Create A Filtered Table

Step 1) Add HTML:

Example

<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:

Style the input element and the table:

Example

#myInput {
    background-image: url('/css/searchicon.png'); /* Add a search icon to input */
    background-position: 10px 12px; /* Position the search icon */
    background-repeat: no-repeat; /* Do not repeat the icon image */
    width: 100%; /* Full-width */
    font-size: 16px; /* Increase font-size */
    padding: 12px 20px 12px 40px; /* Add some padding */
    border: 1px solid #ddd; /* Add a grey border */
    margin-bottom: 12px; /* Add some space below the input */
}

#myTable {
    border-collapse: collapse; /* Collapse borders */
    width: 100%; /* Full-width */
    border: 1px solid #ddd; /* Add a grey border */
    font-size: 18px; /* Increase font-size */
}

#myTable th, #myTable td {
    text-align: left; /* Left-align text */
    padding: 12px; /* Add padding */
}

#myTable tr {
    /* Add a bottom border to all table rows */
    border-bottom: 1px solid #ddd;
}

#myTable tr.header, #myTable tr:hover {
    /* Add a grey background color to the table header and on hover */
    background-color: #f1f1f1;
}

Step 3) Add JavaScript:

Example

<script>
function myFunction() {
  // Declare variables
  var input, filter, table, tr, td, i;
  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) {
      if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    }
  }
}
</script>

Tip: Remove toUpperCase() if you want to perform a case-sensitive search.

Tip: Change tr[i].getElementsByTagName('td')[0] to [1] if you want to search for "Country" (index 1) instead of "Name" (index 0).

Tip: Also check out Filter List.

Tip: You can also use our JavaScript library to filter elements: W3.JS.
