I am working with a menu structure as shown below.
$('html').removeClass('no-js');
// Add plus mark to li that have a sub menu
$('li:has("ul") > a').append('<span class="plusMark">+</span>');
Mousetrap.bind('down', function(e) {
if ($(".manu-t").children("ul").children("li").children(":focus").length != 0) {
//mentioned below What I have tried till now
}
});#nav,
#nav ul,
#nav li {
margin: 0;
padding: 0;
border: 0;
list-style: none;
box-sizing: border-box;
}
#nav {
position: relative;
min-height: 30px;
max-width: 100%;
background-color: #b5b5b5;
color: #000;
}
#nav li {
position: relative;
}

text-decoration: none;
height: 100%;
display: block;

</div>The challenge is to shift focus from Item1 to Item2 and then to Item3 by pressing the down arrow key (using Mousetrap library for keypress detection)
This is what I have attempted so far...
1.
var focused_index = 1;
focused_index=focused_index - 1;
$('a').eq(focused_index).focus();
However, this method focuses on nested elements, moving from Item1 to Sub Item 1, then Sub Item 2, and so on...
2.
// Get the focused element:
var $focused = $(':focus');
// No jQuery:
var focused = document.activeElement;
// Does the element have focus:
var hasFocus = $('foo').is(':focus');
// No jQuery:
elem === elem.ownerDocument.activeElement;
Nevertheless, this causes issues with other elements in the Body tag that have focus.
