selenium自学笔记---下拉框定位元素select

下拉框
1.先定位select 然后在定位option
city = driver.find_element_by_id("selCities_0")
city.find_element_by_xpath("//option[@value='50']").click()
或者 driver.find_element_by_id("selCities_0").find_element_by_xpath("//option[@value='50']").click()
2.通过xpath层级标签定位
driver.find_element_by_xpath("//select[@id='selCities_0']/option[3]")
