TEST

test( str ) : Boolean

Tests for a match in its string parameter.

When you want to know whether a pattern is found in a string use the test method (similar to theString.search method); for more information (but slower execution) use the exec method (similar tothe String.match method). As with exec (or in combination with it), test called multiple times onthe same global regular expression instance will advance past the previous match.

function testinput(re, str){
    if (re.test(str))
        midstring = " contains ";
    else
        midstring = " does not contain ";
    document.write (str + midstring + re.source);
}
