jquery slidetoggle list without list elements trigger the effect

I am quite new to everything about html/js/css. Right now i need a list so i decided to use a list that u can slidetoggle. I looked it up and found how to recreate that effect (the code below):
var subMenu = jQuery(".tableContainer ul li ul li");
var linkClick = jQuery(".tableContainer ul li").filter(":has(ul)");
linkClick.click(function () {
$(this).find('ul li').slideToggle(200);
});
(if you are wondering about the 2 ul and li, it is because i want that list in another list, but that doesn t change the question so i didn t include it in my explanation)
Since i am quite new to this topic, i only understand like 70% of what is happening. But for my project i need to work with the elements of the list(the ones which were hidden and after sliding down visible). I want to do stuff that requires clicking them like highlight on click, but now i encounter the problem, that the code i posted makes the slide effect being triggered not only by the headline, but also by the elements. So i cannot click elements without minimizing the list with the same click (obviously the elements are hidden again then). I hope you guys can explain me how to make the function only be triggered by the head object and not by the whole list element(head and the expanded list).

Look the slide effect is being triggered not only by the headline but also by the elements that are because the concept of event bubbling which basically means in case of click event if you clicked a child element the event is bubbled by default to the parent elements tree till the document level firing any registered event handler. so when you click the element you click the headline too, so you need to add another child element and handle the click on it something like this:-
<div class="tableContainer">
<ul>
<li> <span>menu 1</span>
<ul>
<li>link 1</li>
</ul>
</li>
<li><span> menu 2</span>
<ul>
<li>link 2</li>
</ul>
</li>
<li><span> menu 3</span>
<ul>
<li>link 3</li>
</ul>
</li>
<li> <span>menu 4</span>
<ul>
<li>link 4</li>
</ul>
</li>
</ul>
</div>
$(function() {
var subMenu = jQuery(".tableContainer ul li ul li");
var linkClick = jQuery(".tableContainer span");
console.log(linkClick.length);
linkClick.click(function() {
console.log('clicked');
$(this).siblings('ul').slideToggle(200);
});
});

Click element up the dom with jQuery

I have a menu and I want an element with a class of active, parent element's sibling element to be clicked automatically on page load.
Here is my HTML:
<li class="level1">
<span class="level1 drop-down clicked">Oranges</span>
<ul class="level2" style="display: block;">
<li class="level2">Peel</li>
<li class="level2">Pips</li>
<li class="level2 active">Pegs</li>
</ul>
</li>
I've tried
jQuery('li.level2.active').parent('li.level1').children('span.level1.drop-down').click();
but it does not work. I'm not sure if I'm using the parent & children method's properly.
Although, jQuery("span.drop-down.level1").click(); does work, but it selects all the elements with that class which I would like to avoid.

Try this:
jQuery('li.active').closest('li.level1').find('span.level1.drop-down').trigger('click');

Because the li.level1 is two steps up, you need .parents(), which selects up multiple levels, instead of .parent(), which is only one.
jQuery('li.level2.active').parents('li.level1').children('span.level1.drop-down').click();

Javascript variable setting - list items

I have this menu and I want to set one variable for each li item, and alert with it's text when clicked. This was easy, I solved for this with the script below.
$("ul#menudropd .animal li a").click(function() {
var whatever = $(this).text();
alert(whatever); });
Now, I also need to include the 'parent' (ie, the text in the mainlinks class) in the alert. The parent is usually never clicked, only hovered over to display the children. But, it is text so it should be easy right?
Example:
Currently, you click on "Puppy" and alert says "Puppy". I need to say "Dog : Puppy". Same for the next section. Click on "Kitten" I need the alert to come back as "Cat: Kitten".
I know how to have the alert display both once I get that 2nd variable set, I just can't figure out how to do it without clicking it. Any ideas?
<ul id="menudropdown">
<li class="mainlinks"> Dog
<div class="animal dog">
<li> Puppy </li>
<li> Pup </li>
</div>
</li>
<li class="mainlinks"> Cat
<div class="animal cat">
<li> Kitty </li>
<li> Kitten </li>
</div>
</li>
</ul>

Use closest() and you may also want ul instead of div, the html you have seems invalid as div directly contain li element.
The HTML List item element (<li>) is used to represent a list item. It
should be contained in an ordered list (), an unordered list
() or a menu (), reference.
Live Demo
Html
<ul id="menudropdown">
<li class="mainlinks"> Dog
<ul class="animal dog">
<li> Puppy
</li>
<li> Pup
</li>
</ul>
</li>
<li class="mainlinks"> Cat
<ul class="animal cat">
<li> Kitty
</li>
<li> Kitten
</li>
</ul>
</li>
</ul>
Javascript
$("ul#menudropdown .animal li a").click(function () {
alert($(this).closest('.mainlinks').find('a:first').text());
});

You should find the closest li tag with your mainlinks class and then select the text of the first child.
Like this:
$(this).child().first().text()+" : "+$(this).text();

Adding class to list with jQuery

I have nested lists and I need to style every items. Normally I would do something like this:
$('#myList li').addClass('myClass');
However, because they are nested, I need to style just text, I suppose. How do I do this with jQuery? I thied this, but it did not work:
$('#myList li').text().addClass('myClass');
Here's HTML
<ul id="myList">
<li>
item 1
</li>
<li>
item 2
<ul>
<li>
asdasd
</li>
</ul>
</li>
</ul>
I NEED TO StYLE EVERY LIST ITEM

first level, direct child
$('#myList > li').addClass('myClass');
second level AND higher
$('#myList li li').addClass('myClass');
This subject is largely documented on jquery api selector page
Now your question has been edited : you need to style ALL list items :
CSS
li { /* will affect ALL list-items */}
Now you made it clearer :
Wrapping what's inside the LI element
$('li').wrapInner( "<span class='your-css-selector'></span>" );
Now you shown that you won't search more than a copy-paste solution :
Wrapping what's inside the LI element but not what resides in another inner-element
$('#myList li').each(function(){
$(this).contents().first().wrap("<span/>")
});

You cannot just style text.
You can specifically style the nested list items by doing this:
$('ul#myList > li > ul > li').addClass('myClass');
This will add the myClass class to the item that has the text asdasd in your example

Just wrap your text in a span and apply class on them. When you apply class on li all of its contents gets impacted hence any descendants as well like nested ul under the li. Instead just wrap the texts in an element and apply class to them.
<ul id="myList">
<li>
<span>item 1</span>
</li>
<li>
<span>item 2</span>
<ul>
<li>
<span>asdasd</span>
</li>
</ul>
</li>
</ul>
and
$('#myList li > span').addClass("myClass");
With this you could just handle it using Css rule itself.

Removing parent elements and re-appending children

I have a navigation that's a unordered list, here's the simple structure I'm following / have to follow for my jQuery plugin to work correctly, therefore making this code structure a necessity:
<nav id="mp-menu" class="mp-menu">
<div class="mp-level">
<ul id="demo1" class="nav">
<li>
Devices
<div class="mp-level">
<h2>Devices</h2>
<a class="mp-back" href="#">back</a>
<ul>
<li>Mobile Phones</li>
<li>Televisions</li>
<li>Cameras</li>
</ul>
</div>
</li>
<li>
Magazines
<div class="mp-level">
<h2>Magazines</h2>
<a class="mp-back" href="#">back</a>
<ul>
<li>National Geographic</li>
<li>Scientific American</li>
</ul>
</div>
</li>
...
</ul>
</div>
</nav>
I need to provide a fallback and I have selected another jQuery plugin that needs to use a different structure to the above. I need to remove the DIV's with classname .mp-level but still keeping all unordered lists including .mp-level child lists.
The result will just be unordered lists without headings and DIV'S. My code below is removing the correct elements but my issue is with re-inserting the child unordered lists (specifically level 2):
$( "#demo1 h2, .mp-back" ).remove();
$( ".mp-level ul li .mp-level" ).detach();
$( ".mp-level ul li" ).append('.mp-level ul li .mp-level ul');
Anyone got any advice how to re-insert child UL's after I have removed their parents?

you can do this
$("#mp-menu").find(".mp-level").each(function(i,n){//each ".mp-level"
$(n).parent().append($(n).children());//append children to parent
$(n).remove();//remove actual div
});
http://jsfiddle.net/WBWwG/

You can save the detached nodes (wrapped inside a jQuery object) by assigning them to a variable and then using that variable in the .append() call.
Something like this:
// this selector doesn't select anything from the example html, btw
var $mp_level = $( ".mp-level ul li .mp-level" ).detach();
$(".mp-level ul li").append($mp_level);
