Doing this allows developers using our component to assign a label element to the input to get the appropriate level of accessibility.There is one trick though, we must pass the method passes back a callback to call whenever the user has touched the custom control.The type of this contribution should be available in the client SDK.
This post has been updated from an excerpt chapter from my new EBook Angular Form Essentials Custom form controls/inputs are a typical pattern in complex Angular applications.
It’s common to want to encapsulate HTML, CSS, and accessibility in an input component to make it easier to use in forms throughout the application.
The values for the inputs are provided by the users when they add it to the work item form and the values would be passed to the control contribution when its loaded on the form. This sample shows how to register an object that is called when various events happen on the work item form that may impact your contributed control.
It also shows how to read input values provided by user for this control.
This article has been updated to the latest version of Angular 8 and tested with Angular 7.
The content is likely be applicable for older Angular 2 or other previous versions.
The main difference between a control contribution and group and page contribution is that a control contribution can take a set of user inputs while group and page contributions can not.
To define the inputs for your control contribution, use configures which colors map to which values in the control.
Ideally, we would like them to integrate into Angular’s form system easily.
In this post, we will show how to create a switch component () which is essentially a checkbox with additional CSS and markup to get a physical switch like effect.
The switch component mostly mimics the behavior of a checkbox. In this component, we use a native checkbox and some HTML and CSS to create the switch effect.
