Answer 1

Try something like this.

var s:String = "I am good going"; // or input.text

Alert.show(s.split(" ").length.toString());

In this s.split(" ").length - 1 is the number of spaces

Answer 2

A:

If you want a Regex, this will match any string which contains more than one space:

/.* .* /

<mx:TextInput x="102" y="99" restrict="A-Z a-z /.* .* /" id="sdsd"/>

The above does not work

2009-12-22 08:05:58

That doesn't work because the `restrict` property doesn't accept regular expressions.

Answer 3

+1 A:

Better solutions would be to catch the change event, then cancel it if it would add a second space, or use a validator:

<mx:RegExpValidator
    source="{oneSpace}" property="text" 
    expression=".* .* " />
<mx:TextInput id="oneSpace" />
