等待页面加载Selenium

Question

如何在数据绑定范围中选择一个值，以便我可以使用Selenium的wait命令等待它出现？

我希望它等到firstNum span出现。

<div class ="pagination-info">
     <span class="visiblelist">Showing</span>
     <span data-bind="number: firstNum">100</span>
     <span data-bind="number: lastNum">130</span>
</div>

代码段：

DRIVER = webdriver.Chrome(chrome_options=chrome_options)
DRIVER.get(url)
# wait should go here
data = DRIVER.page_source

附：这是一个动态网站，所以我将在url＆page = 1并转到url＆page = 2，我需要等待动态元素加载。

要使用数据绑定值等待<span>元素的可见性，您可以使用以下代码块：

DRIVER = webdriver.Chrome(chrome_options=chrome_options)
DRIVER.get(url)
WebDriverWait(DRIVER, 20).until(EC.visibility_of_element_located((By.XPATH, "//div[@class='pagination-info']//span[@data-bind='number: firstNum' and contains(.,'100')]"))) 
data = DRIVER.page_source
