This time I will bring you the jQuery plug-in to realize the table color change on alternate rows and interact with the mouse. The jQuery plug-in realizes the table color change on alternate rows and interacts with the mouse. What are the precautions? The following is a practical case, let’s take a look.

<!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>
