getattribute

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 has a display attribute. Here is the code of the two different methods I have tried: var myvar = $("

The question refers to which one is preferable to be used in which use case, not about the technical background. In python, you can control the access of attributes via a property , a descriptor , or magic methods . Which one is most pythonic in which use case? All of them seem to have the same effect (see the examples below). I am looking for an answer like: Property : Should be used in case of … Descriptor : In the case of … it should be used instead of a property. Magic method : Only use if …. Example A use case would be an attribute that might not be able to be set in the __init__ method,

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 way to do it, that I am wrong, blah blah blah... I don’t normally pay any attention to those. And when I ask why nobody gives a real answer. Now I am curious about in

I need to verify the value of background color of div. Here's the HTML: <div id="outercontainer" align="left"> The information about background color is defined in file style.css like so: #outercontainer { background-color: #EAEAEA; margin-left: auto; margin-right: auto; opacity: 1; width: 1000px; z-index: 2; } I tried to get the value of bgcolor using selenium.getattribute command, but selenium returned me following error message : ERROR: Could not find element attribute: css=#oute rcontainer@background-color on session bc60eb07f15e4e63986634fb59bf58a1 as the result. This part of my code: try

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__ . Why? I read that if __getattribute__ fails, __getattr__ is called. So why are there two different

I'm working with Selenium in Python. I would like to get the .val() of a <select> element and check that it is what I expect. This is my code: def test_chart_renders_from_url(self): url = 'http://localhost:8000/analyse/' self.browser.get(url) org = driver.find_element_by_id('org') # Find the value of org? How can I do this? The Selenium docs seem to have plenty about selecting elements but nothing about attributes. Saifur You are probably looking for get_attribute() . An example is shown here as well def test_chart_renders_from_url(self): url = 'http://localhost:8000/analyse/' self.browser.get
