im doing small tutorial online , i'm @ point wants me display data using http controller while sample data in server file.i able pull data controller.js file when try using .get work , doesn't show data on local hose. think issue in controller.js file been few hours debugging.. not seeing issue.. i'm sure stupid.

controller.js file

    var myapp = angular.module('myapp', []);     myapp.controller('appctrl', ['$scope', '$http', function($scope,   $http)      { console.log("hello world controller");  $http.get('/savinglist').success(function(response){ console.log("got data"); $scope.savinglist = response; });   }]);

server.js file

var express = require('express'); var app = express();    app.use(express.static(__dirname + "/public"));  app.get('/savinglist', function (res, req){    console.log("i recieved request")    person1= {     name: 'tim',     price: 'tim@gmail.com',     discount:'(571) 426-1433' };  person2 = {     name:'liam',     price:'neason@taken2.com',     discount: '(777) 777-7777' };  person3={     name: 'jessie',     price:'jessie@vma.com',     discount: '(684) 426-1232' };  var savinglist = [person1, person2, person3]; res.json(savinglist); });   app.listen(3000); console.log("server running on post 3000");

index.html file

in server.js file have typo. callback function provide here needs have request object first parameter, , response second.

you wrote:

app.get('/savinglist', function (res, req){ console.log("i recieved request")

...

res.json(savinglist); });

the first line should instead read: app.get('/savinglist', function (req, res){

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
