尝试 select 下拉选项时出现错误 "Message: stale element reference: element is not attached to the page document"

Question

select = Select(self.driver.find_element_by_xpath("/html/body/div[1]/section/div/div[1]/div/div[1]/div[2]/div/div[4]/form/div/select"))
options = len(self.driver.find_elements_by_xpath("/html/body/div[1]/section/div/div[1]/div/div[1]/div[2]/div/div[4]/form/div/select/option"))
m = 1
while m <= options:
    value = self.driver.find_element_by_xpath("/html/body/div[1]/section/div/div[1]/div/div[1]/div[2]/div/div[4]/form/div/select/option["+str(m)+"]").get_attribute("value")
    text = self.driver.find_element_by_xpath("/html/body/div[1]/section/div/div[1]/div/div[1]/div[2]/div/div[4]/form/div/select/option["+str(m)+"]").text
    select.select_by_value(value)

    m = m + 1

当运行代码出现以下错误时：

selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document (Session info: chrome=94.0.4606.71)

HTML代码如下：

<div class="select-field">
    <select name="group[14]" data-ajax-select-variants="true">
        <option selected="selected" value="211">
            1 Jahr                             
        </option>
        <option value="209">
            3 Jahre                             
        </option>
        <option value="348">
            5 Jahre                            
        </option>
    </select>
</div>

现在，它 select 的前两个选项没有任何问题，但是当它尝试 select 第三个选项时，它给了我上面显示的错误。

我试过了：

Select通过“select_by_visible_text”选择选项
通过 Select().options
for 循环 Select().options
Select通过“select_by_index”选择选项
在select取消选择新选项之前

表示对元素的引用现在是“陈旧的”--- 元素不再出现在页面的 DOM 上。这种期望的原因可能是您的 DOM 已更新或刷新。例如，执行 click() 等操作后，您的 DOM 可能会更新或刷新。此时当您尝试在 DOM 上查找元素时，您将遇到此错误。

您必须在更新或刷新中重新找到该元素 DOM

 try:  
        element1 = WebDriverWait(self.driver, 10).until(EC.visibility_of_element_located((By.xpath, "/html/body/div[1]/section/div/div[1]/div/div[1]/div[2]/div/div[4]/form/div/select/option["+str(m)+"]"))
        value = element1.get_attribute("value")
        element2 = WebDriverWait(self.driver, 10).until(EC.visibility_of_element_located((By.xpath, "/html/body/div[1]/section/div/div[1]/div/div[1]/div[2]/div/div[4]/form/div/select/option["+str(m)+"]"))
        text = element2.text
        select.select_by_value(value)  
 except StaleElementReferenceException:
        element1 = WebDriverWait(self.driver, 10).until(EC.visibility_of_element_located((By.xpath, "/html/body/div[1]/section/div/div[1]/div/div[1]/div[2]/div/div[4]/form/div/select/option["+str(m)+"]"))
        value = element1.get_attribute("value")
        element2 = WebDriverWait(self.driver, 10).until(EC.visibility_of_element_located((By.xpath, "/html/body/div[1]/section/div/div[1]/div/div[1]/div[2]/div/div[4]/form/div/select/option["+str(m)+"]"))
        text = element2.text

xPath是你用的不靠谱。如果 DOM 结构有任何变化，它将来可能会失败。
