Navbar and THead Fixed-Top

时间：2019-03-19 15:16:13

标签： javascript jquery html twitter-bootstrap

I am creating a simple site that will show a list of computers along with some of their information. So far I've got everything functioning pretty much how I want except I can't get the thead to stay fixed to the navbar while scrolling. I'm still pretty new to all this, but I'll list some of the things I've tried below along with a simplified version of my web page.

  1. Putting a div around navbar/table through thead: Doesn't scroll
  2. Making the tbody scrollable and fixing the position of navbar/thead: ruined formatting
  3. Applying fixed position just to thead: Also ruins formatting

Any help is greatly appreciated!

JS

$(function() {
  $("#myTable").tablesorter();
});

    $(document).ready(function(){
      $("#myInput").on("keyup", function() {
        var value = $(this).val().toLowerCase();
        $("#myTableSearch tr").filter(function() {
          $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
        });
      });

我们可以使用here提供的答案进行以下修改：

net use X: "\\SERVERNAME\FOLDER" /user:"USER" "PASSWORD"
START X:\

现在移除.table-fixed { width: 100%; } .table-fixed thead th { position: sticky; position: -webkit-sticky; /*top: 0;*/ top:55px; /* the height of the fixed nav-bar */ z-index: 999; background-color: #000; color: #fff; } 中<br>之后的nav-bar。 

HTML

也许这会对您有所帮助。这是基于您自己的小提琴。

1st）通过简单的检查使thead固定，如下所示

$(window).scroll(function() {
if ($(this).scrollTop() >= 100) { 
    $('#myTable').addClass('fixed');  
} else {
            $('#myTable').removeClass('fixed');
    }
});

2nd）应用一些CSS 

#myTable.fixed thead { 
  position: fixed; background: #dddddd;
  left: 0; width: 100%;
}

我不确定哪种格式会被破坏，如果您正在谈论th，那么可以使用一些CSS设置样式

.table-area {
  position: relative;
  z-index: 0;
  margin-top: 60px;
}

table.rajresponsive-table {
  display: table;

  width: 100%;
 
  height: 100%;

table.rajresponsive-table thead {
  position: fixed;

  line-height: 3em;
