陳舊元素引用：元素沒有附加到頁面文檔的下拉列表 - python

我已經寫了一個ASP.net網站的硒鉻驅動程序腳本，並得到了stale element reference: element is not attached to the page document錯誤，同時運行它。陳舊元素引用：元素沒有附加到頁面文檔的下拉列表 - python

腳本假設從下拉列表中單擊一個項目。總共有4個下拉列表，當頁面加載第一個下拉菜單時有這樣的工作方式，當我們點擊第一個下拉菜單的第二個選項後，頁面加載數據到第二個下拉菜單和其他程序的相同過程之後，這個下面的代碼，我可以能夠選擇第二，第三，第四....首次下降的選項下來，然後得到錯誤，而選擇第二滴的第二個選項下

這裏是代碼

更改您的c一旦被改變頌歌從

makeOptions = make.find_elements_by_tag_name("option") 
print makeOptions 
for option in makeOptions: 
    optVal = option.get_attribute("value") 
    if optVal == '0': 
     continue 
    else: 
     print("Make is : %s" % optVal) 
     dataList['Make'] = optVal 
     ActionChains(driver).move_to_element(option).click(option) 
     option.click() 
     selectYear()

到元素集合在

options_count = len(make.find_elements_by_tag_name("option")) 

print makeOptions 
for i in range(0, options_count): 
    option = make.find_elements_by_tag_name("option")[i] 
    optVal = option.get_attribute("value") 
    if optVal == '0': 
     continue 
    else: 
     print("Make is : %s" % optVal) 
     dataList['Make'] = optVal 
     ActionChains(driver).move_to_element(option).click(option) 
     option.click() 
     selectYear()

元素將變得陳舊。所以當你遇到這樣的問題時你需要再次獲取元素
