javascript - Call a changing variable from outside the function -

- 

var slider = document.getelementbyid('test5'); nouislider.create(slider, {     start: [1366],     step: 1,     range: {         'min': 200,         'max': 1920     },     format: wnumb({         decimals: 0,         postfix: 'px',     }) });  var app = angular.module('myapp', []);  app.controller('mywidth', function ($scope) {     $scope.width = inputformat.value;      $scope.$watch('width', function (newvalue, oldvalue) {         console.log('old:' + oldvalue);         console.log('new:' + newvalue);     });     console.log($scope.width + ' - scope width'); }); var inputformat = document.getelementbyid('input-format'); editorcontainer = document.getelementbyid('editorcontainer'); slider.nouislider.on('update', function (values, handle) {     inputformat.value = values[handle];     //$(editorcontainer).css('width', values[handle]); }); inputformat.addeventlistener('change', function(){     slider.nouislider.set(this.value); });

i having problem getting value of inputformat on constant basis. happens run webpage/application , $scope.width variable gets first value of inputformat , stops. doesn't continue value after value of inputformat has changed. question how call inputformat variable in way $scope.width variable gets updated? new angular , javascript, , can understand question. help!

here part of html call $scope.width:

<div class="" <!--id="editorcontainer"--> style="position: absolute; top: 10px;    bottom: 10px; right: 10px; left: 10px; width: {{width}};"

you should use ng-style , change $scope.width..

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
