How To Sort Table in JavaScript

DataGrid Library may be used as a sort-only JavaScript plugin. It may sort any HTML content, including DIVs, lists, or tables. Let's see how to sort a basic table with random data.

First, let's add a minimal HTML structure:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Sort HTML Table with DataGrid Library</title>
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
</head>
<body>
</body>
</html>

Now, let's add a table with some sample data. It will contain three columns - user first name, user last name, and age. Each column has an appropriate CSS class: .age, .first-name and .last-name.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Sort HTML Table with DataGrid Library</title>
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
</head>
<body>
<table class="demo-table">
<thead>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr>
<td class="first-name">Wendye</td>
<td class="last-name">Lightwing</td>
<td class="age">24</td>
</tr>
<tr>
<td class="first-name">Milena</td>
<td class="last-name">Torre</td>
<td class="age">82</td>
</tr>
<tr>
<td class="first-name">Erinn</td>
<td class="last-name">Hills</td>
<td class="age">81</td>
</tr>
<tr>
<td class="first-name">Yoshiko</td>
<td class="last-name">Smithson</td>
<td class="age">62</td>
</tr>
<tr>
<td class="first-name">Umberto</td>
<td class="last-name">McFadden</td>
<td class="age">93</td>
</tr>
<tr>
<td class="first-name">Donaugh</td>
<td class="last-name-name">Huban</td>
<td class="age">75</td>
</tr>
<tr>
<td class="first-name">Cami</td>
<td class="last-name">Pickthorn</td>
<td class="age">45</td>
</tr>
<tr>
<td class="first-name">Alistair</td>
<td class="last-name">Reddell</td>
<td class="age">55</td>
</tr>
<tr>
<td class="first-name">Genia</td>
<td class="last-name">Crawshay</td>
<td class="age">60</td>
</tr>
<tr>
<td class="first-name">Allyn</td>
<td class="last-name">Liell</td>
<td class="age">37</td>
</tr>
</tbody>
</table>
</body>
</html>

Also, let's add some styles:

.demo-table{
margin: 2rem auto;
border: 1px solid #ddd;
border-collapse: collapse;
}
.demo-table td,
.demo-table th{
padding: 1rem;
border: 1px solid #ddd;
}
.demo-table tr:nth-child(even) td{
background: #f4f4f4;
}
select{
margin: auto;
display: block;
}

Now we need to add a DataGrid CSS to the HEAD of the document:

<!-- DataGrid library CSS -->
<link href="datagrid.min.css" rel="stylesheet" />

And additionally, we need to add the DataGrid script at the bottom of the document.

<!-- DataGrid library JavaScript -->
<script src="datagrid.min.js"></script>

All we need to do now is to define what exactly should be sorted. Let's add the data-grid attribute to the <tbody> element of the table, and data-grid-item property to each <tr> element. Now the table will look like follows:

<table class="demo-table">
<thead>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>
</tr>
</thead>
<tbody data-grid>
<tr data-grid-item>
<td class="first-name">Wendye</td>
<td class="last-name">Lightwing</td>
<td class="age">24</td>
</tr>
<tr data-grid-item>
<td class="first-name">Milena</td>
<td class="last-name">Torre</td>
<td class="age">82</td>
</tr>
<tr data-grid-item>
<td class="first-name">Erinn</td>
<td class="last-name">Hills</td>
<td class="age">81</td>
</tr>
<tr data-grid-item>
<td class="first-name">Yoshiko</td>
<td class="last-name">Smithson</td>
<td class="age">62</td>
</tr>
<tr data-grid-item>
<td class="first-name">Umberto</td>
<td class="last-name">McFadden</td>
<td class="age">93</td>
</tr>
<tr data-grid-item>
<td class="first-name">Donaugh</td>
<td class="last-name-name">Huban</td>
<td class="age">75</td>
</tr>
<tr data-grid-item>
<td class="first-name">Cami</td>
<td class="last-name">Pickthorn</td>
<td class="age">45</td>
</tr>
<tr data-grid-item>
<td class="first-name">Alistair</td>
<td class="last-name">Reddell</td>
<td class="age">55</td>
</tr>
<tr data-grid-item>
<td class="first-name">Genia</td>
<td class="last-name">Crawshay</td>
<td class="age">60</td>
</tr>
<tr data-grid-item>
<td class="first-name">Allyn</td>
<td class="last-name">Liell</td>
<td class="age">37</td>
</tr>
</tbody>
</table>

Now let's add a sort control HTML:

<select data-grid-control="sort">
<option data-path=".first-name" data-direction="asc" data-type="text" selected>Sort by first name asc</option>
<option data-path=".first-name" data-direction="desc" data-type="text">Sort by first name desc</option>
<option data-path=".last-name" data-direction="asc" data-type="text">Sort by last name asc</option>
<option data-path=".last-name" data-direction="desc" data-type="text">Sort by last name desc</option>
<option data-path=".age" data-direction="asc" data-type="number">Sort by age asc</option>
<option data-path=".age" data-direction="desc" data-type="number">Sort by age desc</option>
</select>

You may find the detailed documentation of the sort dropdown control here.

The final step is to initialize the DataGrid library as follows:

<script>
datagrid();
</script>

That's all! The final HTML is:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Sort HTML Table with DataGrid Library</title>
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
<!-- Demo page styles -->
<style>
.demo-table{
margin: 2rem auto;
border: 1px solid #ddd;
border-collapse: collapse;
}
.demo-table td,
.demo-table th{
padding: 1rem;
border: 1px solid #ddd;
}
.demo-table tr:nth-child(even) td{
background: #f4f4f4;
}
select{
margin: auto;
display: block;
}
</style>
<!-- DataGrid library CSS -->
<link href="datagrid.min.css" rel="stylesheet" />
</head>
<body>
<select data-grid-control="sort">
<option data-path=".first-name" data-direction="asc" data-type="text" selected>Sort by first name asc</option>

<option data-path=".last-name" data-direction="asc" data-type="text">Sort by last name asc</option>
<option data-path=".last-name" data-direction="desc" data-type="text">Sort by last name desc</option>
<option data-path=".age" data-direction="asc" data-type="number">Sort by age asc</option>
<option data-path=".age" data-direction="desc" data-type="number">Sort by age desc</option>
</select>
<table class="demo-table">
