check for valid 5 and 6 digit zipcode - php

Question

I am able to autofill state,city and area based on 6 digit zipcode.The issue comes when i want to check for validity of zipcode starting from 5th digit.I know it will show invalid zip code error as i am comparing the value against database value..Here goes the code i have used.
Is there a way i can hide error of invalid zip code after 5th digit while still continuing to validate after 5th digit of zipcode?
<script>
require([
'jquery'
],function($){
$(document).ready(function(){
$('#seller_zipcode').keyup(function() {
pincode = $('#seller_zipcode').val();
pincode1 = $('#seller_zipcode').slice(0,-1);
//pincode1 = pincode.slice(0,-1);
//console.log(pincode1);
if(pincode.length == 6 || pincode1.length == 5){
$.ajax({
type: 'POST'
,url: "<?php echo $block->getUrl('marketplace/zipcode/zipcode');?>"
,data: {pincode : pincode}
,success: function(result){
var finalresult = $.parseJSON(result);
console.log(finalresult);
if(finalresult.state != null){
$('#state').val(finalresult.state);
$('#seller_district').val(finalresult.district);
$('#seller_taluka').val(finalresult.area);
$('#zip_error').removeClass('mage-error');
$('#zip_error').removeAttr('generated');
$('#zip_error').html("");
}
else{
$('#state').val("");
$('#seller_district').val("");
$('#seller_taluka').val("");
$('#zip_error').removeClass('mage-error');
$('#zip_error').addClass('mage-error').html("Zip Code invalid").show();
$('#zip_error').attr('generated','true');
}
}
});
}
});

Try doing this:
<script>
require([
'jquery'
],function($){
$(document).ready(function(){
$('#seller_zipcode').keyup(function() {
//Reset the zip error
$('#zip_error').removeClass('mage-error');
$('#zip_error').removeAttr('generated');
$('#zip_error').html("");
pincode = $('#seller_zipcode').val();
pincode1 = $('#seller_zipcode').slice(0,-1);
//pincode1 = pincode.slice(0,-1);
//console.log(pincode1);
if(pincode.length == 6 || pincode1.length == 5){
$.ajax({
type: 'POST'
,url: "<?php echo $block->getUrl('marketplace/zipcode/zipcode');?>"
,data: {pincode : pincode}
,success: function(result){
var finalresult = $.parseJSON(result);
console.log(finalresult);
if(finalresult.state != null){
$('#state').val(finalresult.state);
$('#seller_district').val(finalresult.district);
$('#seller_taluka').val(finalresult.area);
$('#zip_error').removeClass('mage-error');
$('#zip_error').removeAttr('generated');
$('#zip_error').html("");
}
else{
$('#state').val("");
$('#seller_district').val("");
$('#seller_taluka').val("");
$('#zip_error').removeClass('mage-error');
$('#zip_error').addClass('mage-error').html("Zip Code invalid").show();
$('#zip_error').attr('generated','true');
}
}
});
}
});
