Question

我刚刚开始学习Extjs，想要实现服务器端查询。我在Exttrs MVC的Contriller中编写了一些这样的代码：

'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');
                    });
                }  
            }

但我发现它是从Extjs商店查询数据，而不是从服务器端查询数据。如何更改我的代码，它可以从服务器端查询数据。

您需要使用新的paramset重新加载才能实现服务器端过滤

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

或类似的..
