React, how to make a checked checkbox editable
How to add a checkbox that defaults to checked but it's editable in React
I had a checkbox in a React component:
<input name="enable" type="checkbox" />and I wanted it to be checked by default, yet the user could change its value.
Using
<input name="enable" type="checkbox" checked="checked" />didn’t work. The checkbox state could not be changed.
The solution was to use the defaultChecked attribute:
<input name="enable" type="checkbox" defaultChecked={true} />If the checkbox needs to be checked depending if the value was checked in a variable (for example in an editing form when you are getting the actual value from the database) you can use
<input name="enable" type="checkbox" defaultChecked={existing_enable_value} />download all my books for free
