charCodeAt (String.charCodeAt method)

Returns a 16-bit integer from 0 to 65535 that represents the character specified by index. If index is not a number from 0 to string.length - 1, NaN is returned.

This method is similar to String.charAt() except that the returned value is a 16-bit integer character code, not a character.

Availability: ActionScript 1.0; Flash Player 5

Parameters

index:Number - An integer that specifies the position of a character in the string. The first character is indicated by 0, and the last character is indicated by my_str.length - 1.

Returns

Number - An integer that represents the character specified by index.

Example

In the following example, this method is called on the first letter of the string "Chris":

var my_str:String = "Chris";
var firstChar_num:Number = my_str.charCodeAt(0);
trace(firstChar_num); // output: 67
