Switching Angular view not updating variables
I am just building a simple app to find out AngularJS
and problems updating variables when switching views. Here's what I have so far:
function routeConfig($stateProvider, $urlRouterProvider) {
$stateProvider
.state('home', {
url: '/',
templateUrl: 'app/main/main.html',
controller: 'MainController',
controllerAs: 'main'
})
.state('team', {
url: '/team',
templateUrl: 'app/main/team.html',
controller: 'MainController',
controllerAs: 'main'
})
$urlRouterProvider.otherwise('/');
}
Here's a part of my controller:
function MainController($timeout, webDevTec, toastr, $resource, $scope) {
var vm = this;
var GetTeam = $resource('https://apisite.com/api_endpoint/:teamId', {teamId: '@id'});
vm.teamName = '';
function getTeamInfo(id) {
var teamObj = GetTeam.get({teamId: id});
$timeout(function(){
vm.teamName = teamObj["name"];
},100)
};
vm.getTeamInfo = getTeamInfo;
}
Then, in my main.html, I call getTeamInfo with ng-click:
<ul class="list-group">
<li class="list-group-item" ng-repeat="team in main.teams" ng-click="main.getTeamInfo(team.id)"><a href="#/team">{{ team.name }}</a></li>
</ul>
Clicking on this link will take you to the team.html command:
<div class="row">
<div class="col-sm-12">
<h3>{{ main.teamName }}</h3>
<ul class="list-group">
. . .
</ul>
</div>
</div>
For some reason " main.teamName
" is not updated. I have also tried the approach $scope.$apply(function(){vm.teamName = teamObj["name"]}
but no luck. I also did " console.log(teamObj["name"])
" before vm.teamName
and 'console.log(vm.teamName)'
after I get the expected results, and I will. I just have no idea why this is not updating the new view.
Thank you for your understanding, patience and time!
UPDATE 1
I also tried using $ scope for my variables ($ scope.teamName) and using $ scope. $ apply (function () {$ scope.teamName = teamObj ["name"]}) with no luck.
UPDATE 2
I also tried calling $ scope. $ apply (); after 'vm.teamName = teamObj ["name"]' no luck

It looks like it teamObj
is not filling yet at the point when you assignvm.teamName
You would make your life a lot easier if you just referenced teamObj
instead of creating a new property.
I made a plunker based on a modified version of your code to show a possible implementation. I couldn't get it to work with the controllerAs syntax , and I'm not entirely sure why (maybe due to some controller sharing issues, not sure). Anyway, I hope you find this helpful.
app.js
var app = angular.module('plunker', ['ui.router', 'ngResource']);
app.controller('MainController', MainController);
app.config(routeConfig);
function MainController($timeout, $scope, $resource) {
// mock data
var GetTeam = $resource('http://demo7592070.mockable.io/teams/:teamId', {teamId: '@id'});
//var GetTeam = $resource('https://apisite.com/api_endpoint/:teamId', {teamId: '@id'});
$scope.teamName = 'undefined';
$scope.getTeamInfo = getTeamInfo;
function getTeamInfo(id) {
var teamObj = GetTeam.get({teamId: id});
$scope.teamName = teamObj.name;
$scope.teamObj = teamObj;
};
}
function routeConfig($stateProvider, $urlRouterProvider) {
$stateProvider
.state('home', {
url: '/',
templateUrl: 'main.html',
controller: 'MainController'
})
.state('team', {
url: '/team',
templateUrl: 'team.html',
controller: 'MainController'
});
console.log('ROUTECONFIG');
$urlRouterProvider.otherwise('/');
}
