Form not validating
This is because the messages for each field are often identical.An alternative approach would be to use another constraint validation API method, set Custom Validity to set a completely custom message.Take this simple booking form: attribute for the label tag matches up with the id attribute of the associated input tag.
I found that using NVDA with IE10 caused the title attribute and the aria-describedby element's text to be read out, but using NVDA with Chrome and Firefox didn’t exhibit this behaviour. Later on we’ll revisit this and show you one solution using CSS3.Finally we covered how to disable HTML form validation, and detect whether form validation was available or not in case we have to support browsers that are yet to support this feature.Let me know what you think of all this in the comments.A few months ago Sandeep introduced us to the HTML Constraint API, showing how we can use the new HTML5 input types and attributes to validate our forms in the browser with minimal Java Script.Today I’m going to walk you through validating a simple booking form by using the Constraint API, and keep an eye on how you can make sure your forms stay accessible too.
One option is to not do anything and rely on your server-side validation only.
