javascript - Clickable colour boxes to change chat bubble colour -

-

I have a chat application where a user can submit a message and the message appears in the chat bubble with orange background I have created 5 colored div boxes that I want to link to the background color of the chat bubble. I hope that users can click on one of the colorful divas and the messages below will be displayed in the chat bubble along with that background. How can I do this?

See link for illustration:

Code:

HTML: 

  & lt; / Ul & gt; & Lt; Div & gt; & Lt; Input type = "text" id = "typetextbox" /> & Lt; Button type = "submit" id = "submit" & gt; & Lt; / Button & gt; & Lt; / Div & gt; & Lt; Div & gt; & Lt; Img src = "images / brown-block pages" id = "brown" /> gt; & Lt; / Div & gt; & Lt; Div & gt; & Lt; Img src = "images / blue-block pages" id = "blue" /> gt; & Lt; / Div & gt; & Lt; Div & gt; & Lt; Img src = "images / red-block" id = "red" /> gt; & Gt; / Div & gt; & Lt; Div & gt; & Lt; Img src = "images / green-block pages" id = "green" /> gt; & Gt; / Div & gt; & Lt; Div & gt; & Lt; Img src = "images / orange-block pages" id = "orange" /> & Lt; / Div & gt;   
  java  javasCRIPT:  
  $ ('# typetextbox'). Keypress (function (e) {if (e.key.code == 13) $ ('# submit'). Click ();}); Val (); If (message.replace (/ / g, '')) {var posts = makeNewPosition (); Var == ('  
 CSS:  
  li {height: auto, width: auto; Background: # E99D41; Status: Completed; Background opacity: 50%; Font-family: helvetica, non-serif, color: #fff; #blue {condition: full; Top: 88%; Left: 25%;}   
 Make # brown, # red, # green, and # organs similar to #blue.  
 I hope that all this makes sense, and I'm sure this is a very simple thing, but I really appreciate the help!

  var selected current = Color = undefined; $ ('.colorPicker & gt; div'). ('Click', function (e) {currentSelectedColor = $ (e.currentTarget) .attr ('class'); $ ('#tepetextbox') CSS ('background color', currentSelectedColor).}); $ ('# Submit') ('Click', function) {var msg = $ .trim ($ ('# typetextbox'). Val ()); if (msg == '') {return;} $ ('& lt; li / & AppendTo ('# messagebox') (AppendTo ("$ {": " );});   
  li {padding-bottom: 3px; List-style: none; } #message box & gt; Le & gt; Div {height: auto; Width: Auto; Font-family: helvetica, sans-serif; Display: Inline-Block} .colorPicker & gt; Div {width: 10px; Height: 10px; Display: inline-block} .red {background color: red; } .Green {background color: green; } .blue {background color: blue; }   
  & lt; Script src = "https://ajax.googleapis.com/ajax/libs/JQuery/1.1.1/jquery.min.js" & gt; & Lt; / Script & gt; & Lt; Ul id = 'message box' & gt; & Lt; / Ul & gt; & Lt; Div class = 'color picker' & gt; & Lt; Div squared = 'red' & gt; & Lt; / Div & gt; & Lt; Div square = 'green' & gt; & Lt; / Div & gt; & Lt; Div class = 'blue' & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Input type = "text" id = "typetextbox" /> & Lt; Button type = "button" id = "submit" & gt; Submit & lt; / Button & gt;

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...
