How to filter table that contains input cells using javascript?

Question

I have a table that take inputs and creates item names and descriptions based on the inputs. Is it possible using Javascript to filter a table that picks up inputs as data? i've found a lot of functioning filters but none seem to work with input cells

i've created a basic version of my table and added a jQuery filter i'm trying to use. As you can see the filter isn't functioning properly with the cell inputs - It also won't remove the filter once you've inputted into the search cell once. i've kept the function that creates new rows as i feel this might be causing problems as well.

function cloneRow() {
    var rowAmmount = document.getElementById("rowAmmount").value;
    var getTotalRows = $('table > tbody').children().length;
    for (var i = -1; i < rowAmmount-1;i++) {
      var row = document.getElementById("row"); // find row to copy
      var table = document.getElementById("table"); // find table to append to
      var clone = row.cloneNode(true); // copy children too
      clone.id = "newRow" + (getTotalRows + i); // change id or other attributes/contents
      clone.classList.remove('hidden');
      table.appendChild(clone); // add new row to end of table
      $('#newRow' + (getTotalRows + i)).children().each(function() {
        $(this).children().attr('id', $(this).children().attr('id') + (getTotalRows + i));
      });
    }
}

var $rows = $('#table tr');

$('#search').keyup(function() {
var val = '^(?=.*\\b'
        + $.trim($(this).val()).split(/\s+/).join('\\b)(?=.*\\b')
        + ').*$',
    reg = RegExp(val, 'i'),
    text;

$rows.show().filter(function() {
    text = $(this).text().replace(/\s+/g, ' ');
    return !reg.test(text);
}).hide();
});

First, your HTML is a bit sloppy: I had to change <<input ... to <input ....
And some <img> were followed by </output>

The main issue is that you are using .text() on the table rows, but instead you should be using .val() on the inputs inside the rows.

Also I used a simple indexOf() to eliminate the risk of the regex being wrong.

Working demo (stripped most of the redundant or unneeded elements):

var $rows = $('#table tr');

$('#search').keyup(function() {
  var searchText = $(this).val();
  $rows
    .show()
    .filter(function() {
      var $inputs = $(this).find("input:text");
      var found = searchText.length == 0; // for empty search, show all rows
      for (var i=0; i < $inputs.length && !found; i++) {
        var text = $inputs.eq(i).val().replace(/\s+/g, ' ');
        found = text.length > 0 && text.indexOf(searchText) >= 0;
      }
      return !found;
   })
   .hide();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<input type="text" id="search" placeholder="Type to search">
<table>
  <thead>
    <tr>
      <th>Product Code</th>
      <th>Item Name</th>
      <th>Long Description</th>
  </thead>
  <tbody  id="table">
    <tr id="row">
      <td><input id="productId" placeholder="Input"></td>
      <td><input id="itemname" placeholder="Input"></td>
      <td><input id="long" placeholder="Input"></td>
    </tr>
    <tr id="newRow0">
      <td><input id="productId0" placeholder="Input"></td>
      <td><input id="itemname0" placeholder="Input"></td>
      <td><input id="long0" placeholder="Input"></td>
    </tr>
  </tbody>
