Javascript Replace innerhtml

I am having trouble replacing the html.
I want the whole "expand" div output to be replaced, as in the h3 and li texts will change according to which button the user presses.
As of now, the code does work to a point, the h3 changes, but rather than typing the actual text into my javascript, I want to be able to call the id and change it. Another problem is that pressing the prev button doesn't do anything yet. I also want the list of answers to change when clicking next.
Desired Outcome
when user clicks on next button, html is replaced with next question.
when user clicks on prev button, html is replaced with previous question.
function nextButton() {
var str = document.getElementById("expand").innerHTML;
var res = str.replace("which icon is used for GitHub?", "what is this?");
document.getElementById("expand").innerHTML = res;
}
var iconquiz = [
{
iq2: "<h3>what is this?</h3>",
ia2: "<li>this is something</li><li>this is something2</li>"
},
{
iq3: "<h3>what is next></h3>",
ia3: "<li>something</li><li>something else</li>"
}
];

I haven't done all the cleanup here, but I think you'll get the idea from what's below. Note that I gave your <h3> element an ID so now you can just replace the raw text instead of trying to insert an HTML element into there. You'll have to work through how the answers are displayed, etc.
You'll also need to check the bounds of your array (list of questions) so your index doesn't go below zero or above the max index (length minus 1).
var index = 0;
function nextButton() {
index++;
document.getElementById("questionHere").innerHTML = iconquiz[index].iq;
}
function prevButton() {
index--;
document.getElementById("questionHere").innerHTML = iconquiz[index].iq;
}
var iconquiz = [
{
iq: "question number one",
ia: "<li>this is something</li><li>this is something2</li>"
},
{
iq: "question number two",
ia: "<li>something</li><li>something else</li>"
},
{
iq: "question number three",
ia: "<li>something</li><li>something else</li>"
}
];

How to use animation with append in jQuery?

How to use animation while appending new element using jQuery? I went through couple of answers here but the same method does not work for me. I used show('show') and fadeIn('slow') but it does not seem that animates the new element.
$(document).ready(function() {
$('#add-item').click(add);
function add() {
var newItem = $('#new-item-text');
var span = $('<span>', {
class: 'remove',
click: remove
});
var li = $('<li>', {
class: 'todo-item',
text: newItem.val(),
append: span,
click: completed
});
if (newItem.val()) {
$('ul.todo-list').append(li, $('li.todo-new')).fadeIn('slow');
newItem.val('');
}
}
});
.todo-list {
list-style: none;
padding: 0px;
}
.todo-item {
border: 2px solid #444;
margin-top: -2px;
padding: 10px;
cursor: pointer;
display: block;
background-color: #ffffff;
}
.todo-new {
display: block;
margin-top: 10px;
}
.todo-new input[type='text'] {
width: 260px;
height: 22px;
border: 2px solid #444;
}
.todo-new a {
font-size: 1.5em;
color: black;
text-decoration: none;
background-color: #ffffff;
border: 2px solid #444;
display: block;
width: 24px;
float: right;
text-align: center;
}
.todo-new a:hover {
background-color: #0EB0dd;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<ul class='todo-list'>
<li class='todo-item'>4L 2% Milk
<span class='remove'></span>
</li>
<li class='todo-item'>Butter, Unsalted
<span class='remove'></span>
</li>
<li class='todo-new'>
<input id='new-item-text' type='text' />
<a id='add-item' href='#'>+</a>
</li>
</ul>

To animate, you should start by hiding the elements, for instance by setting:
display: none;
Then fadeIn() will animate and set display: block;

jQuery slide/toggle menu

Newbie in JS / jQuery here.
First problem: When page is loading or it is refreshing whole sub-sub menus are blinked for like 0.5sec so they can "hide". I have put the script firstly on the end of "body" tag, but after this blink I've put it in "head" so is there any way to make it actually hide, like really hide, to not be shown when page is on load?
Second problem is when I'm clicking on either blue or green square menu is not sliding smoothly. It's like a bounce effect. Is it because of "hide"? And last problem is with slideDown function. Where shall I use slideUp to make it go back to the position where it hides?
jQuery(document).ready(function($)
{
$(".raid ul").hide();
$(".raid").hide();
$(".wod").one("click", function()
{
$(".wod ul li").slideDown(200);
});
$(".mop").one("click", function()
{
$(".mop ul li").slideDown(200);
});
$(".hfc").click(function()
{
$(".hfc").addClass('x');
$(".hfc ul").slideToggle(200);
});
$(".soo").click(function()
{
$(".soo ul").slideToggle(200);
});
});

If you really want the elements hidden, use CSS. The CSS can have properties like
.raid ul {
display: none;
}
.raid {
display: none;
}
instead of calling the hide() function in jQuery. This way, if you include the CSS in the head section and keep your JS in the bottom, the blink would not happen (because the browser would keep them hidden by default)

Clickable drop-down menu javascript

I have used JavaScript to create 3 clickable drop-down menu button in a webpage. when I click one button, script is works well. I can see the following menu is displayed. When I another button, the following menu is displayed. however, the previous menu is still there.
Here is my script. Hope someone can help me. Thank you!
<script type="text/javascript" >
$(document).ready(function() {
$(".account").click(function() {
var X = $(this).attr('id');
if (X == 1) {
$(".submenu").hide();
$(this).attr('id', '0');
} else {
$(".submenu").show();
$(this).attr('id', '1');
}
});
//Mouse click on sub menu
$(".submenu").mouseup(function() {
return false
});
//Mouse click on my account link
$(".account").mouseup(function() {
return false
});
//Document Click
$(document).mouseup(function() {
$(".submenu").hide();
$(".account").attr('id', '');
});
});
</script>
// CSS
.dropdown
{
color:#000;
margin: 0px 22px 0 0;
width: 300px;

}

}

font-weight: bold;
padding: 6px 15px;

padding:0px;
font-size: 11px;
padding: 11px 0 0 0px;
border-top:1px solid #dedede;
}
// html
<div class="dropdown">
<a class="account" >My Account</a>
<div class="submenu">
<ul class="root">
<li ><a href="#Dashboard" >Dashboard</a></li>
<li ><a href="#Profile" >Profile</a></li>
<li >Settings</li>
<li >Send Feedback</li>
</ul>
</div>
</div>

My personal recommendation is to do this with with a combination of JS & CSS.
You should use an active class to hide and show your elements:
//JS
$('.menu a').on('click', function({
$('.menu a').removeClass('active');
$(this).addClass('active');
});
// CSS
.active .submenu {
display: block;
}

Final part of my dropdown menu

Ok so thanks to people here I have nearly completed my dropdown to the standard of a 3 year old. I know that there is probably a way to shorten and streamline my code so any pointers would be great. Here is all my code and a jsfiddle will be at the bottom:
oh and before I forget is there a way that I can smooth out the animations? like a wait() kind of deal that will make the slide down wait until the slide up is complete?

Sorry if this is coded like a moron (I'm still using my training wheels).
Thanks

For one, you should use CSS classes instead of ids for the a tags that trigger the slideToggle on their respective submenus. Also, ids in a valid HTML page are expected to be unique and you use the same id "1", "2", etc. for different elements. More importantly, though, by using classes you don't need to bind the onclick event for all the anchor tags separately, which saves a lot of code ;-)
Here is the updated Fiddle: http://jsfiddle.net/XN4vf/3/
The relevant code is this:
$("a.slide").on('click', function(e){
e.preventDefault();
$(this).parent().siblings().find("ul:visible").slideUp();
$(this).next("ul").slideToggle(300);
});
Once you give the a tags a class called "slide" or similar, you can rewrite your event callback to first hide / slideUp all the submenus belonging to the siblings of the currently clicked a tag. After that, you trigger the slideToggle() to show or hide the current submenu. That way, if you first click on ABOUT and then without clicking on ABOUT again (and triggering the toggle) you click on WORK for instance, then the submenu changes correctly.

You can try this:
$(document).ready(function () {
$('#midnav li a').on('click', function(event){
event.preventDefault();
$('#midnav li ul').slideUp(300);
var ul = $(this).parent().find('ul');
if(ul.is(':visible')){
ul.slideUp(300);
}else{
ul.slideDown(300);
}
});
});
