The example in this article describes the method of using JavaScript to highlight selected rows in a table with a specified color. Share it with everyone for your reference. The specific implementation method is as follows: 

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>table选中的行以指定颜色高亮显示</title>
<script type="text/javascript">
function IniEvent() {
  var tbl = document.getElementById("tblMain");
  var trs = tbl.getElementsByTagName("tr");
  for (var i = 0; i < trs.length; i++) {
 trs[i].onclick = TrOnClick;
  }
}
function TrOnClick() {
  var tbl = document.getElementById("tblMain");
  var trs = tbl.getElementsByTagName("tr");
  for (var i = 0; i < trs.length; i++) {
 if (trs[i] == this) { //判断是不是当前选择的行
   trs[i].style.background = "yellow";
 }
 else {
   trs[i].style.background = "white";
 }
  }
}
</script>
</head>
<body onload="IniEvent()">
<table id="tblMain" border="1">
<tr>
  <td>1</td>
  <td>三星</td>
  <td>AA</td>
</tr>
<tr>
  <td>2</td>
  <td>Norkia</td>
  <td>BB</td>
</tr>
<tr>
  <td>3</td>
  <td>苹果</td>
  <td>CC</td>
</tr>
<tr>
  <td>4</td>
  <td>联想</td>
  <td>DD</td>
</tr>
</table>
</body>
</html>

I hope this article will be helpful to everyone’s JavaScript programming design.
