How can I disable double click on Jquery Modal Dialog button? -

-

let me know I am using the jquery model dialog after depositing some data in the server side and saving it in the database; Here is my modal dialog code: 

  function loadUserDialog (tag, event, target, id) {event.preventDefault (); $ .validator.unobtrusive.parse ('# frmModalPopup'); Var $ loading = $ ('& lt; img src = "@ Url.Content (" ~ / content / images / ajaxLoading.gif ")" alt = "loading" class = "ui-loading-icon" style = "margin : 150px 150px; "& gt; '); Var $ url = $ (tag) .attr ('href'); Var $ title = $ (tag) .attr ('title'); Var $ dialog = $ ('
 & lt; / div & gt;'); $ Dialog.empty (); $ Dialog Append ($ loading) .load ($ url) .dialog ({autoOpen: false, title: $ title, width: 500, model: true, minhite: 400, show: 'fade', hide: 'fade'}); $ Dialog.dialog ("option", "button", {"submit": function () {var dlg = $ (this); if (IsValidUserName ()) and $ ('# frmModalPopup') is valid () .form ()) {$. Ajax ({url: $ url, type: 'post', data: $ (target). Serialize (), success: function (response) {var cid = $ (response) .attr ('id'); if (cid ! = Null & cid! = Undefined) {$ (North). FadeIn ('slow') .adv; $ (window) .scrollTop ($ ('(' # '+ cid) .offset () ; Top);} dlg.dialog ('close'); dlg.empty ();}, error: function (xhr) {alertMessage ("Email ID is already in use!"); $ Validator.unobtrusive.parse ( '# FrmModalPopup');}})}}} "Cancel": function () {$ (this) .dialog ('close'); $ (this) .empty ();}}); $ Dialog.dialog ('open'); };   
 But when I click on more than one click on the Submit button (more than once), the form gets accumulated more than once and I get duplicate data submission information. Can you please tell me how to double click or click the Disable multiple buttons button. Disable 
 
 Check on previously submitted dialog, check that it is disabled before proceeding. Given, come back if already disabled.  
  "submit": function () {if ($ (this) .hasClass ("disabled")) return; $ (This) .addClass ("disabled"); // to continue; }   
 Edit: When you disable it, you can use this approach to add some additional user interface accountability by adding "working ..." or any other message  
  $ (this) .addClass ("disabled"); $ Dialog.append ("Working ...");

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
