How to display user's select choice in angularjs?
Question
How do I display an option in a paragraph
when a user selects one of the options?
Here is what I have so far:
<select ng-model="model.id" convert-to-number>
<option value="0">Soccer</option>
<option value="1">Basketball</option>
<option value="2">Tennis</option>
<option value="3">Baseball</option>
</select>
<p> Your choice is [user's choice goes here]! </p>
Basically, how would I get it to display a user's choice in a <p> ? And how do I keep it there?
If statements, switches, append? I've been stuck on how to do this
Controller:
.run(function($rootScope) {
$rootScope.model = { id: 2 };
})
.directive('convertToNumber', function() {
return {
require: 'ngModel',
link: function(scope, element, attrs, ngModel) {
ngModel.$parsers.push(function(val) {
return parseInt(val, 10);
});
ngModel.$formatters.push(function(val) {
return '' + val;
});
}
};
});

You simply bind it to a model using the binding expression {{ }} .
<p> Your choice is {{ yourModel }} </p>
This is one way binding, if you need two way binding, then you can use ng-model to bind it.
I did a simple example, I managed to get it to bind.

<!DOCTYPE html>
<html ng-app="app">

<link rel="stylesheet" href="style.css" />
<script data-require="angular.js@1.4.1" data-semver="1.4.1" src="https://code.angularjs.org/1.4.1/angular.js"></script>
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<select ng-model="model.id" convert-to-number="" selected="selected">
<option value="0">Soccer</option>
<option value="1">Basketball</option>
<option value="2">Tennis</option>
<option value="3">Baseball</option>
</select>
<p> Your choice is {{ model.id }}! </p>
</body>
</html>
JS
(function() {
"use strict";
var app = angular.module("app", []);
app.controller("MainController", ["$scope", MainController]);
function MainController($scope) {
$scope.model = {
id: 1
};
}
}());
