我们如何先选择自动隐藏值选项，然后选择所需的选项？

Question

在选择域之前：

div class="col-xs-12">
                    <label class=" required-field" for="Domain">Domain</label>
                    <select autocomplete="off" class="form-control select2-hidden-accessible valid" data-val="true" data-val-required="The 'Domain' field is required." id="Domain" name="Domain" tabindex="-1" aria-hidden="true" aria-describedby="Domain-error" aria-invalid="false">
                    <option value="">Select a domain...</option>
</select><span class="select2 select2-container select2-container--bootstrap select2-container--below select2-container--focus" dir="ltr" style="width: 100%;"><span class="selection"><span class="select2-selection select2-selection--single" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="0" aria-labelledby="select2-Domain-container"><span class="select2-selection__rendered" id="select2-Domain-container" title="Select a domain...">Select a domain...</span><span class="select2-selection__arrow" role="presentation"><b role="presentation"></b></span></span></span><span class="dropdown-wrapper" aria-hidden="true"></span></span>
                    <span class="field-validation-valid text-danger" data-valmsg-for="Domain" data-valmsg-replace="true"></span>
                </div>

域名选择后：

<select autocomplete="off" class="form-control select2-hidden-accessible" data-val="true" data-val-required="The 'Domain' field is required." id="Domain" name="Domain" tabindex="-1" aria-hidden="true"><option value="">Select a domain...</option>
<option value="ABC.abc.com">ABC.abc.com</option></select>
<span class="select2 select2-container select2-container--bootstrap select2-container--below select2-container--focus" dir="ltr" style="width: 100%;"><span class="selection"><span class="select2-selection select2-selection--single" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="0" aria-labelledby="select2-Domain-container"><span class="select2-selection__rendered" id="select2-Domain-container" title="ABC.abc.com">ABC.abc.com</span><span class="select2-selection__arrow" role="presentation"><b role="presentation"></b></span></span></span><span class="dropdown-wrapper" aria-hidden="true"></span></span>

当我们启动网站时，它将显示域名下拉列表和选项值为“选择域”。如果我选择“选择域”选项，将显示实际域名。（这意味着在我选择选择域选项之前，不会显示有效域名列表）

我是硒新手，所以我试着使用find_element_by_id和可见文本选项选择该选项。

我尝试了下面的python代码。但它不起作用。

select_element = Select(driver.find_element_by_id('Domain'));
print ([o.text for o in select_element.options])
select_element.select_by_visible_text('Select a domain...');
select_element1 = Select(driver.find_element_by_id('Select a domain...'));
select_element.select_by_value('XYZ.xyz.com')
wait = WebDriverWait(driver, 10 )
print('success')

我需要按以下顺序选择：

>

选择域按钮

接下来，我需要选择自动隐藏文本“选择域…”选项值。然后将显示域值。（注意：Utill Select a Domain…选项实际域名未列出）（另一个重要点有时即使选择Select Domain也会自动隐藏未立即列出的域列表可能需要一些等待时间）

加载域列表的等待期

如果任何共享Python完整代码的人被占用

在选择< code >选择域之前和之后，您的< code>select元素中的< code>class名称发生了变化...

以前：

class="form-control select2-hidden-accessible valid"

之后：

class="form-control select2-hidden-accessible"

似乎您需要 Web驱动程序等待，直到元素visibility_of_element_located。

导入此:

from selenium.webdriver.support import expected_conditions
from selenium.webdriver.support.ui import WebDriverWait

然后尝试：

select_element = Select(driver.find_element_by_id('Domain'));
print ([o.text for o in select_element.options])
select_element.select_by_visible_text('Select a domain...');
WebDriverWait(driver, 10).until(expected_conditions.visibility_of_element_located((By.XPATH, '//*[@id="Domain" and @class="form-control select2-hidden-accessible"]')))
slct = Select(driver.find_element_by_xpath('//*[@id="Domain" and @class="form-control select2-hidden-accessible"]'));

#update here
driver.find_element_by_xpath('//*[@id="Domain" and @class="form-control select2-hidden-accessible"]').click()
time.sleep(1)

slct.select_by_visible_text('XYZ.xyz.com')
#slct.select_by_value('XYZ.xyz.com')
print('success')
