Character functions are those that allow the user to work with characters. These functions include the ability to check whether a character is a digit, an alphabetic character, and whether the character is upper or lower case.
<SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript" SRC="JS_Vision_Character.js"></SCRIPT>
When using these functions, the argument passed to them should be a single character. If a string is passed, then the first character in the string is evaluated.
For more information on the SRC
attribute of the SCRIPT
tag, see JavaScript Vision
