I have jquery in a different file located in the same map, I'm using this code below to activate the .slideToggle
function. However it's not working, why?
jQuery(document).ready(function ($) {
// get li items
var ul = document.getElementById("menu-footermenu");
var items = ul.getElementsByTagName("li");
// display 5 li items, hide others
for (var i = 0; i < items.length; ++i) {
if (i > 5) {
items[i].style.display = "none"
}
}
// when clicking on more catogories button, display all items
$('#morecat').click(function () {
for (var i = 0; i < items.length; ++i) {
if (i > 5) {
items[i].slideToggle();
document.getElementById("morecat").style.display = "none";
}
}
});
});
I'm getting the error:
Uncaught TypeError: .slideToggle is not a function
make sure, NOT to use the slim version of jquery, which excludes the effects like the animation.
Firstly ensure you're not using the 'slim' branch of jQuery as it does not include animation or AJAX functionality, amongst others. You will need to use the full version of jQuery in this instance.
In addition, items
in your code will be a collection of Element objects, not jQuery objects, hence the slideToggle()
function is not available on them.
To fix this you need to convert them:
$(items[i]).slideToggle();
Alternatively, you can convert all the logic to use jQuery, instead of the rather odd half/half solution you have now:
jQuery(function ($) {
var $ul = $("#menu-footermenu");
var $items = $("li");
$items.filter(':gt(4)').hide();
$('#morecat').click(function () {
$items.filter(':gt(4)').slideToggle();
$(this).hide();
});
});
