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.
<!DOCTYPE HTML>
<html>
<head>
<script src=
"https://ajax.googleapis.com/ajax/libs/angularjs/1.2.13/angular.min.js">
</script>
<script>
var myApp = angular.module("app", []);
myApp.controller("controller", function ($scope) {
$scope.nameText = '';
$scope.setVal = function () {
$scope.nameText = "This is GeeksForGeeks";
};
});
</script>
</head>
<body style="text-align:center;">
<h1 style="color:green;">
GeeksForGeeks
</h1>
