//=============================<br>
Menu表中<br>
MenuId 為菜單編號(hào),必須唯一。建此此菜單使用類似本DEMO中所使用具有一定規(guī)則的編號(hào),方便將來(lái)的權(quán)限管理使用<br>
ParentId 為當(dāng)前菜單的父菜單編號(hào),當(dāng)此字段值為0則該菜單為一級(jí)菜單<br><br>
本例遞歸函數(shù)加入levelCount參數(shù)來(lái)確定當(dāng)前遞歸的層數(shù),可使用此參數(shù)判斷當(dāng)前第幾級(jí),并且可控制當(dāng)前級(jí)別調(diào)用的樣式表<br>
