Angularjs and routeParams - javascript

I have a piece of code that is getting JSON data from a local server. I am trying to display those data into a page and then when i'll click on a product i want to see the details of it. So far i can display all my products into a page but when i'm heading to the details page i got an error Cannot read property 'id' of undefined. Can you please help me out?
This is my code so far.
app.js
'use strict';
angular.module('app', []).
config(function($routeProvider){
$routeProvider.
when("/", {templateUrl: "/partials/products.html"}).
when("/details/:id", {templateUrl: "/partials/details.html", controller: DetailsCtrl}).
otherwise({redirectTo: "/"});
})
function AppCtrl($scope, $http){
$http.get('http://localhost:3000/api/products/727617361726372')
.success(function(data){
$scope.productList = data;
/*$scope.filterProductsByCategory = function(category){
$scope.search = category
};*/
})
.error(function(data){
console.log("Error!: ");
});
}
function DetailsCtrl($scope, $routeParams){
$scope.item = $scope.productList[$routeParams.id];
}
details.html
<h2>This is the details pages</h2>
product id: {{ item.product_id }}
<br/>
product name: {{ item.product_name}}
index.html
<div class="container" ng-app="app" ng-controller="AppCtrl">
<h1 class="text-danger">Welcome to our Store</h1>
<hr/>
<ng-view></ng-view>
</div>
products.html
<div class="col-lg-4 col-sm-6 col-xs-12" ng-repeat="product in productList">
<div class="thumbnail">
<img src="img/img3.jpeg">
<div class="caption">
<h4>{{ product.product_name }}</h3>
<p>Category: {{ product.category_name }} ({{ product.category_id }})</p>
<p class="text-muted">{{ product.product_details}}</p>
<ul class="list-inline">
<li>
<p class="product-price btn">€ {{ product.product_price }}</p>
</li>
<li>
Add to Cart
</li>
</ul>
</div>
</div>
Thanks!!!

you are getting the productList in your AppCtrl. If you want to access a specific item in your DetailsCtrl you'll need to get the specific item since you can't access AppCtrl scope variables in another Ctrl.
The best way to do this would be to create an extra rest call for getting a single item.
A quick way to fix your code, although I really don't recommend it would be to use $rootcope in your AppCtrl
I'd suggest reading Angular Docs on $scope. It might give you a better understanding how scopes work in angular:
https://docs.angularjs.org/guide/scope#!

I assume you have injected ngRoute correctly.
angular.module('app', ['ngRoute'])
Other than that there is nothing wrong with your code.
Demo
Just check your code again.

How to use angular ng-repeat with an Web api?

I'm trying to build a website using front-end html and get its data from a Web-api. My Web-api returns a json format. So I was trying to use the Get request using Angular $http and ng-repeat directive. My angular controller is like this -
'use strict'; app.controller('blogsController', ['$scope','$http', function ($scope, $http) {
$http.get('www.example.com/api/blog')
.then(function(res){
$scope.blogs = res.data;
});
}]);
The html code looks like this -
<body app="ng-app" >
<div ng-repeat="xr in blogs" >
<div id="blog_title" >
{{xr.blog_title}}
</div>
<div id="blog_text">
{{xr.blog_text}}
</div>
</div>
</body>
I have tried this but this is not getting me the data from the blog web api.
Please help me to get the solution.....
there is nothing wrong in your code
<div ng-repeat="xr in blogs" >
<div id="blog_title" >
{{xr.blog_title}}
</div>
<div id="blog_text">
{{xr.blog_text}}
</div>
</div>
but make sure that your res.data must follow an arrangement like below:
res.data = [{'blog_title': 'title value1', 'blog_text':'text value'}
{'blog_title': 'title value2', 'blog_text':'text value'}
{'blog_title': 'title value3', 'blog_text':'text value'}]
print your res.data in web console using console.log to confirm.
You are missing ng-controller on the template, and app should be ng-app
<body ng-app="ng-app" ng-controller="blogsController">
<div ng-repeat="xr in blogs" >
<div id="blog_title" >
{{xr.blog_title}}
</div>
<div id="blog_text">
{{xr.blog_text}}
</div>
</div>
</body>

Filter files in folder and display them using ng-repeat (JS, Angular)

So, I've got some folder archives that contains unknown number of files, I know that:all of them got .7z extensionhalf starts with letters AB and other half - CD
So folder's content looks like:AB1234567890.7zAB2345678901.7zCD1234567890.7zCD2345678901.7z etc. That is I can do something like this:
Download
And on click it's gonna start downloading archive with name AB1234567890.7z. It's okay, but obviously I can't write links like that, it must be done with ng-repeat. So the question is - how to display 2 lists of links, where first list would be list with links which starts with AB and second - which starts with CD, respectively. Any help will be greatly appreciated :)
What about this:
angular.module('app',[]).controller('test', ['$scope', '$http', function($scope, $http){
//$http({ method: 'GET', url: '/getNames'}).then(function(names) {
// $scope.files = names;
//})
$scope.files = ['AB1234567890.7z',
'AB2345678901.7z',
'CD1234567890.7z',
'CD2345678901.7z'];
$scope.startWith = function(file, name){
return file.indexOf(name) == 0;
}
}])
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app='app' ng-controller='test'>
<p>First list</p>
<div ng-repeat='file in files' ng-if="startWith(file, 'AB')">
<a href='archives/{{file}}'>{{file}}</a>
</div>
<p>Second list</p>
<div ng-repeat='file in files' ng-if="startWith(file, 'CD')">
<a href='archives/{{file}}'>{{file}}</a>
</div>
</div>
I think this will help you
<div ng-controller="AppCtrl" layout="row" ng-cloak="" ng-app="MyApp">
<div layout="column" flex>
<a ng-repeat="file in archivesAB" href="archives/{{file}}" download="{{file}}">{{file}}</a>
</div>
<div layout="column" flex>
<a ng-repeat="file in archivesCD" href="archives/{{file}}" download="{{file}}">{{file}}</a>
</div>
</div>
(function () {
'use strict';
angular
.module('MyApp',['ngMaterial', 'ngMessages', 'material.svgAssetsCache'])
.controller('AppCtrl', AppCtrl);
function AppCtrl ($scope, $log) {
$scope.archivesAB = [
'AB1234567890.7z',
'AB2345678901.7z'
];
$scope.archivesCD = [
'CD1234567890.7z',
'CD2345678901.7z'
];
}
})();

Angular HTTP request follow link to another endpoint

I am using ng-repeat to print a list of posts to the page via the WordPress REST-API. I am using Advanced Custom Fields on each post. From what I can see everything is working, but the post data is not showing in one container, yet it is displaying in another. I should also mention that this is set up like tabs. (user clicks a tab for a post and it displays that posts data)
Here is the code:
var homeApp = angular.module('homeCharacters', ['ngSanitize']);
homeApp.controller('characters', function($scope, $http) {
$scope.myData = {
tab: 0
}; //set default tab
$http.get("http://bigbluecomics.dev/wp-json/posts?type=character").then(function(response) {
$scope.myData.data = response.data;
});
});
homeApp.filter('toTrusted', ['$sce',
function($sce) {
return function(text) {
return $sce.trustAsHtml(text);
};
}
]);
HTML:
<section class="characters" ng-app="homeCharacters" ng-controller="characters as myData">
<div class="char_copy">
<h3>Meet the Characters</h3>
<div ng-repeat="item in myData.data" ng-bind-html="item.content | toTrusted" ng-show="myData.tab === item.menu_order">
<!--this is the section that will not display-->
<h3>{{ item.acf.team }}</h3>
<h2>{{ item.acf.characters_name }} <span>[{{item.acf.real_name}}]</span></h2>
<p class="hero_type">{{ item.acf.hero_type }}</p>
{{ item.acf.description }}
Learn More
</div>
</div>
<div class="char_tabs">
<!--if I put the identical {{}} in this section it WILL display-->
<nav>
<ul ng-init="myData.tab = 0" ng-model='clicked'>
<li class="tab" ng-repeat="item in myData.data" ng-class="{'active' : item.menu_order == myData.tab}">
<a href ng-click="myData.tab = item.menu_order">
<img src="{{ item.featured_image.source }}" />
<h3>{{ item.title }}</h3>
</a>
</li>
</ul>
</nav>
</div>
</section>
I should also mention that I use Ng-inspector, and it does show the data being pulled in. I can confirm this via the console. I have checked to ensure no css is in play; the div is totally empty in the DOM.
I appreciate all the help the GREAT angular community has shown!

Books Won't Display for Reader App Exercise

I'm trying to get books to display based on the assignment above but can't figure out what is wrong for the life of me.
I built the service and modified the controller and view pages to the point where I believe they should display the books in the view, but I'm just seeing a blank page.
I feel like I am probably not retrieving the data properly and accessing it in the view/html.
Any ideas? Link to jsFiddle.
Index.html
<body ng-app="ReaderApp">
<div class="header">
<div class="container">
Reader
</div>
</div>
<div class="main">
<div class="container">
<div ng-view></div>
</div>
</div>

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

I think I had the same trouble and my problem was in the router. Try adding array brackets ( [ ] ) and the '$routeProvider' string in your config method (app.js) like this:
app.config(['$routeProvider', function($routeProvider) {
// Normal router stuff goes here
}]);
Coming from Ember, the syntax is a little weird so I've been using this tutorial as reference when I get stuck.

ng-route handling outside the scope

Edit - Added a plunkr http://plnkr.co/edit/euD4FG?p=preview
the RouteController is not getting called, please have a look
Fiddle: http://jsfiddle.net/smartdev101/tv1p9n4h/
angular.module(this.constructor.NAME, ['ngRoute'])
.config(function($routeProvider){
self.config($routeProvider)
})
.controller("RouteController", function($scope, $routeParams){
self.routeController($scope, $routeParams)})
angular.bootstrap(document.getElementById("browser"), [this.constructor.NAME]);
});
HTML
<div id="browser"></div>
<ul>
<li>
Racu, Cristian
</li>
<li>
Shnider, Brent
</li>
<li>
Suess, Mike
</li>
</ul>
Well, spell error & missing ng-view. Should be controller in $routeProverder.when, just change your config into this:
config: function($routeProvider) {
$routeProvider
.when('/attendees/:param', {
template:"no template",
//constroller: "RouteController"
controller: "RouteController"
})
},
And add ng-view into your html. Seems ngRoute won't work without ng-view
<div id="browser">
<div ng-view></div>
</div>
Here is JSFIDDLE.
