Question

我希望按值将下拉菜单中的一个选项存储为文本。我通过下一个Python脚本选择随机选项：

#Random select option by value
assignJob = Select(driver.find_element_by_name('job[job_title]'))
jobValue = str(randint(1, 6))
assignJob.select_by_value(jobValue)

HTML code：

<select name="job[job_title]" class="formSelect valid" id="job_job_title">
  <option value="" selected="selected">-- Select --</option>
  <option value="1">Customer Service</option>
  <option value="4">QA Engineer</option>
  <option value="3">QA Manager</option>
  <option value="2">SDET</option>
  <option value="5">Software Developer</option>
  <option value="6">Software Development Manager</option>
</select>

当我分配变量storedJob = driver.find_element_by_css_selector（“＃job_job_title option [value = jobValue]”）时出错.text：

Traceback (most recent call last):
  File "code.py", line 62, in <module>

代码：

jobValue = str(randint(1, 6))
assignJob.select_by_value(jobValue)
storedJob = driver.find_element_by_css_selector("#job_job_title option[value=jobValue]").text
print storedJob

Answer 1

您可以使用CSS选择器找到该选项并让selenium返回其文本。

driver.find_element_by_css_selector("#job_job_title option[value=2]").text

将2替换为您特定方案的变量jobValue。

修改

jobValue是一个变量（str），你不能直接在Python中传递一个变量。

jobValueSelector = "#job_job_title option[value='%s']" %jobValue storedJob = driver.find_element_by_css_selector(jobValueSelector).text print storedJob

Answer 2

下面的代码是Ruby。我认为Python和Ruby几乎是一样的。

select_list = driver.find_element(:id, 'job_job_title')
options = select_list.find_elements(:tag_name, 'option')
index = rand(1..options.count) # Get random number from index 1 to options.count
my_variable =  options[index]

让我尝试使用Python的技巧（未经测试）！：）

select_list = driver.find_element_by_id("job_job_title")
options = select_list.find_elements_by_tag_name("option")
index = randint(1, len(options)) 
variable = options[index]

的webdriver。蟒蛇。我希望按值将下拉菜单中的一个选项存储为文本，怎么做？
