jquery - Detect the height auto using javascript -

-

I have a div with a certain height (ex: 500px). This div contains some HTML block elements. What I would like to achieve is using javascript to find out at which height my devices will be, if I set the height of that fixed height automatically.

: 500px; "& Gt; & lt; p & gt; My Paragraphs & lt; / p & gt; & lt; h1 & gt; My Title & lt; / h1 & gt; & lt; / div & gt;

In the second order of words, I want to get the height of the div without considering the white space from the bottom.

Is there any way I can do that?

How can you calculate and add height of children? Something like this: 

 < Code> & lt; div id = "# someId" style = "height: 500px;" & gt; & lt; p & gt; my paragraph & lt; / p & gt; & lt; h1 & gt; my title & Lt; / h1 &   
 then in jQuery  
  var height = $ ('# someId & gt; p'). () + $ ('# SomeId & gt; h1'). Height ();   
  Edit:  Or if you want to do something normal: / P> 
  var height = 0; $ ("#someId"). Child (). (Function () {height = height + $ (this) .hit ();})

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
