javascript - Delay on Form setvalidity in AngularJS -


i using directive on setting form validity. works accordingly boolean value of custom validity not return right away , exact needs keypress. way i'm using 'element.blur' setting custom validity.

here html code:

<!doctype html> <html ng-app="myapp">    <head>     <link rel="stylesheet" type="text/css" href="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">     <link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1/themes/flick/jquery-ui.min.css">     <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>     <script type="text/javascript" src="https://code.jquery.com/ui/1.11.2/jquery-ui.min.js"></script>     <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.9/angular.min.js"></script>     <script src="script.js"></script>   </head>    <body>       <form ng-controller="myctrl" name="biomanagementform" novalidate>         <fieldset ng-repeat="bioeducation in bioeducations" data-ng-form="nestedbioeducationsform">           degree: <br />           availability: -- {{ nestedbioeducationsform.bio_education_degree.$error.available }}           <input class="form-control input-form" ng-model="bioeducation.bio_education_degree" name="bio_education_degree" id="bio_education_degree" auto-complete-validation ui-items="searchdegreeitems">           <span class="errors" id="error-bio-education-degree">                         <span ng-if="nestedbioeducationsform.bio_education_degree.$error.available"> * not available <br /></span>                     </span>                     school: <br />                     availability: -- {{ nestedbioeducationsform.bio_education_school.$error.available }}                     <input class="form-control input-form" type="text" ng-model="bioeducation.bio_education_school" name="bio_education_school" id="bio_education_school" auto-complete-validation ui-items="searchschoolitems">           <span class="errors" id="error-bio-education-school">                         <span ng-if="nestedbioeducationsform.bio_education_school.$error.available"> * not available <br /></span>                     </span>         </fieldset>     </form>   </body> </html>

here js code:

// code goes here  var myapp = angular.module('myapp', []);    myapp.controller('myctrl', function($scope){   $scope.name = "dean";   $scope.originalbioeducations = [{}];     $scope.bioeducations = angular.copy($scope.originalbioeducations);     $scope.searchschoolitems = ["don bosco", "jru", "ust", "feu"];     $scope.searchdegreeitems = ["bsit", "bsed", "ece", "coe"]; });  function monkeypatchautocomplete() {     // don't need save old fn,      // chain if wanted     var oldfn = $.ui.autocomplete.prototype._renderitem;      $.ui.autocomplete.prototype._renderitem = function( ul, item) {         var re = new regexp( "(" + this.term + ")", "gi" );         var t = item.label.replace(re,"<span style='font-weight:bold;color:#04508e;'>" + this.term + "</span>");         return $( "<li></li>" )         .data( "item.autocomplete", item )         .append( "<a>" + t + "</a>" )         .appendto( ul );     }; }  monkeypatchautocomplete(); function remove_duplicates_safe(arr) {         var obj = {};         var arr2 = [];         (var = 0; < arr.length; i++) {             if (!(arr[i] in obj)) {                 arr2.push(arr[i]);                 obj[arr[i]] = true;             }         }         return arr2;     }   myapp.directive('autocompletevalidation', function($timeout){         return {             require: 'ngmodel',             scope: {                 uiitems: "="             },             link: function(scope, element, attrs, ctrl){                 scope.$watchcollection('uiitems', function(val){                     items = scope.uiitems.filter(function(n){ return n != undefined });                     element.autocomplete({                         source: remove_duplicates_safe(items),                         minlength:2,                     });                     element.bind('blur', function(){                         _val = element.val();                         _index = items.indexof(_val);                         if(_index == -1){                             ctrl.$setvalidity('available', false);                             console.log("dean");                         }else{                             ctrl.$setvalidity('available', true);                             console.log("armada");                         }                     });                 });             }         }     });

p.s.

the app dynamic field via ng-repeat. using data-ng-form dynamic validations well. both input fields run jquery ui autocomplete. validation should detect if value on field in autocomplete choices inside array(the 1 "items" scope variable). should throw error if 1 on input field not in choices.

here example in plunkr: http://plnkr.co/edit/2epuhrir9oncv8z7q018?p=preview

if want avoid adding keypress event should use $validators object property on ngmodelcontroller. correct way create validator directive anyway. might want add change event autocomplete, can $setviewvalue.

               scope.$watchcollection('uiitems', function(val){                 items = scope.uiitems.filter(function(n){ return n != undefined });                 element.autocomplete({                     source: remove_duplicates_safe(items),                     minlength:2,                     change: function () {                       ctrl.$setviewvalue(element.val());                     }                 });             });              ctrl.$validators.available = function (modelvalue, viewvalue) {               var value = modelvalue || viewvalue;               if (items) {               var _index = items.indexof(value);                return _index !== -1;               }             }

btw. don't create global variables on fly, adding _ @ beging of name not make them local or private.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
