ajax - Bootstrap typeahead suggestions replaced when navigation -

-

I'm using Bootstrap Typeahead to suggest some search results. The results are returned from an Ajax resource, and since this resource is delayed, I am having an unfortunate effect. Example: If you type 4 letter words, then suggestions will appear after two letters. I can move keys up / down through results, but sudden suggestions will be reloaded because the last request has ended.

Is there a way to "cancel" any remaining, if the user is currently using it to go through the suggestions key / up key? 

  ('# query'). Taipahed ({item: 4 Source: function (query process) {map = {}; $ getJSON ( '/ app_dev.php / ajax / autosuggest /' + query, function (data) {cars = []; $. Push (vehicle.full);}); Process (vehicle);});}, Updater: Function (item) {each] (Data, Function (i, Vehicle) {Map [vehicle.full] = Vehicles, / There is some item where the item is selected}, Highlighter: function (item) {return item;}, micht: function (item) {returns true;}});    
 
 
 I  think  will satisfy your needs (Its  
 There is no easy way to cancel the response by any delay, but you can expand the typed (without modifying bootstrap.js)  
 concept  Keydown , detect if the event is  KEY_UP  or  KEY_DOWN , set a flag  is_browsing , and then interrupt Do  process  if  is_browsing  is correct (that is, if the user hitted  KEY_UP  or  KEY_DOWN  and no other key is later).  < p>  type expansion type :  
  // original function object Save var _superTypeahead = $ .fn.typeahead; // a new flag $ .extend (_superTypeahead. Defaults, Add is_browsing as {is_browsing: False}); // to expand a new manufacturer bridesmaid Typeahead = function (element, options) to {_superTypeahead.Constructor.apply (this argument)} // prototype and add A _super function Typeahead.proto type = $ .extend ({}, _superTypeahead.Constructor .prototype, {Manufacturer: Typeahead, _super: function () {var args = $ .makeArray (logic) Bootstrap core _superTypeahead.Constructor.prototype call // [args.shift ( )] Applied (this, args)} // Ovrdraid Taipahed original Kunjeedaun, Kunjeedaun: function (e) {this._super ( 'keydown', e) this.options.is_browsing = ($ .inArray (e.keyCode, [40,38]) & gt; -1)} / / Override process, if the user is browsing, then stop: process (function) (item) {if (this.options.is_browsing) this return._super ('process', item)}}; // New Maker $ .fn.typeahead = $ .extend (function) (option) {var arg = $ .makeArray (argument), option = args.shift () // This is executed with each element Year Start Override . modal () return called Thiskeach (function () {var $ this = $ (this) var data = $ this.data ( 'Typeahead'), option = $ .extend ({}, _superTypeahead.defaults, $ This .data (), type of option == 'object' and option if (! Data) {$ this.data ('typeahead', (data = new typedhead (this, option)) if (optionof Option) == 'string') {data [options] .apply (data, args)}});}, $ .fn.typea Head);   
 This typeahead extension can be placed anywhere, for example  & lt; Script type = "text / javascript" & gt;  -section  
  Testing Extensions :  
  & lt; Input type = "text" id = "test" name = "test" placeholder = "write some text" data-provide = "typeahead" & gt; & Lt; Script type = "text / javascript" & gt; $ (Document) .ready (function () {var url = 'typeahead.php'; $ ("# test"). TypeHead ({items: 10, source: function (query, process) {return $ .get (url) ), {Query: query}, function (data) {return process (data option);})}}}};}); & Lt; / Script & gt;   
 A "serverside" PHP script that provides many random options with mandatory delays, typeahead.php:  
  & lt;? Header ('content-type: application / jason'); $ JSON = ''; Sleep (3); Execution of delay in 3 seconds for $ 3 ($ count = 0; $ count & lt; 30000; $ count ++) {if ($ JSON! = '') $ JSON = ','; // Make random wire $ s = str_shuffle ("abcdefghijklmnopq"); $ JSON = '' '$ s.' "'.} $ JSON =' {" Option ": ['. $. JSON.']} '; $ JSON echo;? & Gt;   
 This really works for me It seems, but I can not make sure that it will work in your case. If you have had success or not, then let me now.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. 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'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
