Validating user input with javascript

See a complete demo @Codepen The messages parameter is optional.

If you skip the messages parameter, the plugin will display default, auto-generated messages.

There are two keys to understanding why the automatic fallback works consistently in all major browsers: (unless "foo" is a recognized input type or "bar" is a recognized attribute of the input element).

For each of the new input types, we present a high-level description, an overview of the syntax, a description of the main attributes, a summary of which current browsers support it, and an example you can experiment with in your browser.

If you want to collect floating point numbers, use a non-integer for min or step.

This input type lets you collect a number (either integer or floating point). The exact value is not displayed to the user unless you use Java Script.

This includes a large bunch of sample code and a complete reference guide to all the built-in validation rules in the library.

If you imagine form as a dialog between your website and your user, the messages play an important role.

Don’t leave it to the auto-generated default messages.

Explain to your user what is wrong and suggest solutions.

For each type of input element, we use the code to detect if your browser supports it. You should normally supply all of value, min, and max.

Browsers that support this input type give inconsistent behavior when these attributes are omitted.
