python selenium hidden frame

Question

您好，我正在嘗試製作一個自動發佈在blogspot中的應用程序。前一陣子我可以想出Selenium。我的問題是點擊上傳圖片按鈕打開一個新的框架。我試圖切換一個框架，但每次頁面打開時框架名稱都會更改。唯一不變的是類名中的框架。頁面的iframe字段在頁面首次打開時似乎被禁用。

    resim_buton=wait.until(lambda driver:driver.find_element_by_css_selector('.tr-image').click()) 
    time.sleep(5) 


    iframe=driver.find_element_by_class_name('picker-frame') 

    driver.switch_to_frame(iframe)  

Answer 1

你可以得到iframe的name然後切換通過名字來IFRAME，看到以下內容：

if_name = driver.find_element_by_css_selector("iframe[class='picker-frame']").get_attribute("name") 
driver.switch_to_frame(if_name)
