How to set the input field value dynamically in AngularJS ?

Last Updated : 30 Jul, 2024

Given an input field and the task is to set the input field value dynamically with the help of AngularJS.

Approach:

A value is being set to the input field despite the user enter something or not.
ng-click event is used to call a function that sets the value to 'This is GeeksForGeeks' with the help of ng-model.

Example 1: In this example, the input field is read-only So the user can not modify it and the value is set dynamically.

<html>

<head>
    <script src=

    </script>

    <script>
        var myApp = angular.module("app", []);
        myApp.controller("controller", function ($scope) {
            $scope.nameText = '';
            $scope.setVal = function () {
                $scope.nameText = "This is GeeksForGeeks";
            };
        });
    </script>
</head>
