javascript - 使用 xpath 单击 aria-label 元素

Question

我无法使用 Xpath 和 Selenium 单击按钮，在这种情况下，aria-label 具有唯一的日期，这使得它可以完美地区分日历中的其他一些按钮。

This is the HTML code for the button that display the day 5 and the price for that day.

<button type="button" class="CalendarDay__button" aria-label="Choose sunday, february 4 2018 as your check-in date. It's available." tabindex="0"><div class="calendar-day"><div class="day">4</div><div class="flybondi font-p fare-price"><span>$728*</span></div></div></button>
<button type="button" class="CalendarDay__button" aria-label="Choose monday, february 5 2018 as your check-in date. It's available." tabindex="0"><div class="calendar-day"><div class="day">5</div><div class="flybondi font-p fare-price"><span>$728*</span></div></div></button>

#假设我想点击 2018 年 2 月 5 日，我试过了

dtd0_button = driver.find_element_by_xpath("//button[contains(@class, 'CalendarDay__button') and (@aria-label, 'Choose monday, February 5 2018 as your check-in date. It's available') ]")
dtd0_button.Click()

这种方法有什么问题，如果我可以点击网页日历中的任何日期，我会收到以下消息“WebElement”对象没有属性“Click”。

你的 xpath 有几个错误，导致它无效:

1. 首先，你必须在每个条件之前声明contains:

   "//button[contains(@attribute1, \"content1\") and contains(@attribute2, \"content2\")]"
   

2. 您的 xpath 中的 ' 未转义。尝试以下操作:

   "//button[contains(@class,\"CalendarDay__button\") and contains(@aria-label,\"Choose monday, february 5 2018 as your check-in date. It's available.\")]"
   

希望对您有所帮助。祝你好运!
