You may use a trim function (based on Regular Expressions)

function alltrim(str) {
return str.replace(/^\s+|\s+$/g, '');

New versions of Safari, Chrome , Opera and Firefox have a native string trim,
and IE9 does, as well. You could substitute Kor's method, if trim is not already defined

return this.replace(/^\s+|\s+$/g,'');
