signUpview.html
<div class="col-md-6">
<label for="datepicker" class="col-lg-5 form-label">Date Of Birth:</label>
<div class="col-lg-7">
<input type="text" class="form-control dateBirth" ng-model="user.dob" id="datepicker" name="datepicker" datepicker placeholder="Date Of Birth" required/>

datepickerDirective.js
app.directive('datepicker', function() {
var linker = function(scope, element, attrs) {
element.datepicker().on('changeDate', function(){
console.log(scope);
$(".datepicker").hide();
});
}
return {
require: 'ngModel',
restrict: 'A',
link: linker
}
});
you can use ngModel.$setViewValue update the model property
app.directive('datepicker', function() {
var linker = function(scope, element, attrs,ngModelCtrl) {
element.datepicker().on('changeDate', function(){
console.log(scope);
ngModelCtrl.$setViewValue(value);//value is datepicker selected date;
$(".datepicker").hide();
});
}
return {
require: 'ngModel',
restrict: 'A',
link: linker
}
});

I want to create a custom form validation, using AngularJS. That form should have input and select elements. The form should be valid, when either imputs are empty or both filled with some values. Here is the view:
<form name="recipientsForm" novalidate>
<md-input-container>
<label>Name</label>
<input name="name" type="text" ng-model="relationship.name" value="" empty-or-both-filled="relationship.relationshipType">
<div ng-messages="recipientsForm.name.$error">
<div ng-message="emptyOrBothFilled">Enter name.</div>
</div>
</md-input-container>
<md-input-container>
<md-select name="type" placeholder="Select your relation... " ng-model="relationship.relationshipType" empty-or-both-filled="relationship.name">
<md-option ng-repeat="type in relationshipTypes" value="{{type.relationshipType}}">
{{type.name}}
</md-option>
</md-select>
<div ng-messages="recipientsForm.type.$error">
<div ng-message="emptyOrBothFilled">Pick relationship.</div>
</div>
</md-input-container>
</form>
And here is the directive:
(function () {
'use strict';
angular
.module('app')
.directive('emptyOrBothFilled', [emptyOrBothFilled]);
function emptyOrBothFilled() {
return {
restrict: 'A',
required: 'ngModel',
scope: {
targetNgModel: '=emptyOrBothFilled'
},
link: function($scope, element, attrs, ngModel) {
ngModel.$validators.emptyOrBothFilled = function(val) {
var isValueEmpty = !val;
var isTargetEmpty = !$scope.targetNgModel;
return (isTargetEmpty && isValueEmpty) || (!isTargetEmpty && !isValueEmpty);
}
$scope.$watch('targetNgModel', function() {
ngModel.$validate();
})
}
}
}
})();
Prompt, please, why do I get this error:
TypeError: Cannot read property '$validators' of undefined
at link (http://localhost:3000/app/shared/directives/EmptyOrBothFilled.js:17:24)
It should be
require: 'ngModel',
not
required: 'ngModel',
in the directive specification.
I need to bind inputs of type 'number' with a different models which are strings. I've managed to bind them using a directive like:
app.directive('input', function () {
return {
restrict: 'E',
require: 'ngModel',
priority:999999,
link: function (scope, elem, attrs, ctrl) {
//Check del tipo input
if (attrs.type.toLowerCase() !== 'number')
{
return;
}
//Paso a numero el valor a colocar
ctrl.$formatters.push(function (value)
{
return value ? parseFloat(value) : null;
});
}
};
});
And the HTML is like this:
<input class="form-control" type="number" ng-model="scopeValue" />
Up to here, there is no problem with binding. But, when I write a ng-repeat and ng-switch combined this directive is not executed. Sample code:
<div ng-repeat="attribute in attributes" ng-switch on="attribute.type">
<div class="input-group">
<span class="input-group-addon" id="basic-addon2">{{attribute.label}}</span>
<input class="form-control" ng-switch-when="text" ng-model="attribute.value" type="text" name="{{attribute.label}}" value="{{attribute.value}}">
<input class="form-control" ng-switch-when="number" ng-model="attribute.value" type="number" name="{{attribute.label}}" value="{{attribute.value}}">
</div>
</div>
Here the directive link code is never thrown and the inputs with number are never completed. As far as I know, the directive checks all the inputs and has the ngModel dependence. Why is it never executed?
I'm trying to use the angular date time picker. The problem is that I'm loading the data from the model, the picker doesn't seem to bind the value.
If i just set the value manually to a date, it works, but when it's loaded from the model, it doesn't set the picker to the correct value.

I'm using the http://tarruda.github.com/bootstrap-datetimepicker/assets/js/bootstrap-datetimepicker.min.js datetimepicker for angular.
angular:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.date = '01/02/1983 01:02:03';
});
app.directive('datetimez', function() {
return {
restrict: 'A',
require : 'ngModel',
link: function(scope, element, attrs, ngModelCtrl) {
element.datetimepicker({
dateFormat:'dd/MM/yyyy',
timeFormat: 'hh:mm:ss',
}).on('changeDate', function(e) {
ngModelCtrl.$setViewValue(e.date);
scope.$apply();
});
}
};
});
HTML:
<div class="container container-fluid" ng-controller="MainCtrl">
2+2={{2+2}}, var1={{var1}}
<form class="form-horizontal" novalidate name="form" ng-submit="submit()">
<div class="well">
<div id="date" class="input-append" datetimez ng-model="var1">
<input data-format="dd/MM/yyyy hh:mm:ss" type="text" ng-value="date"></input>
<span class="add-on">
<i data-time-icon="icon-time" data-date-icon="icon-calendar"></i>
</span>
</div>
</div>
It's because you are using a string and not a date object:
app.controller('MainCtrl', function($scope) {
var date = new Date(1983, 1, 2, 1, 2);
$scope.date = date;
});

I recommend going with MomentJS for shorthand.
I have directive like this:
.directive('validRegex', function() {
return {
restrict: 'A',
require: 'ngModel',
link: function (scope, element, attrs, ngModel) {
ngModel.$parsers.unshift(function(viewValue) {
console.log(viewValue);
try {
var regex = new RegExp(viewValue);
ngModel.$setValidity('notRegex', true);
return viewValue;
} catch(e) {
ngModel.$setValidity('notRegex', false);
return undefined;
}
});
}
};
})
and I use it like:
<div class="col-sm-7">
<input class="form-control" valid-regex id="search-text" type="text" ng-model="selectedSearchText"/>
<span ng-show="selectedSearchText.$error.notRegex" class="form-error">
Invalid Regular Expression
<span class="icon-attention app_icon"></span>
</span>
</div>
<p>{{selectedSearchText}}</p>
If regex is invalid the the text don't show up as expected but no error message. I've search SO but didn't find a fix.
You have to enclose the input field with in a form as follows
<form name="form">
<div class="col-sm-7">
<input class="form-control" valid-regex id="search-text" type="text" ng-model="selectedSearchText" name="selectedSearchText"/>
<span ng-show="form.selectedSearchText.$error" class="form-error">
Invalid Regular Expression
<span class="icon-attention app_icon"></span>
</span>
</div>
<p>{{selectedSearchText}}</p>
</form>
i am using datepicker and want to bind its value i wrote custom directive for it but know why its not binding value .

datepickerDirective.js
app.directive('datepicker', function() {
var linker = function(scope, element, attrs, ngModelCtrl) {
element.datepicker().on('changeDate', function(value){
var dateStrToSend = value.date.getFullYear() + '/' + (value.date.getMonth() + 1) + '/' + value.date.getDate();
ngModelCtrl.$setViewValue(dateStrToSend);
$(".datepicker").hide();
});
}
return {
require: 'ngModel',

I think you aren't in a digest cycle. Try $apply
element.datepicker().on('changeDate', function(value){
var dateStrToSend = value.date.getFullYear() + '/' + (value.date.getMonth() + 1) + '/' + value.date.getDate();
scope.$apply(function () {
ngModelCtrl.$setViewValue(dateStrToSend);
});
$(".datepicker").hide();
});
