Jquery Order by Specific Order

When dealing with sorting elements using jQuery, the default order is often from ascending to descending or vice versa. However, there are cases when a specific order is required. In this tutorial, we will explore how to order items in jQuery using a specific order.

Method 1: Using an Array

One way to order items in jQuery using a specific order is by defining an array that contains the desired order. We can then sort the elements based on their position in the array.

var specificOrder = ['first', 'second', 'third', 'fourth', 'fifth'];
$('.my-elements').sort(function(a, b) {
  return specificOrder.indexOf(a.id) - specificOrder.indexOf(b.id);
});

In the code above, we define an array called specificOrder that contains the desired order. Then, we select all elements with class my-elements and sort them based on their position in the specificOrder array. We use the indexOf() method to get the index of each element's id in the specificOrder array and subtract them to determine their position compared to each other.

Method 2: Using Data Attributes

Another way to order items in jQuery using a specific order is by defining a data-order attribute that contains the desired order. We can then sort the elements based on their data-order value.

<div class="my-elements" data-order="second">Element 2</div>
<div class="my-elements" data-order="fourth">Element 4</div>
<div class="my-elements" data-order="first">Element 1</div>
<div class="my-elements" data-order="fifth">Element 5</div>
<div class="my-elements" data-order="third">Element 3</div>

$('.my-elements').sort(function(a, b) {
  return $(a).data('order') > $(b).data('order');
});

In the code above, we define a data-order attribute for each element that contains the desired order. Then, we select all elements with class my-elements and sort them based on their data-order value using the data() method in jQuery.

Conclusion

In this tutorial, we explored two ways to order items in jQuery using a specific order. The first method involved using an array that contains the desired order, while the second method involved defining a data-order attribute for each element. By using these methods, we can easily sort elements in a specific order using jQuery.
