Recipe 8.8 Restricting the Maximum Field Length
8.8.1 Problem
You want to limit
the length of the string input in a
text field.
8.8.2 Solution
Set the text field's maxChars
property.
8.8.3 Discussion
By default, an input text field allows a user to type in as many
characters as she desires. However, you may have good reason to want
to set a maximum. For example, if an input field prompts a user for
her two-character country code, you might want to prevent the user
from entering more than two characters. Setting the
maxChars property to a number limits the user
input to that many characters.
myTextField.maxChars = 6; // Maximum of six characters can be input
Set maxChars to null to allow
an entry of unlimited length.
