public maxChars : Number

Indicates the maximum number of characters that the text field can contain. A script may insert more text than maxChars allows; the maxChars property indicates only how much text a user can enter. If the value of this property is null, there is no limit on the amount of text a user can enter.

Example

The following example creates a text field called age_txt that only lets users enter up to two numbers in the field.

this.createTextField("age_txt", this.getNextHighestDepth(), 10, 10, 30, 22);
age_txt.type = "input";
age_txt.border = true;
age_txt.maxChars = 2;
