html jquery forms radio-button autoscroll

How to autoscroll to the form area when a field is not entered while submitting

I wish to submit a form, but when the field is not entered, it should auto-point to that area. I have radio buttons. When it is not clicked, it should auto-scroll to the radio button area. When I execute my code, it is not autoscrolling to radio button but text fields are autoscrolling.

Whenever I try to submit the form, it is not autoscrolling,it only shows the error condition.How to fix this

$('.sellingFormSave').submit(function(e) {
  //e.preventDefault();
  $('.form_error').remove();
  var count = 0;
  if (!$('[name=condition]:checked').val()) {
    $('.condition_radio .wrapper').after('<label class="form_error" style="color:red">Select the condition of the trucks.</label>');
    count++;
  }
  if ($('[name=product_id]').val() == '') {

    var qty = 0;

    if (count > 0) {
      $('[type=submit]').attr('disabled', false);
      return false;
    }
  }
});

Solution

You do not have a field called product_id
You ignore the other fields if a radio is checked. Since the radios are required, you cannot trigger any error for the "name" or "city" field since the browser will not let you submit without choosing a radio
What is product_name and why do you set qty to 0 without using it.

Here is a demo. I push the save button so you can see the browser will focus on the empty name.

Next time please have the code match the HTML

$('#sellingFormSave').on("submit", function(e) {
  $('.form_error').remove();
  if (!$('[name=condition]:checked').val()) {
    $('.condition_radio .wrapper').after('<label class="form_error" style="color:red">Select the condition of the trucks.</label>');
  }
  if ($('[name=name]').val() == '') {
    e.preventDefault()
    $('[name=name]').focus();
  }
});
