Creating a Sort Function
Step 1: Create index.html file and implement below code in it.
<button class="btn btn-success" onclick="sortTable()">Sort</button>
<table id="Table">
<tr>
<th>ID</th>
<th>Name</th>
</tr>
<tr>
<td>5</td>
<td>Berglunds snabbkop</td>
</tr>
<tr>
<td>3</td>
<td>North/South</td>
</tr>
<tr>
<td>6</td>
<td>Alfreds Futterkiste</td>
</tr>
<tr>
<td>2</td>
<td>Koniglich Essen</td>
</tr>
<tr>
<td>1</td>
<td>Magazzini Alimentari Riuniti</td>
</tr>
<tr>
<td>7</td>
<td>Paris specialites</td>
</tr>
<tr>
<td>4</td>
<td>Island Trading</td>
</tr>
</table>
<style>
h1 {
color: red;
}
table {
border-spacing: 0;
width: 100%;
border: 1px solid #ddd;
}
th, td {
text-align: left;
padding: 13px;
}
tr:nth-child(even) {
background-color: #f2f2f2
}
</style>
<script>
function sortTable() {
var table, rows, switching, i, x, y, shouldSwitch;
table = document.getElementById("Table");
switching = true;
/*Make a loop that will continue until
no switching has been done:*/
while (switching) {
//start by saying: no switching is done:
switching = false;
rows = table.rows;
/*Loop through all table rows (except the
first, which contains table headers):*/
for (i = 1; i < (rows.length - 1); i++) {
//start by saying there should be no switching:
shouldSwitch = false;
/*Get the two elements you want to compare,
one from current row and one from the next:*/
x = rows[i].getElementsByTagName("TD")[0];
y = rows[i + 1].getElementsByTagName("TD")[0];
//check if the two rows should switch place:
if (Number(x.innerHTML) > Number(y.innerHTML)) {
//if so, mark as a switch and break the loop:
shouldSwitch = true;
break;
}
}
if (shouldSwitch) {
/*If a switch has been marked, make the switch
and mark that a switch has been done:*/
rows[i].parentNode.insertBefore(rows[i + 1], rows[i]);
switching = true;
}
}
}
</script>
