ui-date directive

This directive allows you to add a date-picker to your form elements.

Requirements

• AngularJS
• JQuery
• JQueryUI
• Date.toISOString() (requires polyfill for ≤IE8)

Testing

We use karma and jshint to ensure the quality of the code. The easiest way to run these checks is to use grunt:

npm install -g grunt-cli npm install bower install grunt

The karma task will try to open Chrome as a browser in which to run the tests. Make sure this is available or change the configuration in test\test.config.js

Usage

We use bower for dependency management. Add

dependencies: {
    "angular-ui-date": "latest"
}

To your bower.json file. Then run

bower install

This will copy the ui-date files into your components folder, along with its dependencies.

Add the css:

<link rel="stylesheet" href="components/jquery-ui/themes/smoothness/jquery-ui.css"/>

Load the script files in your application:

<script type="text/javascript" src="components/jquery/jquery.js"></script>
<script type="text/javascript" src="components/jquery-ui/ui/jquery-ui.js"></script>
<script type="text/javascript" src="components/angular/angular.js"></script>
<script type="text/javascript" src="components/angular-ui-date/src/date.js"></script>

Add the date module as a dependency to your application module:

var myAppModule = angular.module('MyApp', ['ui.date'])

Apply the directive to your form elements:

<input ui-date>

Options

All the jQueryUI DatePicker options can be passed through the directive.

myAppModule.controller('MyController', function($scope) {
	$scope.dateOptions = {
		changeYear: true,
		changeMonth: true,
		yearRange: '1900:-0'
	};
});

<input ui-date="dateOptions" name="DateOfBirth">

Static Inline Picker

If you want a static picker then simply apply the directive to a div rather than an input element.

<div ui-date="dateOptions" name="DateOfBirth"></div>

Working with ng-model

The ui-date directive plays nicely with ng-model and validation directives such as ng-required.

If you add the ng-model directive to same the element as ui-date then the picked date is automatically synchronized with the model value.

The ui-date directive stores and expects the model value to be a standard javascript Date object.

ui-date-format directive

The ui-date directive only works with Date objects. If you want to pass date strings to and from the date directive via ng-model then you must use the ui-date-format directive. This directive specifies the format of the date string that will be expected in the ng-model. The format string syntax is that defined by the JQueryUI Date picker. For example

<input ui-date ui-date-format="DD, d MM, yy" ng-model="myDate">

Now you can set myDate in the controller.

$scope.myDate = "Thursday, 11 October, 2012";

ng-required directive

If you apply the required directive to element then the form element is invalid until a date is picked.

Note: Remember that the ng-required directive must be explictly set, i.e. to "true". This is especially true on divs:

<div ui-date="dateOptions" name="DateOfBirth" ng-required="true"></div>
