controller层：
1 StdDayWordQuery:function(btn,event){ 2 var form=Ext.getCmp('queryFormSDW'); 3 paramsForDayWord=Ext.encode(form.getForm().getValues()); 4 Ext.Ajax.request({ 5 url:'getDailyWordNum.action', 6 headers: { 7 'Content-Type': 'application/json' 8 }, 9 params :paramsForDayWord, 10 async:false, 11 success:function(response) { 12 var results=Ext.decode(response.responseText); 13 if(results.success){ 14 var rows = results.rows; 15 var header = results.header; 16 var cols = new Array(); 17 cols.push(new Ext.grid.RowNumberer({ 18 xtype:'rownumberer', 19 text:'序号', 20 flex:1, 21 align:'center' 22 })); 23 for(var x in header){ 24 cols.push(new Ext.grid.column.Column({ 25 text: header[x], 26 dataIndex : header[x], 27 flex:1, 28 align:'center' 29 })); 30 } 31 var store = new Ext.data.Store({ 32 fields: header, 33 data: rows 34 }); 35 var grid = Ext.getCmp('StudentDayWordGrid'); 36 grid.reconfigure(store,cols); 37 Ext.getCmp('StudentDayWordGrid').show(); 38 } 39 else{ 40 Ext.Msg.alert("错误", results.msg); 41 paramsForDayWord=""; 42 Ext.getCmp('StudentDayWordGrid').hide(); 43 } 44 } 45 }); 46 },
view层：
