     var app = angular.module('myapply.directives', [], function () { }); app.directive('numericdecimalinput', function($filter, $browser, $locale,$rootscope) {          return {                 require: 'ngmodel',                 priority: 1,                 link: function($scope, $element, $attrs, ngmodelctrl) {                     var replaceregex = new regexp($locale.number_formats.group_sep, 'g');                     var fraction = $attrs.fraction || 0;                       var listener = function() {                         var value = $element.val().replace(replaceregex, '');                         $element.val($filter('number')(value, fraction));

could 1 please let me know missing . thanking in advance.

have declared app (doesn't show in code)? ie:

var app = angular.module('app', []);

do have ng-app in html document anywhere?

<html lang="en-gb" ng-app="app">

check out documentation started modules (angular documented, worth reading): https://docs.angularjs.org/guide/module

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
