如何使用 Selenium - Python 选择下拉菜单选项值

Question

我需要从下面的下拉菜单中选择一个元素。

<select class="chosen" id="fruitType" name="fruitType">
    <option value="">Select</option>
    <option value="1">jumbo fruit 1</option>
    <option value="2">jumbo fruit 2</option>
    <option value="3">jumbo fruit 3</option>
    <option value="4">jumbo fruit 4</option>
    <option value="5">jumbo fruit 5</option>
    <option value="8">jumbo fruit 6</option>
</select>

我已尝试使用此代码，

driver = webdriver.Firefox()
driver.find_element_by_xpath("//select[@name='fruitType']/option[text()='jumbo fruit 4']").click()

但它返回给我错误。 我怎样才能做到这一点。

Answer 1

来自official documentation：

from selenium.webdriver.support.ui import Select

select = Select(driver.find_element_by_id('fruitType'))
# Now we have many different alternatives to select an option.
select.select_by_index(4)
select.select_by_visible_text("jumbo fruit 4")
select.select_by_value('4') #Pass value as string

Answer 2

您可以像这样遍历所有选项：

element = driver.find_element_by_xpath("//select[@name='fruitType']")
all_options = element.find_elements_by_tag_name("option")
for option in all_options:
    print("Value is: %s" % option.get_attribute("value"))
    option.click()

Answer 3

您好，只需使用一行代码就可以了

// please note the if in case you have to select a value form a drop down with tag 
// name Select then use below code it will work like charm
driver.find_element_by_id("fruitType").send_keys("jumbo fruit 4");

希望对你有帮助
