Difficulty arising while trying to access the following element after the designated target using JQuery

JSFiddle

I'm encountering a strange issue in the fiddle linked above. When typing a character into an input followed by pressing the down key, the console logs two values: one correct value of 3, and one incorrect value of 0.

The challenge is to select the element following a specific input:

// this works...
console.log($('.autocomplete li').length);
// this does not work
console.log($(this).next('.autocomplete li').length);

Even though logging $(this) returns input as expected, I have experimented with methods like .nextAll and .find without success.

What could be causing it to fail finding the .next element of the target?

Answer №1

The element with the class .autocomplete is positioned immediately next to this, not the li element. Therefore, the filter operation will not function as intended.

To resolve this issue, you should utilize 

$(this).next('.autocomplete').find('li')

Alternatively, have you explored any solutions that do not rely on JavaScript?

<input type="text" list="options" />
<datalist id="options"> <!-- ^-- Same identifier -->
  <option>America</option>
  <option>Europe</option>
  <option>Japan</option>
</datalist>

Answer №2

Here's a successful solution:

console.log($(this).next('.autocomplete').find('li').length);

To achieve this, it is important to focus on the following step: aim for the adjacent .autocomplete and locate the li.
