Form and Ng-Submit in Angular Js

Form and Ng-Submit in Angular Js

In this blog, I’m explaining how to create a form and submit it using the angular js.

Example


First create an index.html page and the reference of angular.min.js file like this:


<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Ngsubmit</title>
   <script src="~/Scripts/angular.min.js"></script>
<body>
</body>
</html>


Now add the <script> tag in the head section of the page write the following code:

<script>
        var app = angular.module("myApp", []);

        app.controller("myController", function ($scope) {
            $scope.names = [{ name: "Sumit" }];

            $scope.addValue = function () {
                $scope.names.push($scope.newData);
                $scope.newData = '';
            }
        });

    </script>


Here I have create the controller named “myController”, and it has one property names which is an array and a method addValue() : used to add the value in the names.


Now in the <body> tag :

<body ng-controller="myController as ctrl">
    <div>
        <div>
            <ul>
                <li ng-repeat="n in names">{{$index + 1}} - {{n.name}}</li>
            </ul>
            <p>Total Entry : {{names.length}}</p>
        </div>
        <div>
            <form ng-submit="addValue()">
                <input type="text" ng-model="newData.name" />
                <input type="submit" value="add" />
            </form>
        </div>
    </div>
</body>


In the <body> add the “myController” controller using the ng-controller directive.

Ng-repeat directive will display all the values in the names.

$index will show the index of the object in the array. It starts with 0.

In the angular expression, names.length will display the total number of objects in the array.

Ng-submit directive will submit the form to the addValue() method.

Output

Run the application:



Enter any name in the textbox and click on add button:






This will add the name in the array.
