But when i try to run the code i get this error: 但是当我尝试运行代码时,出现此错误:
no such element: Unable to locate element: {"method":"css
selector","selector":"btn-standard.call-to-action"}
How can I fix this? 我怎样才能解决这个问题?
Try this 尝试这个
btn = driver.find_element_by_css_selector(".btn-standard.call-to-action")
You are missing a dot at the beginning of css_selector so it looks for an element btn-standard
and not a class. 您在css_selector的开头缺少一个点,因此它查找的元素是
btn-standard
而不是类。 And there is no such element as btn-standard
而且没有
btn-standard
这样的元素
Also you can try element type with class like so: 您也可以尝试使用类的元素类型,如下所示:
btn = driver.find_element_by_css_selector("button.btn-standard")
Or any mix of class and element type 或类和元素类型的任何混合
For css selectors '.' 对于CSS选择器'。'。 is appended in the beginning only for class.
仅在课程开始时附加。 Can you try this:
你可以尝试一下:
btn = driver.find_element_by_css_selector("button.btn-standard")
您甚至可以使用xpath:
btn = driver.findElement(By.xpath("//button[contains(text(),'Login')]"))
