How I can set val1 to $_POST variable ? Because in step 2 val1 is null.
I try to use $scope, $rootScope, angular.copy() and .val().
This is my html code:
<html ng-app="myApp"><body>
<form action="url.php" method="POST" ng-controller="FormController as vmForm">
<div ng-switch="vmForm.step">
<div class="stepone" ng-switch-when="one">
<label for="val1">Val1</label>
<input type="text" name="val1" ng-model="val1">
<button type="button" ng-click="vmForm.stepTwo()"></button>
</div>
<div class="steptwo" ng-switch-when="two">
<label for="val2">Val2</label>
<input type="text" name="val2" ng-model="val2">
<input type="submit" value="Submit">
</body>
JS
<script>
angular.module('myApp', ['ngAnimate'])
.controller('FormController', FormController);
function FormController($scope) {
var vm = this;
vm.step = "one";
vm.stepTwo = stepTwo;
function stepTwo() {
vm.step = "two";
}
}</script>
$_POST is a PHP variable that's accessible on the server. It contains the payload or request body that's sent in a HTTP POST request as an associative array. It cannot be set directly using Javascript / AngularJS.
What you can do is construct your request data and make a $http POST request to your form action endpoint. Here's a working example based on the code you posted: http://plnkr.co/edit/C1FGvoDrmzYEFMCwymIG?p=preview
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.1/angular.min.js"></script>
<script src="script.js"></script>
</head>
<body ng-app="myApp">
<h1>Hello Plunker!</h1>
<form ng-submit="formSubmit()" ng-controller="FormController">
<p>Val1: {{val1}}</p>
<p>Val2: {{val2}}</p>
<div ng-switch="vm.step">
<div class="stepone" ng-switch-when="one">
<label for="val1">Val1</label>
<input type="text" name="val1" ng-model="$parent.val1">
<button type="button" ng-click="stepTwo()">Go to Step two</button>
</div>
<div class="steptwo" ng-switch-when="two">
<label for="val2">Val2</label>
<input type="text" name="val2" ng-model="$parent.val2">
<input type="submit" value="Submit">
</div>
</div>
</form>
</body>
</html>
script.js
var app = angular.module('myApp', []);
app.controller('FormController', ['$scope','$http',function ($scope,$http) {
$scope.vm = {
step : "one"
};
$scope.val1 = "";
$scope.val2 = "";
$scope.stepTwo = function () {
$scope.vm.step = "two";
}
$scope.formSubmit = function () {
console.log($scope.val1, $scope.val2);
var req = {
url : 'url.php',
method: 'POST',
data : {
val1 : $scope.val1,
val2 : $scope.val2
}
};
$http(req).then(function(response) {
console.log('success', response);
}, function(errorResponse){
console.log('error', errorResponse);
});
}
}]);
Just leave everything as is in your controller and tweak your HTML like this:
<form action="url.php" method="POST" ng-controller="FormController as vmForm">
<div ng-switch="vmForm.step">
<div class="stepone" ng-switch-when="one">
<label for="val1">Val1</label>
<input type="text" name="val1" ng-model="vmForm.val1">
<button type="button" ng-click="vmForm.stepTwo()">Goto Step 2</button>
</div>
<div class="steptwo" ng-switch-when="two">
<input type="hidden" name="val1" value="{{vmForm.val1}}">
<label for="val2">Val2</label>
<input type="text" name="val2" ng-model="val2">
<input type="submit" value="Submit">
</div>
</div>
</form>
The tweak to your code is simply raising the scope of "val1" to "vmForm.val1" so in Step 2 "vmForm.val1" can be assigned to a hidden input field for posting.
Here's the form fields being posted in the browsers debugger:

I'm trying to open a modal when i click the button. I made comment line the other part which i'm using but it works fine. The second part is for only the modal but it is not working. I even can not open the modal. If there is a basic way to do this can you share with me? I only need to open this modal. I can handle the rest of it.
From the Docs:
There are a few things to keep in mind when using ngApp:
only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application. To run multiple applications in an HTML document you must manually bootstrap them using angular.bootstrap instead.
For more information, see
AngularJS ng-app Directive API Reference
It's maybe a stupid question but it's late and i'm desperate.
I have a angularjs application that uses ngRoute. But everything is done in one controller. Now I have a form in a view and the use of that form is to put it's input field data into a var to send with post.
Don't mind al the console log i'm trying to find the error.
APP.JS
`
$scope.addDevice = function(){
$scope.device = {};
var data = {
'Name' : $scope.device.ChildName,
'Serial' : $scope.device.Serial
};
console.log($scope.device.Serial);
console.log($scope.device.ChildName);
console.log(data);
$http.post('http://141.135.5.117:3500/device/register', data, { headers: headers })
.then(function(response){
console.log(response);
console.log(headers);
});
}`
Settings.html ( Note: this is a view in ng-view)
<form role="form" class='userForm'>
<label for="addDevice">Add Device</label>
<input type="text" class="form-control" id="deviceserial" placeholder="Enter serial number" ng-model="$scope.device.Serial">
<input type="text" class="form-control" id="Devicechildname" placeholder="Enter baby name" ng-model="$scope.device.ChildName">
<button type="submit" class="btn btn-success btn-block" ng-click="addDevice()">Add Device</button>
<p>{{$scope.device.Serial}}</p>
</form>
This is the console output
Console output
All the functions are done in one controller.
First Remove $scope from ng-model="$scope.device.Serial"
and define $scope.device = {}; outside $scope.addDevice = function(){
$scope.device = {};
$scope.addDevice = function(){
-- you code here --
}
Working code example
angular.module('inputExample', [])
.controller('ExampleController', ['$scope','$http', function($scope,$http) {
$scope.val = '1';
$scope.device = {};
$scope.addDevice = function(){
var data = {
'Name' : $scope.device.ChildName,
'Serial' : $scope.device.Serial
};
console.log($scope.device.Serial);
console.log($scope.device.ChildName);
console.log(data);
$http.post('http://141.135.5.117:3500/device/register', data)
.then(function(response){
console.log(response);
console.log(headers);
});

I have recently started working on AngularJS 1.6.
I am trying to submit a form programmatically. The reason is I want to validate a few fields (required field validation). I have spent a lot of efforts (probably 3-4 hours) trying to make this work but none of the existing answers on stack overflow or AngularJS docs seems to be working for me today (strange), hence I am posting this as last resort.
Below is my html
<form method="post" id="loginform" name="loginform" ng-submit="loginUser()" novalidate>
<div>
{{message}}
</div>
<div>
<label>User Name</label>
<input type="text" id="txtUserName" ng-model="user.UserName" name="user.UserName" />
</div>
<div>
<label>Password</label>
<input type="text" id="txtPassword" ng-model="user.Password" name="user.Password" />
</div>
<div>
<input type="submit" id="btnLogin" title="Save" name="btnLogin" value="Login" />
</div>
</form>
My angular code
var demoApp = angular.module('demoApp', []);
demoApp.controller("homeController", ["$scope", "$timeout", function ($scope, $timeout) {
$scope.loginUser = function () {
var form = document.getElementById("loginform");
//var form = $scope.loginform; - tried this here...
//var form = $scope["#loginform"]; tried this
//var form = angular.element(event.target); - tried this...
// tried a lot of other combinations as well...
form.attr("method", "post");
form.attr("action", "Home/Index");
form.append("UserName", $scope.user.UserName);
form.append("Password", $scope.user.Password);
form.append("RememberMe", false);
form.submit();
};
}]);
I keep on getting error 'attr' is not a function.
All I need is submit a form using post method, with values. Just before that I am trying to intercept the submit call and check for validations.
I am open to try any other approach as well. Such as changing the input type from submit to button. Putting the input outside the form. I would be more than happy if validations and submit both can happen any which way. I just want it to post back the values after validating on the client side and then the server will take care of the redirect.
Note: I want the form to do a full postback so that I can get it to redirect to another form. (I know I could use Ajax, but some other day, may be!)
1st of all avoid doing var form = document.getElementById("loginform");. Instead of using form.submit you can use the following code. Do it the angular way cheers :D
$scope.loginUser = function () {
if($scope.loginform.$valid){
user.rememberme=false;
$http({
url: 'Home/Index',
method: "POST",
data: user
})
.then(function(response) {
// success
},
function(response) { // optional
// failed
});
}
};
this is a code to validation if validation not complate button is not enable
<form method="post" id="loginform" name="loginform" ng-submit="loginUser()" novalidate>
<div>
{{message}}
</div>
<div>
<label>User Name</label>
<input type="text" id="txtUserName" required ng-model="user.UserName" name="UserName" />
</div>
<div>
<label>Password</label>
<input type="text" id="txtPassword" ng-model="Password" name="user.Password"required />
</div>
<div>
<input type="submit" ng-disabled="myForm.UserName.$invalid || myForm.Password.$invalid" id="btnLogin" title="Save" name="btnLogin" value="Login" />
</div>
</form>
You should use $scope when trying to access the form, something like $scope.loginform. But......
Take a look at ng-messages. Heres an example using ng-messages with your form:
<form id="loginform" name="loginform" ng-submit="loginUser()">
<div>
{{message}}
</div>
<div>
<label>User Name</label>
<input type="text" id="txtUserName" ng-model="user.UserName" name="user.UserName" required/>
<div class="help-block" ng-messages="loginform.txtUserName.$error" ng-show="loginform.txtUserName.$touched">
<p ng-message="required">Username is required.</p>
</div>
</div>
<div>
<label>Password</label>
<input type="text" id="txtPassword" ng-model="user.Password" name="user.Password" required/>
<div class="help-block" ng-messages="loginform.txtPassword.$error" ng-show="loginform.txtPassword.$touched">
<p ng-message="required">Password is required.</p>
</div>
</div>
<div>
<input type="submit" id="btnLogin" title="Save" name="btnLogin" value="Login" ng-click="loginUser()" />
</div>
</form>
Add ngMessages:
var demoApp = angular.module('demoApp', ['ngMessages']);
demoApp.controller("homeController", ["$scope", "$timeout", function ($scope, $timeout) {
$scope.loginUser = function () {
if($scope.loginform.$valid){
//Code to run before submitting (but not validation checks)
} else{
return false;
}
};
}]);
Don't forget to include ngMessages in your app declaration and include the ngMessages.js script file. Note how you can simply use HTML5 validators.
I found the thing I was looking for. In the end I had to create a directive for validating and then submitting. So I am posting it here as a whole answer.
My HTML
<div ng-controller="homeController" ng-init="construct()">
<form method="post" action="Index" role="form" id="loginform" name="loginform" ng-form-commit novalidate class="ng-pristine ng-invalid ng-invalid-required">
<div class="form-group">
<label for="UserName">User ID</label>
<input autocomplete="off" class="form-control ng-valid ng-touched ng-pristine ng-untouched ng-not-empty"
id="UserName" name="UserName" ng-model="user.UserName" type="text" value=""
ng-change="userNameValidation = user.UserName.length == 0">
<span class="field-validation-error text-danger" ng-show="userNameValidation">The User ID field is required.</span>
</div>
<div class="form-group">
<label for="Password">Password</label>
<input autocomplete="off" class="form-control ng-valid ng-touched ng-pristine ng-untouched ng-not-empty"
id="Password" name="Password" ng-model="user.Password" type="password" value=""
ng-change="passwordValidation = user.Password.length == 0">
<span class="field-validation-error text-danger" ng-show="passwordValidation">The Password field is required.</span>
</div>
<div>
<input type="button" id="btnLogin" title="Login" name="btnLogin" value="Login" ng-click="validateUser(loginform)" />
</div>
</form>
</div>
Look for ng-form-commit on the form element. It is the directive that I created.
My Angular code
var demoApp = angular.module('demoApp', []);
demoApp.factory("commonService", function () {
return {
isNullOrEmptyOrUndefined: function (value) {
return !value;
}
};
});
//This is the directive that helps posting the form back...
demoApp.directive("ngFormCommit", [function () {
return {
require: "form",
link: function ($scope, $el, $attr, $form) {
$form.commit = function () {
$el[0].submit();
};
}
};
}]);
demoApp.controller("homeController", ["$scope", "commonService", function ($scope, commonService) {
$scope.construct = function construct() {
$scope.user = { UserName: "", Password: "" };
};
$scope.userNameValidation = false;
$scope.passwordValidation = false;
$scope.isFormValid = false;
$scope.validateUser = function ($form) {
$scope.isFormValid = true;
$scope.userNameValidation = commonService.isNullOrEmptyOrUndefined($scope.user.UserName);
$scope.passwordValidation = commonService.isNullOrEmptyOrUndefined($scope.user.Password);
$scope.isFormValid = !($scope.userNameValidation || $scope.passwordValidation);
if ($scope.isFormValid === true) {
$scope.loginUser($form);
}
};
$scope.loginUser = function ($form) {
$form.commit();
};
}]);
I found the directive here

Html :
I'm using controller as syntax.
<form name="occupantDetailForm" role="form" novalidate class="form-validation">
<div class="form-group form-md-line-input form-md-floating-label no-hint">
<input class="form-control" type="text" name="LastName" ng-model="vm.occupantDetail.lastName" ng-class="{'edited':vm.occupantDetail.lastName}" maxlength="#OccupantDetail.MaxLength" required>
<label>#L("LastName")</label>
</div>
<button type="submit" class="btn btn-primary blue" ng-click="vm.saveOccupantDetail(occupantDetailForm)" ng-disabled="occupantDetailForm.$invalid"><i class="fa fa-save"></i> <span>#L("Save")</span></button>
</form>
JS :
vm.saveOccupantDetail = function (form) {
vm.occupantDetailForm = form;
createOrEditOccupantDetail();//create or edit
vm.occupantDetail = {};
vm.occupantDetailForm.$setPristine();
}
Q : I have tried many ways but it is not working ? When I use the vm.occupantDetailForm.$setUntouched(); then it works fine.But then the problem is Save button is not being disabled.Could you tell me why ? When I use the vm.occupantDetailForm.$setPristine(); only then it is not working at all.Why ? Thanks.
$setPristine only marks your form as $pristine and to actually reset the form you need, set your model to a new object.
A better explanation is given here in the link:
$setPristine not working
Below is some code which might help you:
<div ng-app="myapp">
<div ng-controller="UserCtrl">
<form name="user_form" novalidate>
<input name="name" ng-model="user.name" placeholder="Name" required/>
<button class="button" ng-click="reset()">Reset</button>
</form>
<p>
Pristine: {{user_form.$pristine}}
</p>
</div>
</div>
Controller Code:
var app = angular.module('myapp', []);
function UserCtrl($scope) {
$scope.reset = function() {
$scope.user = {};
$scope.user.name = "";
$scope.user_form.$setPristine();
$scope.user = {};
}
}
A fiddle:
http://jsfiddle.net/p7e1nway/1/
Update:, can you try setting $submitted to false
$scope.occupantDetailForm.$setPristine();
$scope.occupantDetailForm.$setUntouched();
$scope.occupantDetailForm.$submitted = false;
How to add value to ng-model in angularjs. my html is:
<textarea rows="5" ng-model="comment.comment_text"></textarea>
<input type="hidden" ng-model="comment.task_id" value="{{task.id}}">
<input type="hidden" ng-model="comment.user_id" value="{{profile.id}}">
<button type="submit" class="btn btn-success" ng-click="create(comment)">Send</button>
and angular controller:
$scope.create = function(comment) {
console.log(comment);
};
when click on button show result in console:
{comment_text: "test"}
BUT I want to show like this:
{comment_text: "test", user_id:1 ,task_id:53}
On your controller's constructor you should definitely instantiate the initial value of your 'comment' variable using:
$scope.comment = $scope.comment || {
user_id: 'amcpanaligan',
comment_text: 'sample'
//// other object property declaration goes here...
};
value={{someValue}} does not make sense.
You should use only ng-model for text input hidden
function Ctrl($scope) {
$scope.task = {
id: 1
}
$scope.create = function(comment) {
comment.taskId = $scope.task.id;
console.log(comment);
};
}
<div ng-app="">
<div ng-controller="Ctrl">
<textarea rows="5" ng-model="comment.comment_text"></textarea>
<input type="hidden" ng-model="task.id">
<button type="submit" class="btn btn-success" ng-click="create(comment)">Send</button>
</div>
</div>
