Trigger next submit button

Question

I am having problem with selecting the next submit button via jQuery.

I have something like this:

 $('.description-part').on('change', 'textarea', function() { $(this).find('.button').addClass('test'); // not working $(this).next('.button').addClass('test'); // not working $(this).closest('.button').addClass('test'); // not working }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="description-part"> ... <textarea></textarea> <div></div> <input type="submit" name="save" class="button"> ... </div> 

Answer 1

Just use the nextAll() as the this is textarea and not div and you have a <div> in between the textarea and button , so .next() won't work either:

$('.description-part').on('change', 'textarea', function() {
    $(this).nextAll('.button').addClass('test');
});

Or you can use .closest() this way:

$('.description-part').on('change', 'textarea', function() {
    $(this).closest('.description-part').find('.button').addClass('test');
});

Working Snippet

 $(function() { $('.description-part').on('change', 'textarea', function() { $(this).closest('.description-part').find('.button').addClass('test'); }); }); 

 .test {background: red;} 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="description-part"> ... <textarea></textarea> <div></div> <input type="submit" name="save" class="button" />... </div> 

 $(function() { $('.description-part').on('change', 'textarea', function() { $(this).nextAll('.button').addClass('test'); }); }); 

 .test {background: red;} 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="description-part"> ... <textarea></textarea> <div></div> <input type="submit" name="save" class="button" />... </div>
