Series 3: Build an Angular 2 Multi-Step Wizard using UI-Router 1.0 and TypeScript – Part 1

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. My question is how to incorporate form validation within this process, let say for the first form where we have name and the email, how we can we validate it first and restrict moving to the next form if fields are empty etc. So the simple answer is you can just use angularjs validation mechanisms every time you are about to move to the next step.

This works because in the example we switch the content of the entire form every time we change the step on the form. So whenever the user is going to change the step you can call a function to check if the form is valid. For example:. First of all it seems to me like you are starting a new project with forms so I would use the latest version of angularjs at this time it is 1.

Since it is a release candidate they are mostly fixing bugs now and the API should be stable. You can read more about it here. This example is far from complete I just added validation to the email field and changed the behaviour of the 'next' button in order to illustrate checking the validation of the form.

I use angularjs 1. So if you try to click next you can't until you enter a valid email. Then you can click next and it will take you to the next one that's where I stopped with the validation so the rest of the example is meaningless for now. The email is required and it has to be a valid email. Otherwise you get error message if you put an invalid value or try to submit the form. To incorporate form validation into the process you just add the validation rules you want and for every call to the 'next step' button you validate the current version of the form and only advance if it is valid.

Notice I also pass myMultiStepForm. Then in the controller I have a function that checks if the form is valid and only allows a change in state in that case:. Given that the user can use the links on the top to navigate you can also intercept the event of starting to change the state stateChangeStart and see if the previous step is valid and only allow the navigation if the previous step is valid.

Notice I created a value called formSteps that is an array that has the validity of all the steps. That validity is updated in the controller whenever you click next step. You could also do it on change of the field value so that the validity of the form step does not depend on the user clicking next.

Which can be used to hold arbitrary information.With the Angular 2's new forms module, we can build complex forms with even more intuitive syntax. In this article, we will learn about how to build a nested model-driven form with validation using the latest forms module.

If you are new to model-driven forms, please refer to How to Build Model-driven Forms in Angular 2 for a basic rundown. Let's say you have a product with a name and a price in your model. You want to create a form for it that allows a user to add a new product. But what if you want to add multiple products in the same form? How would we loop through each user model and validate it?

Let's take a look at how our app will be setup. We'll have our app folder which contains our components as well as our index. Let's move on to create our app component. We bind myForm to form group directive. The Submit button will be disabled if the form is not valid. Now, let's initialize our form model and create the functions that allow us to add and remove an address. Each form control accepts an array. The first parameter is the default value of the control, the second parameter accepts either a validator or an array of validators, and the third parameter is the async validator.

Please refer to Angular official documentation for details. In our example, we'll assign a list of validators to the name control, and assign a single validator to the street control. Our form is working fine now. But imagine that you have a huge form which consists of a lot of controls, we might need to consider moving each group of controls to a seperate component to keep our code neat. With the new forms module, we can use formArray to create a list of controls.

We can seperate each group of controls to a new component and the validation is still working fine. Like this article? Follow jecelynyeen on Twitter. Table of Contents What is a Nested Form?

This angular tutorial help to create beautiful multi step forms wizards using angular js and bootstrap.

I am using angularjs multi-steps from library. This is very wounder full angular directive based on angular wizards library. You can create very easily multi steps submission form layout using this angular directives. As you have seen multi-steps form many places like shopping cart, questionnaires, employment registration etc.

We will create following files into this angular js multi-step form example. Step 1: We will create index. Step 2: We will define TestApp angular application and created testController into this files. As you can see, I have injected 'angular-steps' library into application and service 'StepsService' into controller.

I have defined submitFinal method into controller which will call at the final step. Step 3: We will define steps into index. Angular steps uses master 'steps' directive that will hold child steps form HTML view. We have created multi steps form using angular-steps directive.

We have also create simple angularjs apps with controller. You can customized this example and add steps notation view above of each step form that let him know you, in which current step your are.

Live Demo. Download Source Code.Forms are the standard method used to collect user inputs on web applications. However, sometimes we may be collecting large amounts that may result in a very large form with several fields.

This can be a pain not just for the user but for the developer as well since they will have to fit these fields into the form in a way that still looks appealing to the user.

Simple Example and Demo of Multistep form Using Angularjs

The solution? Break the form into several sections collecting a certain type of information at each point. We can do this by breaking down the sections steps into individual react components that collect certain inputs. We can then choose which components are rendered at each step by manipulating state. In this tutorial we shall walk through how we can do this as well as sharing functionality across components using an example of a registeration form.

For this tutorial we shall initiate our project using create-react-app which shall take care of configuring our react development environment as well as provide some boilerplate to get us started. To install create-react-app simply run the following script in your terminal:. Now that we have create-react-app installed. The next step is to initialize our application.

To do this run. This will create a sample React application with the development environment fully configured.

The folder structure will look like this. We'll also be using yarn as our default package manager. Yarn is a great alternative to npm as it locks down dependency versions — a feature that was added to recent versions of npm. Yarn is also the default package manager for create-react-app. If you don't have yarn yet, you can find the installation instructions here. Semantic UI React provides several prebuilt components that we can use to speed up our development process.

The framework also supports responsiveness which makes it great for building cross-platform websites. To install it run. To add the custom semantic ui css add the following to the head section of our index. Now that the project is set up let's create a components folder under the src directory in which we'll place our form components. Inside it it create 5 files: Confirmation. Feel free to define empty class components in each of these files that we'll add more functionality to as we work through this tutorial.

Now let's edit app. Delete the boilerplate code added by create-react-app and have the following code instead. We've wrapped the form in a Container component from Semantic UI React which makes it more presentable by centering the text and adding padding. The first component we'll set up is the MainForm component which will be in charge of most of the functionality in our application. Great, let's go through the code we've just added. The biggest step we've taken towards creating our multistep form is using the switch statement which reads the step from state and uses this to select which components are rendered at each step.

The component is initialized with the default value for step in state as 1 and the first section of our form is rendered.

The user can then skip back and forth between steps using the prevStep and nextStep functions respectively. These update the value of step in state so as to allow the user to switch between the rendered components. The handleChange function updates the value of the details provided by the user inside state and like the prevStep and nextStep functions, it will be passed to the child components as props.

This will allow us to pass the functionality implemented for use within the child components as we are about to see in our next step. Now let's create the first section of our form. Inside UserDetails.This technique can be used for large forms that you would like to simplify for your users. We can see this technique used in many places on the web. Places like shopping carts, signup forms, onboarding processes, and more have used the multi-step form to ease users through their online forms.

Here's what we will be building:. We will be using a simple structure for our application. We'll need a layout fileview files for each part of the forma stylesheetand our JavaScript file that will hold all of our Angular code.

Here are the files for our application. Go ahead and create these files and we'll start filling them in as we go. These are what will create each section of our form. Let's start our project by creating the main file that will bring all of our resources together into one place.

We will use our index. We will also be using Bootstrap for quick styling. Notice how we applied our Angular app formApp to the body of our application. We will create our application and routes. For larger applications, you'll want to separate your Angular application, routes, and controllers into their own separate modules, but for our purposes, we'll place them all together as a happy family in.

We also have our routes created. Notice how we can define a urlview file templateUrland controller for each state. It will also have child states denoted by the. The idea behind this is that each nested state will be brought into the main form view as the state of our application changes. We'll demonstrate this in our next section. We now have to create the view for our form and each of its nested states.

Let's start by creating our main form. This will be used as a template file for the rest of our form view files just like our index. All we have to do is include a ui-view in this file so that the nested states know where to inject their view. Notice how this is the second time we've used ui-view in this project. This is what is so great about UI Router; we are able to nest states and views. This provides us a great deal of flexibility when creating our applications.

For more information about UI Router's views, check out their official docs.

I want to create a single big form with angular 2. But I want to create this form with multiple components as the following example shows. App component. When I use the code above it was visible in the browser as i needed but the submit button was not disabled when I delete the text in address component.

But the button was disabled correctly when I delete the text in input box in app component. I can give you an example. All you need to do, is to nest a FormGroup and pass that on to the child.

Let's say your form looks like this, and you want to pass address formgroup to child:. If you do not want to create an actual nested formgroup, you don't need to do that, you can just then pass the parent form to the child, so if your form looks like:.

Using the same example as above, we would only like to show street and zipthe child component stays the same, but the child tag in template would then look like:. Demo of first option, here's the second Demo. More info here about nested model-driven forms. From my experience, this kind of form field composition is hard to make with template-driven forms.

The fields embedded in your address component don't get registered in the form NgForm. There is a way to do that in template driven forms too. You have to make sure though, that each input has a unique name. As a result form validity will also depend on state of controls inside child component. Learn more.
