extjs - 每 10 分钟刷新一次 Web 服务

Question

我必须每 10 分钟刷新一次网络服务，我尝试使用 setInterval 它对我不起作用。这是我的代码，

onActivate:function() 
{
    setInterval(onActivate(),6000);     
    Ext.Ajax.request({
    method:'GET',
    contentType:'application/json; charset=utf-8',
    dataType:'json',
    url:'myurl',                                        
    //timeout:6000,
    disableCaching: false,
    interval:6000,
    reader: {
            type: 'json', 
            totalProperty: 'totalcount',
            rootProperty:'GetMobileOperatorListResult',
    },
    success:function(response,request)
    {
            var jsonarr = Ext.decode(response.responseText);
            var len=jsonarr.GetMobileOperatorListResult.length;
            console.log("length"+len);
            for(var i=0;i<len;i++)
            {  
                //Storing our values in Array
                var st =  {
                    'text':jsonarr.GetMobileOperatorListResult[i].Operator, 
                    'value':jsonarr.GetMobileOperatorListResult[i].OperatorValue,
                };  
                //Adding our array to LocalStore(localStorage)
                var localStore = Ext.getStore('MobileStore');
                localStore.add(st);                 
                localStore.sync();
                localStore.load();          
            }//for loop
            console.log("operator value\t"+st.value);
            localStore.getProxy().clear();
        },

查看 ExtJS 轮询提供程序

http://docs.sencha.com/extjs/4.2.1/#!/api/Ext.direct.PollingProvider

var poll = new Ext.direct.PollingProvider({
   type: 'polling',
   url: function () {
      Ext.Ajax.request({
         url: 'myurl',
         qualifier: 'Keep Alive',
         success: function (xhr) {
            //do your data processing here
         },
         failure: function () {
         }
      });
   },
   interval: 6000
});

Ext.Direct.addProvider(poll);
