How can I find a number in a string using Flex?

Question

I want to replace a number with a character at runtime like this:

Input:

ask 1234 question

Result:

ask * question

What is the best way to accomplish this?

Answer 1

You could use a regular expression.

Answer 2

Use a Regex to match a number and then do a string replace. Something along the lines of:

var str:String = "ask 1234 question"; // your string
var pattern:RegExp = /\d+/ ; // a regular expression that matches numbers
trace(str.replace(pattern, "*"));

Look up the flex 3.0 documentation for both String and Regex. Happy coding!
