Question 1 of 15
The readonly attribute is great for preventing users from changing data in an input control. However, the readonly attribute can’t be used for every input type.
Do you know which one?
Text
Date
Number
Checkbox
That was the correct answer, well done!
Sorry, that was the wrong answer
The readonly attribute doesn’t work on checkboxes because it prevents you from editing the fields value rather than the fields state. In the case of checkboxes when you click the checkbox you’re modifying the state (on/off) rather than the value.
