Toggle only when parent list items is clicked

I have a simple ol li based list which toggles when i click on parent item or child item. I want it to toggle only when parent item is clicked.
$("#expList > li").click(function () {
$(this).find("ol").slideToggle();
});
https://jsfiddle.net/k2jqqbbk/3/
I tried to target it with $("#expList ol li") but this is not working. I tried few other options which didn't work either.

You could use the event.target to check whether its closest li contains an ol, and only toggle if it does:
$('#expList > li').click(function(evt) {
if ($(evt.target).closest('li').has('ol').length) {
$(this).find("ol").slideToggle();
}
});
Here's a fiddle

You need to target the a tag. Because the ol is the next child, the find call has been replaced with a call to next:
$("#expList > li > a").click(function () {
$(this).next().slideToggle();
});
If you want the functionality to extend to children of children, just omit #expList from the selector:
$("li > a").click(function () {
$(this).next().slideToggle();
});
Fiddle

Try to add the following code :
$("#expList > li").click(function () {
$(this).find("ol").slideToggle();
});
$("#expList > li ol li").click(function () {
return false;
});

The click event bubbles up to ancestor elements. So the click is fired first against the second-level list items, then bubbles up to the first-level list items. This is why you're seeing the toggling happen.
All you need to do is stop the click event bubbling up the element chain from the second-level list items.
Add this to fix:
$("#expList ol li").click(function(e) {
e.stopPropagation();
});

How can I use jQuery to toggle between 2 classes?

I am not sure toggleClass is the best way to do this, but I have a accordion menu and I am attempting to alternate the icon/image on the right side from a RIGHT arrow to a DOWN arrow.
The first click on the 3 menu items shows the DOWN image (.icon-03) but when I switch between the accordion items it does not go back to the RIGHT arrow image/class (.icon-04).
thoughts?
/* Accordion */
$(document).ready(function () {
$('#accordionFAQ > li > a').click(function(e){
if ($(this).attr('class') != 'active'){
$('#accordionFAQ li ul').slideUp();
$(this).next().slideToggle();
$('#accordionFAQ li a').removeClass('active');
$(this).addClass('active');
//add down arrow
$('> span', this).toggleClass('icon-03 icon-04');
//prevent page reload
e.preventDefault();
}
});
});
Demo JS Fiddle: http://jsfiddle.net/957Fs/

First of all, $(this).attr('class') != 'active' is very inefficient (and possibly fails to work altogether), use $(this).hasClass('active') instead.
After your comment, I re-added the classes - the following should work:
$('#accordionFAQ > li > a').click(function(e){
if (! $(this).hasClass('active') ){
$('.active')
.find('span').toggleClass('icon-03 icon-04')
.end().removeClass('active')
.next().slideUp();
$(this).find('span').toggleClass('icon-03 icon-04')
.end().addClass('active')
.next().slideDown();
//prevent page reload
e.preventDefault();
}
});

When I look at the JSFiddle example it works for me, so I guess it's updated already. I'd like to make a suggestion though: it's perhaps a good idea to just toggle a class (e.g. 'is-active') on your list items and handle the rest with pure CSS. For example:
var $faq = $('#accordionFAQ');
$faq.on('click', '> li > a', function (event) {
$(this).parent().toggleClass('is-active');
});
In your CSS you could do something like this:
#accordionFAQ > li > a span {
// width, height etc
background-position: x y;
}
#accordionFAQ > li.is-active > a span {
background-position: x y;
}
Just an idea; hope it's helpfull.

/* Accordion */
$(document).ready(function () {
var accordionFAQ = $('#accordionFAQ');
// let's use jQuery's .on() rather than .click()
accordionFAQ.find('a').on({
click:function(e){
// prevent the default action
e.preventDefault();
// setup some variables
var that = $(this);
// close open ULs
accordionFAQ.find('ul').slideUp();
// remove .active from other controller
accordionFAQ.find('.active').removeClass('active');
// add .active to clicked controller and show UL
that.addClass('active').next().slideDown();
// remove .right from span
accordionFAQ.find('.right').removeClass('right');
// add .right to current controller's span
that.find('span').addClass('right');
}
});
});
Then, you can have span's default image be the left arrow. and when you add a .right class, it will override the default image with a right arrow using CSS.
hope this helps.

JS Dropdown menu not closing?

So I found this fiddle here: http://jsfiddle.net/8qPvp/4/
I thought I'd use it just for personal education purposes.
I'm really new with JS, and I noticed that the opened parent does not go back on click, like it opens. How could this be fixed?
$(document).ready(function () {
$("li").click(function () {
$('li > ul').hide();
$(this).children("ul").toggle();
});
});

What about this:
$("li").click(function () {
$('li > ul').hide();
$(this).children("ul").toggle();
});
$(document).click(function()
{
$('li > ul:visible').hide();
})
$('.menu li').click(function(e)
{
e.stopPropagation();
})
So by default i make whenever there is clicked ANYWHERE in the document, your visible menu will be hidden. However you don't want this to happen when you open a new menu(would be; made visible and made hiden directly). So i make a exception that catch when you want to open a new menu and i'll cancel the document click event.I use event.stopPropagation() to cancel a event.
jsFiddle

$(document).ready(function () {
$("li").click(function () {
$('li > ul').hide();
$(this).children("ul").toggle();
}).mouseleave(function(){
$(this).children("ul").hide();
});
});

How to add a class onto the selected li element and make li full-sized-clickable

I want to add a class to the selected 'li' and at the same time, remove the class:selected from previous selected li element.
I have worked on it hours and still haven't got any luck. I also checked others questions, but their solutions don't work for me.
Help please....
<ul id='mainView' class='menu' style='float: left; clear: both;'>
<li>Patient</li>
<li>Recommendations</li>
</ul>
<script type="text/javascript">
$(document).ready(function () {
$('.menu ul a').on('click', function (event) {
$('.menu ul a.selected').className = '';
alert($(this).attr('id'));
$(this).attr('class') = 'selected';
});
});
// $('.menu li').on('click', function () {
// $('.menu li.selected').className = '';
// this.className = 'selected';
// });
</script>
Update:
I did put a inside li, but if I click on the li not the a inside of the li, the webpage does not redirect. That's the reason why I do it in a reversed way.
Update 2
The reason why the selected li does not get the "selected" class is because the whole webpage is redirected to a new page which has the same navigation bar.
So now the question is how to highlight the selected li(it was selected on the previous page) on the new webpage.

Inside an UL everybody (even a browser) is expecting to see a LI
so your HTML:
<ul>
<li>Patient</li>
<li>Recommendations</li>
</ul>
And your jQ:
$('ul li').click(function(){
$(this).addClass('selected').siblings().removeClass('selected');
});
Building web pages you should know how to treat LI elements. Simple, like dummy containers with minimal styling.
That means that you rather add a display:block ... float:left and other cool stuff to the <A> elements, than setting a padding there you go with your full-sized-clickable A elements.
Additionally (if you don't have time to play with CSS) to make a LI fully clickable use:
$('ul li').click(function(){
var goTo = $(this).find('a').attr('href');
window.location = goTo ;
// $(this).addClass('selected').siblings().removeClass('selected'); // than you don't need this :D
});
After the OP late edit - and to answer the question
After the pages refreshes to get which one is the active one use:
// ABSOLUTE PATH
var currentPage = window.location;
// RELATIVE PATH
// var currentPage = window.location.pathname;
$('li a[href="'+ currentPage +'"]').addClass('selected');

<script type="text/javascript">
$(document).ready(function () {
$('.menu ul a').on('click', function (event) {
$('.menu ul a.selected').removeClass('selected');
alert($(this).attr('id'));
$(this).addClass('selected')
});
});
</script>

Try addClass and removeClass, they're jQuery functions:
$(document).ready(function () {
$('.menu ul a').on('click', function (event) {
$('.menu ul a.selected').removeClass("selected");
$(this).addClass('selected');
});
});

Dropdown menus on iPhone

So I have some dropdown menus, and I listen for the touchstart event to show them, but the problem is that I don't know when to close them, since I have 2 dropdown menus on the page the problem is that..if a user clicks on a dropdown menu and I display it and after that clicks on another...that gets displayed to.
$(document).ready(function() {
$('nav ul li.sub-menu > a,nav ul li.sub-menu2 > a').bind( "touchstart",function(){
$(this).parent().find('ul').toggle();
$(this).parent().addClass('active_page');
});
});
Any ideas how to close it, when it's best to close it? :-?

The solution was to add an overlay div with position absolute.
$(document).ready(function() {
$('nav ul li.sub-menu > a,nav ul li.sub-menu2 > a').click(function(){
$(this).parent().find('ul').toggle();
$('body').prepend('<div class="overlay" />');
$('.overlay').css({'width' : $('body').css('width'), 'height' : $('body').css('height')});
$(this).parent().addClass('active_page');
return false;
});
$('.overlay').live('touchstart',function(){
$(this).remove();
$('.drop').each(function(){
if($(this).find('ul').css('display') == 'block')
{
$(this).find('ul').toggle();
}
});
//$('nav ul li.sub-menu2 > ul,nav ul li.sub-menu > ul').toggle();
return false;
});
});
