
    font-family: arial, sans-serif;
    border-collapse: collapse;
    width: 100%;
}
td, th {
    border: 1px solid #dddddd;
    text-align: center;
    padding: 1px;
}
thead th {
    text-align: center;
    background-color: #3498db;
}
tr:nth-child(even) {
    background-color: #dddddd;
}
</style>

这是结果网页

推荐答案

bootstrap css文件中为.pre-scrollable div设置了max-height属性.

There is a max-height property set for the .pre-scrollable div in the bootstrap css file.

.pre-scrollable {
    max-height: 340px;
    overflow-y: scroll;
}

这可能是问题的根源.
