Ionic apps are made of high-level building blocks called Components, which allow you to quickly construct the UI for your app.
Ionic comes stock with a number of components, including cards, lists, and tabs. Action Sheets display a set of options with the ability to confirm or cancel an action. Cards are a great way to display an important piece of content, and can contain images, buttons, text, and more. Floating action buttons are circular buttons that perform a primary action on a screen.
Infinite scroll allows you to load new data as the user scrolls through your app. Lists can display rows of information, such as a contact list, playlist, or menu. Menus are a common navigation pattern. They can be permanently on-screen, or revealed when needed. Alerts are a great way to offer the user the ability to choose a specific action or list of actions. Badges are a small component that typically communicate a numerical value to the user.
Buttons let your users take action. They're an essential way to interact with and navigate through an app. Checkboxes can be used to let the user know they need to make a binary decision. Chips are a compact way to display data or actions. Content is the quintessential way to interact with and navigate through an app.
Beautifully designed icons for use in web, iOS, Android, and desktop apps. The grid is a powerful mobile-first system for building custom layouts. Inputs provides a way for users to enter data in your app. Items are an all-purpose UI container that can be used as part of a list. Navigation is how users move between different pages in your app. Modals slide in and off screen to display a temporary UI and are often used for login or sign-up pages.
Popover provides an easy way to present information or options without changing contexts. Progress indicators visualize the progression of an operation or activity. Radio inputs allow you to present a set of exclusive options. Refresher provides pull-to-refresh functionality on a content component.
Searchbar is used to search or filter items, usually from a toolbar. Reorder lets users drag and drop to reorder a list of items.
Ionic - Forms
Routing allows navigation based on the current path. Segments provide a set of exclusive buttons that can be used as a filter or view switcher. Select is similar to the native HTML select, with a few improvements to sorting and selecting. Slides make it easy to create complex UI such as galleries, tutorials, and page-based layouts.
Tabs enable tabbed navigation, a standard navigation pattern in modern apps. Toast is used to show a notification over the top of an app's content. It can be temporary or dismissable. Toggles are an input for binary options, often used for options and switches.
Toolbars are used to house information and actions relating to your app. Contribute Updated You may be familiar with using [ ngModel ] to set up two-way data binding between inputs in your templates, and variables in your class definition. For example you might have an input field like this:.
In this tutorial, we are going to look at a more complex, but also more powerful, way to set up forms in an Ionic application. We will be building a multi stage sign up form as an example. The method we will use makes it easier to manage forms with many fields, and it also allows us to more easily validate data that is entered, this includes:.
We will be using FormBuilder to create our forms and Validatorswhich are used in conjunction with FormBuilderto validate the input. It can easily be circumvented, so if you are sending this data off to a server you must also validate and sanitize the input on the server side. When building forms in Angular it is important to understand what a FormControl is and what a FormGroup is.
A FormControl is tied to an input field, it has a value i. A FormGroup is a collection of FormControls. We can also create and manage multiple FormControls at once in a single FormGrouplike this:. We can use another service called FormBuilder to make the process of creating a FormGroup a little easier, and it would look like this:.
We use the formBuilder. The first value is required although it can just be an empty string and is the default value of the FormControl. The second value is optional, and is a validation function that is used to check the value of the FormControl.
The third value is also optional, and is basically the same as the second except that it is for asynchronous validation. This means if you need to perform a check that is not instant like checking if a username already exists on a server then you can use an asynchronous validation function. The default Validators include:. Most of these are pretty obvious. The required validator will ensure that a value is entered, minLength and maxLength ensure that the length of the input is of a certain length, and pattern uses a regex pattern to validate the input.
So an actual FormGroup created by FormBuilder might look like this:. For the first two controls we are supplying three different validators. We want the input to be shorter than 30 characters, only contain letters and spaces, and it is also a required field. To use multiple Validators we can use the Validators. The last control uses a custom validator to validate the age control we will be covering how to do that later. This should give you some background, and we are about to go through a practical example in Ionic now, but if you would like some more background information on forms in Angular, I highly recommend these two posts:.
Before you go through this tutorial, you should have at least a basic understanding of Ionic concepts. You must also already have Ionic set up on your machine.
When using ngModel to handle data we are just using the default FormsModulebut the methods we will be using in this tutorial involve the use of the ReactiveFormsModule. Therefore, we need to make sure that we include the ReactiveFormsModule wherever we want to make use of that functionality. To set up our multi page form we are going to use the Slides component.
We will set up two slides, and add a method to go backwards and forwards between the slides as well as having the ability to just swipe between the two. We are importing FormBuilderFormGroupand Validatorsall of which we have just been discussing, and we set up member variables for the two forms we will be creating: slideOneForm and slideTwoForm.
Modify the constructor in home. Apart from that, everything else is the same. Now both our forms are set up, but they do not currently have any validation. Some of the validations we want to do are covered by Angular by default, so we will focus on those first.
We will be creating our own custom validators for those now. This is the simpler of the two validators. We simply pass in the current value through a reference to the FormControl.Get started building by installing Ionic or following our First App Tutorial to learn the main concepts.
It's easy to learn, and integrates with other libraries or frameworks, such as AngularReactor Vue. Alternatively, it can be used standalone without any frontend framework using a simple script include. Ionic is the only mobile app stack that enables web developers to build apps for all major app stores and the mobile web from a single codebase. And with Adaptive StylingIonic apps look and feel at home on every device. Ionic is built to perform and behave great on the latest mobile devices with best practices like efficient hardware accelerated transitions, and touch-optimized gestures.
Ionic is designed to work and display beautifully on all current mobile devices and platforms. With ready-made components, typography, and a gorgeous yet extensible base theme that adapts to each platform, you'll be building in style. Ionic emulates native app UI guidelines and uses native SDKs, bringing the UI standards and device features of native apps together with the full power and flexibility of the open web.
Because of this, Ionic components have a stable API, and aren't at the whim of a single platform vendor. Clean, simple, and functional. Ionic Framework is designed to work and display beautifully out-of-the-box across all platforms. Start with pre-designed components, typography, interactive paradigms, and a gorgeous yet extensible base theme.
Ionic Framework is built with simplicity in mind, so that creating Ionic apps is enjoyable, easy to learn, and accessible to just about anyone with web development skills.
While past releases of Ionic were tightly coupled to Angular, version 4. Ionic can be used in most frontend frameworks with success, including React and Vue, though some frameworks need a shim for full Web Component support. One of the main goals with moving Ionic Framework to Web Components was to remove any hard requirement on a single framework to host the components. This made it possible for the core components to work standalone in a web page with just a script tag.
While working with frameworks can be great for larger teams and larger apps, it is now possible to use Ionic as a standalone library in a single page even in a context like WordPress.
Angular has always been at the center of what makes Ionic great. Ionic now has official support for the popular React library. Ionic React lets React developers use their existing web skills to build apps that target iOS, Android, the web, and the desktop. Support for other frameworks are expected in a future release.
Currently official bindings for Vue are in development, though some components just work out of the box in those frameworks. In addition to installing and updating Ionic, the CLI comes with a built-in development server, build and debugging tools, and much more. If you are an Ionic Appflow member, the CLI can be used to perform cloud builds and deployments, and administer your account.
To help build, deploy, and manage Ionic apps throughout their lifecycle, we offer a commercial service for production apps called Ionic Appflowwhich is separate from the open source Framework. Appflow helps developers and teams compile native app builds and deploy live code updates to Ionic apps from a centralized dashboard. Optional paid upgrades are available for more advanced capabilities like publishing directly to app stores, workflow automation, single sign-on SSO and access to connected services and integrations.
Ionic Framework is actively developed and maintained full-time by a core team, and its ecosystem is guided by an international community of developers and contributors fueling its growth and adoption.Ionic 2 Inputs Inputs are an important component of any framework, Inputs are used to collect and handle the user data. Ionic 2 provides the rich inputs that can be used easily.
Here in this tutorial we are going to explain how you can create form inputs in Ionic 2. You can also use our online editor to run the online demo.
To create fixed inline lables fixed attribute is used. Fixed inline lables are fixed to its position although you enter some text in the text input field, you can also add the placeholder for input field.
Here in an example of the fixed inline label. To create floating label add floating attribute to ion-label. Here in an example of the floating inline label.
An ion-label without any attribute is inline, Inline label does not hide when you enter text. You can also add placeholder in the text field. Here is an example of inline label. To create stacked labels add stacked attribute to ion-label. Stacked labels always appear above the input field.

A class decorated with Directive to attached metadata is called a directive. There are three types of directive supported by Angular, namely. Directive extends the HTML language through directives to make page templates more dynamic and customization.
Ionic by default we have lots of directives, eg ngFor, ngIf. Angular defines directives as components without views. In fact, a component is a directive with an associated template view.

For event detection on DOM, will map event name to the class methods.
For example, mouseenter event will trigger a call to the onMouseEnter methods in the directive class. You modify the behavior on the keyboard using el. Entering the special character will trigger e. The Input decorator is used to declare that you will bring a variable from the template.
