Add a new text element using jquery in bootstrap -

-

Hi, I am preparing a page in bootstrap, now I have to use some new dynamic features of jazzery. After clicking the user click the Options button, I must add a new text field (button ID = BTED). The new button should come in the next line after that button Here's the code. 
  & lt; Div class = "col-md-12 well sm" Role = "main" & gt; & Lt; Fieldset & gt; & Lt; Legend & gt; Please enter filter configuration here & lt; / Legend & gt; & Lt; Form & gt; & Lt; Div class = "row" & gt; & Lt; Div class = "col-xs-7" & gt; & Lt; Label = "server URL" & gt; Server URL: & lt; / Label & gt; & Lt; Input type = "server URL" class = "form-control" id = "server URL" placeholder = "Enter server URL" & gt; & Lt; / Div & gt; & Lt; Div class = "col-xs-7" & gt; & Lt; Label for = "pwd" & gt; Filter Name: & lt; / Label & gt; & Lt; Input type = "filter name" class = "form-control" id = "pwd" placeholder = "enter filter name" & gt; & Lt; / Div & gt; & Lt; Div class = "col-xs-7" & gt; & Lt; Label = "sel1" & gt; Filter Type: & lt; / Label & gt; & Lt; Select class = "form-control" id = "sel1" & gt; & Lt; Options & gt; Text & lt; / Options & gt; & Lt; Options & gt; List & lt; / Options & gt; & Lt; / Select & gt; & Lt; / Div & gt; & Lt; Div class = "col-xs-6" & gt; & Lt; Label = "filter option" & gt; Filter options: & lt; / Label & gt; & Lt; Span class = "inputWithButton" & gt; & Lt; Input type = "password" class = "form-control" id = "pwd" & gt; & Lt; Button class = "btn btn-info" id = "btAdd" & gt; Add option & lt; / Button & gt; & Lt; / Span & gt; & Lt; / Div & gt; & Lt; Div class = "col-xs-7" & gt; & Lt; Label = "filter label" & gt; Filter label: & lt; / Label & gt; & Lt; Button Type = "Button" class = "BTN BTN-Success" & gt; Add filter & lt; / Button & gt; & Lt; / Div & gt; & Lt; Div class = "form-group" & gt; & Lt; Div class = "col-sm-offset-3 col-sm-10" & gt; & Lt; Button type = "submit" class = "btn btn-success" & gt; Submit & lt; / Button & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Form & gt; & Lt; / Div & gt;    
 
 
 This is what you should do:  
  & Lt; Button class = "btn btn-info" id = "btAdd" onclick = "AddOption ()" & gt; Add option & lt; / Button & gt; & Lt; Div id = "optionsContainer" & gt; & Lt; / Div & gt; & Lt; Script & gt; Function AddOption () {var Container = $ ('# optionsContainer') ;; Container.epend ('& lt; input class = "form-control" id = "add-in input" placeholder = "enter option" & gt;'); } & Lt; / Script & gt;   
 OnClick calls a function that uses the JQuery addendum to add an element.

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...
