HTML: 

  & lt; Div class = "navbar navbar-default navbar-fixed-top" role = "navigation" & gt; & Lt; Div class = "container" & gt; & Lt; Div & gt; & Lt; Ul class = "nav navbar-nav" & gt; & Lt; Li class = "dropdown" & gt; & Lt; A href = "#" class = "dropdown-toggle" data-toggle = "dropdown" & gt; Settings & lt; Span class = "caret" & gt; & Lt; / Span & gt; & Lt; / A & gt; & Lt; Ul class = "dropdown-menu" role = "menu" & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Edit & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Remove & lt; / A & gt; & Lt; / Li & gt; & Lt; Li class = "dropdown" & gt; & Lt; A href = "#" class = "dropdown-toggle" data-toggle = "dropdown" & gt; Visible by friends & lt; Span class = "caret" & gt; & Lt; / Span & gt; & Lt; / A & gt; & Lt; Ul class = "dropdown-menu" role = "menu" & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Visible by friends & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Visible only to me & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Visible by anyone & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt;    
 
 
 You can try manually triggering the dropdown on internal modal. See  
 JS:  
  $ ('dropdown li'). Click (function (e) {e.stopPropagation ();}); $ ('. Dropdown-inner'). Click (function (e) {estop propagation (); $ (this). Toggle class ('open'). Trigger ('shown.bs.dropdown');});   
 HTML:  
  & lt; Div class = "navbar navbar-default navbar-fixed-top" role = "navigation" & gt; & Lt; Div class = "container" & gt; & Lt; Div & gt; & Lt; Ul class = "nav navbar-nav" & gt; & Lt; Li class = "dropdown" & gt; & Lt; A href = "#" class = "dropdown-toggle" data-toggle = "dropdown" & gt; Settings & lt; Span class = "caret" & gt; & Lt; / Span & gt; & Lt; / A & gt; & Lt; Ul class = "dropdown-menu" role = "menu" & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Edit & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Remove & lt; / A & gt; & Lt; / Li & gt; & Lt; Li class = "dropdown-internal" & gt; & Lt; A href = "#" class = "dropdown-toggle-inner" & gt; Visible by friends & lt; Span class = "caret" & gt; & Lt; / Span & gt; & Lt; / A & gt; & Lt; Ul class = "dropdown-menu" role = "menu" & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Visible by friends & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Visible only to me & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Visible by anyone & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Div & gt; & Lt; / Div & gt;

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...

-
"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...
