I am struggling with a JavaScript / jQuery issue. I am developing with foundation 4. I have a group of 5 buttons. Two of the buttons are dropdown buttons. When the dropdown button is pressed a window is presented with the dropdown options(links).
<a id="products" href="#" data-dropdown="prod" class="not_active_button_dropdown">Dropdown Button</a><br>
<ul id="prod" class="f-dropdown">
<li><a class="prod" href="index.php?info=basic">Basic</a></li>
<li><a class="prod" href="index.php?info=unifrost">Unifrost</a></li>
<li><a class="prod" href="index.php?info=teal">Teal-Sorb</a></li>
</ul>
Note: I created my own buttons classes with sass by mixin (class="not_active_button_dropdown").
Now I developed a script that loads the php response into a div #dropdownwrap, changes the buttons so it highlights the current button that has been pressed.
<script style="text/javascript">
$(document).on('click','a.not_active_button, a.prod', function(){
var href=$(this).attr('href');
var querystring=href.slice(href.indexOf('?')+1);
//get
$.get('index_jq.php', querystring, processResponse).error(errorResponse);
//reset all buttons to not active
//normal button
$('a.active_button').removeClass("active_button").addClass("not_active_button");
//dropdown button
$('a.active_button_dropdown').removeClass("active_button_dropdown").addClass("not_active_button_dropdown");
//if it is a normal button make it active
if ($(this).hasClass("not_active_button"))
{
$(this).addClass("active_button");
}
//if it is a dropdown button option link make it active
if ($(this).hasClass("prod"))
{
$('#products').removeClass("not_active_button_dropdown").addClass("active_button_dropdown");
//$('ul#prod.f-dropdown').close();
}
//slide down wrap
if ($('.dropdownwrap').is(":hidden")) {
$('.dropdownwrap').slideDown();
} else {
$('.dropdownwrap').slideToggle("slow");
$('.dropdownwrap').slideDown("slow");
}
return false; // stop the link
});
function processResponse(data) {
$('.dropdownwrap').html(data);
}
function errorResponse() {
var errorMsg = "Your request could not be processed right now.";
errorMsg += "Please try again.";
$('.dropdownwrap').html(errorMsg);
}
</script>
I am not that experienced with JavaScript or jQuery. Anyhow the problem is the following:
//$('ul#prod.f-dropdown').close();
which is mented out above. Everything works fine, my data loads and the dropdown button highlights. The problem is that the foundation 4 dropdown button window does not close after the script executes. This is because (I am guessing) I return false to stop the link from executing. So I tried to close the window using the above mented out line. When I unment the line, the window closes but the return false does not execute, that is the link is not disabled, it goes to the link, i. e. index.php?info=basic. So it seems when I add the close window statement, return false does not work. I tried adding the line after return false, but it does not close the dropdown menu.

- On further inspection the the line $('ul#prod.f-dropdown').close() is not causing the popup links to close when unmented. – user2197774 Commented Jul 26, 2013 at 14:10
- I tested a mouseleave function on the popup menu and I got a javascript error $(ul#prod.f-dropdown) does not have close method. I guess you cannot close a ul. Still trying to find a way to close popup. – user2197774 Commented Jul 26, 2013 at 14:19
- Basically, I want to prevent the link from being acted on, but still want the popup window to close which return false is preventing. – user2197774 Commented Jul 26, 2013 at 14:35

Reset to default 9The return false; not working is probably because there is some JavaScript error before it reaches that line. In this case, the error is calling .close() on something which does not have a close method. Instead, in order to call Foundation dropdown’s close method, you have to do something like the following:
$('#prod').foundation('dropdown', 'close', $('#prod'))
I guess there is a more elegant way to do this, but I found this to work. As a note, next time please post a minimal example on jsfiddle and link to it in your question. This makes reproducing your problem much easier.
You also need the data-dropdown-content attribute attached to the dropdown ul element.
