Question

Attempting to apply .hover to a class that shows a div based on a dynamic ID. For example:

HTML

<div id="parent_one">
    <div class="touch" id="one">Touch me!</div>
    <div id="t_one"></div>
</div>
<div id="parent_two">
    <div class="touch" id="two">Touch me!</div>
    <div id="t_two"></div>
</div>

jQuery

$('.touch').hover(
    function(){
        var id = $(this).attr('id');
        var value = '#t_' + id;
        $(value).fadeIn(800);
    },
    function(){
        var id = $(this).attr('id');
        var value = '#t_' + id;
        $(value).delay(1500).fadeOut(800);
    }
);

I have a feeling my mistake is in the use of $(this) but can’t nail it down.

Answer 1

This:

var value = 't_' + id;

Needs to include #:

var value = '#t_' + id;

Otherwise you are just selecting for an element with the tag t_one, which is not an existing tag name.

However using ids for this is pretty ugly. If you have consistent HTML like this, why not use a class structure like this:

<div>
  <div class="touch-handle">Touch me!</div>
  <div class="content"></div>
</div>

with JS like this:

$('.touch-handle').hover(
  function(){
    $(this).next('.content').fadeIn(800);
  },
  function(){
    $(this).next('.content').delay(1500).fadeOut(800);
  }
);
