Use jQuery to place the initial 3 elements within a div

Currently, I am dynamically pulling content into li elements using ASP.NET. My goal is to wrap a specific div class around the first 3 li items in the list only. Here is an example:

                <ul class="wrapper">
                    <div class="recommend">
                            <li><a href="#"><img src="#" /></a></li>
                            <li><a href="#"><img src="#" /></a></li>
                            <li><a href="#"><img src="#" /></a></li>
                    </div>
                            <li><a href="#"><img src="#" /></a></li>
                            <li><a href="#"><img src="#" /></a></li>
                            <li><a href="#"><img src="#" /></a></li>
                            <li><a href="#"><img src="#" /></a></li>
                            <li><a href="#"><img src="#" /></a></li>
                </ul>

I have come across a fiddle that is close to achieving this desired result, which I have found and modified. Here is the link to the fiddle: http://jsfiddle.net/ZuK4E/. However, the fiddle applies the modification to every 3 li items instead of just the first 3. Since all lis are the same, I am unable to target any specific ones using ids.

Answer №1

Check out the live demo here!

Wrap the first three list elements inside a div with class "recommend" using the jQuery code below:

lt(3) targets the first three elements, starting from 0 (i.e. 0, 1, 2)

:lt - learn more about the :lt selector in the jQuery documentation

Answer №2

Currently implementing a temporary solution, but working on a more efficient one. In the meantime, feel free to use this code snippet :)

for (let i = 0; i < arr.length; i += 3) {
if (i < 1) {
    arr.slice(i, i + 3).wrapAll('<div class="recommended"></div>');
}
}
