How to write jquery If else statement?

Try jQuerys toggle() method:

$(function() {
    $(#reg).click(function () {
        $(#frm01).toggle(1000);
    });
});

You dont need jQuery to use if-else statements; Javascript implements those natively…

$(function() {
    $(#reg).click(function () {
        if ($(#frm01).is(:visible))
            $(#frm01).slideUp(1000);
        else
            $(#frm01).slideDown(1000);
    });
});

try this:

$(document).ready(function() {
   $(#reg).click(function () {
    if ($(#frm01).is(:hidden)) {
      $(#frm01).show(slide, { direction: down }, 1000);
    } else {
      $(#frm01).hide(1000);
    }
  });
});

  $(#reg).on(click, function () {
    $(#frm01:hidden).show(slide, { direction: down }, 1000);
    $(#frm01:visible).hide(slide, { direction: up }, 1000);
  });

or

  $(#reg).toggle(
    function () {
      $(#frm01).show(slide, { direction: down }, 1000);
    },
    function(){
      $(#frm01).hide(slide, { direction: up }, 1000);
    }
  );
