Hi xiaoyunn,

You can use this before your create widget call. If a widget with the id is available it'll delete it before creating the widget. Understanding _WidgetBase - The Dojo Toolkit

if (dojo.byId(id)) { dojo.byId(id).destroyRecursive(false); }

Dear Mr Riyas Deen：

Thanks very much ，your answer general right，but maybe change the dojo to dijit like

if (dijit.byId(id)) { dijit.byId(id).destroyRecursive(); }
