jQuery数据显示插件整合实现代码

显示表格数据会涉及到一些东西，如字段显示隐藏，数据状态，分页之类。

由于我们公司的产品涉及到很多的表格数据显示，而且每张表的字段数都很多，在工作过程中(几任同仁的努力)，整合出一套自认为较为轻巧的方案。如图：

其中涉及到的插件主要有：
jQuery.columnmanager.expand.js（扩展columnmanager）
jQuery.dropbox.js(自已写的)
jQuery.pager.expand.js(扩展pager) 
jQuery.cookie.js
 其中pager.expand.js,dropbox.js以及各插件间的整合在common.js里，代码如下：


代码如下:

//定义全局命名空间
var GLOBAL = {};
GLOBAL.Namespace = function(str) {
var arr = str.split("."), o = GLOBAL;
for (var i = (arr[0] == 'GLOBAL') ? 1 : 0; i < arr.length; i++) {
o[arr[i]] = o[arr[i]] || {};
o = o[arr[i]];
}
}
GLOBAL.Namespace("zyh");
