Be careful when using buttons without a "type" attribute

Be careful when using buttons without a type attribute, since browsers will consider them the default submit button of a form.

Suppose you have this form:

Copy
<form action="/save"> <input type="text" /> <button onclick="alert('Alert!')">Alert</button> <button type="submit">Save</button> </form>

If you press the enter key inside in the text input, browsers will trigger the first button and show the alert.

To fix this, add a type="button" attribute to the first button.

Does your version of Ruby on Rails still receive security updates?
Rails LTS provides security patches for old versions of Ruby on Rails (3.2 and 2.3).
