Lets use some of the AngularJS features to make a shopping list, where you can add or remove items:
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css">
<body>
<script>
var app = angular.module("myShoppingList", []);
app.controller("myCtrl", function($scope) {
$scope.items = ["Milk", "Bread", "Cheese"];
$scope.addItem = function () {
$scope.errortext = "";
if (!$scope.addMe) {return;}
if ($scope.items.indexOf($scope.addMe) == -1) {
$scope.items.push($scope.addMe);
} else {
$scope.errortext = "The item is already in your shopping list.";
}
}
$scope.removeItem = function (x) {
$scope.errortext = "";
$scope.items.splice(x, 1);
}
});
</script>
<div ng-app="myShoppingList" ng-cloak ng-controller="myCtrl" class="w3-card-2 w3-margin" style="max-width:400px;">
<header class="w3-container w3-light-grey w3-padding-16">
<h3>My Shopping List</h3>
</header>
<ul class="w3-ul">
<li ng-repeat="x in items" class="w3-padding-16">{{x}}<span ng-click="removeItem($index)" style="cursor:pointer;" class="w3-right w3-margin-right">×</span></li>
</ul>
<div class="w3-container w3-light-grey w3-padding-16">
<div class="w3-row w3-margin-top">
<div class="w3-col s10">
<input placeholder="Add shopping items here" ng-model="addMe" class="w3-input w3-border w3-padding">
</div>
<div class="w3-col s2">
<button ng-click="addItem()" class="w3-btn w3-padding w3-green">Add</button>
</div>
</div>
<p class="w3-text-red">{{errortext}}</p>
</div>
</div>
</body>
</html>
