[thelist] How Do I Combine Two Regular Expressions into One?

[Steve Cook]

Hi James,

this seems to work for me...

function fnTrim(vStr) {
   return vStr.replace(/^\s*|\s*$/g,"");
}

The "pipe" separator is like an "OR" operator in the regex.

BTW - my JavaScript is so rusty that working out how to print the darn
results out to the page took me a few minutes :-) Dratted brackets!
