    if ($.isNumeric(num)) {
        var DIGIT_PATTERN = /(^|\s)\d+(?=\.?\d*($|\s))/g;
        var MILLI_PATTERN = /(?=(?!\b)(\d{3})+$)/g;
        return num.toString().replace(DIGIT_PATTERN, function (m) {
            return m.replace(MILLI_PATTERN, ',');
        });
    } else {
        return num;

// 删除数字千分符
function nonIntcomma (str) {
