javascript - parent id lost on submit -

-

For some reason, when I submit my form after starting the changing event, the parent ID will now include the ID The database does not have to be inserted. Instead it includes 'Selection Event'? Do I miss something?

Form 

  & quot; Class = "form-control" id = "parent_id" name = "parent_id" & gt; & Lt; Options & gt; Select event & lt; / Options & gt; $ Foreach (Event :: All () as $ item) & lt; Option value = "{{$ item-& gt; id}}" & gt; {{$ Item- & gt; Title}} & lt; / Option & gt; @earnchach & lt; / Select & gt; & Lt; Div id = "child_id" & gt; & Lt; / Div & gt;   
 JAVASCRIPT  
  
  $ (document) .ready (function ($) {$ ('# parent_id'). ( Function () {$ .getJSON ("{{url ('api / dropdown')}}, {option: $ (.) .val ()}, function (data) {if (data.success == true) ( $ ('# Busy'). ($), $ .eight (data, function (key, value) {$ ('# child_id'). Append ('
' + value.name + '   
 
 
 As far as I understand that  select  of all your  options  are adding to the running time, post the value At the time of doing only the default option with one item If you use a hidden field as  
  & lt; input type = "hidden" id = "hiddenvalue" & gt; & lt; / input & gt;   
 and assign an event to the selected change that the selected values ​​will be hidden in the field  
  $ ("# parent_id") ("Change", function () {var $ select = $ (this); $ ("# Hidden value") Val ($ select.val ());});   
 Instead of choosing to take value from hidden fields.  
 Hope it helps ..........

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...
