Python Selenium 按钮不会点击

Question

我正在尝试单击此“开始”按钮，但它没有工作。

这是 HTML：

<a name="DERIVED_SSS_SCL_SSS_GO_1" id="DERIVED_SSS_SCL_SSS_GO_1" role="button" onclick="javascript:cancelBubble(event);" href="javascript:submitAction_win1(document.win1,'DERIVED_SSS_SCL_SSS_GO_1');"><img src="https://sims-prd.sfu.ca/cs/csprd/cache/PT_NAV_GO_1.gif" name="DERIVED_SSS_SCL_SSS_GO_1$IMG" alt="Go" title="Go" border="0"></a>

我尝试了以下方法：

driver.find_element_by_xpath('//*[@id="DERIVED_SSS_SCL_SSS_GO_1"]').click()
driver.find_element_by_xpath("//a[contains(@href,'win1')]").click()
driver.find_element_by_id('DERIVED_SSS_SCL_SSS_GO_1').click()

感谢任何帮助。 谢谢。

编辑：包含更多 HTML，希望能够缩小我的问题范围。 我一定错过了这里的一些东西。

Answer 1

试试这个代码，看看它是否有效-

 element = driver.find_element_by_id("DERIVED_SSS_SCL_SSS_GO_1")
 driver.execute_script("arguments[0].click();", element)

更新

element = driver.find_element_by_xpath('//*[@id="DERIVED_SSS_SCL_SSS_GO_1"]/img')
driver.execute_script("arguments[0].click();", element)

Answer 2

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

selector = "//a[@id='DERIVED_SSS_SCL_SSS_GO_1']"

先试试这个：

element = WebDriverWait(driver, 5).until(
    EC.visibility_of_element_located((By.XPATH, selector))
)
element.click()

如果它不起作用，给这个机会：

element = WebDriverWait(driver, 5).until(
    EC.element_to_be_clickable((By.XPATH, selector))
)
element.click()
