Extjs GridPanel description

1. In Ext, the table control must contain column definition information and specify the table data storage. Column information is defined by columns, while data storage is defined by store.

2. store is responsible for converting various raw data (JSON object arrays, etc.) into Ext. data. Record type objects.

It contains two parts: proxy and reader. Proxy specifies the way to obtain data. reader refers to how to parse this pile of data.

Simple store template code:

Var store = Ext. data. store ({proxy: {type: "ajax", url: "", reader: {type: "json", totalProperty: "count", root: "root", idProperty: "id" }}, fields: [{name: 'id', mapping: "id" },{ name: 'name', mapping: "name" },{ name: "desc", mapping: 'description'}]});
