when there is a lot of data in the table and we cannot search page by page, we can search through a search box.

for this search box, for a better experience, we can use the keyup event to start filtering when the user inputs, instead of clicking the search button after filling in the form.
rendering:

implementation code:

<html>
<head>
 <meta charset="utf-8" />
 <script src="jquery-1.3.2.min.js"></script>
 <link href="css/style.css" rel="stylesheet" type="text/css" />
 <script>
  $(function () {
   $("tr.parent").click(function () {
    $(this)
    .siblings('.child_'+this.id).toggle();
    
   });
   $("tr.parent").addClass("selected");
   $("#searchbox").keyup(function () {
    $("table tbody tr").hide()
    .filter(":contains('"+($(this).val())+"')").show();//filter和contains共同来实现了这个功能。
   }).keyup();
  });
 </script>
 <title></title>
</head>
<body>
 <label>筛选</label>
 <input type="text" id="searchbox"/>
 <table>
  <thead>
   <tr><td>姓名</td><td>性别</td><td>暂住地</td></tr>
  </thead>
  <tbody>
   <tr class="parent" id="row_01"><td>前台设计组</td></tr>
   <tr class="child_row_01"><td>张山</td><td>男</td><td>湖北</td></tr>
   <tr class="child_row_01"><td>李山</td><td>男</td><td>湖北</td></tr>
   <tr class="child_row_01"><td>张山</td><td>男</td><td>湖北</td></tr>
   <tr class="child_row_01"><td>张山</td><td>男</td><td>湖北</td></tr>
   <tr class="parent" id="row_02"><td>前台设计组</td></tr>
   <tr class="child_row_02"><td>张山</td><td>男</td><td>湖北</td></tr>
   <tr class="child_row_02"><td>张山</td><td>男</td><td>湖北</td></tr>
   <tr class="child_row_02"><td>张山</td><td>男</td><td>湖北</td></tr>
   <tr class="child_row_02"><td>张山</td><td>男</td><td>湖北</td></tr>
   <tr class="parent" id="row_03"><td>前台设计组</td></tr>
   <tr class="child_row_03"><td>张山</td><td>男</td><td>湖北</td></tr>
   <tr class="child_row_03"><td>张山</td><td>男</td><td>湖北</td></tr>
   <tr class="child_row_03"><td>张山</td><td>男</td><td>湖北</td></tr>
