jQuery数据显示插件整合

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：

//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");
