which java-script function can trim chars at left and right side of a string?

i.g.
original string: "\r hello \n\t ";
trimed string: "hello"

Do you want the original string to return the trimmed string?

function trim(str) {
s1 = str.replace(/^(\s)*/, '');
s2 = s1.replace(/(\s)*$/, '');
return s2;
}

assignments are expensive, it's faster this way:

function trim(str) {
return str.replace(/^\s*|\s*$/g, '');
}
