selenium常见问题：element is not attached to the page document，页面刷新后元素失效，需要重新定位元素

 测试中，常遇到此问题，特此写一个重新获取元素的函数，已供调用解决此方法

#找不到元素时，重新获取元素,eletype默认获取单个元素，若=1，则获取多个元素
#weblement有值，则传入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'没有找到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'没有找到element')
        elif eletype == 0:
            try:
                ele = CuoTiSelect.dr.find_element_by_css_selector(code)
                if ele.get_attribute('outerHTML') != '':
                    break

            except:

                pprint(u'没有找到element')



    return ele
