Question

我正在尝试从下拉列表中选择一个值，该值指示从网站显示的帖子数。

<form method="get" class="forumForm">
        <label for="dispItems">Show items:</label> 
        <select id="dispItems" class="dispItems">
            <option selected="selected">15</option>
            <option>30</option>
            <option>60</option>
            <option>90</option>
            <option>120</option>
            <option>150</option>
        </select>
</form>

我要更改此设置，以便选择最后一个选项。通过其他答案，我尝试了以下解决方案：

from selenium.webdriver.support.ui import Select

select = Select(driver.find_element_by_id("dispItems"))

# None of these two options work.
select.select_by_index(4)            # Option 1.
select.select_by_visible_text("150") # Option 2.

选项1和选项2都返回以下错误消息：

WebDriverException: Message:

如果我尝试：

select.select_by_visible_text("random")

我收到以下错误消息：

NoSuchElementException: Message: Could not locate element with visible text: random

编辑：KunduK提出的解决方案是

from selenium import webdriver
from selenium.webdriver.support.select import Select
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

element=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH    ,'//select[@id="dispItems"][@class="dispItems"]')))
time.sleep(1)
select=Select(element)
time.sleep(1)
select.select_by_visible_text('150')

Answer 1

尝试使用显式等待：

from selenium.webdriver.support.ui import Select
from selenium.webdriver.support import ui
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By


select = Select(ui.WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "dispItems"))))
select.select_by_index(4)

希望对您有帮助！

Answer 2

尝试以下选择最后一项 driver.find_element_by_xpath（“（// select [‘dispItems’] / option）[last（）]”）。click（）

Answer 3

尝试WebDriverWait，应该可以。

from selenium import webdriver
from selenium.webdriver.support.select import Select
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

element=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,'//select[@id="dispItems"][@class="dispItems"]')))
select=Select(element)
select.select_by_visible_text('150')

OR

from selenium import webdriver
from selenium.webdriver.support.select import Select
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys

element=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,'//select[@id="dispItems"][@class="dispItems"]')))
element.click()
element.send_keys(Keys.END)
element.send_keys(Keys.ENTER)

已编辑

：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
import time

element=WebDriverWait(driver,20).until(EC.element_to_be_clickable((By.XPATH,'//select[@id="dispItems"][@class="dispItems"]')))
element.click()
time.sleep(2)
element.send_keys(Keys.END)
time.sleep(2)
element.send_keys(Keys.ENTER)

如何通过硒从下拉列表中选择？
