Ext.onReady(function(){

var store=new Ext.data.JsonStore({
url: 'ExtJson',

});

var columns = new Ext.grid.ColumnModel([
    {header: '学号', dataIndex: 'id'},
    {header: '性别', dataIndex: 'sex'},
      {header: '姓名', dataIndex: 'name'}

]);

    var grid = new Ext.grid.GridPanel({
    renderTo:"json",
    title: '学生信息列表',
    region: 'center',
    height:300,
    loadMask: true,
    store: store,
    cm: columns,
    sm: new Ext.grid.RowSelectionModel({singleSelect:true}),
    viewConfig: {
        forceFit: true        },
    bbar: new Ext.PagingToolbar({
        pageSize:3,
        store: store,
        displayInfo: true
    })
});
store.load();
  Ext.get("json").show();

});

那也是json格式，如果使用ext分页的话，你那json格式没法分页。只有改后台json格式
