I need the correct regular expression for checking input text in HTML matching this format:
- Initially, any number of letters (uppercase or lowercase) or white spaces may appear.
- Then a comma followed by a blank space (, ) will appear.
- After that, there must be a blank space.
- Finally, after the preceding white space, 3 to 10 letters (without white spaces) will appear in parentheses.
Example: Street One, 13 (City)
I think I have to add anchors at the beginning and at the end, but I don't know how to join everything so that the complete regular expression remains.
<input type="text" placeholder="Your address city" **pattern="^\[a-z]i\s-\s[0-9]{2}\([a-z]{1,3})$"** required>
