How can I change the search form to separate single digits fields?

Question

I have a multiple character search field which fetches WoocCommerce product data via AJAX and works correctly.

Current search field

I need to split my search field into single 6 digit boxes, this is an example of the form I could use:

<form>
     <input type="number" name="abc" min="0" max="9">
      <input type="number" name="abc" min="0" max="9">
      <input type="number" name="abc" min="0" max="9">
      <input type="number" name="abc" min="0" max="9">
      <input type="number" name="abc" min="0" max="9">
      <input type="number" name="abc" min="0" max="9">
        </form>

How can I split the string of my search field into multiple single digit search fields?

My Front End Code

<input type="text" name="keyword" id="keyword" onkeyup="fetch()">
<div id="datafetch">Your numbers will show here</div>
<script>
function fetch(){
    $.post('<?php echo admin_url('admin-ajax.php'); ?>', 
    {'action':'my_action'},
    function(response){
        $('#datafetch').append(response);
        console.log(result);
    });
}
</script>

Code in Functions.php

add_action('wp_ajax_data_fetch' , 'data_fetch');
add_action('wp_ajax_nopriv_data_fetch','data_fetch');
function data_fetch(){
   $myquery = esc_attr( $_POST['keyword'] );
}

Use your suggested script but put tab index per each input field:

then do some UX tasks:

• since you specify type='number' then you cant use maxlength attribute to prevent entrance of more than 1 digit per input so u must handle it in your js.
• let user can back to previous input by pressing backspace
• replace current input value if the user focus manually on it and press another number
• do some UI works !

now you have your separated input boxes that work user-friendly. but you must integrate their input value before submitting to WordPress admin-ajax for passing to your function, or you can send them individually and integrate them in server-side function, do what you want.

here is the demo:

 function fetch(){ $('#keyword').val() = $('#input1').val() + $('#input2').val() + $('#input3').val() + $('#input4').val() + $('#input5').val() + $('#input6').val(); //rest of your function } $(function() { $("input").keydown(function (e) { if(e.keyCode == 8) { $(this).prev().focus(); } if (this.value.length == this.maxLength) { $(this).val(''); } }); $("input").keyup(function () { if (this.value.length == this.maxLength) { $(this).next().focus(); } }); });

 input { height: 21px; background: #f1f1f1; border: 1px #c9c9c9 solid; border-radius: 3px; -moz-appearance: none; appearance: none; text-align: center; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <form> <input id="input1" type="number" min="0" max="9" tabindex="1" maxlength="1"> <input id="input2" type="number" min="0" max="9" tabindex="2" maxlength="1"> <input id="input3" type="number" min="0" max="9" tabindex="3" maxlength="1"> <input id="input4" type="number" min="0" max="9" tabindex="4" maxlength="1"> <input id="input5" type="number" min="0" max="9" tabindex="5" maxlength="1"> <input id="input6" type="number" min="0" max="9" tabindex="6" maxlength="1"> </form>
