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.

table tr td{border:1px solid #ccc;text-align:center;cursor:pointer;}
.evenRow{background:#f0f0f0;}

/*

* 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。

</table>
<script>
$(function(){
  $("table").tableUI();
  })

</body>
