Live search through table rows

Question

I want to do a live search through the table rows, using jQuery, the "live" word is the key, because I want to type the keywords in the text input, on the same site and I'd like jQuery to automaticaly sort (or remove those who doesn't match the search query) the table rows.

Here is my HTML:

<table>
    <tr><th>Unique ID</th><th>Random ID</th></tr>
    <tr><td>214215</td><td>442</td></tr>
    <tr><td>1252512</td><td>556</td></tr>
    <tr><td>2114</td><td>4666</td></tr>
    <tr><td>3245466</td><td>334</td></tr>
    <tr><td>24111</td><td>54364</td></tr>
</table>

And if I would fe. search by the Unique ID, it should show the only rows that starts from the certain number for the Unique ID. Fe. if I would type '2' in the search input box, the following rows should stay, as they begin with 2:

<table>
    <tr><th>Unique ID</th><th>Random ID</th></tr>
    <tr><td>214215</td><td>442</td></tr>
    <tr><td>2114</td><td>4666</td></tr>
    <tr><td>24111</td><td>54364</td></tr>
</table>

If I would type 24, then there should be only one row visible as it begins from the 24:

<table>
    <tr><th>Unique ID</th><th>Random ID</th></tr>
    <tr><td>24111</td><td>54364</td></tr>
</table>

If you guys could give me some tips on how to do something like this I would appreciate it so much.

Thank you.

I'm not sure how efficient this is but this works:

$("#search").on("keyup", function() {
    var value = $(this).val();

    $("table tr").each(function(index) {
        if (index != 0) {

            $row = $(this);

            var id = $row.find("td:first").text();

            if (id.indexOf(value) != 0) {
                $(this).hide();
            }
            else {
                $(this).show();
            }
        }
    });
});​

I did add some simplistic highlighting logic which you or future users might find handy.

One of the ways to add some basic highlighting is to wrap em tags around the matched text and using CSS apply a yellow background to the matched text i.e: (em{ background-color: yellow }), similar to this:

// removes highlighting by replacing each em tag within the specified elements with it's content
function removeHighlighting(highlightedElements){
    highlightedElements.each(function(){
        var element = $(this);
        element.replaceWith(element.html());
    })
}

// add highlighting by wrapping the matched text into an em tag, replacing the current elements, html value with it
function addHighlighting(element, textToHighlight){
    var text = element.text();
    var highlightedText = '<em>' + textToHighlight + '</em>';
    var newText = text.replace(textToHighlight, highlightedText);
    
    element.html(newText);
}

$("#search").on("keyup", function() {
    var value = $(this).val();
    
    // remove all highlighted text passing all em tags
    removeHighlighting($("table tr em"));

    $("table tr").each(function(index) {
        if (index !== 0) {
            $row = $(this);
            
            var $tdElement = $row.find("td:first");
            var id = $tdElement.text();
            var matchedIndex = id.indexOf(value);
            
            if (matchedIndex != 0) {
                $row.hide();
            }
            else {
                //highlight matching text, passing element and matched text
                addHighlighting($tdElement, value);
                $row.show();
            }
        }
    });
});

Here's a version that searches both columns.

$("#search").keyup(function () {
    var value = this.value.toLowerCase().trim();

    $("table tr").each(function (index) {
        if (!index) return;
        $(this).find("td").each(function () {
            var id = $(this).text().toLowerCase().trim();
            var not_found = (id.indexOf(value) == -1);
            $(this).closest('tr').toggle(!not_found);
            return not_found;
        });
    });
});

François Wahl approach, but a bit shorter:

$("#search").keyup(function() {
    var value = this.value;

    $("table").find("tr").each(function(index) {
        if (!index) return;
        var id = $(this).find("td").first().text();
        $(this).toggle(id.indexOf(value) !== -1);
    });
});

Solution 4

Here is the pure Javascript version of it with LIVE search for ALL COLUMNS :

function search_table(){
  // Declare variables 
  var input, filter, table, tr, td, i;
  input = document.getElementById("search_field_input");
  filter = input.value.toUpperCase();
  table = document.getElementById("table_id");
  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") ; 
    for(j=0 ; j<td.length ; j++)
    {
      let tdata = td[j] ;
      if (tdata) {
        if (tdata.innerHTML.toUpperCase().indexOf(filter) > -1) {
          tr[i].style.display = "";
          break ; 
        } else {
          tr[i].style.display = "none";
        }
      } 
    }
  }
}

I took yckart's answer and:

• spaced it out for readability
• case insensitive search
• there was a bug in the comparison that was fixed by adding .trim()

(If you put your scripts at the bottom of your page below the jQuery include you shouldn't need document ready)

jQuery:

 <script>
    $(".card-table-search").keyup(function() {
        var value = this.value.toLowerCase().trim();

        $(".card-table").find("tr").each(function(index) {
            var id = $(this).find("td").first().text().toLowerCase().trim();
            $(this).toggle(id.indexOf(value) !== -1);
        });
    });
 </script>

If you want to extend this have it iterate over each 'td' and do this comparison.
