Python Selenium 嘗試單擊按鈕不起作用

Question

我正在嘗試使用 CSS 選擇器單擊按鈕。 我嘗試使用帶有值、標題和 onclick 的輸入，但不起作用，這是html 代碼：

<div id="botaoMarcar"><input type="button" disabled class="botao"
value="Marcar todas" title="Marcar todas" onclick="javascript:marcarDesmarcarTodos(true);"
></div>

我的代碼：

driver = Chrome()
url = "https://www3.bcb.gov.br/sgspub/localizarseries/localizarSeries.do?method=prepararTelaLocalizarSeries"
driver.get(url)

try:
    WebDriverWait(driver, 3).until(EC.alert_is_present(),
                                   'Timed out waiting for PA creation ' + 'confirmation popup to appear.')

    alert = driver.switch_to.alert
    alert.accept()
except TimeoutException:
    print("No Alert")


driver.implicitly_wait(5)
driver.maximize_window()

# This part is for input table code that I want to access
id_code = driver.find_element(By.ID, 'txCodigo')
id_code.send_keys(24)
id_code.send_keys(Keys.ENTER)

# Part not working exactly
clic_code = driver.find_element(By.CSS_SELECTOR, 'input[value*="Marcar todas"]')
clic_code.click()

Answer 1

您的元素位於 iframe 中。

<iframe id="iCorpo" name="iCorpo" align="center" marginwidth="0" marginheight="0" src="localizarSeries.do?method=recuperarGruposPrincipais" frameborder="0" width="100%" scrolling="auto" height="280" style="height: 399.36px;"></iframe>

只需等待並在找到該元素之前切換到它。

WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"#iCorpo")))
