Answer 1

参考var itemsPerPage = 2;   // set the number of items you want per pagevar store = Ext.create('Ext.data.Store', {
    id:'simpsonsStore',
    autoLoad: false,
    fields:['name', 'email', 'phone'],
    pageSize: itemsPerPage, // items per page
    proxy: {
        type: 'ajax',
        url: 'pagingstore.js',  // url that will load data with respect to start and limit params
        reader: {
            type: 'json',
            root: 'items',
            totalProperty: 'total'
        }
    }
});// specify segment of data you want to load using params
store.load({
    params:{
        start:0,    
        limit: itemsPerPage
    }
});Ext.create('Ext.grid.Panel', {
    title: 'Simpsons',
    store: store,
    columns: [
        {header: 'Name',  dataIndex: 'name'},
        {header: 'Email', dataIndex: 'email', flex:1},
        {header: 'Phone', dataIndex: 'phone'}
    ],
    width: 400,
    height: 125,
    dockedItems: [{
        xtype: 'pagingtoolbar',
        store: store,   // same store GridPanel is using
        dock: 'bottom',
        displayInfo: true
    }],
    renderTo: Ext.getBody()
}); 
用json数据只要root=articleList

Answer 2

分页的表格store需要在reader里指定json格式。
你贴出的json似乎末尾多了个","。
以下仅供参考：
reader: new Ext.data.JsonReader({
            root: 'articleList',
            totalProperty: 'totalCount',
            fields: [
                {name: 'replycount'},
                {name: 'lastpost'}
            ]
})JSON可以这样对应,增加totalCount，表示总条数。
{"totalCount":"1000","articleList":[{"articleId":1,"title":"1","author":"heshan","hits":"0","addDate":"2011-06-11 13:33:23"},{"articleId":2,"title":"2","author":"superman","hits":"0","addDate":"2011-06-11 13:35:18"},{"articleId":3,"title":"3","author":"superman","hits":"0","addDate":"2011-06-11 13:51:31"},{"articleId":4,"title":"4","author":"superman","hits":"0","addDate":"2011-06-11 13:55:54"},{"articleId":5,"title":"5","author":"superman","hits":"0","addDate":"2011-06-11 13:56:29"},{"articleId":6,"title":"拜拜拜拜吧","author":"superman","hits":"0","addDate":"2011-06-11 14:51:51"},{"articleId":7,"title":"333","author":"superman","hits":"0","addDate":"2011-06-11 15:00:56"}]}

实践证明：Json末尾的,不影响使用的,大家有没有看清楚我的问题？我是想直接读取JSON分页，不通过后台读取数据库的，JSON静态文件...
