javascript - How to make an image change into others on click? -

-

I'm trying to create a minimum clickable "slideshow". So far, I have only changed the image change to another. But I want to add it to other images. I tried to add other ifs and elses on javascript but it does not work (i am a noob ...) how can i do this? I want to click Jat and change the picture. This is my code so far: 

  & lt; Div & gt; & Lt; Img alt = "" src = "1.jpg" id = "imgClick and Replace" onclick = "changeImage ()" /> & Lt; / Div & gt; & Lt; Script language = "javascript" & gt; Changemage function () {if (Dokyumentkgetelementbyid ( "Imgklikkndchange"). Src = "Lkjpg") {Dokyumentkgetelementbyid ( "Imgklikkndchange"). Src = "2.jpg"; Document.getElementById ("imgClickAndChange") Src = "3.jpg"; }} & Lt; / Script & gt;   
 Thanks!   
 
 
 If you want to cycle through those images, I create an array and its elements Swap the position:  
  var imgs = ["2.jpg", "3.jpg", "1.jpg"]; Function change image () {document.getElementById ("imgClickAndChange"). Src = IMGS [0]; Imgs.push (imgs.shift ())}

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...
