I've encountered a rather strange issue with our site's top navigation bar when viewed on an iPad. When a user taps on the "Brands" link, a drop-down menu should be shown, but it is not.
When a user taps on the "Departments" link the corresponding drop-down menu is shown properly and if the user subsequently taps on the "Brands" link the drop-down menu displays properly.
These drop-down menus are controlled via CSS class toggles triggered on hover by jQuery. When a user who hasn't previously tapped on the "Departments" link taps on the "Brands" link the class is applied correctly, however the styles aren't applied in a way that's visible to the user. I have verified this with the device emulator in Xcode as well as by debugging an iPad plugged in to my machine.
Additionally, on certain pages of the site , the drop-downs seem to work fine. I'm at a loss, I can't see what's going on here and I hope someone might point me in the right direction.
<style>
.tab {
position: absolute;
left: 0;
height: 0;
overflow: hidden;
display: block;
visibility: hidden;
margin: 1px 0 0 0;
background: #efefef;
background: rgba(255,255,255,0.95);
opacity: 0;
transition: 0.2s;
}
.drop.active .tab {
visibility: visible;
z-index: 20;
height: auto;
overflow: visible;
opacity: 1;
}
</style>
<nav id="nav" class="sixteen columns main-menu new">
<ul id="tab-nav" class="new-nav">

</nav>
<script>
// Tab Nav Toggle
$(document).ready(function(){
if ( viewWidth > 767 && is_touch_device() ) {
$('.main-menu li.drop').hover(
function() {
$(this).find('a').first().click(function(e) {
e.preventDefault();
});
$(this).toggleClass('active');
}
);
} else if ( viewWidth > 767 &! is_touch_device() ) {
$('.main-menu li.drop').hover(
function() {
$(this).toggleClass('active');
}
);
}
});
</script>
I took another look and the issue doesn't seem to have anything to do with the javascript side of things. I tested again on my iPad with Javascript disabled (I have the effect applied with :hover as a no-js fallback) and the same weird behaviour persists. The "Brands" menu doesn't work until after you've tapped on the "Departments menu.
Okay, it's not precisely clear what you're trying to do, but I think I get the gist, and I'll edit my answer as we go.
First, viewWidth
is not defined here, and so can't be used, and is_touch_device()
is not, to the best of my knowledge, a jQuery method.
Second, if you're targeting mobile devices, I'm guessing you want to fire these events when the window width is LESS THAN 767px
? If so, you've got the wrong operator. Take a look at this slightly modified and cleaned up version of your function, and take a look at the fiddle (linked below), and let me know if that's what you're after:
$(document).ready(function(){
$('li.drop').hover(function() {
var width = $(window).width();
if ( width <= 596 ) {
$(this).toggleClass('active');
$('.tab').text("The parent list of the link whose text reads, '" + $(this).find('a').text() + "' now has the class, '" + $(this).attr('class') + "'.");
}
});
$('li.drop').find('a').click(function(e) {
e.preventDefault();
alert("You have clicked the '" + $(this).text() + "' link.");
});
});
A couple things to note:
I changed our target width to 596 because that's the default width of the JSFiddle window. I used your .tab
container as sort of a console to keep track of the class toggles. I used alerts to let you know the click function is working properly.
