Select方法

使用WebElement类的send_keys(value)方法也可以选择下拉框(select标签)的值,但它只能使用选项的value值来定位:

self.driver.get("http://sahitest.com/demo/selectTest.htm")
ele = self.driver.find_element_by_id('s3Id')
print(ele.text) # 打印select所有选项值
ele.send_keys("o2val") # 选择value=o2val 的选项
print(ele.get_attribute("value")) # 打印所选择的value值

结果:

o1
o2
o3
    With spaces
    With nbsp
o2val

select类所有方法:

  1. select_by_index(index):通过选项index选择
  2. select_by_value(value):通过选项value值选择
  3. select_by_visible_text(text):过显示的文本选择
  4. deselect_by_index(index):取消选择,用于多选
  5. deselect_by_value(value):取消选择,用于多选
  6. deselect_by_visible_text(text):取消选择,用于多选
  7. deselect_all():全部取消,用于多选
  8. options:所有选项
  9. first_selected_option:第一个选择的选项(多选情况下)或者当前选择的选项(单选)
  10. all_selected_options:所有已经选择的选项

选择

select_by_index、select_by_value、select_by_visible_text三种方法选择

first_selected_option.text返回当前所选择的选项值

self.driver.get("http://sahitest.com/demo/selectTest.htm")
ele = self.driver.find_element_by_id('s3Id')
selected_element = Select(ele)  # 实例化Select
selected_element.select_by_index(1)
# for select in selected_element.all_selected_options:
#     print(select.text)
print(selected_element.first_selected_option.text) # 打印当前选择的选项值
sleep(1)
selected_element.select_by_value("o2val")
print(selected_element.first_selected_option.text)
sleep(1)
selected_element.select_by_visible_text("o3")
print(selected_element.first_selected_option.text)
sleep(1)

结果:

o1 
o2 
o3

取消选择

取消选择deselect不能用于下拉框选择,只能用于多选,即属性multiple="multiple"的select标签。

取消选择有deselect_by_indexdeselect_by_valuedeselect_by_visible_textdeselect_all四种方法

all_selected_options返回所有已选择的选项

self.driver.get("http://sahitest.com/demo/selectTest.htm")
## 多选
ele2 = self.driver.find_element_by_id('s4Id')
selected_element2 = Select(ele2)  # 实例化Select
selected_element2.select_by_index(1)
selected_element2.select_by_index(2)
selected_element2.select_by_index(3)
print("######")
for select in selected_element2.all_selected_options:
    print(select.text)

print("######")
selected_element2.deselect_by_index(1)
for select in selected_element2.all_selected_options:
    print(select.text)

print("######")
selected_element2.deselect_by_value("o2val")
for select in selected_element2.all_selected_options:
    print(select.text)

print("######")
selected_element2.deselect_by_visible_text("o3")
for select in selected_element2.all_selected_options:
    print(select.text)

结果:

######
