A checklist for building forms with custom elements to 'A checklist for building forms with custom elements' # Until these features are fully implemented in all major browsers (ahem, Safari), it’s up to front-end developers to ensure that custom form elements work. We also have the global is attribute for extending built-in HTML form elements, but are still waiting on full support in Safari (Mac or iOS). Browser support remains incomplete (no Safari) in the meantime there’s a polyfill. Think: automatic form data serialization like the good old days, just drop in your form elements, specify how and where to submit, and the browser does the rest. The ElementInternals API is meant to, essentially, apply HTML’s form capabilities to custom elements. Web standards and browser vendors are getting there to 'Web standards and browser vendors are getting there' # That would be my ideal scenario: to seamlessly use HTML form controls in the context of web components. We need custom elements to function exactly like their HTML counterparts - with a focus state, keyboard events, and when set up with a proper and submit button, data validation and serialization - and in ways that leverage HTML itself. When it comes to form composition, though, they require that we reinvent the wheel to some extent. They changed how we think about extensibility in complex, large scale sites and applications. Web component standards came on the scene about 11 years ago and introduced the concept of custom elements: blank canvases that we can define, encapsulate, and reuse in ways that we can’t with plain HTML. (Before we continue, I’m going to assume you’re already sold on the value of using web components and shadow DOM encapsulation, and have a working knowledge of web component standards/APIs and how to construct a basic custom element.) The state of custom form elements in 2022 to 'The state of custom form elements in 2022' # In this post I review what we can do now with custom elements in forms to ensure they behave as expected, and what’s on the horizon to simplify this process. Arduino simulator! Write Arduino code right in iCircuit to create advanced microcontroller-based designs.Custom elements can be efficient and powerful UI building blocks, especially for large scale applications, but when it comes to building forms they need help.Scope data can even be exported for offline analysis. You can even export your circuits and PNGs, PDFs, and SVG files so that they are easy to include in reports or web sites. The scope can simultaneously track many signals over time and features a variety of automatic modes that make it easy for you to grasp the behavior of your circuit. If you want to see how a value changes over time, then you can add values to the built-in oscilloscope. The app features a multimeter that you use to probe around the circuit to instantly read voltages and currents. The app has everything from simple resistors, to switches, to MOSFETS, to digital gates. There are over 30 elements you can use to build your circuits. Instead, you just play with the circuit as you normally would, with the power on! You do not stop to take a measurement or spend a lot of time configuring reports. It's just like working with the real circuit. But iCircuit is unlike other CAD programs because it is always simulating. You use it as you would any CAD program: you add elements, connect them together, and set their properties. It is the perfect companion to students, hobbyists, and engineers. Its advanced simulation engine can handle both analog and digital circuits, Arduino microcontrollers, and features realtime always-on analysis. ICircuit is the easiest way to design and experiment with circuits.
