Cart page on click update cart bind javascript multiple inputs autocomplete function


custom variable inputs for each cart item on the cart page with a javascript autocomplete function for the input. The autocomplete working when the cart page loads. On changing the quantity and clicking update cart the javascript autocomplete function is lost. If the cart page is fully refreshed the autocomplete function works again. The function is losing the binding on partial page refresh when update cart is clicked.

I have tried using $(document).ready(function() (commented out in the code snip) but the browser throws a ‘$ is not a function’ for the $(document).ready(function()

How do I implement the bind so the autocomplete function works continuously?


cart loop {


is_sold_individually() ) {

$product_quantity = sprintf( ‘1 ‘, $cart_item_key );

} else {

$product_quantity = woocommerce_quantity_input(
‘input_name’ => “cart[{$cart_item_key}][qty]”,
‘input_value’ => $cart_item[‘quantity’],
‘max_value’ => $mx_qty,
‘min_value’ => ‘1’,
‘product_name’ => $_product->get_name(),





echo apply_filters( ‘woocommerce_cart_item_quantity’, $product_quantity, $cart_item_key, $cart_item ); // PHPCS: XSS ok.



      <input id="myInput<?php echo $i.$cart_item_key;?>" class='autoc' value="<?php echo $cart_item['woo_number'][$i];?>" name="woo_number<?php echo $cart_item_key;?>[]" type="text" autocomplete="off" minlength="1" maxlength="4" min="1"  border='1' data-product="<?php echo $product_id; ?>" required>





function autocomplete(inp, arr) {
/*the autocomplete function takes two arguments,
the text field element and an array of possible autocompleted values:*/
var currentFocus;
/*execute a function when someone writes in the text field:*/
inp.addEventListener(“input”, function(e) {
var a, b, i, val = this.value;
var el_counter = 0;

if (!val) { return false;}

b.innerHTML += “”;

/*execute a function when someone clicks on the item value (DIV element):*/
b.addEventListener(“click”, function(e) {
/*insert the value for the autocomplete text field:*/

if (x) x[currentFocus].click();
function addActive(x) {
/*a function to classify an item as “active”:*/
if (!x) return false;
/*start by removing the “active” class on all items:*/
if (currentFocus >= x.length) currentFocus = 0;
if (currentFocus // $(document).ready(function() {
// $(‘.woocommerce’).on(‘change’, ‘.autoc’, function(){

/An array containing all the available ltd ed nos/
var arrlist = ”;
arrlist = [];

var jsqty = 0;
var jskey = ”;

jsqty = "";
jskey = "";

var str1 = ”;
str1 = ‘myInput’;
/initiate the autocomplete function on the "myInput" element, and pass along the countries array as possible autocomplete values:/
for (var i = 0; i < jsqty; i++) {
var num = i;
var str2 = num.toString();
var str3 = str1.concat(str2);
var myInput = str3.concat(jskey);


} //end cart loop`
