May 21, 2020Day 18 - Inline form validation with keypress event listener
Attached keyboard event listener ‘keyup’ to username field - so this is the 'target' of the listener. So whenever a key is pressed on the keyboard, the event fires and my callback function runs which takes in the keyboard event object.

Then used the test() method to compare the value property of the keyboard event object with the regex pattern to see if it passed the test and validated.

Wrote a cople of CSS classes (success and error) to make the border of the username field red or green.

Then wrote an IF statement within the callback function to apply the green ‘success’ border to the username field if a valid username is entered and red ‘error’ border if not. This was done with the setAttributre method which overrides the class attribute as appropriate.

Learned about the test() method, which compares a regex with a string. This returns a boolean value which I used as the test value in an IF statement when showing the correct validation message to the user

May 19, 2020Day 16 - Form events and basic REGEX
Learnt when attaching an event listener on a form, you always attach it to the element and NOT to the button itself.

Learnt about using the ‘event object’ and what you can do with it

Prevent default 'refresh' behaviour of the submit event

Firefox devtools is better than Chrome here as it visually shows you when you have selected the field.

Get a reference to the username field and log it to the console. Clue - use the ID of the input field.

Regex basics. A regular expression (regex) is a matching pattern that only allows a certain combination or pattern of characters to be entered i.e. 4-18 characters and only containing letters and numbers
