javascript - How I can add a counter after adding a new - to my list using jquery -

-

After adding a new row at the top of my list, I try to apply a dynamic counter to add to my list The code is not working properly because it is wrong, for example if we have this list

  1. A
  2. b

  3. And I will add D instead of making it like this

    1. D
    2. A
    6. A
    7. Come
    8. c

      Relationship I want to delete the last line if I down a new line add, but what is not working no one knows why?

      A A variable that holds the content that I want to prepaid 

        $ (". Il_admin -" + id) .prepend (html) .slideDown ("slow"), a ???? Var i = GetURLParameter ("paged"); Var calculation = (i * 10) -10; JQuery ("Il_admin li"). Each (function (i) {i = count + i; var text_attreibute = $ (this) .find (".l_admin_raw_count"); $ (text_attreibute) .html (i + 1);}); Var size = $ ('. Il_admin li') Size (); If (size> 10) {var last_row = $ ('. Il_admin li'). last (). Attr ('class'); $ (LAST_ROW) .remove (); }    
       
       
        jQuery (".l_admin li") each. (Function) {Var text_attreibute = $ (this) .find (".l_admin_raw_count"); $ (This) .html (parseInt ($ (this) .index ()) + 1 + '.' + Text_attreibute);});   
       Since you voted for a long time, you have to force an audience on your list change to refresh the pointer. Try it:  
        jQuery (document) .on ("change", ".il_admin", function (i, list_li) {// will call your DOM every time in your .il_admin Change (= you've added a new line) $ (list_li) .each (function (j, li) {var text_attreibute = $ (li) .find (". Il_admin_raw_count") var output = parseint ($ (li) Index ()) + 1 + '.' + Text_attreibute; if (output! = $ (.html)). Html again and Are our listeners say again $ (li). HTML (output);}}}.

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...
