selenium報異常：it is not in the current frame context, or the document has been refreshed

問題描述：下拉框選擇了某個值去查詢，查詢後將下拉框復原爲默認值，出現了異常提醒。

1、代碼及報錯

代碼

    def type_query(self,target_loc,row):
        try:
            ele_sel = Select(self.find_element(*target_loc))
            ele_sel.select_by_index(row)
            sleep(0.2)
            self.find_element(*self.BaImp_loc).click()
            sleep(2)
            ele_sel.select_by_index(0)
        except BaseException as msg:
            print(msg)

報錯信息

Message: The element reference of <select id="state" name="state"> is stale; either the element is no longer attached to the DOM, it is not in the current frame context, or the document has been refreshed

2、解決方法

點擊查詢後，頁面被刷新，ele_sel已失效，需要重新獲取。

    def type_query(self,target_loc,row):
        try:
            ele_sel = Select(self.find_element(*target_loc))
            ele_sel.select_by_index(row)
            sleep(0.2)
            self.find_element(*self.BaImp_loc).click()
            sleep(2)
            ele_sel0 = Select(self.find_element(*target_loc))#重新獲取
            ele_sel0.select_by_index(0)
        except BaseException as msg:
            print(msg)
