javascript笔记:自己写一个jqgrid框架(二)
接着写我自己的Grid,做这件事情十分有成就感,只要有时间,我会继续努力下去的。
今天的版本里,我主要做了两件事情:
第一件:完全套用了jqGrid的css样式;当然不是简单的拿来就用,其实jqGrid的css样式使用的是jqueryUI,下面是jqueryUI的地址:
http://jqueryui.com/themeroller/
如下图:
点击“Gallery”标签,如图所示:
大家看到了,jqueryUI有不少皮肤可以用。
既然jqueryUI有很多皮肤可以用,我们现在又使用jqGrid默认的css样式,那么就可以让我们自己的Grid达到换肤的效果。
第二件:我为自己的Grid加入了一个分组数据的功能
首先还是给出项目的目录结构:
大家看到theme文件夹下有三个文件夹:
1.le-frog(jqueryUI绿色的样式)
2.smoothness(jqueryUI灰白色的样式,这是我喜欢的样式,也是我以后开发的默认样式)
3.redmond(这是jqGrid的默认样式)
文章结尾我会给出源代码下载链接,所以这里我只给出关键的代码:
xjqGrid-1.0.js:

换肤的关键代码就是:
<!--<link rel="stylesheet" type="text/css" media="screen" href="themes/redmond/jquery-ui-1.8.2.custom.css" />--> <link rel="stylesheet" type="text/css" media="screen" href="themes/smoothness/jquery-ui-1.8.21.custom.css" /> <!--<link rel="stylesheet" type="text/css" media="screen" href="themes/le-frog/jquery-ui-1.8.21.custom.css" />-->
jqGrid的样式不是太好用,我也添加了些自己的代码,修改的文件是ui.jqgrid.css,添加的代码如下:
/*xiajun add 2012-07-02*/ .ui-jqgrid-bdiv table tr.ui-widget-content td{border-right-color:inherit;border-right-style:solid;border-right-width:1px;text-align:left;border-bottom-color:inherit;border-bottom-style:solid;border-bottom-width:1px;font-weight:normal;height:22px} .ui-jqgrid-bdiv tr.jqgfirstrow td{padding:0px}
下面就是我的xjqGrid的效果,贴出图来秀秀:
