You
can use the following operators to compare strings:
<
,
<=
,
!=
,
==
,
=>
,
and
>
. These operators can be used with conditional
statements, such as
if
and
while
,
as the following example shows:
var str1:String = "Apple";
var str2:String = "apple";
if (str1 < str2)
{
trace("A < a, B < b, C < c, ...");
}
When using these operators with strings, ActionScript considers
the character code value of each character in the string, comparing
characters from left to right, as in the following:
trace("A" < "B"); // true
trace("A" < "a"); // true
trace("Ab" < "az"); // true
trace("abc" < "abza"); // true
Use the
==
and
!=
operators
to compare strings with each other and to compare strings with other
types of objects, as the following example shows:
var str1:String = "1";
var str1b:String = "1";
var str2:String = "2";
trace(str1 == str1b); // true
trace(str1 == str2); // false
var total:uint = 1;
trace(str1 == total); // true
