How to filter/search a table

Learn how to use JavaScript to create filterable tables.

Create a filterable table

Step 1 - Add HTML:

<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>

Step 2 - Add CSS:

Set the styles for the input element and the table:

#myInput {
  background-image: url('/css/searchicon.png'); /* Add a search icon to the input box */
  background-position: 10px 12px; /* Position the search icon */
  background-repeat: no-repeat; /* Do not repeat icon images */
  width: 100%; /* Full width */
  font-size: 16px; /* Increase font size */
  padding: 12px 20px 12px 40px; /* Add some inner padding */
  border: 1px solid #ddd; /* Add a gray border */
  margin-bottom: 12px; /* Add some space below the input box */
}
#myTable {
  border-collapse: collapse; /* Merge borders */
  width: 100%; /* Full width */
  border: 1px solid #ddd; /* Add a gray border */
  font-size: 18px; /* Increase font size */
}
#myTable th, #myTable td {
  text-align: left; /* Align text to the left */
  padding: 12px; /* Add padding */
}
#myTable tr {
  /* Add bottom border to all table rows */
  border-bottom: 1px solid #ddd;
}
#myTable tr.header, #myTable tr:hover {
  /* Add grey background color to table header and when mouse hovers */
  background-color: #f1f1f1;
}

Step 3 - Add JavaScript:

<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");
  // Traverse all table rows and hide those that do not 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>

Try it yourself

Tip:If you want to perform a case-sensitive search, please remove toUpperCase().

Tip:If you want to search for country (index 1) instead of 'Name' (index 0), please set tr[i].getElementsByTagName('td')[0] Change to [1].
