一、精确查找
<!DOCTYPE > <html> <head> <title></title> <meta charset="utf-8"> <script> window.onload = function() { var oTab = document.getElementById('tab1'); var oTbody = oTab.tBodies[0]; var oName = document.getElementById('name'); // 姓名 var oSearchBtn = document.getElementById('search'); // 搜索（按钮） oSearchBtn.onclick = function() { for(var i = 0; i < oTbody.rows.length; i++) { var name = oTbody.rows[i].cells[1].innerHTML; if(name == oName.value) { oTbody.rows[i].style.background = 'yellow'; } else { oTbody.rows[i].style.background = ''; } } } } </script> </head> <body> 姓名：<input type="text" name="name" id="name" value="张三" /> <input type="button" name="search" id="search" value="搜索" /> <div id="">搜索结果高亮显示 </div> <table id="tab1" width="300" border="1"> <thead> <td>ID</td> <td>姓名</td> <td>年龄</td> </thead> <tbody> <tr> <td>1</td> <td>Blue</td> <td>27</td> </tr> <tr> <td>2</td> <td>张三</td> <td>23</td> </tr> <tr> <td>3</td> <td>李四</td> <td>28</td> </tr> <tr> <td>4</td> <td>王五</td> <td>25</td> </tr> <tr> <td>5</td> <td>张伟</td> <td>24</td> </tr> </tbody> </table> </body> </html>

二、模糊查找
name.search(sName) != -1
oSearchBtn.onclick = function() { if(!oName.value) { alert("请输入关键字") } // 遍历整个表 for(var i = 0; i < oTbody.rows.length; i++) { var name = oTbody.rows[i].cells[1].innerHTML.toLowerCase(); var sName = oName.value.toLowerCase(); if(name.search(sName) != -1) { // 模糊查询 oTbody.rows[i].style.background = 'yellow'; } else { oTbody.rows[i].style.background = ''; } } }
