}

$(".subject").click(function(){

$(this).siblings().children('ul').slideUp();
});

or
$(".subject").click(function () {
$(this).find("#item").slideToggle("slow")
.end().siblings().children('ul').slideUp();
});

I corrected your markup. Your IDs should always be unique; otherwise use classes.
$(function(){
$(".subject").click(function(){
$('ul.item').not( $(this).find('ul.item') ).slideUp("slow");
$(this).find('ul.item').slideDown('slow');
});
});

How can I get number from each id and append to another data attribute using jquery?

I have some listings.
Currently id is test_3, test_1, test_2. I need number (3,1,2) from id of each li and append this number in to another data attribute. Please check the result section. It will give you an idea about what I am expecting. Thanks
Html
<ul id="cat">
<li id="test_3">Text 3</li>
<li id="test_1">Text 1</li>
<li id="test_2">Text 2</li>
</ul>
Script
$('#cat').attr('id').split("-")[2];
Expected result
<ul id="cat">
<li id="test_3" data-id="3">Text 3</li>
<li id="test_1" data-id="1">Text 1</li>
<li id="test_2" data-id="2">Text 2</li>
</ul>
To achieve this you can loop over the li elements and set the data() based on the number in the id attribute. Try this:
$('#cat li').each(function() {
$(this).data('id', this.id.split('_')[1]);
}).click(function() {
console.log($(this).data('id'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="cat">
<li id="test_3">Text 3</li>
<li id="test_1">Text 1</li>
<li id="test_2">Text 2</li>
</ul>
You can loop through all of the children of the ul element with the id cat.
On each loop, get the ID by getting the id attribute, splitting it on _ and getting the first index.
You can then set the attribute by using JQuery's attribute function, which you can learn more about here.
$('#cat li').each(function () {
var dataId = $(this).attr('id').split('_')[1];
$(this).attr('data-id', dataId);
});
An example of this in action
$('#cat li').each(function () {
var dataId = $(this).attr('id').split('_')[1];
$(this).attr('data-id', dataId);
});
console.log($('#cat').html());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="cat">
<li id="test_3">Text 3</li>
<li id="test_1">Text 1</li>
<li id="test_2">Text 2</li>
</ul>
This should some your problem.
Using $(this).attr("id").split('_') will split "cat_3" into "cat" and "3" then using [1] after will select "3"
$("#cat li").each(function(){
$(this).attr("data-id", $(this).attr("id").split('_')[1]);
})
console.log($("#cat").html())
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="cat">
<li id="test_3">Text 3</li>
<li id="test_1">Text 1</li>
<li id="test_2">Text 2</li>
</ul>
You can also use a RegExpression.
var suffix = "test_2".match(/\d+/); // results --> 2
Basically it fetches out numeric value within a string value.
Usage
$('#cat li').each(function() {
$(this).data('id', this.id.match(/\d+/));
})

jquery onclick parent remove child action

Actually I'm really very sorry about my question, I'm not sure how to make attention or ask question about this kind of problem.
Please see my code 1st.
<div data-model="ABC123" id="product">Select a Product</div>
<ul id="lists">
<li data-product="P1">Product 1
<ul id="sublists">
<li data-item="it1">P1 Item 1</li>
<li data-item="it2">P1 Item 2</li>
<li data-item="it3">P1 Item 3</li>
<li data-item="it4">P1 Item 4</li>
</ul>
</li>
<li data-product="P2">Product 2
<ul>
<li data-item="it1">P2 Item 1</li>
<li data-item="it2">P2 Item 2</li>
<li data-item="it3">P2 Item 3</li>
<li data-item="it4">P2 Item 4</li>
</ul>
</li>
<li data-product="P3">Product 3</li>
<li data-product="P4">Product 4</li>
</ul>
<div id="codes">
<span class="code1"></span>
<span class="code2"></span>
<span class="code3"></span>
</div>
The jquery code is:
<script>$('#product').click(function () {
var pmodel = $(this).data('model');
$('.code1').empty().append(pmodel);
$('.code2').empty();
$('.code3').empty();
});
$('#lists li').click(function () {
var dmodel = $(this).data('product');
$('.code2').empty().append(dmodel);
});
$('#lists li ul li').click(function () {
var item = $(this).data('item');
$('.code3').empty().append(item);
});</script>
You may directly view this at http://codepen.io/alshedupur/pen/YqKGqV
Everything is work fine, but my problem is, when I trigger parent list item like: Product 1 / Product 2 / Product 3
In result I want to empty .code3 span
I try to use $('.code3').empty(); on 2nd action but if I use this, then 3rd action I mean sub list click function not work.
Please see my screenshot for clearly understand what I want:
You need to empty .code3 as well.
$('#product').click(function() {
var pmodel = $(this).data('model');
$('.code1').empty().append(pmodel);
$('.code2').empty();
$('.code3').empty();
});
$('#lists > li').click(function(e) {
e.stopPropagation();
var dmodel = $(this).data('product');
$('.code2').empty().append(dmodel);
$('.code3').empty();
});
$('#lists li ul li').click(function(e) {
e.stopPropagation();
var item = $(this).data('item');
var dmodel = $(this).parents("li").data('product');
$('.code2').empty().append(dmodel);
$('.code3').empty().append(item);
});
#product:hover,
li:hover {
cursor: pointer
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div data-model="ABC123" id="product">Select a Product</div>
<ul id="lists">
<li data-product="P1">Product 1
<ul id="sublists">
<li data-item="it1">P1 Item 1</li>
<li data-item="it2">P1 Item 2</li>
<li data-item="it3">P1 Item 3</li>
<li data-item="it4">P1 Item 4</li>
</ul>
</li>
<li data-product="P2">Product 2
<ul>
<li data-item="it1">P2 Item 1</li>
<li data-item="it2">P2 Item 2</li>
<li data-item="it3">P2 Item 3</li>
<li data-item="it4">P2 Item 4</li>
</ul>
</li>
<li data-product="P3">Product 3</li>
<li data-product="P4">Product 4</li>
</ul>
<div id="codes">

Hide/ show list items when clicking on h4 in .aspx page

I'm building a newsletter archive which is sorted in different categories. The markup looks like this:
<h4>Category 1</h4>
<ul>
<li>Newsletter 1</li>
<li>Newsletter 2</li>
<li>Newsletter 3</li>
</ul>
<h4>Category 2</h4>
<ul>
<li>Newsletter 1</li>
<li>Newsletter 2</li>
<li>Newsletter 3</li>
</ul>
Now there will be quite a lot of categories and newsletters so I want the newsletters to be hidden until the user clicks on the Category h4. And to hide again when clicked again.
I've tried this function:
<script type="text/javascript">
$('h4').click(function() {
$(this).find('ul').toggle();
});
</script>
I guess this isn't working because I would have to wrap the h4 in a ul but this results in an error. Any suggestions?
You need to use the jQuery .next function, so it will look for the next <ul> class after each h4 tag here is a quick demo demo:
(function( $ ) {
$('h4').click(function() {
$(this).next('ul').toggle();
});
}).apply( this, [ jQuery ]);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<h4>Category 1</h4>
<ul>
<li>Newsletter 1</li>
<li>Newsletter 2</li>
<li>Newsletter 3</li>
</ul>
<h4>Category 2</h4>
<ul>
<li>Newsletter 1</li>
<li>Newsletter 2</li>
<li>Newsletter 3</li>
</ul>

HTML List Tags - how to give each <li> diffrent color from other?

how to give each <li> different color from other on Html
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<ul>
so, Iam looking to Display Items as the Following:
Item 1 In red color
item 2 In blue color
item 3 In green color
What is the best way to do it ?
Create different classes like this in css
.redText
{
color:red;
}
.blueText
{
color:blue;
}
.greenText
{
color:green;
}
And then in your html
<ul>
<li class = "redText">Item 1</li>
<li class = "blueText" >Item 2</li>
<li class = "greenText">Item 3</li>
<ul>
<ul>
JSFIDDLE DEMO
Try style component for each list.
<ul>
<li style="color:red">Item 1</li>
<li style="color:blue">Item 2</li>
<li style="color:green">Item 3</li>
</ul>

Filtering content (jQuery)

HTML:
<div class="filter">
category 1
category 2
</div>
<ul class="items">
<li class="category-1">item 1</li>
<li class="category-1">item 2</li>
<li class="category-2">item 3</li>
<li class="category-2">item 4</li>
</ul>
What I want is for example clicking on 'category 1' link should hide all other category items from the list.
I understand jQuery's .filter() selector can be used but I'm not sure how to implement it for my purpose here.
Thanks for your help!
$('div.filter').delegate('a', 'click', function (event) {
$('ul.items li').hide().filter('.' + this.href.slice(this.href.indexOf("#") + 1)).show();
event.preventDefault();
});
Basically you'll be doing something like this: $('.items li').hide(); $('.category-1').show();
The first to hide all other menu items, the latter to show the selected ones :)
You can simply put it in the onclick of the <a> tag.
