測試中，常遇到此問題，特此寫一個重新獲取元素的函式，已供呼叫解決此方法

#找不到元素時，重新獲取元素,eletype預設獲取單個元素，若=1，則獲取多個元素
#weblement有值，則傳入webelement
def retying_get_element(self,code,eletype=0,webelement=None):
    count = 0
    ele = None
    while count <= 10:
        count += 1
        time.sleep(1)

        if eletype==1:
            if webelement == None:
                try:
                    ele = CuoTiSelect.dr.find_elements_by_css_selector(code)
                    for one in ele:
                        if one.get_attribute('outerHTML')!='':
                            break
                        else:
                            continue
                except:
                    pprint(u'沒有找到element')

            elif webelement is not None:
                try:
                    ele =webelement.find_elements_by_css_selector(code)
                    for one in ele:
                        if one.get_attribute('outerHTML') != '':
                            break
                        else:
                            continue
                except:
                    pprint(u'沒有找到element')
        elif eletype == 0:
            try:
                ele = CuoTiSelect.dr.find_element_by_css_selector(code)
                if ele.get_attribute('outerHTML') != '':
                    break

            except:

                pprint(u'沒有找到element')



    return ele
