AngularJS Question

add an object declared on the controller in Angular JS

i am an angularJS beginner and i have an issue.
I want to add data to a media-object in html using an object declared in the script inside the controller, but i can't find which directive i must use.

Here is the code:



<!DOCTYPE html>
<html lang="en" ng-app="confusionApp">

<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- The above 3 meta tags *must* come first in the head; any other head
content must come *after* these tags -->
<title>Ristorante Con Fusion: Menu</title>
<!-- Bootstrap -->
<link href="../bower_components/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet">
<link href="../bower_components/bootstrap/dist/css/bootstrap-theme.min.css" rel="stylesheet">
<link href="../bower_components/font-awesome/css/font-awesome.min.css" rel="stylesheet">
<link href="styles/bootstrap-social.css" rel="stylesheet">

this.dish = dish;

});

Could someone help me? I think it's something easy but know I have collapsed!

Thank you

Answer

You have at least 2 options.

Option 1: Use $scope. This will make sure your html remains unchanged

app.controller('dishDetailController', function($scope) {
   // Your dish declaration
   $scope.dish = dish;
 });

Option 2: Javascript remains unchanged. In HTML, prefix dish with dishCtrl since you use dishDetailController as dishCtrl

Ex: Instead of <img class="media-object img-thumbnail" ng-src={{dish.image}} alt="Uthapizza">, use

<img class="media-object img-thumbnail" ng-src={{dishCtrl.dish.image}} alt="Uthapizza">
