The example in this article describes how the jQuery plug-in realizes the color change of alternate rows in the table and the highlight effect when the mouse slides over it. Share it with everyone for your reference, the details are as follows:

This plug-in is designed to change the color of alternate rows in the table, and when the mouse moves over a certain row of the table, the row can be highlighted. The overall code is as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>表格隔行变色且鼠标滑过高亮显示</title>
<style>
table{border-collapse:collapse;border:none;width:20%;}
table tr td{border:1px solid #ccc;text-align:center;cursor:pointer;}
.evenRow{background:#f0f0f0;}
.oddRow{background:#ff0;}
.activeRow{background:#f00;color:#fff;}
</style>
<script type="text/javascript" src="jquery-1.7.1.js"></script>
</head>
<body>
<script>
/*
* tableUI 0.1
* 使用tableUI可以方便地将表格提示使用体验。先提供的功能有奇偶行颜色交替，鼠标移上高亮显示
* Dependence jquery-1.7.1.js
*/ 
;(function($){
  $.fn.tableUI = function(options){ //经常用options表示有许多个参数 
  //各种属性、参数  创建一些默认值，拓展任何被提供的选项
  var defaults = {
    evenRowClass:"evenRow",
    oddRowClass:"oddRow",
    activeRowClass:"activeRow" 
    };
  var obj = $.extend(defaults,options);
  this.each(function(){ //this关键字代表了这个插件将要执行的jQuery对象  此处没有必要将this包在$号中如$(this)，因为this已经是一个jQuery对象。  $(this)等同于 $($('#element'));
    //插件实现代码
    var thisTable = $(this); //获取当前对象  此时this关键字代表一个DOM元素  我们可以alert打印出此时的this代表的是object HTMLTableElement
    //添加奇偶行颜色
    $(thisTable).find("tr:even").addClass(obj.evenRowClass);
    $(thisTable).find("tr:odd").addClass(obj.oddRowClass);
    //添加活动行颜色
    $(thisTable).find("tr").mouseover(function(){
      $(this).addClass(obj.activeRowClass);
      });
    $(thisTable).find("tr").mouseout(function(){
      $(this).removeClass(obj.activeRowClass);
      });
    });
  };
})(jQuery);
//在这个封闭程序中，我们可以无限制的使用$符号来表示jQuery函数。
</script>
<table cellpadding="0" cellspacing="0">
 <tr><td>1</td><td>2</td><td>3</td></tr>
 <tr><td>1</td><td>2</td><td>3</td></tr>
 <tr><td>1</td><td>2</td><td>3</td></tr>
 <tr><td>1</td><td>2</td><td>3</td></tr>
 <tr><td>1</td><td>2</td><td>3</td></tr>
</table>
<script>
$(function(){
  $("table").tableUI();
  })
</script>
</body>
</html>
