What is the best way to trim() in javascript

Question

The question says it all; JS doesn\'t seem to have a native trim() method.

Answer 1

You can use following ...

function trim(str) {
    try {
        if (str && typeof(str) == 'string') {
            return str.replace(/^\s*|\s*$/g, "");
        } else {
            return '';
        }
    } catch (e) {
        return str;
    }
}
