修剪前导和尾随空格

Posted 2021-02-27

Trims leading and trailing spaces from a string value and returns the result as a new string.

function trimWhitespace(value) {
    var result = value.match(/^s*(.*S)s*$/);
    if (result !== null && result.length === 2)
        return result[1];
    else
        return value;
};
