生而知之者，上也。
The highest are those who are born wise.
學而知之者，次也。
Next are those who become wise by learning.
困而學之，又其次也。
After them come those who have to toil painfully in order to acquire learning.

Extjs GridPanel sorting triggers rowselect 解決排序觸發選擇紀錄

概念
記錄最後一筆紀錄的索引值，比對目前所選的紀錄值

surveyListGrid.getSelectionModel().on('rowselect',
    function(sm, rowIdx, row) {

    //記錄目前選擇的紀錄
     var selectedRow = surveyListGrid.store.getAt(rowIdx);
    //如果最後一筆與目前選擇相同，則不執行以下動作
     if(surveyListGrid.lastRow == selectedRow) {
          return;
     }
     //隨時記錄最後一筆紀錄的索引值
     surveyListGrid.lastRow = selectedRow;

});
