我的網頁結果帶有如下 html 標簽，我需要回圈每個值并從表中獲取結果
<div class = "divList">
<select class="form selectList">
<option value="3710">Thu, 04 Nov 2021</option>
<option value="3709">Mon, 01 Nov 2021</option>
<option value="3708">Mon, 01 Nov 2021</option>
....
</select>
</div>dropdownlist = driver.find_element_by_class_name('divList')
valueslist = (dropdownlist.text).splitlines()
print(valueslist)
sel = Select(driver.find_element_by_xpath("//select[@class='form selectList']"))
for value in valueslist:
print(value)
sel.select_by_visible_text(value)
print('Processing - ', value)
time.sleep(3)
在 2 次迭代后更改值時出現以下錯誤
Thu, 04 Nov 2021
Processing - Thu, 04 Nov 2021
Mon, 01 Nov 2021
Processing - Mon, 01 Nov 2021

selenium.common.exceptions.StaleElementReferenceException：訊息：過時的元素參考：元素未附加到頁面檔案
uj5u.com熱心網友回復：
嘗試這個：
dropdownlist = driver.find_element_by_class_name('divList')
valueslist = (dropdownlist.text).splitlines()
print(valueslist)
sel = Select(driver.find_element_by_xpath("//select[@class='form selectList']"))
for value in valueslist:
sel = Select(driver.find_element_by_xpath("//select[@class='form selectList']"))
sel.select_by_visible_text(value)
print('Processing - ', value)
time.sleep(3)
如果您愿意，您可以通過以下方式簡化：
sel = Select(driver.find_element_by_xpath("//select[@class='form selectList']"))
nbritems = len(sel.options)
for i in range(0, nbritems):
sel = Select(driver.find_element_by_xpath("//select[@class='form selectList']"))
txt = sel.options[i].text
sel.select_by_visible_text(txt)
print('Processing - ', txt)
time.sleep(3)
selenium.common.exceptions.StaleElementReferenceException：訊息：過時的元素參考：元素未附加到頁面檔案
字面意思是about，參考的元素已經過期，不再附加到當前頁面。通常，這是因為頁面被重繪 或跳過了，解決方法是，重用 findElement 或 findElements 方法來定位元素。
