Join Justin Schwartzenberger for an in-depth discussion in this video Angular forms, part of Angular 2 Essential Training.
- Web applications are usually doing one of two things:…either displaying data, or collecting it.…The way we collect data through web apps is the use…of forms, and more specifically, form elements.…When we build forms in web apps, we architect them…to do a common set of things:…for a way to collect data, for a way to know when user…changes data, for validating data, and for showing…errors to users.…Since forms are a common piece of web app development,…Angular has dedicated code in its framework…to help when working with forms.…
We've covered how you combine data to component template…views, and we've covered how you combine…to DOM events as well.…Angular forms builds upon that, and provides data binding…both in and out.…It also provides indicators out of the box for you to know…when form fields have changed from their original value,…and when they are invalid.…Angular forms provides built-in data validators,…and the ability to create your own.…Even async validators that can run validation…as the user changes input value.…
Justin Schwartzenberger steps through the framework one feature at a time, focusing on the new component-based architecture of Angular 2. You'll learn what Angular is and what it can do, as Justin builds a full-featured web app from start to finish. After mastering the essentials, you can tackle the other project-based courses in our library and create your own Angular app.
