print('Execution Time: ', time.process_time() - start)
該腳本在步驟上有 2 個錯誤：
- 點擊“cari”按鈕
- 并下載檔案
，兩者都有相同的錯誤訊息：
TypeError: element_to_be_clickable() takes 1 positional argument but 2 were given
uj5u.com熱心網友回復：
代替
wait.until(EC.element_to_be_clickable(By.CSS_SELECTOR, "#searchButton")).click()
和
wait.until(EC.element_to_be_clickable(By.XPATH, "/html/body/main/div[2]/div/div/div[2]/div/dl/dd[5]/div[1]/a/text()")).click()
它應該是
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#searchButton"))).click()
和
wait.until(EC.element_to_be_clickable((By.XPATH, "/html/body/main/div[2]/div/div/div[2]/div/dl/dd[5]/div[1]/a/text()"))).click()
相應地。
請參閱此答案以獲取更多解釋。
此外，您必須改進定位器。長絕對 XPath 非常脆弱且不可靠。
此外，這里
inputElement2 = wait.until(EC.element_to_be_clickable((By.XPATH, '//*[@id="yearList"]/option[1]'))).click()
和這里
inputElement3 = wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#periodList > option:nth-child(3)"))).click()
您不需要宣告inputElement2和inputElement3變數，因為web_element.click()方法不回傳任何內容，因此這些變數正在獲取/保留NoneType物件。
