Use only
ngClick. Also you don't need to pass it as parameter. – developer033 Commented Aug 3, 2016 at 6:28

Reset to default 2Try this , its working
You can use angular.element(document.getElementById("Text1")) to get value from javascript. And this value set to scope variable.
No need to send any value to function since textbox is scope value.
$scope.pset = function(){
var x=angular.element(document.getElementById("Text1"));
$scope.textbox = x.val();
alert($scope.textbox);
}
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.pset = function(){
var x=angular.element(document.getElementById("Text1"));
$scope.textbox = x.val();
alert($scope.textbox);
}
});<script data-semver="1.4.9" src="https://code.angularjs/1.4.9/angular.js" data-require="[email protected]"></script>
<script>
window.onload=function(){
// document.getElementById("Text1").value = "Johnny Bravo";
}
function myFunction() {
document.getElementById("Text1").value = "Johnny Bravo";
}
</script>
<body ng-app="plunker" ng-controller="MainCtrl">
<input type='text' ng-model='textbox' name='textbox1' id='Text1'>
<button onclick="myFunction()" ng-click="pset()">set value</button>
</body> View page:
<div class="col-md-6 col-md-offset-3">
<h2>Login</h2>
<form name="form" ng-submit="vm.login()" role="form">
<div class="form-group" ng-class="{ 'has-error': form.username.$dirty && form.username.$error.required }">
<label for="username">Username</label>
<input type="text" name="username" id="username" class="form-control" ng-model="vm.username" required />
<span ng-show="form.username.$dirty && form.username.$error.required" class="help-block">Username is required</span>
</div>
<div class="form-group" ng-class="{ 'has-error': form.password.$dirty && form.password.$error.required }">
<label for="password">Password</label>
<input type="password" name="password" id="password" class="form-control" ng-model="vm.password" required />
<span ng-show="form.password.$dirty && form.password.$error.required" class="help-block">Password is required</span>
</div>
<div class="form-actions">
<button type="submit" ng-disabled="form.$invalid || vm.dataLoading" class="btn btn-primary">Login</button>
<a href="#!/register" class="btn btn-link">Register</a>
</div>
</form>
</div>
In controller :
(function () {
'use strict';
angular
.module('app')
.controller('LoginController', LoginController);
LoginController.$inject = ['$location', 'AuthenticationService', 'FlashService'];
function LoginController($location, AuthenticationService, FlashService) {
var vm = this;
vm.login = login;
function login() {
vm.dataLoading = true;
AuthenticationService.Login(vm.username, vm.password, function (response) {
if (response.success) {
AuthenticationService.SetCredentials(vm.username, vm.password);
$location.path('/');
} else {
FlashService.Error(response.message);
vm.dataLoading = false;
}
});
};
}
})();
