I have a text input, which could be any combination of alphanumeric characters.
<input type="text" name="example">
Here's my problem.
If the user is entering letters only, or a combination of letters and numbers, then no problem, let them submit it.
However, if the user is entering an integer, any value above 99 will always be an invalid entry (as far as the backend is concerned). So on the front end, I would like to prevent them from entering any integer three or more digits long.
