getattribute

问题 I am creating a bot that would automate my work and copy particular values from a particular website. Everything works fine but the last lines of my code that says w.text produces an outcome which is text and I need a number. Each element that I need the value of looks like this after inspection: <span class="good">€25,217.65</span> How do I get the value as a number instead of as a text? I tried w.value or w.get_attribute('value) but it doesn't work. Here is my program (excluding downloads

问题 I'm re-implementing __getattribute__ for a class. I want to notice any incorrect (meaning failures are expected, of course) failures of providing attributes (because the __getattribute__ implementation turned out quite complex). For that I log a warning if my code was unable to find/provide the attribute just before raising an AttributeError . I'm aware: __getattribute__ implementations are encouraged to be as small as simple as possible. It is considered wrong for a __getattribute__

问题 I have a javascript function that tries to determine whether a div is visible and does various processes with that variable. I am successfully able to swap an elements visibility by changing it's display between none and block; but I cannot store this value... I have tried getting the elements display attribute value and finding if the the element ID is visible but neither has worked. When I try .getAttribute it always returns null; I am not sure why because I know that id is defined and it

问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: JavaScript setAttribute vs .attribute= javascript dom, how to handle "special properties" as versus attributes? Many times, in forums or places such as Usenet I have been told by some (when criticizing my code) that instead of saying, for example var link = a.href I should use var link = a.getAttribute('href'); instead. And use its complementary setAttribute() when wanting to assign. They say it is the correct

问题 I am trying to understand the difference between __getattr__ and __getattribute__ , however, I am failing at it. The answer to the Stack Overflow question Difference between __getattr__ vs __getattribute__ says: __getattribute__ is invoked before looking at the actual attributes on the object, and so can be tricky to implement correctly. You can end up in infinite recursions very easily. I have absolutely no idea what that means. Then it goes on to say: You almost certainly want __getattr__ .

问题 I have a problem with my class, when i call .getMake(); it always returns null, so I get the string "No Data". I know that Uri is not null because i get ther first Toast every time, with the uripath. I also know that the image has the tag "TAG_MAKE" (I checked it). It even didn't work with all the other tags. What should I change? public class ExifE { private Uri uri; private ExifInterface exifI; private Context context; public ExifE(Context con) { context = con; SharedPreferences prefs =
