将从后台获取到的数据赋给Ext.data.JsonStore

我们从后台获取数据后，怎么赋给jsonStore呢？

 

1 从后台获取数据，自动load

var store = Ext.create('Ext.data.JsonStore', {

   storeId:'storeId',

 

        model: 'ImageModel',

        proxy: {

            type: 'ajax',

            url: '../../../quyTaskServlet.do',

            reader: {

                type: 'json',

                root: 'images'

            }

        }

    });

    store.load();

 

后台返回数据为：

[{"nexttime":"","lasttime":"","priority":5,"taskstat":"COMPLETE","taskname":"task4","flowname":"flow4","trigrule":"opermain","subsysid":"opermain"},{"nexttime":"","lasttime":"","priority":5,"taskstat":"COMPLETE","taskname":"task3","flowname":"flow3","trigrule":"opermain","subsysid":"opermain"},{"nexttime":"","lasttime":"","priority":5,"taskstat":"COMPLETE","taskname":"task2","flowname":"flow2","trigrule":"opermain","subsysid":"opermain"},]

 

2  从后台获取数据，手动load：

 

var quytask = Ext.create('Ext.Action', {

        text: '查询任务',

        iconCls: 'icon-add',

         handler: function(){

//store.reload();

Ext.Ajax.request({

url: '../../../quyTaskServlet.do',

params: {

 

subsysID:'opermain',

propathID:'serverId',

to:'scheduler'

 

},

 

success: function(response, opts) {

//alert(response.responseText);

var results = Ext.util.JSON.decode(response.responseText);

store.loadRecords(results);

},

failure: function(response, opts) {

console.log('server-side failure with status code ' + response.status);

}

});

}

    });
