好久没有写东西了，当然不是没东西可写，只是没有时间写。今天抽出点时间来把我最近使用的一些 Javascript 特效的东西贴出来，供自己或者别人查询使用。最近我在做一个新的 B/S 系统，由于没有专门的美工人员和前端人员，所以这个工作我就担当起来。后端的代码是我的本职工作，没有话说。前端的东西就比较麻烦了。我最开始工作之初也做过美工，由于本人有绘画的功底，但是后来就把主要的经历放在了服务端代码了，因为大部分公司都会有前端人员来完成相应的工作。
当前的公司在技术方面没有什么积累，所以，所有的代码都要通过自己的编写来实现，前端也不例外。光前端的工作，本来打算2天搞完，后来发现超时2天。现在我要做一套UI的界面，通过后端数据生成前端的 Html Table 的样式，这部分工作已经完成。这个界面需要实现以下要求：隔行变色，可以进行全选、反选，选择的行变换背景色，并且鼠标经过行也要进行变色，同时，如果有选择的行，必须获取 CheckBox 的值，以后可以进行一些列操作。好久没有写前端代码了，也生了不少，这个过程很麻烦，现在终于过来了。为了防止以后还有这部分的需要，所以今天就把代码记录下来，便于以后查询使用。（这些对于高手来说，很简单，我不是高手针对前端，希望高手不要拍砖！）
一、先上一张图片，大家来看看效果！
二、有了以上图片，下面就直接贴代码了，先上 CSS 代码。
1 table{width:100%;border-collapse:collapse;margin:1em 0;} 2 table, td{font:100% Arial, Helvetica, sans-serif;font-size:13px;} 3 th,td{padding:.5em;border:1px solid #fff;} 4 th{background:#328aa4 url(tr_back.gif) repeat-x;color:#fff;font-size:14px;font-weight:bold;} 5 td{background:#e5f1f4;font-size:13px; cursor:pointer} 6 7 tr.even td{background:#e5f1f4;} 8 tr.odd td{background:#f8fbfc;} 9 10 tr.highlight td{background:#ecfbd4;} 11 tr.selected td{background:#bce774;color:#555;} 12 13 td input[type=checkbox] { display:inherit;text-align:center;outline:none } 14 td a.button{text-align:center;margin:0 5px; }
三、Html table 的代码
1 <table id="myDataTable" cellspacing="0" cellpadding="0"> 2 <thead> 3 <tr> 4 <th width="75"><center><label><input type="checkbox" id="cbMulController" name="cbMulController"></label></center></th> 5

五、总结了
好了，终于写完了，以后不怕了，这个东西，要想立刻能找到合适的代码不是那么容易，吃一堑长一智，我把这些经常用到的，就留下来，下次再找就容易了。不忘初心，继续努力。
