jQuery data display plug-in integration implementation code_jquery

Displaying table data will involve some things, such as showing and hiding fields, data status, paging, etc.

Since our company's products involve a lot of table data display, and each table has a lot of fields, during the work process (with the efforts of several colleagues), we integrated a solution that we thought was relatively lightweight. As shown in the picture:

The plug-ins involved mainly include:
jQuery.columnmanager.expand.js (extend columnmanager)
jQuery.dropbox.js (self-written)
jQuery.pager.expand.js (extend pager)
jQuery.cookie.js
Among them, pager.expand.js, dropbox.js and the integration between various plug-ins are in common.js. The code is as follows:

Copy code The code is as follows:

//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");
