Changes to the element's text breaks it's parent delegated event handlers

I'm working on a drop down menu as part of a school project. I've gotten most everything to work properly but I ran into an issue with JQuery events that I couldn't quite find the answer to, whenever I click on my list item it sets the list name properly but after that none of the events work. I put the handlers on parent elements to see if that helped but still nothing.
Here's a quick look at the JQuery.
$(document).ready(function(){
$('nav ul').on('mouseenter', '.menu1', function(){
$('.menu1 ul').removeClass("hidden");
});
$('nav ul').on('mouseleave', '.menu1', function(){
setTimeout(function(){
$('.menu1 ul').addClass("hidden");
}, 300);
});
$('nav ul').on('click', '.menu1 ul li', function(){
$('.menu1').text($(this).text());
});
});
I have a code pen for the list as well.
https://codepen.io/JFarenci/pen/gvoQvq

The issue is in $('.menu1').text($(this).text());
After this line gets executed on choosing an option, the portion inside the li tag changes to this: <li class="menu1">one</li> (assuming you had chosen 'one'). The ul tag along with the dropdown menu is overwritten.
To fix this, have a separate space to display the selected option above the li tag.
HTML:
<p id="selected"></p>
JAVASCRIPT:
$('nav ul').on('click', '.menu1 ul li',function({
$('#selected').text($(this).text());
});
Hope this helps!

I removed your mouseenter and mouseleave events and replaced it with mouseover.
On each click I added a span containing $(this).text(). Note that it's preceded by a remove() to handle for prior clicks when the text was set.
See runnable snippet to test.
$(document).ready(function() {
$('nav ul').on('mouseover', '.menu1', function() {
setTimeout(function() {
$('.menu1 ul').show();
}, 300);
});
$('nav ul').on('click', '.menu1 ul li', function() {
$('.menu1').find("#click").remove();
$('.menu1').append('<span id="click">' + $(this).text() + '<span>');
});
});

ToggleClass animate with jQuery?

I have a section on my website that when a user clicks I would like it to expand, I'm using the jQuery's toggleClass for this
jQuery('.menux').click(function() {
jQuery(this).toggleClass('is-active');
jQuery('.a').toggleClass('a1');
jQuery('.b').toggleClass('b1');
jQuery('.c').toggleClass('c1');
});
When clicked, the animation runs perfectly. But when I clicked the second time, the animation does not appear. different when clicked the first time, the animation runs slowly down. When i using jQuery('.c').toggleClass('c1', 2000); <-- duration,
Not work!. How do I use animation in clicks a second time? In order to ascend slowly upwards
This my test https://jsfiddle.net/u6aztsgt/1/

Try creating a new animation and toggle that on second click or vice versa.
You can use this css for the second click animation,
#-webkit-keyframes dropUp{from{margin-top: 0px;opacity: 1}to{margin-top: -20px;opacity: 0}}
#-moz-keyframes dropUp{from{margin-top: 0px;opacity: 1}to{margin-top: -20px;opacity: 0}}
#keyframes dropUp{from{margin-top: 0px;opacity: 1}to{margin-top: -20px;opacity: 0}}
.a2, .b2, .c2 {
-webkit-animation: dropUp 1s;
-moz-animation: dropUp 1s;
animation: dropUp 1s;
-webkit-animation-fill-mode: both;
-moz-animation-fill-mode: both;
animation-fill-mode: both;
opacity: 0;
display: block;
}
.a2 {
-webkit-animation-delay: 0s;
-moz-animation-delay: 0s;
animation-delay: 0s;
}
.b2 {
-webkit-animation-delay: 0.5s;
-moz-animation-delay: 0.5s;
animation-delay: 0.5s;
}
.c2 {
-webkit-animation-delay: 1s;
-moz-animation-delay: 1s;
animation-delay: 1s;
}

CSS3 animations working in every browser except Chrome

Everything works perfectly in all browsers except Chrome. The fade in effects seems to work fine but the floatInCommand animation stutters and makes the Commend (a bootstrap container) lock in place after 1 second. I don't know if I need to add anything else besides "-webkit". I have looked at threads with similar problems and they all fix it by adding "-webkit".
.slide-in {
-webkit-animation-name: floatInCommend;
-webkit-animation-duration: 2s;
-webkit-animation-fill-mode: both; /* Safari 4.0 - 8.0 */
-moz-animation-fill-mode: both;
animation-fill-mode: both;
-webkit-animation-direction: normal;
-webkit-animation-delay: 1.25s;
}
#-webkit-keyframes floatInCommend {
from {
opacity: 0;
top: -100%;
}
to {
opacity: 1;
top: 75;
}
}
.slide-in-footer {
-webkit-animation-name: floatInFooter;
-webkit-animation-duration: 2s;
animation-fill-mode: both;
-webkit-animation-fill-mode: both; /* Safari 4.0 - 8.0 */
-moz-animation-fill-mode: both;
-webkit-animation-direction: normal;
-webkit-animation-delay: 0.5s;
}
#-webkit-keyframes floatInFooter {
from {
opacity: 0;
}
to {
opacity: 1;
}
}
.slide-in-nav {
-webkit-animation-name: floatInFooter;
-webkit-animation-duration: 2s;
animation-fill-mode: both;
-webkit-animation-fill-mode: both; /* Safari 4.0 - 8.0 */
-moz-animation-fill-mode: both;
-webkit-animation-direction: normal;
-webkit-animation-delay: 0.5s;
}
#-webkit-keyframes floatInNav {
from {
opacity: 0;
}
to {
opacity: 1;
}
}

You need both the -webkit, -moz, and non vendor prefix attributes. Consider using a task runner and an autoprefixer to make sure you have all css vendor prefixes in place before publishing your code.

Select an element and apply animation to child

I am trying to select an element, add hover to it, then have it select the child of that element. So, in this case, the hover should select the div and apply the animation to the p nested inside of it.
I have looked around on the w3schools website. I thought adding the :only-child selector might work, but it doesn't seem to. Perhaps that is not a valid syntax.
If possible, I would like to keep this CSS if possible, but perhaps it needs jquery. Does anyone know how to do this? Any input is appreciated.

/*****Display P in Drop Down*****/
#-webkit-keyframes displayP {

}

#dropDown1:hover .dropP {
Should do the trick. The .dropP specifies the element with class dropP that is a child of #dropDown1 when #dropDown1 is being hovered.

Hover somewhere below Home to see the text showing :)
You need to add prefixes for all vendors in you keyframes for this to work properly .
Change your css like this
.dropP{
opacity: 0;
}
#dropDown1:hover .dropP {
-webkit-animation-name: displayP;
-webkit-animation-duration: .12s;
-webkit-animation-delay: 1s;

On my site i have use JqUERY for a show and hide function, my addClass and RemoveClass works however overall the function isn't working how it should do. Can someone guide me in the right direction.

Add following css and HTML tag .

CSS code:-
.animated {
-webkit-animation-duration: 1s;
animation-duration: 1s;
-webkit-animation-fill-mode: both;
animation-fill-mode: both;

#keyframes fadeInUp {

}
to {
opacity: 1;
-webkit-transform: none;
transform: none;
}
}
.fadeInUp {
-webkit-animation-name: fadeInUp;
animation-name: fadeInUp;
}

Try using the css classes that you have provided, and pass a second parameter to the "addClass" call indicating the number of milliseconds that it should animate. For example:
$(".trigger").hover(function(){
var $this = $(this);
$this.next(".overlay").addClass("fadeInDown", 1000);
});
