How to get span dynamic value inside li ul

My ASPX code looks like this:
<ul id="userlist">
<a class="s-test">
<li>
<span id="userlistspan" class="tt-User" value="1">Cardiologist</span>
<span id="userlistspan1" class="tt-Userss">SPECIALITY</span>
</li>
</a>
<a class="s-test">
<li>
<span id="userlistspan" class="tt-User" value="2">Cardio</span>
<span id="userlistspan1" class="tt-Userss">SPECIALITY</span>
</li>
</a>
</ul>
The jQuery I have tried is like this:
$('#userlist li #userlistspan').click(function () {
$('#txtSearch').val($(this).text());
})
//here am getting text like Cardio
How can I get value like value=2 from that span?

Your HTML is completely invalid for several reasons:
you cannot have an a element as a direct child of a ul. The li must be the child element.
You have duplicate id attributes when the id should be unique in same document, use classes to group elements instead.
span elements do not have a value attribute, if you want to store custom data with an element, use the data-* attribute.
the a element must have either an href or name attribute, however their use in this case seems redundant so you can remove them.
You need to fix all those issues first:
<ul id="userlist">
<li>
<span class="userlistspan tt-User" data-value="1">Cardiologist</span>
<span class="userlistspan1 tt-Userss">SPECIALITY</span>
</li>
<li>
<span class="userlistspan tt-User" data-value="2">Cardio</span>
<span class="userlistspan1 tt-Userss">SPECIALITY</span>
</li>
</ul>
From there you can attach the click handler to the .userlistspan class, and use the this keyword to reference the element which raised the event. You can then use the data() method to get the data-value, like this:
$('#userlist li .userlistspan').click(function() {
var $span = $(this);
$('#txtSearch').val($span.text());
var value = $span.data('value'); // = 1 or 2, depending on which element you clicked.
})

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 get the string in div onclick attribute with jQuery?

I have a banner which is something like this:
<ul id="carousel">
<li id="item1">
<div onclick="window.open('mylinkhere.com,'_blank')" style="cursor:pointer;margin-left:-436px;width:996px;height:100%">
</div>
</li>
<li id="item2">
<div onclick="window.open('myotherlinkhere.com,'_blank')" style="cursor:pointer;margin-left:-436px;width:996px;height:100%">
</div>
</li>
</ul>
I need to access the links written in onclick attribute i.e. mylinkhere.com
I tried
var banners = $($("#carousel")[0]).children().filter("li");
var b_items = $(banners[0]).children().filter("div");
attr_val = $(".b_items")[0].attr("onclick");
But i couldn't. By the way i don't know from the start that which item will be in the carousel because it's randomized by another function. So i cannot access them with item1 item2 ect.
Thanks.

You can set the url in a data attribute and read easily like this:
<ul id="carousel">
<li id="item1">
<div data-url="mylinkhere.com" onclick="window.open($(this).data('url'),'_blank')" style="cursor:pointer;margin-left:-436px;width:996px;height:100%">
</div>
</li>
<li id="item2">
<div data-url="myotherlinkhere.com" onclick="window.open($(this).data('url'),'_blank')" style="cursor:pointer;margin-left:-436px;width:996px;height:100%">
</div>
</li>
</ul>
To read:
var b_items = $(banners[0]).children().filter("div");
var link = $(b_items).data('url');
See this fiddle:
http://jsfiddle.net/Pontual/pugytfwu/

For me, the following code works as expected (Chrome 44, jQuery 2.1.3):
var s = jQuery('#carousel li div');
s.each(function(i,node) {
alert(jQuery(node).attr('onclick'));
});

Possible problem is that in your code, you do not wrap the element into $(...), so .attr() is not a valid function, as using indexers on a jQuery object returns raw HTML elements.

How to get the value of data attribute using jquery

I am working on a node.js application which generates a html page. This html page displays a list of associates built according to the data passed onto this page. A list is built something like as follows:
<ul class="notification-body" style="">
//loop for all assocaite id's passed to this page
<li class="testClass" data-associateid="<%= assocID %>">
<span>
<span class="subject">
<label class="btnClass label label-info">ClickMe!</label>
</span>
</span>
</li>
The generated html src looks something like this:
<ul class="notification-body" style="">
<li class="testClass" data-associateid="AA01">
<li class="testClass" data-associateid="AA02">
<li class="testClass" data-associateid="AA03">
I am trying to get the value of the data attribute using Jquery & I tried the following:
$(".btnClass").click(function(){
console.log($".testClass").attr("data-associateid"));
});
But this outputs'AA01'everytime i click on the btn and I am not getting the expected output in the console:
AA01
AA02
AA03
I tried the following also but it gives me undefined:
$(".btnClass").click(function(){
console.log($(this).find(".testClass").attr("data-associateid"));
});

You need to use jQuery.data().
I've created a jsFiddle to show this working.
I've closed the LI because AR.
<ul class="notification-body" style="">
<li class="testClass" data-associateid="AA01">1</li>
<li class="testClass" data-associateid="AA02">2</li>
<li class="testClass" data-associateid="AA03">3</li>
</ul>
Here's the JavaScript:
$(document).ready(function() {
$('.testClass').on('click', function(){
alert( $(this).data('associateid') );
});
});
Anytime you have an attribute that starts with data-, you can reference the string after the dash as a data container. Here, I'm calling jQuery.data() on an object (the LI) and asking for the data in the container associateID.

What you are currently doing:
$(".btnClass").click(function(){
console.log($(".testClass").attr("data-associateid"));
});
Will match the first instance of .testClass and print the data-associateid attribute. What you seem to want to do is to iterate over all .testClass and print their data-associateid values:
$(".btnClass").click(function(){
$(".testClass").each(function() {
console.log($(this).attr('data-associateid'));
});
});
Based on your updated HTML you would do this:
$(".btnClass").click(function() {
var id = $(this).parents('.testClass').attr('data-associateid');
console.log(id);
});
This will search the parents of the clicked on .btnClass to find elements with the class .testClass.

To get the data for that instance you simply need to traverse to the parent <li>.
Within an event handler, this is the element that the event occured on. Use closest() to access the parent <li>
$(".btnClass").on('click', function(){
alert( $(this).closest('li').data('associateid') );
});

Assign different classes to your li elements like this:
<ul class="notification-body" style="">
<li class="testClass1" data-associateid="AA01">test 1</li>
<li class="testClass2" data-associateid="AA02">test 2</li>
<li class="testClass3" data-associateid="AA03">test 2</li>
</ul>
Note, that I closed your li and ul tags to have valid HTML.
And then you can select an element with its own class:
console.log($(".testClass2").attr("data-associateid"));
I created a JSFiddle for you:
http://jsfiddle.net/8rLpbk5m/

I had hoped you could do it with just a find but apparently not. You have to use each to loop through all the elements.
$(".btnClass").click(function(){
$(".testClass").each(function() {
console.log($(this).attr('data-associateid'));
});
});
View it here: http://jsfiddle.net/rt677qp5/

Using .data() is more logical in this case.
$(".btnClass").click(function() {
$(".testClass").each(function() {
alert($(this).data("associateid"));
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<ul class="notification-body" style="">
<li class="testClass" data-associateid="AA01"></li>
<li class="testClass" data-associateid="AA02"></li>
<li class="testClass" data-associateid="AA03"></li>
</ul>
<button class="btnClass"></button>

Weird behavior with .parents() and .closest() when trying to return parent <ul> element id in jQuery

So I've got 2 <ul> containers each with id's. Inside of them are a list of <li> elements.
The first <ul> is <ul id="coaches-list">. The second is <ul id="players-list">.
There are tags within each <li> that have an id called close (which is a link that I'm using as my selector), which will delete each <li> node once clicked. I'm trying to target each <ul> container to see where it is coming from.
My HTML is:
<!-- coaches box -->
<div class="box">
<div class="heading">
<h3 id="coaches-heading">Coaches</h3>
<a id="coaches" class="filter-align-right">clear all</a>
</div>
<ul id="coaches-list" class="list">
<li><span>Hue Jackson<a class="close"></a></span></li>
<li class="red"><span>Steve Mariuchi<a class="close"></a> </span></li>
</ul>
</div>
<!-- players box -->
<div class="box">
<div class="heading">
<h3 id="players-heading">Players</h3>
<a id="players" class="filter-align-right">clear all</a>
</div>
<ul id="players-list" class="list">
<li><span>Steve Young<a class="close"></a></span></li>
<li><span>Gary Plummer<a class="close"></a></span></li>
<li><span>Jerry Rice<a class="close"></a></span></li>
</ul>
</div>
My remove tag function in jQuery is:
function removeSingleTag() {
$(".close").click(function() {
var $currentId = $(".close").closest("ul").attr("id");
alert($currentId);
// find the closest li element and remove it
$(this).closest("li").fadeOut("normal", function() {
$(this).remove();
return;
});
});
}
Whenever I click on each specific tag, it's removing the proper one I clicked on, although when I'm alerting $currentId, if I have:
var $currentId = $(".close").closest("ul").attr("id");
It alerts 'coaches-list' when I'm clicking on a close selector in both <ul id="coaches-list" class="list"></ul> and <ul id="players-list" class="list"></ul>
If I change that to:
var $currentId = $(".close").parents("ul").attr("id");
It has the same behavior as above, but alerts 'players-list', instead.
So when using closest(), it's returning the very first <ul> id, but when using parents(), it's returning the very last <ul> id.
Anyone know what is going on with this whacky behavior?

It's expected behavior.
You should use:
var $currentId = $(this).closest("ul").attr("id");
$(this) points at the clicked .close.
$(".close") points at the first one found.

It's because you run that selector from click handler you should use this instead:
var $currentId = $(this).closest("ul").attr("id");

Try using this function to get the parent:
var $currentId = $(this).parents().first();
I've never used the .closest() function but according to jQuery what you have specified should work. Either way, try that out and tell me how it goes.
You also need to make it so that it selects the current element by using $(this)
