python+selenium元素定位03——自动化常见场景处理

      举例：

         value = driver.switch_to.alert

         value.alert()  #跳转到js弹窗    |    value.accept() 弹窗上的确认（点击确认） 

         value.dismiss() 弹窗上的取消（关闭弹窗/确认取消）  |    value.text() 弹窗上的内容

         driver.switch_to.alert.send_keys(‘我??傻瓜呆‘) #弹窗上输入内容，只对prompt有效
   driver.switch_to.alert.accept()

#1、下拉框通过元素定位识别
# driver.find_element(By.XPATH,‘//select[@id="Selector"]‘).click()
# 2、通过下拉框对象内置的方法去选择
select_el = driver.find_element(By.XPATH,‘//select[@id="Selector"]‘)
sel = Select(select_el)   #强制转换为下拉框
sel.select_by_visible_text(‘桃子‘)
sel.select_by_index(3)
time.sleep(2)
sel.select_by_value("orange")
time.sleep(3)
driver.quit()
