How to access elements from a javascript array for an email sent with PHP/HTML -

-

So I'm working on a webpage that generates a JavaScript array from the date element of HTML.

This array works fine on its own, and I can print it on a webpage using a command like this: 

  document.getElementById ("demo "). = Week [0];   
 To access the generated "Week" array in JavaScript and paste it into the HTML Span element on the webpage  
 However, it is a webpage that stores data I can not confirm how to get data from this javascript array for email  < P> email notifications PHP is formatted using PHP with PHP variables. I thought of using a php array, but I think that whatever solution I am getting for it is either for some other matter or so complex  
 - I have the ability to copy this JavaScript array into a PHP array, which I would like to break and repurpose.  
 Can use for email The front.  
 - The ability to use this JavaScript array within the HTML for the email  
 This is all contained within a PHP file on the server (HTML markup, JavaScript functions and PHP) < / P> 
  
  Edit:  I found this thread: and tried your solution with this code:  
 Javascript:  
  JSON.stringify (week);   
 PHP:  
  $ datesOfWeek = json_decode ($ _ POST ['week']);   
 But whenever I try to reach the elements of the array and print them in the email, I do not print anything for these elements.   
 
 
 I'm not sure what you want to achieve, but if you want to send data from JS With the form data (on the customer) php script (on the server) you should just sort your array and put it as the value of the additional (hidden) form field. In the PHP script, you can somehow deselect the value of that field (it depends on the format of your choice)  
 // Edit: Here is a JS Script example that you can use  
  var myArrayToSend = ["val1", "val2"] var arrayField = document.query selector ("[name = JSRRA]"); Arrayfield.value = JSON.stringify (myArrayToSend)   
 On the server side you only need to deserialize the value of $ _POST ["jsArray"] (use json or library for simple regex Please). Instead of JSON.stringify you can use myArrayToSend.join (";") and then use the partitioning method in pho to "deserialize" that string.

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...
