Question

我从Selenium Python的下拉字段中选择一个值。我收到了错误：

AttributeError: 'WebElement' object has no attribute 'select_by_visible_text'

我选择下拉列表的方法是：

def select_dataset_from_dataset_dropdown(self):
    dataset_drop_down_element = WebDriverWait(self.driver, 20).until(EC.element_to_be_clickable((By.ID, 'search_variables_lb_datasets')))
    dataset_drop_down_element.select_by_visible_text(str("Query (Query)"))

HTML是：

    <select id="search_variables_lb_datasets" class="gwt-ListBox marginbelow" style="display: inline;">
<option value="-">-</option>
<option value="CRM">CRM</option>
<option value="ESCR">ESCR</option>
<option value="ORCHARD">ORCHARD</option>
<option value="Edit_test">Edit_test</option>
<option value="Query (Query)">Query (Query)</option>
</select>

我想选择值＆＃34;查询（查询）＆＃34;

我可以选择这个值吗？

错误跟踪是：

Traceback (most recent call last):
  File "C:\Webdriver\ClearCore Regression Test\ClearCore - Regression Test\TestCases\StructuredSearch_TestCase.py", line 54, in test_00001_create_search_query_dataset_for_search_and_check_search_variables_dm_query_variables_are_displayed

    dataset_drop_down_element.select_by_visible_text(str("Query (Query)"))
AttributeError: 'WebElement' object has no attribute 'select_by_visible_text'

select_by_visible_text()方法在Select类上可用，实例化它：

from selenium.webdriver.support.select import Select

dataset_drop_down_element = WebDriverWait(self.driver, 20).until(EC.element_to_be_clickable((By.ID, 'search_variables_lb_datasets')))
dataset_drop_down_element = Select(dataset_drop_down_element)

Selenium Python AttributeError：＆＃39; WebElement＆＃39;对象没有属性＆＃39; select_by_visible_text＆＃39;
