尝试使用 Selenium 清理数据，但保存按钮不起作用

Question

我正在尝试使用机器学习算法的硒来保存展位地址，但保存按钮没有被单击。

在此处输入图像描述（软盘标志）

我尝试了所有类型的选择器、不同的方法、JavaScript 一切，但仍然不起作用。

这是我尝试的最后一个代码。

        self.vars = {}
        self.wait = WebDriverWait(self.driver, 10)  # Adjust timeout as needed

                # Optional: wait for a bit before proceeding to the next download
                time.sleep(1)

if __name__ == "__main__":
    dl = Download()
    dl.setup_method(None)
    try:
        dl.download_all()
    finally:
        dl.teardown_method(None)

我想以递归方式将它们下载为 Excel。

我希望下载 Excel 文件，以便单击保存图标。 请帮助卡住两天了。0

这段代码对我有用。如果不起作用，您能否在尝试下载数据之前确保页面上的所有内容均已加载且可见？

btn = self.driver.find_elements(By.XPATH, '//*[@title="Excel"]')
self.driver.execute_script ("arguments[0].click();", btn)
