Synopsis
string.length
Access
Read-only
Description
The length
property returns the number of
characters in string
. Note that a null
character (ASCII 0) does not signal the end of a string, as it would
in some languages, but neither is it counted in the string’s
length
. For example:
// Create the string "A" + null + "B" var myString = String.fromCharCode(65,0,66); trace(myString.length); // Displays: 2 (The null character is ignored)
Example
var myString = "hello"; trace (myString.length); // Displays: 5 trace ("hello".length); // Displays: 5 // Here we convert the number 1000 to a // string in order to test its length var age = 1000; // Display an error message if the number has the wrong number of digits. if (String(age).length != 2) { trace ("Please enter a two-digit number"); }
