Extjs和php交互的一个问题

treesky 2009-12-28 11:40:32



Ext.onReady(function(){

 var store = new Ext.data.Store({

    url:'data/income.php',

    reader: new Ext.data.JsonReader({

         idProperty: id,

         root: 'data',

         totalProperty: 'total',

         fields:[

            {name: 'stock_code', type: 'string'},

            {name: 'stock_name', type: 'string'},

            {name: 'stime', type: 'string'},

            {name: 'close', type: 'float'}

         ]

     }),

     remoteSort: true

    });

    var cm = new Ext.grid.ColumnModel([

        new Ext.grid.RowNumberer(),

        {header: "代码", width: 100, sortable: true, dataIndex: 'stock_code'},

        {header: "名称", width: 100, sortable: true, dataIndex: 'stock_name'},

        {header: "入选日期", width: 100, sortable: true, dataIndex: 'stime'},

        {header: "涨幅", width: 100, sortable: true, dataIndex: 'close'}

    ]);

    cm.defaultSortable = false;



    var rsm = new Ext.grid.RowSelectionModel({

        singleSelect: true

    });



    var grid = new Ext.grid.GridPanel({

    id:'grid',

        el:'stock_grid',

        width:document.body.clientWidth,

        height:572,

        store: store,

        colModel: cm,

        trackMouseOver:true,

    selModel: rsm,

    loadMask: ({

            msg: '数据加载中……'

        }),

        viewConfig: {

            forceFit:true,

            emptyText:'没有数据',

            enableRowBody:true

        }

    });

    grid.render();

    store.load();

});

income.php产生的json如下
{"total":20,"data":[{"id":"172","stock_code":"600859","stock_name":null,"close":"36.36","raises":"0.00","teacher":"admin123","stime":"2009-12-28","flag":"0","assessor":null,"hits":"1","state":"1","isauto":"1","ext1":"0","ext2":"0","ext3":"0","ext4":"0.00","ext5":"0.00"},{"id":"173","stock_code":"600241","stock_name":null,"close":"13.92","raises":"0.00","teacher":"admin123","stime":"2009-12-28","flag":"0","assessor":null,"hits":"1","state":"1","isauto":"0","ext1":"0","ext2":"0","ext3":"0","ext4":"0.00","ext5":"0.00"},{"id":"174","stock_code":"600243","stock_name":null,"close":"8.53","raises":"0.00","teacher":"admin123","stime":"2009-12-28","flag":"0","assessor":null,"hits":"1","state":"1","isauto":"0","ext1":"0","ext2":"0","ext3":"0","ext4":"0.00","ext5":"0.00"}
]}

这样试试：

 proxy: new Ext.data.HttpProxy({

           url:'data/income.php'

        }),

    reader: new Ext.data.JsonReader({

         idProperty: id,

         root: 'data',

         totalProperty: 'total',

         fields:[

            {name: 'stock_code', type: 'string'},

            {name: 'stock_name', type: 'string'},

            {name: 'stime', type: 'string'},

            {name: 'close', type: 'float'}

         ]

     })

如果不行，你把php传过来的json数据直接赋值在js中store调用。看是否运行正常。。详细操作可参见API中jsonreader的使用方法

fields:[
{name: 'stock_code', type: 'string'},
{name: 'stock_name', type: 'string'},
{name: 'stime', type: 'string'},
{name: 'close', type: 'float'}
]
只有四个，但是数据里超过四个，还能解析吗？
