无法定位元素：{"method":"xpath","selector":"//input[@id='fieldname3_1']"}

Question

想用 python selenium 4 定位一个元素。我的代码：

x = s.find_element(By.XPATH,"//input[@id='fieldname3_1']")

https://thearbacademy.com/arbitrage-betting-calculator/

link 页面

HTML长得像

<input aria-label="" id="fieldname3_1" name="fieldname3_1" class="field number large valid" type="text" value="" aria-invalid="false">

我的错误：

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//input[@id='fieldname3_1']"}

Answer 1

检查 id 值，也使用 WebDriveWait 作为要加载的元素。

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

myElem = WebDriverWait(driver, 10).until(EC.visibility_of_all_elements_located((By.ID, 'fieldname2_1')))
#myElem.send_keys("123")

无法定位元素：{"method":"xpath","selector":"//input[@id='fieldname3_1']"}

Unable to locate element: {"method":"xpath","selector":"//input[@id='fieldname3_1']"}
