How to use the slice method in jquery

The slice() method selects a subset of elements based on the index.

A subset is a set that is part of a larger set.

This method is used to limit the selection of elements in the combination by the start point and end point: the start parameter is the starting index of creating the subset (starting from 0), and the stop parameter is an optional end point.

Syntax

$(selector).slice(start,stop)

Parameter Description

start Required. Specifies the position at which to start selecting elements. Index numbers start from 0. Note: If it is a negative number, it indicates that the elements are selected from the end of the selected element, rather than from the beginning.
stop Optional. Specifies the position at which selected elements end. If omitted, the selection ends at the end of the collection. Index numbers start from 0. Note: If it is a negative number, it indicates that the elements are selected from the end of the selected element, rather than from the beginning.

The example is as follows:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>123</title>
<script src="js/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$("p").slice(2).css("background-color","yellow");
});
</script>
</head>

<p>Donald Duck (下标 1)。</p>
<p>我住在 Duckburg (下标index 2)。</p>
<p>我最好的朋友是 Mickey (下标 3)。</p>
