Angular - Use Form Post Values In Controller
I'm writing my first application in AngularJS, and I'm new to javascript. I have a simple question: How do I use POST values from an html form in an angular controller? I have a
Solution 1:
When you set the input with ng-model="email", then you can access those variable values in controller by just calling $scope.email.
Case-1: For single value
HTML
<input type="text" ng-model="email" />
Angular Controller
console.log($scope.email);
Case-2: For multiple values
HTML
<input type="text" ng-model="user.firstname" />
<input type="text" ng-model="user.lastname" />
<input type="text" ng-model="user.email" />
Angular Controller
//This will print the all the values (firstname, lastname, email) contains user as object.
console.log($scope.user);
Please check this working snippet to see the real time example
var app = angular.module('myApp', []);
app.controller('FormCtrl', function ($scope, $http) {
$scope.user = {};
$scope.signup = function(){
console.log($scope.user);
}
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp">
<form name="signupForm" ng-controller="FormCtrl" ng-submit="signup()">
<input type="text" placeholder="Name..." ng-model="user.name" name="name" required />
<input type="email" name="email" ng-model="user.email" placeholder="Email..." required>
<input type="password" placeholder="Password..." ng-model="user.password" name="password" required ng-minlength="7" ng-maxlength="50"/>
<button type="submit">Sign Up</button>
</form>
</body>Solution 2:
You need to use $scope for binding ng-model's value as shown as follow...
$scope.signup = function() {
data={
name: $scope.name,
email: $scope.email,
password: $scope.password
}
$http.post('http://myapi.com/api/authenticate/signup',data).then(function(response) {
// etc
});
Solution 3:
HTML
<form name="signupForm" novalidate>
<input type="text" placeholder="Name..." ng-model="user.name" name="name" required />
<input type=“email" name="email" ng-model="user.email" placeholder="Email..." required>
<input type="password" placeholder="Password..." ng-model="user.password" name="password" required ng-minlength="7" ng-maxlength="50"/>
<button type="button" ng-click="auth.signup()">Sign Up</button>
JS
function SignupController($http, $scope, $rootScope, $location) {
$scope.user={};
vm.signup = function(name, email, password, onSuccess, onError) {
$http.post('http://myapi.com/api/authenticate/signup',
{
name: $scope.user.name,
email: $scope.user.email,
password: $scope.user.password
}).then(function(response) {
// etc
Solution 4:
In your html
<form name="signupForm" novalidate ng-submit="vm.signup()">
<input type="text" placeholder="Name..." ng-model="name" name="vm.user.name" required />
<input type=“email" name="email" ng-model="vm.user.email" placeholder="Email..." required>
<input type="password" placeholder="Password..." ng-model="vm.user.password" name="password" required ng-minlength="7" ng-maxlength="50"/>
<button type="submit">Sign Up</button>
</form>
In your controller
function SignupController($http, $scope, $rootScope, $location) {
vm.user = {};
vm.signup = function() {
// validate here
// send data
$http
.post('http://myapi.com/api/authenticate/signup', vm.user)
.then(function(response) {
// handle success
});
};
}
Solution 5:
Three ways you can do
Type 1 With individual params
HTML
<form name="signupForm" novalidate>
<input type="text" placeholder="Name..." ng-model="name" name="name" required />
<input type="email" name="email" ng-model="email" placeholder="Email..." required />
<input type="password" placeholder="Password..." ng-model="password" name="password" ng-minlength="7" ng-maxlength="50" required/>
<button type="button" ng-click="auth.signup(name, email, password)">Sign Up</button>
</form>
JS
vm.signup = function(name, email, password) {
$http.post('http://myapi.com/api/authenticate/signup',
{
name: name,
email: email,
password: password
}).then(function(response) { });
}
Type 2 With object as param
HTML
<form name="signupForm" novalidate>
<input type="text" placeholder="Name..." ng-model="user.name" name="name" required />
<input type="email" name="email" ng-model="user.email" placeholder="Email..." required />
<input type="password" placeholder="Password..." ng-model="user.password" name="password" ng-minlength="7" ng-maxlength="50" required/>
<button type="button" ng-click="auth.signup(user)">Sign Up</button>
</form>
JS
vm.signup = function(data) {
$http.post('http://myapi.com/api/authenticate/signup', data)
.then(function(response) {
});
}
Type 3 Using $scope
HTML
<form name="signupForm" novalidate>
<input type="text" placeholder="Name..." ng-model="user.name" name="name" required />
<input type="email" name="email" ng-model="user.email" placeholder="Email..." required />
<input type="password" placeholder="Password..." ng-model="user.password" name="password" ng-minlength="7" ng-maxlength="50" required/>
<button type="button" ng-click="auth.signup()">Sign Up</button>
</form>
JS
vm.signup = function() {
$http.post('http://myapi.com/api/authenticate/signup', $scope.data)
.then(function(response) {
});
}
It will work in all these ways.
