如何使用Extjs4.1

Question

查询从服务器端数据我刚开始学ExtJS的，并希望实现服务器端query.I已经写了一些像这样的代码中的ExtJS Contriller我的MVC：

'SearchPanel button[action=select]': { 
       'click' : function() { 
        //console.log(Ext.getDom('s_name').value); 
        console.log(Ext.getCmp('s_studentid').getValue()); 
        var grid = Ext.ComponentQuery.query('studentList')[0]; 
        var store = grid.store; 

        store.filterBy(function(record) { 
         //return record.get('name') == '张新武' && record.get('id') == 8; 
         var s_studentid = Ext.getCmp('s_studentid').getValue(); 
         var s_name = Ext.getCmp('s_name').getValue(); 
         var s_unikey = Ext.getCmp('s_unikey').getValue(); 
         var s_type = Ext.getCmp('s_type').getValue(); 
         var s_sex = Ext.getCmp('s_sex').getValue(); 
         var s_college = Ext.getCmp('s_college').getValue(); 
         var s_major = Ext.getCmp('s_major').getValue(); 
         var s_ethnic = Ext.getCmp('s_ethnic').getValue(); 
         return (s_studentid == "" || record.get('id') == s_studentid) 
          &&(s_name == "" || record.get('name').indexOf(s_name)>=0) 
          &&(s_unikey == "" || record.get('name') == s_unikey) 
          &&(s_type == "" || record.get('type') == s_type) 
          &&(s_sex == "" || record.get('sex') == s_sex) 
          &&(s_college == "" || record.get('college') == s_college) 
          &&(s_major == "" || record.get('major') == s_major) 
          &&(s_ethnic == "" || record.get('ethnic') == s_ethnic); 
         console.log('invoke select'); 
        }); 
       } 
      } 

但我发现它从Extjs存储中查询数据，而不是从服务器端。如何更改我的代码以便它可以从服务器端查询数据。

您需要，以实现服务器端过滤

store.load({params: /* all this stuff */}) 

或类似..
