Can you only add a small number?

    if (!/^\d+$/.test(pnumber))
    {
      $(e).val(/^\d+/.exec($(e).val()));
    }
    return false;

the code I wrote can only accept the number
, but I think it is OK to add another condition "."
but only one point
the second point can also be eliminated. How can I write the
code? Die!
