Use of jQuery :lt() and :gt() selectors

Question

Aryan Kumar · Answer

The :lt() and :gt() selectors are jQuery selectors that can be used to select elements based on their index within a set of matched elements. The :lt() selector selects elements with an index number less than a specified number, while the :gt() selector selects elements with an index number greater than a specified number.
The index numbers start at 0, so the :lt(1) selector will select the first element in a set of matched elements, the :lt(2) selector will select the second element, and so on. The :gt(1) selector will select the second element in a set of matched elements, the :gt(2) selector will select the third element, and so on.
These selectors can be used to select specific elements within a set of matched elements, or they can be used to select a range of elements. For example, the following code will select all of the elements in a set of matched elements that have an index number less than 3:
Code snippet
$(".myClass:lt(3)")
The following code will select all of the elements in a set of matched elements that have an index number greater than 2:
Code snippet
$(".myClass:gt(2)")
These selectors can be used to perform a variety of tasks, such as hiding or showing elements, changing the style of elements, or adding event handlers to elements.
Here are some examples of how the :lt() and :gt() selectors can be used:
To hide the first two elements in a set of matched elements, you could use the following code:
Code snippet
$(".myClass:lt(2)").hide();
To change the color of all of the elements in a set of matched elements that have an index number greater than 3, you could use the following code:
Code snippet
$(".myClass:gt(3)").css("color", "red");
To add a click event handler to all of the elements in a set of matched elements that have an index number less than 5, you could use the following code:
Code snippet
$(".myClass:lt(5)").on("click", function() {
  // Do something when the element is clicked
});
