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 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.

Here is something you can do with Ajax, PHP and JQuery. Hope this helps or gives you a start. Check the mysql query in php. It matches the pattern starting from first.

See live demo and source code here.

http://purpledesign.in/blog/to-create-a-live-search-like-google/

Create a search box, may be an input field like this.

<input type="text" id="search" autocomplete="off">

Now we need listen to whatever the user types on the text area. For this we will use the jquery live() and the keyup event. On every keyup we have a jquery function “search” that will run a php script.

Suppose we have the html like this. We have an input field and a list to display the results.

 <div class="icon"></div>
 <input type="text" id="search" autocomplete="off">
 <ul id="results"></ul>

We have a Jquery script that will listen to the keyup event on the input field and if it is not empty it will invoke the search() function. The search() function will run the php script and display the result on the same page using AJAX.

Here is the JQuery.

$(document).ready(function() {  

    // Icon Click Focus
    $('div.icon').click(function(){
        $('input#search').focus();
    });

    //Listen for the event
    $("input#search").live("keyup", function(e) {
    // Set Timeout
    clearTimeout($.data(this, 'timer'));

    // Set Search String
    var search_string = $(this).val();

    // Do Search
    if (search_string == '') {
        $("ul#results").fadeOut();
        $('h4#results-text').fadeOut();
    }else{
        $("ul#results").fadeIn();
        $('h4#results-text').fadeIn();
        $(this).data('timer', setTimeout(search, 100));
    };
});


// Live Search
// On Search Submit and Get Results
function search() {
    var query_value = $('input#search').val();
    $('b#search-string').html(query_value);
    if(query_value !== ''){
        $.ajax({
            type: "POST",
            url: "search_st.php",
            data: { query: query_value },
            cache: false,
            success: function(html){
                $("ul#results").html(html);

            }
        });
    }return false;    
}

}); In the php, shoot a query to the mysql database. The php will return the results that will be put into the html using AJAX. Here the result is put into a html list.

Suppose there is a dummy database containing two tables animals and bird with two similar column names ‘type’ and ‘desc’.

//search.php
// Credentials
$dbhost = "localhost";
$dbname = "live";
$dbuser = "root";
$dbpass = "";

//  Connection
global $tutorial_db;

$tutorial_db = new mysqli();
$tutorial_db->connect($dbhost, $dbuser, $dbpass, $dbname);
$tutorial_db->set_charset("utf8");

//  Check Connection
if ($tutorial_db->connect_errno) {
    printf("Connect failed: %s\n", $tutorial_db->connect_error);
    exit();

$html = '';
$html .= '<li class="result">';
$html .= '<a target="_blank" href="urlString">';
$html .= '<h3>nameString</h3>';
$html .= '<h4>functionString</h4>';
$html .= '</a>';
$html .= '</li>';

$search_string = preg_replace("/[^A-Za-z0-9]/", " ", $_POST['query']);
$search_string = $tutorial_db->real_escape_string($search_string);

// Check Length More Than One Character
if (strlen($search_string) >= 1 && $search_string !== ' ') {
    // Build Query
    $query = "SELECT *
        FROM animals
        WHERE type REGEXP '^".$search_string."'
        UNION ALL SELECT *
        FROM birf
        WHERE type REGEXP '^".$search_string."'"
        ;

$result = $tutorial_db->query($query);
    while($results = $result->fetch_array()) {
        $result_array[] = $results;
    }

    // Check If We Have Results
    if (isset($result_array)) {
        foreach ($result_array as $result) {

            // Format Output Strings And Hightlight Matches
            $display_function = preg_replace("/".$search_string."/i", "<b class='highlight'>".$search_string."</b>", $result['desc']);
            $display_name = preg_replace("/".$search_string."/i", "<b class='highlight'>".$search_string."</b>", $result['type']);
        $display_url = 'https://www.google.com/search?q='.urlencode($result['type']).'&ie=utf-8&oe=utf-8';

            // Insert Name
            $output = str_replace('nameString', $display_name, $html);

            // Insert Description
            $output = str_replace('functionString', $display_function, $output);

            // Insert URL
            $output = str_replace('urlString', $display_url, $output);



            // Output
            echo($output);
        }
    }else{

        // Format No Results Output
        $output = str_replace('urlString', 'javascript:void(0);', $html);
        $output = str_replace('nameString', '<b>No Results Found.</b>', $output);
        $output = str_replace('functionString', 'Sorry :(', $output);

        // Output
        echo($output);
    }
}

Answer 3

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";
        }
      } 
    }
  }
}

If any cell in a row contains the searched phrase or word, this function shows that row otherwise hides it.

    <input type="text" class="search-table"/>  
     $(document).on("keyup",".search-table", function () {
                var value = $(this).val();
                $("table tr").each(function (index) {
                    $row = $(this);
                    $row.show();
                    if (index !== 0 && value) {
                        var found = false;
                        $row.find("td").each(function () {
                            var cell = $(this).text();
                            if (cell.indexOf(value.toLowerCase()) >= 0) {
                                found = true;
                                return;
                            } 
                        });
                        if (found === true) {
                            $row.show();
                        }
                        else {
                            $row.hide();
                        }
                    }
          });
   });

Answer 5

$("#search").on("keyup", function() {
        var value = $(this).val().toLowerCase();
        $("tbody tr").filter(function() {
            $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
        });
    });

Assumption there is a one table with a tbody. you can also search with find or if the table has an ID you can use the id

Answer 6

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);
    });
});
