I need to add class to input parent if input is not empty or focus because I want to change label position.
<div class="input-field">
<input type="email" name="email" ng-model="email" required />
<label for="email">Email</label>
</div>
I can do this:
<div class="input-field" ng-class="{ active: signIn.email.$viewValue.length > 0 || isFocus }">
<input type="email" name="email" ng-model="email" ng-focus="isFocus=true" ng-blur="isFocus=false" required />
<label for="email">Email</label>
</div>
But I have many inputs and my code will be very large and ugly.
How can I do it better?
Thank you.
Go with attribute directive where you can have logic which class you need to add to input-filed.
angular.directive('myClass', function() {
return {
restrict: 'A',
link: function (scope, element,attr) {
// your logic
}
};
or
$scope.myClass = "";
<div class="input-field" ng-class="myClass" />
angularjs : setting class attribute in a directive template
You can use a scope variable for this.
myApp = angular.module("myApp",[]).controller("myController",['$scope',function($scope){
var someCondition = 2 > 1;
$scope.myClass = {
active : someCondition ? "active" : "not-so-active"
}
}]);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myController">
<div class="input-field" ng-class="{{myClass}}">
<input type="email" name="email" ng-model="email" ng-focus="focus=true" ng-blur="focus=false" required />
<label for="email">Email</label>
</div>

I am trying to call a function when the check box is checked and set the field values accordingly. The checkbox and the address fields are like below
<div class="form-check">
<input class="form-check-input position-static" type="checkbox" id="SameAsShippingAddress" value="SameAsShippingAddress" data-bind="checked: sameAsShippingAddress" />
<label>Check this box if Shipping Address and Billing Address are the same.</label>
</div>
<div class="row">
<div class="col-md-6">
<h4>Shipping Address:</h4>
<div class="form-group required">
<label for="EmailCompetitor" class="control-label">Email:</label>
<input type="email" maxlength="150" id="EmailCompetitor" name="EmailCompetitor" class="form-control" data-bind="value: emailCompetitor" required />
</div>
<div class="form-group required">
<label for="FirstNameCompetitor" class="control-label">First Name:</label>
<input type="text" maxlength="150" id="FirstNameCompetitor" name="FirstNameCompetitor" class="form-control" data-bind="value: firstNameCompetitor" required />
</div>
</div>
<div class="col-md-6">
<h4>Billing Address:</h4>
<div class="form-group required">
<label for="EmailCompetitor_Billing" class="control-label">Email:</label>
<input type="email" maxlength="150" id="EmailCompetitor_Billing" name="EmailCompetitor_Billing" class="form-control" data-bind="value: emailCompetitor_Billing" required />

I want the check box boolean value captured seperately as well as when check box is checked it needs to call the function. So in js I have like
var orderRequestFormViewModel = function () {
var self = this;
self.currentPage = ko.observable(1);
self.referringPage = ko.observable();
...............
self.sameAsShippingAddress = ko.observable().extend({ required: false });
..........
self.sameAsShippingAddress = function () {
if (this.checked) {
$("#EmailCompetitor_Billing").val($("#EmailCompetitor").val());
$("#FirstNameCompetitor_Billing").val($("#FirstNameCompetitor").val());
} else {
$("#EmailCompetitor_Billing").val("");
$("#FirstNameCompetitor_Billing").val("");
}
}
But when the checkbox is checked/unchecked this function is not being called at all
I tried put the breakpoint but the function is not being it. New to this JS world, any help is greatly appreciated
Hey I made you a little snippet to show you that it works perfectly fine when using an observable and checked binding, when checkbox is checked, it is "true" if not it´s "false"
To make custom stuff like setting .val() of other input just use a computed function, it will be called whenever isChecked changes
var model = function () {
var self = this;
self.isChecked = ko.observable(false);
self.doStuffWhenChecked = ko.computed(function(){
if(self.isChecked()){
$('#textinput').val("whatever");
}else{
$('#textinput').val("");
}
},this);
}
var vm = new model();
ko.applyBindings(vm);

I Have input and I use a custom directive to display the input error with use of ng-messages. And I want to use attribute for showing the error, not ng-message.
Here is my Code
<md-input-container class="md-block" flex-gt-sm>
<label>Enter Your Message</label>
<input required md-no-asterisk ng-model="newEmployee.message" type="text" id="name" name="name" formValidate>
<div ng-messages="Employeeform.message.$error">
<div ng-message="messageValidator">Message is Invalid
</div>
</md-input-container>
Directive :
app.directive('formValidate', function() {
return {
restrict: 'A',
require: 'ngModel',
template: '<p>Name is required</p>',
link: function(scope, element, attr, ctrl) {
function formValidate(ngModelValue) {
if ([A - z].test(ngModelValue)) {
ctrl.$setValidity('formValidate', false)
} else {
ctrl.$setValidity('formValidate', true),
}
return ngModelValue;
}
ctrl.$parsers.push(formValidate);
}
};
});
Make use of angular-form. Go through this doc https://docs.angularjs.org/guide/forms
Without ng-messages
<div class="form-group" ng-class="{ 'has-error': vm.form.firstname.$touched && vm.form.firstname.$invalid }">
<label class="control-label col-xs-3" for="firstname">First Name</label>
<div class="col-xs-9">
<input class="form-control" name="firstname" id="firstname" ng-model="vm.firstname" type="text" ng-change = "vm.resetValidationErrors('firstname')" required/>
<p ng-show="vm.form.firstname.$error.required && vm.form.firstname.$touched" class="help-block">First name is required.</p>
<p ng-show="vm.form.firstname.$error.firstname && vm.form.firstname.$touched" class="help-block">{{ vm.form.firstname.errorMessage }}</p>
</div>
</div>
when clicked on submit button, it will call function, in that function i am trying to write logic to disable submit button when fields are not valid, here email must be contain #, dot and after dot minimum 2 & maximum 4 alphabet characters. I tried bellow code.
HTML:
<div ng-app="myApp" ng-controller="myCtrl">
<form name="myForm">

1st of all you need to give your form a name here its signupForm .
2nd from there you need to give your input fields names for example here they areusername and email.
Then you can use various angular validation directives to set validation constrains like require , length then you can check for validation error using signupForm.username.$invalid and check various error like signupForm.email.$error.email.
Finally if you want to check if the whole from is valid use signupForm.$invalid
and for number validation use
angular.module('test')
.directive('validNumber', function() {
return {
require: '?ngModel',
link: function(scope, element, attrs, ngModelCtrl) {
if(!ngModelCtrl) {
return;
}
ngModelCtrl.$parsers.push(function(val) {
if (angular.isUndefined(val)) {
val = '';
}
var clean = val.replace( /[^0-9\.]/g, '');
if (val !== clean) {
ngModelCtrl.$setViewValue(clean);
ngModelCtrl.$render();
}
return clean;
});
element.bind('keypress', function(event) {
if(event.keyCode === 32) {
event.preventDefault();
}
});
}
};
});

var app = angular.module('jsbin', []);
app.controller('DemoCtrl', function() {
});

Check This Out.
In order to disable the submit button, you can do something like this:
<form name="myForm">
<input ...>
...
<button type="button" ng-disabled="myForm.$invalid" ng-click="formsubmit();">
Submit
</button>
</form>
Notice that I have put ng-disabled with a condition of myForm being invalid. So, instead of waiting for user to click the button, we are disabling the submit button upfront when form is invalid!
For Email validation, I would suggest you to go with <input type = "email"...> unless you have specific email validation requirements not handled by type = "email"
Here's the updated fiddle which disables the submit button until we put a valid email address.
Edit: Here's an example of how ng-pattern can be used to validate email for given rules (i.e. email must contain #, dot and after dot minimum 2 & maximum 4 alphabet characters)
<input type="text" ng-model="user.email" name="email" required
ng-pattern="/[a-zA-Z0-9_.]+\#[a-zA-Z0-9_]+\.[a-zA-Z]{2,4}$/"/>
Here's the updated fiddle
Also, regex101 for the email validation regex
I would like to dynamically display Person and Address data using label and input value in Summary Section. As the user edits the form fields, a list items with label + value should display in the summary tables. If value has been removed in the form, that associated label and value should be removed from the Summary Section.
I have added client side validation for each input element. I tried to solve this and couldn't figure out what is best way to do it. Any help would be appreciated.
Example:
// the main (app) module
var myApp = angular.module("myApp", []);
// add a controller
myApp.controller("myCtrl", function($scope) {
$scope.vm = {
caller: {
person: {
firstName: '',
lastName: '',
phoneOne: '',
email: ''
},
address: {
lineOne: '',
lineTwo: ''
}
}
};
$scope.save = function() {
console.log($scope.vm);
}
});
// add a directive
myApp.directive('showErrors', function($timeout, $compile) {
return {
restrict: 'A',
require: '^form',
link: function(scope, el, attrs, formCtrl) {
// find the text box element, which has the 'name' attribute
var inputEl = el[0].querySelector("[name]");
// convert the native text box element to an angular element
var inputNgEl = angular.element(inputEl);
// get the name on the text box
var inputName = inputNgEl.attr('name');
// only apply the has-error class after the user leaves the text box
var blurred = false;
inputNgEl.bind('blur', function() {
blurred = true;
el.toggleClass('has-error', formCtrl[inputName].$invalid);
});
scope.$watch(function(scope) {
return formCtrl[inputName].$invalid;
}, function(invalid, scope) {
// we only want to toggle the has-error class after the blur
// event or if the control becomes valid
if (!blurred && invalid) {
return
}
el.toggleClass('has-error', invalid);
});
scope.$on('show-errors-check-validity', function() {
el.toggleClass('has-error', formCtrl[inputName].$invalid);
});
scope.$on('show-errors-reset', function() {
$timeout(function() {
el.removeClass('has-error');
}, 0, false);
});
}
}
});

Im trying to post input data with angular, but I don't know how to grab the data from the input fields.
Here is my HTML:
<div ng-controller="Test">
<div class="container">
<div class="col-sm-9 col-sm-offset-2">
<div class="page-header"><h1>Testar</h1></div>
<form name="userForm" ng-submit="submitForm(userForm.$valid)" novalidate> <!-- novalidate prevents HTML5 validation since we will be validating ourselves -->
<div class="form-group" ng-class="{'has-error' : userForm.name.$invalid && !userForm.name.$pristine, 'has-success' : userForm.name.$valid }">
<label>Name</label>
<input type="text" name="name" class="form-control" ng-model="name" required>
<p ng-show="userForm.name.$invalid && !userForm.name.$pristine" class="help-block">Fel namn</p>
</div>
<div class="form-group" ng-class="{'has-error' : userForm.username.$invalid && !userForm.username.$pristine, 'has-success' : userForm.username.$valid && !userForm.username.$pristine}">
<label>Username</label>
<input type="text" name="username" class="form-control" ng-model="user.username" ng-minlength="3" ng-maxlength="8">
<p ng-show="userForm.username.$error.minlength" class="help-block">För kort</p>
<p ng-show="userForm.username.$error.maxlength" class="help-block">För långt</p>
</div>
<div class="form-group" ng-class="{'has-error' : userForm.email.$invalid && !userForm.email.$pristine, 'has-success' : userForm.email.$valid && !userForm.email.$pristine}">
<label>Email</label>
<input type="email" name="email" class="form-control" ng-model="email">
<p ng-show="userForm.email.$invalid && !userForm.email.$pristine" class="help-block">Ange korrekt e-post</p>
</div>
<button type="submit" class="btn btn-primary">Lägg till</button>
</form>
</div>
</div>
</div>
Here is my controller:
as.controller('Test', function($scope, $http, $rootScope)
{
$scope.submitForm = function(isValid) {
if(isValid)
{
$http.post($rootScope.appUrl + '/nao/test', {"data": $scope.userForm})
.success(function(data, status, headers, config) {
console.log(data);
}).error(function(data, status) {
});
}
};
});
A post is made when I hit the button, but the data that Is being sent looks like this:
{"data":{"name":{},"username":{},"email":{}}}
How can I take the data from all the input fields? Should I refer to userForm as I do in the controller?
I suggest to create one more $scope object - at beginning it will be empty:
$scope.form = {};
Every field will be a part of this object:
<input type="text" name="name" class="form-control" ng-model="form.name" required>
After send all fields you will have in object $scope.form.
jsFiddle: http://jsfiddle.net/krzysztof_safjanowski/QjNd6/
you have ng-model variables in scope:
$scope.name
$scope.user.username
$scope.email
you can all of these prefix with user. and then send with ajax $scope.user instead of $scope.userForm
or
try to send object which is copied by: angular.copy($scope.userForm)
You can have a property in your scope, say user. Have all your ng-model values be user.SOMETHING. This way you can easily send the $scope.user holding all the data, as in {data: $scope.user }.
