Checking a Box That Reloads the Page and Loses Entries
3.2.2 — On Input
Scenario
Setting
A language-learning app's lesson screen
What’s wrong
Checking a box reloading the page and losing surrounding context/entries.
Example
<select onchange="location.href=this.value">Why it matters
Keyboard and screen-reader users, and people who need predictable form behavior.
How to test
Check a checkbox without pressing submit: if the page reloads and loses the surrounding context/other entries, it fails.
How to fix
Changing a field's value must not navigate, submit, close, or change context unless the user was told beforehand or explicitly confirms.
<select onchange="updatePreview()"></select><button onclick="navigate()">Go</button>Changing a value should update state, not silently navigate — let the user confirm with an explicit action.
Outcome
On a language-learning app's lesson screen, this barrier is gone for keyboard and screen-reader users — they can finish what they came here to do.
Who is affected
Keyboard and screen-reader users, and people who need predictable form behavior.
