Редактирование Скопированный контент Ползунок для работы

Question

Я скопировал ползунок контента и попытался заставить его работать. Может ли кто-нибудь помочь мне заставить его работать? Благодарю.

Что мне нужно, когда вы нажимаете кнопку next, next2, next3, он отображает выделенный текст, как показано ниже.

     Sample Text 
     On a recent trip to Moab, Utah, I noticed someone wearing an Elevate foot brace, he had one on both legs. I asked him about the braces and he told me how happy he was with them. He gave me the contact information where he had purchased them from. 

     I ordered one when I returned to Seattle. I have been using the standard in the shoe straps to the calf type of brace. I didnt wear it often because it wasn't easy to put on and it was uncomfortable. It was also hard to drive with the brace on. I use the brace on my right leg, with the brace being stiff it makes it difficult to push the accelerator. With the Elevate I just release the tension on the brace and can push the accelerator with no issues. The Elevate brace is comfortable and easy to put on, I love it.

Вот способ сделать слайдер контента с минимальным JavaScript. Число <a> s должно совпадать с числом <div class="content"> s.

$(function() { 
 
    $('.slider nav a').on('click', function() { 
 
    show_content($(this).index()); 
 
    }); 
 
    
 
    show_content(0); 
 

 
    function show_content(index) { 
 
    // Make the content visible 
 
    $('.slider .content.visible').removeClass('visible'); 
 
    $('.slider .content:nth-of-type(' + (index + 1) + ')').addClass('visible'); 
 

 
    // Set the tab to selected 
 
    $('.slider nav a.selected').removeClass('selected'); 
 
    $('.slider nav a:nth-of-type(' + (index + 1) + ')').addClass('selected'); 
 
    } 
 
});
