report中 用js写千位分隔符

js写千位分隔符

function format_with_mod(number) {
    var n = number;
    var r = "";
    do {
        mod = n % 1000;
        n = n / 1000;
        r = ~~mod + (!!r ? "," + r : "")
    } while (n > 1)

    var strNumber = number + "";
    var index = strNumber.indexOf(".");
    if (index > 0) {
        r += strNumber.substring(index);
    }
    return r;
}

谢谢，已经实现了
