Specify button type

Specify button type (button-type)

button-type checks if all buttons have a type attribute set.

Why is this important?

The default type for <button> is submit (not type="button" as one might expect). This can lead to surprising keyboard behavior within a form.

The best way to avoid unexpected surprises is to always explicitly set a type on <button>s.

What does the hint check?

This hint checks whether the type attribute of a <button> is explicitly set.

Examples that trigger the hint


Examples that pass the hint

<button type="submit"></button>
<button type="button"></button>

How to use this hint?

This package is installed automatically by webhint:

npm install hint --save-dev

To use it, activate it via the .hintrc configuration file:

    "connector": {...},
    "formatters": [...],
    "parsers": [...],
    "hints": {
        "button-type": "error"

Note: The recommended way of running webhint is as a devDependency of your project.
