Hide tabs if content is empty - html

Question

I am creating a shop using prestashop.
My problem is, in product description I have two bootstrap tabs
<ul class="nav nav-tabs">
<li class="active"><a data-toggle="tab" href="#op">One</a></li>
<li><a data-toggle="tab" href="#conf">Spec</a></li>
</ul>
The first one is general description and the other one is more technical.
But not every product has that second description, so the content is empty.
My question is, how can i make only first tab visible when there is need to?
EDIT:
Guys I don't know if I wrote that straight.
I need tab to be hidden when the div content it 'points' on is empty.
Thanks

Answer 1

Add a class inside your second tab,and run this Jquery
$(".someclass").each(function(){
var $txt=$(this).text();
if($txt==""){
$(this).closest('li').hide();
}
})

Answer 2

This should to it:
$('.nav-tabs li').each(function () {
$tab = $(this)
if ($tab.text() === '') {
$tab.hide()
}
}

Answer 3

Maybe it's too late! But i write my answer here to help somebody.
I had a nav-tab like this with bootstrap that i wanted to hide the tabs with no content:
<ul class="nav nav-tabs" role="tablist" id="descriptionTab">
<li class="active">
introduction
</li>
<li>
access
</li>
<li>
times
</li>
</ul>
<!-- Tab panes -->
<div class="tab-content" style="position:relative;">
<div class="tab-pane fade active in EmptyFind" id="introduction">
<h2>some text here</h2>
</div>
<div class="tab-pane fade EmptyFind" id="access">
<h2>some text here</h2>
</div>
<div class="tab-pane fade EmptyFind" id="times">
<h2> <!-- no content or some whitespace --> </h2>
</div>
</div>
So we can add these lines of jquery code to hide "#times" tab that has no content in it:
<script>
$(document).ready(function() {
$('.EmptyFind').each(function() {
var $txt=$(this).text().trim().length;
var $dataTarget=$(this).attr('id');
if ($txt < 1) {
$('#descriptionTab a[href="#' + $dataTarget + '"]').closest('li').hide();
}
});
});
</script>
I hope it will be helpfull :)
