How can one input be the same value as another input via angularjs? I know how to do this via jquery but not in angularjs. Here is my code:
<body ng-app="peopleApp">
<div ng-controller="myController">
<input class="form-control input-form" ng-model="input.user_code" name="user_code" type="text" maxlength="4" minlength="4" required>
<input class="form-control input-form" ng-model="input.username" name="username" type="text" required>
</div>
</body>
<script type="text/javascript">
var peopleApp = angular.module('peopleApp', []);
peopleApp.controller('myController', function(){
$scope.input = {
'username': $scope.input.user_code
}
});
</script>
So basically what I want is the first input element to be the same value as the second input element
use ng-blur or ng-change
<body ng-app="peopleApp">
<div ng-controller="myController">
<input class="form-control input-form" ng-blur="input.username = input.user_code" ng-model="input.user_code" name="user_code" type="text" maxlength="4" minlength="4" required>
<input class="form-control input-form" ng-model="input.username" name="username" type="text" required>
</div>
</body>
The answer above works, but if you want it to update in real time, just use the same model:
<input class="form-control input-form" ng-model="input.user_code" name="user_code" type="text" maxlength="4" minlength="4" required>
<input class="form-control input-form" ng-model="input.user_code" name="username" type="text" required>
When you change one of the two, the other will update as well. You can also use this as any other tag. For example, this will show what you type on the <p> tag:
<input class="form-control input-form" ng-model="input.user_code" name="user_code" type="text" maxlength="4" minlength="4" required>
<p> {{ input.user_code }} </p>

I am building my first angular app and looking to post my form into my JSON data.
This is my form:
<span ng-show="show">
<form name="inputForm" class="form-group" ng-controller="FormController as autoctrl" ng-submit="inputForm.$valid && autoctrl.addGegevens(gegeven)" novalidate>
<br>
<p> Type: <input type="text" name="type" ng-model="type" style="margin-left:52px; padding-left:5px; width:165px;" minlength="2" maxlength="10" required /></p>
<p>Bouwjaar: <input type="number" name="bouwjaar" ng-model="bouwjaar" style="margin-left:22px; padding-left:5px; width:165px;" minlength="4" maxlength="4" required /></p>
<p>Km: <input type="number" name="km" ng-model="km" style="margin-left:60px; padding-left:5px; width:165px;" minlength="2" maxlength="6" required /></p>
<p>Brandstof: <input id="select" name="brandstof" ng-model="brandstof" style="margin-left:20px; padding-left:5px;" minlength="3" maxlength="7" required/></p>
<p>Kenteken: <input type="text" name="kenteken" ng-model="kenteken" style="margin-left:22px; padding-left:5px; width:165px;" minlength="6" maxlength="9" required /></p>
<p>Datum: <input type="text" name="datum" ng-model="datum" style="margin-left:40px; padding-left:5px; width:165px;" minlength="3" maxlength="11" required /></p>
<p>checked: <input type="checkbox" name="checked" ng-model="checked" style="margin-left:28px;" required /></p>
<br>
<button class="btn btn-primary" type="submit" value="submit">Toevoegen</button>
<div>{{inputForm.$valid}}</div>
</form>
</span>
And this is my app.js:
(function(){
var volkswagenApp = angular.module('volkswagenapp',[]);
volkswagenApp.controller('VolkswagenCtrl', [ '$http' , function($http){
var vw = this;
vw.gegevens = [];
$http.get('autos.json').success(function(data){
vw.gegevens = data;
});
}]);
volkswagenApp.controller('FormController',function(){
this.gegevens={};
/* this.addGegevens = function(gegeven) {
gegeven.gegevens.push(this.gegeven);
this.gegevens={};
}*/
this.addGegevens = function(gegeven){
this.gegevens.datum = Date.now();
vw.gegevens.push(this.gegeven);
this.gegeven = {};
}
});
})();
Can somebody tell me where I am going wrong? I did the same steps as they do on codeschool.
Since you are using controllerAs you need to add the controller object to all the variables in ng-model
Example:
<input name="type" ng-model="type">
Should be:
<input name="type" ng-model="autoctrl.type">
However you can make it simpler to post a single object by making all the ng-model's properties of the same parent
<input name="type" ng-model="autoctrl.myFormModel.type">
Then when you are ready to post you simply send myFormModel
$http.post(url, this.myFormModel).then(....
Note that you should store a reference to this so you can use that reference inside any callbacks. I see you using vm but it is not defined anywhere inside FormController

I have a form where I am checking for incorrect input with ng-pattern and showing error message on incorrect entry.
I want the form submit to be disabled when user tries to submit the form with incorrect values with out using ng-disabled option because required option of html is checking for empty text boxes on clicking submit button. How do I achieve this? Do I have to go for custom directive?

This link will help explain how to disable a submit button until a form is valid.
You will need to add ng-disabled="FORMNAME.$invalid" attribute to your <input type="Submit" class="form-control btn btn-success" value="Submit" /> element (replace FORMNAME with the model name for your form data).
That should do it. Comment below with any other issues.
You appear to want all fields to be required, but that when users think they're ready for form submission, they are kindly notified if they have forgotten any required fields.
Normally this is achieved with ng-submit and something like:
<span ng-if="myForm.$submitted && myForm.formField.$error.required">Please enter information for 'formField'</span>
Here the users are allowed to click submit, but are then shown a message about the required field.
However, this is only works when no action (action="RegistrationServlet.do") is specified on the form. In your case, you need to intercept form submission. One way to do that is to capture the mouse click event to disable and update the form if there are form errors:
app.controller('MainCtrl', function($scope) {
$scope.submit = function($event) {
if ($scope.myForm.$invalid) {
$scope.myForm.$submitted = true;
$event.preventDefault();
}
}
<form name="myForm" action="action.do" method="Post" novalidate>
<input type="text" name="formField" ng-model="formField" required><br>
<span class="error" ng-if="myForm.$submitted && myForm.formField.$error.required">Please fill field above<br></span>
<button type="submit" ng-click="submit($event)">Submit</button>
</form>
See the plnkr here
What you need to do is using ng-Submit so that you can do validation when user click submit.
var app = angular.module('myApp',[]);
app.controller('numOnlyRegex',function($scope){
$scope.TestSubmit = function()
{
if($scope.myForm.$valid)
{
//normal submit
}
}
});

I have a form and I want to disable form submit when input fields are empty. I want to show an error when user clicks on submit button where the input fields are empty. I don't want to show error by default.

You can define constants
angular.module('test').constant('regEx', {
numOnlyRegex: '/^\d{1,6}$/',
firstNameAndLastName: '/^[a-zA-Z]{3,20}$/',
password: '/^[a-zA-Z]{3,5}$/',
mobile: '/^[7-9][0-9]{1,9}$/',
email: '/\S+#\S+\.\S+/'
})
This constants can be injected into controllers/services/directives
.controller('TestCtrl', ['$scope','regEx', function ($scope,regEx) {
$scope.numOnlyRegex = regEx.numOnlyRegex;
}])
EDIT
With constants you can create static variables that can be used in other controllers/services/directives.
In your example you can put all of your regular Expression in one constant object and use this in your whole application.
And then you can use it like this
ng-pattern expects a regex expression.
From Angular's documentation about ng-pattern:
Sets pattern validation error key if the value does not match the
RegExp pattern expression. Expected value is /regexp/ for inline
patterns or regexp for patterns defined as scope expressions.
In other words, you could create a RegExp in the controller:
$scope.numOnly= new RegExp(regEx.numOnlyRegex);
and use it:
<input ng-model="foo" ng-pattern="numOnly">
I would like to set invalid with angular when firstname is equals to lastname and change the color using styles to red.

$scope.$watch("app.lastName", function(newVal, oldVal) {
if (!!$scope.app.lastName && !!newVal)
if (angular.lowercase($scope.app.firstName) === angular.lowercase(newVal)) {
debugger;
$scope.form.inputLastName.$setValidity("sameName", false);
}
});
}
<body ng-app>
<div class="container" ng-controller="RegoController">

</div>
<div class="form-group">
<label for="inputLastName">Last Name</label>
<input id="inputLastName" class="form-control" type="text" ng-model="app.lastName" placeholder="Enter your last name" required ng-minlength="3" ng-maxlength="20" />

The problem is that you are trying to select a form input that has no name; thus making it unable to find the field you are trying to invalidate. Here is a working example:
JSBIN: http://jsbin.com/yozanado/1/
Input field with name:
<input id="inputLastName" name="lastName" class="form-control" type="text" ng-model="app.lastName" placeholder="Enter your last name" required ng-minlength="3" ng-maxlength="20" />
Javascript:
$scope.form.lastName.$setValidity("sameName", false);
AngularJS form validation relies on the name of the form and the name of the fields to find the validation models on scope.
For example, if your HTML is:
<form name="form">
<input name="firstName" ng-model="firstName" />
</form>
You will be able to access the validation $error property on scope using the name attributes:
$scope.form.firstName.$error.sameName
To fix the issues you're having, add a name attribute to your input fields.
