What is the best way to navigate through a div element contained within another div element using jQuery

I am currently working on creating an ajax search bar using jQuery. I have encountered a roadblock where I need to navigate through dynamically created div elements within a larger div based on user input. Essentially, the divs are generated in response to JSON data and I want the ability to highlight these div elements as the user navigates using the up and down arrow keys.

<div class="comment">
      <div class="single" >
          //this div is dynamically created with the information 
      </div>
</div>

I am looking for suggestions on how to achieve this functionality efficiently. I have attempted a few approaches but they haven't been successful so far.

EDIT Here is my current implementation:

    $(document).ready(function(){ 
      $('#inputText').on('keydown',function(e){ 
      var $current=$('.comment>.single').first(); 
      $current.css('background-color','yellow'); 
      if(e.keyCode==40){ 
         var $nextDiv; 
         if($current.next().size==0){ 
            $nextDiv=$('.comment>.single').first(); 
          } 
         else
          { 
             $nextDiv=$current.next(); 
          }
          $current.css('background-color',''); 
          $nextDiv.css('background-color','yellow'); 
          $current=$nextDiv; 
         } 
      }); 
   });

Any help or advice would be greatly appreciated. Thank you!

Answer №1

It seems like there may be an issue with how you are setting your current and next div elements, as well as not providing the code for arrow down functionality.

Here is a jsFiddle link that I have created for you:

https://jsfiddle.net/fxabnk4o/1/

Additionally, make sure to check if any of your divs have a background color of yellow and traverse accordingly.

I have iterated through all elements with the class '.single', but there might be a more efficient approach.

var a = $('.single');
       for(var i = 0; i < a.length; i++)
       {
       if($(a[i]).css('backgroundColor') == "rgb(255, 255, 0)")
       {
      isFirst = false;
            $current= $(a[i]);
          break;
       }
       else{
       isFirst = true;
       $current = $('.comment > .single').first();
       }
       }

Then, based on the pressed arrow key, select the next or previous element.

if($current.next().size==0){ 
            $nextDiv=$('.comment>.single').first(); 
          } 
          if(!isFirst){
          $nextDiv=$current.next(); 
          $current.css('background-color',''); 
          $nextDiv.css('background-color','yellow'); 
          $current=$nextDiv; 
          }
          else
          {
          $current.css('background-color','yellow'); 
          }

and

 var $nextDiv; 
         if($current.prev().size==0){ 
            $nextDiv=$('.comment>.single').first(); 
          } 
          if(!isFirst){
          $nextDiv=$current.prev(); 
          $current.css('background-color',''); 
          $nextDiv.css('background-color','yellow'); 
          $current=$nextDiv; 
          }
          else
          {
          $current.css('background-color','yellow'); 
          }

$('input', $('#comment')).forEach(function () {

$('input', $('#single')).forEach(function () {

    console.log($(this)); //display each element found in the console
});

    console.log($(this)); //display each element found in the console
});
