Trim space attempt 1

[cleanair4me]

I want to make sure at least 3 characters are entered into a search field.
For example I dont want this to go by where it has spaces in beginning and space between 2 characters: a b

I tried the below regular expression but it didnt capture the spaces in between the characters. Please advise how I can do it?

/^\s+|\s+$/g,""

>/^\s+|\s+$/g,""
In what context this expression is taken from?

I guess this is what you are after.
[tt]
s=" a b"; //retrieve from some element
var am;
am=s.match(/\S/g);
if (am!=null && am.length>2) {
return true; //validated
} else {
return false; //invalidated
}
[/tt]
