I want to search on the Name and Country values columns with the text filter, but now I can only search on one column. How can I change the value of "tr[i].getElementsByTagName(‘td’)[0]" to filter on both columns?

I’ll be happy if you can help me.

<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search for names..">

<table id="myTable">
  <tr class="header">
    <th style="width:60%;">Name</th>
    <th style="width:40%;">Country</th>
  </tr>
  <tr>
    <td>Alfreds Futterkiste</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Berglunds snabbkop</td>
    <td>Sweden</td>
  </tr>
  <tr>
    <td>Island Trading</td>
    <td>UK</td>
  </tr>
  <tr>
    <td>Koniglich Essen</td>
    <td>Germany</td>
  </tr>
</table>

<script>
function myFunction() {
  // Declare variables
  var input, filter, table, tr, td, i, txtValue;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  table = document.getElementById("myTable");
  tr = table.getElementsByTagName("tr");

  // Loop through all table rows, and hide those who don't match the search query
  for (i = 0; i < tr.length; i++) {
    td = tr[i].getElementsByTagName("td")[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>

You can select both fields and ask it to match against either.

<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search for names..">
<table id="myTable">
  <tr class="header">
    <th style="width:60%;">Name</th>
    <th style="width:40%;">Country</th>
  </tr>
  <tr>
    <td>Alfreds Futterkiste</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Berglunds snabbkop</td>
    <td>Sweden</td>
  </tr>
  <tr>
    <td>Island Trading</td>
    <td>UK</td>
  </tr>
  <tr>
    <td>Koniglich Essen</td>
    <td>Germany</td>
  </tr>
</table>
<script>
function myFunction() {
  // Declare variables
  var input, filter, table, tr, tdName, tdCountry, i, txtValueName, txtValueCountry;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  table = document.getElementById("myTable");
  tr = table.getElementsByTagName("tr");

  // Loop through all table rows, and hide those that don't match the search query in either the Name or Country column
  for (i = 0; i < tr.length; i++) {
    tdName = tr[i].getElementsByTagName("td")[0];
    tdCountry = tr[i].getElementsByTagName("td")[1];
    if (tdName && tdCountry) {
      txtValueName = tdName.textContent || tdName.innerText;
      txtValueCountry = tdCountry.textContent || tdCountry.innerText;
      if (txtValueName.toUpperCase().indexOf(filter) > -1 || txtValueCountry.toUpperCase().indexOf(filter) > -1) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    }
  }
}
</script>

Try this,

<script>
function myFunction() {
  // Declare variables
  var input, filter, table, tr, td, i, txtValue,txtValue1;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  table = document.getElementById("myTable");
  tr = table.getElementsByTagName("tr");

  // Loop through all table rows, and hide those who don't match the search query
  for (i = 0; i < tr.length; i++) {
    td = tr[i].getElementsByTagName("td")[0];
    td1 = tr[i].getElementsByTagName("td")[1];
   
    if (td) {
      txtValue =  td.textContent || td.innerText ;
      txtValue1 =  td1.textContent || td1.innerText ;
       console.log(txtValue1);
      if (txtValue.toUpperCase().indexOf(filter) > -1 || txtValue1.toUpperCase().indexOf(filter) > -1) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    }
  }
}
</script>
