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:【WEB前端开发】jQuery数据显示插件整合实现代码_jquery

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:

复制代码 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");
