用循环点击的方法这个按钮不好点

我看老师的视频里面就是这么点击的呀，而且她运行的时候也没报错呀

_AD · 2022 年8 月 19 日 02:41

Ui 自动化就是这样的不能保证每次执行都是一摸一样的。所以要用不同的方法

实例化显示等待的时候改一下，多添加一个忽略的异常。因为以前的版本是忽略所有异常，新的版本改成了只忽略NoSuchElementException，最好好好看一下源码，挺值得学习的:

        #应用循环点击的方法
        WebDriverWait(driver, 10, ignored_exceptions=ElementClickInterceptedException).until(muliti_click(
            (By.CSS_SELECTOR, ".dialog-footer .el-button.el-button--primary"),
            (By.XPATH, "//*[text()='创建成功']")
        ))
