JQuery on click <li> interference

Ok, the problem is a little hard to explain but I'll do my best.
when I click on one <li> element everyone else inside him is clicked.
I try to create categories and subcategories.but whenever I click on a category a subcategory is also called!
<li class="has-sub product_type" id="category1"> <a>Lorem1</a>
<ul>
<li class="product_sub_type" id="subcategory1"><a>Lorem2</a></li>
<li class="product_sub_type" id="subcategory2"><a>Lorem2</a></li>
<li class="product_sub_type" id="subcategory3"><a>Lorem2</a></li>
<li class="product_sub_type" id="subcategory4"><a>Lorem2</a></li>
</ul>
</li>
$(document).ready(function(){
var type_id = '';
$(".all_products").fadeOut("fast");
$(".product_type").on("click", function(event) {
alert("Dbg");
type_id = event.currentTarget.id;
$(".big_categoryes").fadeOut("fast");
$(".all_products").fadeIn("smooth");
sortProducts(type_id);
});
var type_sub_id = '';
$(".product_sub_type").on("click", function(event) {
type_sub_id = event.currentTarget.id;
sortSubProducts(type_sub_id);
});
});

JQUERY getting ID value of LI element from nested ul

HTML code
<ul id='orgCat'>
<li parent-id="0" li-id="16">Anthropology Department</li>
<li parent-id="16" li-id="18">Anthropology Faculty Collections</li>
<li parent-id="16" li-id="23">Shared Collections</li>
<li parent-id="0" li-id="19">Center for Research on Vermont</li>
<li parent-id="19" li-id="24">Collections for Testing</li>
<li parent-id="24" li-id="25">Geology Department</li>
</ul>
Jquery
jQuery(function($){
var $ul = $('ul');
$ul.find('li[parent-id]').each(function () {
$ul.find('li[parent-id=' + $(this).attr('li-id') + ']').wrapAll('<ul />').parent().appendTo(this)
});
});
//to get li-id on double click
$('#orgCat li').dblclick(function(){
alert($(this).attr('li-id'));
})
Problem is
When double click on 'li' element its showing parents 'li-id' also but it should return only current list 'li-id'. Jsfiddle

You need to use e.stopPropagation to stop event bubbling.
$('#orgCat li').dblclick(function(e){
e.stopPropagation();
alert($(this).attr('li-id'));
});

Displaying selection text in span

So let's say I have this code:
<span id="select_list">
<ul>
<li><a id="1">1</a></li>
<li><a id="2">2</a></li>
<li><a id="3">3</a></li>
</ul>
</span>
<span id="selection"></span>
And let's also assume that there are a lot of list elements, ex. '4,5,6,7... etc'.
Can I get a html file, that is basically just text, that corresponds to the list element's ID (ex. 1.html, 2.html,... etc), to show in 'selection'?
If so how?
Thanks for your time. Hope I explained it well.

Something like this (jQuery) should work:
var list = $("#select_list");
var sel = $("#selection");
$("a", list).on("click", function(){
var id = $(this).attr("id");
sel.load(id+".html");
});

<div id="select_list">
<ul>
<li id="1">1</li>
<li id="2">2</li>
<li id="3">3</li>
</ul>
</div>
<div id="selection"></div>
i would use a div not span spans are for if you want to change the size of something particular like this:
<li id="1" href="#"><a href="#"><span style="color: red;
font-size: 30px">1</span></a></li>
and from what i am understanding you want a selector to select them in css?
if so this is how:
#select_list ul li:nth_child(1) {
}
or
#select_list ul li#2 {
}
hope this helps you

I would suggest using data-attributes instead of IDs.
HTML
<ul class='selection-list'>
<li data-name='Dog'>Dog</li>
<li data-name='cat.html'>Cat</li>
<li data-name='45'>Fourty Five</li>
<li data-name='Triangle'>Three sides</li>
</ul>
<div class="output js-output"></div>
jQuery
var $output = $('.js-output');
$('.selection-list li').on('click', function() {
var selectionValue = $(this).data('name');
$output.text(selectionValue);
});
CSS
.selection-list li {
cursor: pointer;
}

iframe
I'm starting to think that you are asking for an iframe with dynamic source. The question is unclear. You may want to try and rewrite it. - Here is what I think you may be after...
HTML
<ul class='selection-list'>
<li data-url='http://reputable.agency'>Reputable Agency</li>
<li data-url='http://perpetual.education'>Perpetual Education</li>
<li data-url='http://example.com/index.html'>Example.com</li>
</ul>
<iframe src='http://example.com' class="output js-output"></iframe>
JavaScript / jQuery
var $output = $('.js-output');
$('.selection-list li').on('click', function() {
// get the 'data-url' from the element...
var selectionValue = $(this).data('url');
// put that data-url into the src attribute of the iFrame
$output.attr('src', selectionValue);
});
Also..
Note that if you are using the same domain for all of these, you can build those urls differently to keep things simple.
<li data-url='index.html'>Example.com</li>
$output.attr('src', 'http://yoursite.com/' + selectionValue);
jsFiddle
AJAX
Now I'm wondering if you mean AJAX. Here is an example - but it's not tested because I don't have access to a bunch of relative URLs - but here is the basics - and should lead you to the right documentation.
HTML
<ul class='selection-list'>
<li data-url='index.html'>Reputable Agency</li>
<li data-url='index.html'>Perpetual Education</li>
<li data-url='index.html'>Example.com</li>
</ul>
<div class="output js-output"></div>
JavaScript / jQuery
var $output = $('.js-output');
var getOtherPage = function(target) {
$.ajax({
url: target,
success:function(response){
$output.html(response);
},error:function(){
alert("error");
}
});
};
$('.selection-list li').on('click', function() {
var selectionValue = $(this).data('url');
getOtherPage(selectionValue);
});

How to save HTML ul-li structure into javascript object

i have this following html structure usilg ul and li.
<ul class="treeview" id="productTree">
<li class="collapsable lastCollapsable">
<div class="hitarea collapsable-hitarea lastCollapsable-hitarea"></div>
<span id="top1" class="">top1</span>
<ul>
<li class="collapsable lastCollapsable">
<span class="">mod1</span>
<ul>
<li class="last">
<span>bottom1</span>
</li>
</ul>
</li>
</ul>
</li>
<li class="collapsable lastCollapsable">
<span id="top2" class="">top2</span>
<ul>
<li class="collapsable lastCollapsable">
<span class="">mid2</span>
<ul>
<li class="last">
<span>bottom2</span>
</li>
</ul>
</li>
</ul>
</li>
</ul>
the website allows user to add more data under this structure and am using jquery treeview to show the tree structure dynamically.
Now i need to save this whole ul-li structure into a js object for future use in the website. how do i achieve this? the last node("bottom1 and bottom2 here") has a class "last" if that helps.
as we can add data dynamically we can be sure how much levels of ul li is there at the end when user clicks "save"

You can use recursive function to save a tree object;
function save(obj_ul, tree){
var obj_lis = obj_ul.find("li")
if (obj_lis.length == 0) return;
obj_lis.each(function(){
var $this = $(this);
if($this.parent("ul").get(0) == obj_ul.get(0))
{
tree.push({
name : $this.find('> span').text(),
child : save($this.find("ul").first(), [])
});
}
});
return tree;
}
console.log(save($('#productTree'), []));

If you want to reprouce the same thing verbatim, as a string of HTML elsewhere on the site, you could just do this? Then .append() or .prepend() treeview where you like.
​var treeview = $('#productTree').parent().html()

Assuming you want JSON:
function save(){
var tmp = [];
$('#productTree li.collapsable').each(function(){
var $this = $(this),
$spans = $this.find('span'),
o = [];
$spans.each(function(){
o.push($(this).text())
})
tmp.push(o);
});
return tmp;
}
You could also use map() to accomplish the same thing, too.
EDIT: Updated, assuming your text will live inside a span. This will create an array of arrays, each containing the text from the spans inside each of your list-items.

:not() in various guises isn't working

I'm making a simple jQuery navigation system but I am far from expert at it, as the following code may demonsytrate..
HTML:
<ul id="main-nav">
<li>HOME</li>
<li class="pipe">|</li>
<li id="about">ABOUT US</li>
<li class="pipe">|</li>
<li id="projects">PROJECT TYPES</li>
<li class="pipe">|</li>
<li id="reducing">REDUCING EMISSIONS</li>
<li class="pipe">|</li>
<li id="carbon">CARBON MARKETS</li>
<li class="pipe">|</li>
<li id="FAQs">FAQs</li>
</ul>
jQuery:
$(function () {
$("#main-nav li:not('.pipe')").hover(function () {
var $this = $(this).attr("id");
$('#nav-strip2 ul.sub-nav').hide();
$("#nav-" + $this).show();
});
});
The showing/hiding works just fine, the only issue is when the pipe is hovered over it hides everything. There's a reason the menu needs to be made up in <li>s and can't just be <a>s but it's not really relevant and long.
I'm trying here to exclude the .hover() stuff from happening when it's a li with .pipe class but there's no joy. What am I doing wrong? Any help appreciated. I'm sure there's a way of excluding <li>s with no ID attached, which would save assigning the .pipe class to all those <li>s. Alas I have not the jQuery ability to figure this out yet!
Thanks.

When using :not() as a selector, don't use quotes within its brackets:
$("#main-nav li:not(.pipe)")

try this:
$(function () {
$("#main-nav li").not('.pipe').mouseenter(function () {
$('#nav-strip2 ul.sub-nav').hide();
$("#nav-" + this.id).show();
});
});
