Angular / ionic - model doesn't update $ scope in controller
I'm new to angularjs and I'm trying something that I believe should be very simple ... but it turns out I don't understand.
I have a variable $scope
that I want to double binding (using ng-model
) to a text area. I was able to get it to work on the js fiddle sites, but now on my code. I tried to expand everything down to a few lines and it still doesn't work, the controller never gets updated.
this is my code:
Js / main.js
var app=angular
.module('noclu', ['ionic', 'app.controllers'])
.config(function ($stateProvider, $urlRouterProvider){
$stateProvider
.state('menu.main', {
url: "/main",
views: {
'menuContent': {
templateUrl: 'templates/main.html',
controller: 'MainCtrl'
}
}
});
$urlRouterProvider.otherwise("/menu/main");
});
Js / controller.js
angular
.module('app.controllers', [])
.controller('MainCtrl', function ($scope){
$scope.src='---';
$scope.get_feeds=function(){
//seems like that here "this" is actually the textarea ??
//$scope.src is always whatever has been set in the controller
console.log('this:'+this.src); //this output whatever I enter in the textarea
console.log('scope:'+$scope.src); //this always output '---'
};
});

<div class="padding src-title">What are you in the mood for ?</div>
<div class="item" id="src-txt-wrapper">
<textarea id="src" ng-model="src"></textarea>
</div>

UPDATE - I got it working, but why?
I got it working by changing $scope.src='---';
to $scope.src={body:'---'};
and then changing ng-modal
to src.body
. but .. WHY didn't it work differently, since it works for boolean?

Using $ scope directly. not good practice in angularJS. There are different positions, it is more appropriate to inherit from $ scope. For example: http://learnwebtutorials.com/why-ng-model-value-should-contain-a-dot
Therefore, you need to change your model like this:
$scope.myModel = {};
$scope.myModel.src = "---"
And your html to bind to myModel.src
