Json encode ..

json string을 json object로 반드는 케이스

jsonData = Ext.util.JSON.decode("{'total_rows':4,'list':[{'trans_date_pos':'2008-4-4','domain':'test','warehouse':'K','qty':13},{'trans_date_pos':'2008-4-4','domain':'test','warehouse':'K','qty':13},{'trans_date_pos':'2008-4-4','domain':'test','warehouse':'K','qty':13},{'trans_date_pos':'2008-4-4','domain':'test','warehouse':'K','qty':13},{'trans_date_pos':'2008-4-5','domain':'test','warehouse':'K','qty':13},{'trans_date_pos':'2008-4-5','domain':'test','warehouse':'K','qty':13},{'trans_date_pos':'2008-4-5','domain':'test','warehouse':'K','qty':13}]}");
 

생성된 json object를 store에 저장함

// ext.data.groupingstore는 해당 자료를 grouping하기 위해 store대신 사용함
    store = new Ext.data.GroupingStore({       
        reader: new Ext.data.JsonReader({
            totalProperty: 'total_rows',
            root: "list",
            fields: ["trans_date_pos","domain","warehouse","qty"]
        }),
        data: jsonData,
        groupField:'trans_date_pos',
        autoLoad: true
    });
