Selenium Python：从<a> tag

Question

On a particular webpage, I have the following tag :

<a id="AAA" class="BBB" data-json="{"link":"thelink","field1":1,"field2":5}">
Load more
</a>

I am using Selenium / Python. I want to click 5 times on this tag, where 5 is the value from "field2" in "data-json".

The XPATH is ".//*[@id='AAA']" (thanks to FireXPath) so I want to use 5 times the following command:

browser.findElement(By.XATH(".//*[@id='AAA']")).click();

Question is : how to extract this "5" from < a tag > / data-json / field2 ?

Answer 1

要获取属性的值，可以使用函数get_attribute link，在这种特殊情况下，我们必须将data-json解析为dict并获取数字。我的建议是：

import json    
json_dict = json.loads(browser.findElement(By.ID('AAA')).get_attribute('data-json'))
number_times = json_dict["field2"]

Answer 2

正如同行所提到的，使用 id 会好得多。

您可以使用get_attribute和json convertion：

>>> import json
>>> data = browser.find_element_by_id("AAA").get_attribute("data-json")
>>> json.loads(data)["field2"]
>>> 5
