Question

How would I go about passing function parameters into a regex query?
Many thanks.

function match(str, arg1, arg2){
   var result = str.match(/(arg1 | arg2)/m);
   log(result) //null
}

match('claire nick steve', 'nick','steve');

You need to pass a normal string to the Regex constructor, like this:

var result = str.match(new Regex("(" + arg1 + "|" + arg2 + ")", "m");

If you use backslashes in the regex, you’ll need to escape them (\\) since it’s normal string literal.
