JavaScript Filter results, but include first...

[lloydie11]

Hi,

I'm using the below code to filter a web dataset, which the first Column, and First Row are both defined as a header (TH),

This works in practice, and i get my results, but as it's also classifying my first header as a filterable object, i loose my top header, any ideas how i could change this so it still includes the first row/header in the outputted results,

   <script>
function myFunction() {
  var input, filter, table, tr, td, th, i, txtValue;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  table = document.getElementById("myTable");
  tr = table.getElementsByTagName("tr");
  for (i = 0; i < tr.length; i++) {
    td = tr[i].getElementsByTagName("th")[0];
    if (td) {
      txtValue = td.textContent || td.innerText;
      if (txtValue.toUpperCase().indexOf(filter) > -1) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    }       
  }
}
</script>

Thanks,

JS without HTML is worthless in most cases. Since I have no idea where ID = "myInput" is located I'm lost. Please give the HTML and the CSS for this.

That's ok, I increased the int for the array and it is now working.
