Unable to jQuery list item when passing with parent div in selector

I have a div which has a ul and list items in it.
<div class="col-md-2"><input id="jackSerachBox" class="form-control input-md m-t-sm" type="text" placeholder="Search for Jacks.."></div>
<div class="col-md-2">
<ul class="nav nav-pills nav-stacked" id="jacksTab">
<li role="presentation" class="active">
<a data-toggle="tab" class="dd-handle">
<input type="checkbox" id="JackcheckBox-3" name="selectedjacks" value="3">
<label class="text-muted text-uppercase small">NEW40206 </label> <span><i class="fa fa-hdd-o text-info small"></i></span>
</a>
</li>
<li role="presentation" class="">
<a data-toggle="tab" class="dd-handle">
<input type="checkbox" id="JackcheckBox-6" name="selectedjacks" value="6">
<label class="text-muted text-uppercase small">NewJack12 </label> <span><i class="fa fa-hdd-o text-info small"></i></span>
</a>
</li>
<li role="presentation" class="">
<a data-toggle="tab" class="dd-handle">
<input type="checkbox" id="JackcheckBox-4" name="selectedjacks" value="4">
<label class="text-muted text-uppercase small">Jack12 </label> <span><i class="fa fa-hdd-o text-info small"></i></span>
</a>
</li>
</ul>
</div>
I am trying to access it using :
$('#jackSerachBox').on('keyup', function (e) {
var input, filter, ul, li, a, i;
// filter = input.val().toUpperCase();
li = $('#jacksTab li');
li.each(function (e) {
a = $('a', $(e)).eq(0);
console.log(a.html())
//test.html(a.html())
})
})
But getting undefined. I did ask similar question , but that was answered with the context. To be fair , had marked that as answer and did not post follow ups on that.
To be more accurate this time here is the jsfiddle for same.

Simply use this inside your .each instead of using a parameter :
If you don't want to use this, you need to edit your .each() parameters to .each(_, e), since the first parameter from the callback is the index of the element.
See the jQuery#each documentation
$('#jackSerachBox').on('keyup', function(e) {
$('#jacksTab li').each(function() {
console.log($('a', this).html())
});
})

How to get selected elements from a ul?

I've created a form and a part of this form is a list which has five elements. These elements can be hovered by mouse. The hovered elements have class of selected. The question is how can I take the value of this elements in order to send it to server?
<ul id="service" class="icon-group booking-item-rating-stars">
<li id="1">
<i class="fa fa-smile-o"></i>
</li>
<li id="2">
<i class="fa fa-smile-o"></i>
</li>
<li id="3">
<i class="fa fa-smile-o"></i>
</li>
<li id="4">
<i class="fa fa-smile-o"></i>
</li>
<li id="5">
<i class="fa fa-smile-o"></i>
</li>
</ul>

If I understand you correct this is what you need:
$('#service li').on('hover', function() {
sendToServer($(this).text());
});
And if you need to check selected class:
$('#service li').on('hover', function() {
var $this = $(this);
if ($this.hasClass('selected')) {
sendToServer($this.text());
}
});

Try this demo, if your <li> looks like this:
<li>
<input type="hidden" id="3" value="3">
<i class="fa fa-smile-o">c</i></li>
<li>
demo:
$(function() {
$('#service li').hover(function() {
$(this).addClass('selected'); // add selected class on hover
var data = $(this).find(':hidden').val(); // get input hidden value inside the li
sendToServer(data); // call send to server function passing data variable
}, function() {
$(this).removeClass('selected');
});
});
function sendToServer(data) {
console.log(data);
// insert send to server program here
}
.selected {
color: red;
}

<li>
<input type="hidden" id="3" value="3">

<li>
<input type="hidden" id="4" value="4">

If you use php rendering and on menu item click page refreshes, you can add class for example "active" to parent li(s), and in styles add li.active {display:block} or something like that style to show hidden elements

Finally i am ok with the condition of laravel routes
<li #if(Request::path() == "mypage_v2/applications/lists" || Request::path() == "mypage_v2/applications/register") class="active opened")#endif>

Jquery accordion collapsed on page load

Fiddle Here
This is because you have this first accordian open when loading it. To fix it, do a click operation on this at the time of load with $($('#accordion .expand-icon')[0]).click();. Check the working example here http://www.bootply.com/vGoKbvfKtl

you are just displaying all the accordions when the page gets loaded since there is no hiding any where.
According to your code Since only the first Accordion contains the data, it is getting displayed else every expandable div will get displayed.
The solution for this is to add a hide class to the class accordion so that it does not display at the beginning, the at the time of click function, you can remove that class and it gets displayed.
$(document).ready(function(){
$('.expand-icon').click(function(){
$('ul').removeClass('hide')
var elem = $(this);
if(elem.hasClass('active')) {
elem.removeClass('active');
var subElem = elem.siblings('ul');
var nestedElem =elem.siblings('ul').find('ul');
if(nestedElem.length == 0) {
subElem.slideUp('fast');
}
else {
nestedElem.slideUp('fast',function(){
subElem.slideUp('fast');
});
}
$.when(elem.removeClass('glyphicon-minus')).then(function(){
elem.addClass('glyphicon-plus');
});
}
else {
elem.addClass('active');
elem.siblings('ul').slideDown('fast',function(){
elem.siblings('ul').find('ul').slideDown('fast');
});
$.when(elem.removeClass('glyphicon-plus')).then(function(){
elem.addClass('glyphicon-minus');
});
}
});
$('.expandable :checkbox').on('change', function() {
$(this).parent().find('li input[type=checkbox]').prop('checked', $(this).is(':checked'));
var sibs = false;
$(this).closest('ul').children('li').each(function () {
if($('input[type=checkbox]', this).is(':checked')) sibs=true;
});
$(this).parents('ul').siblings(':checkbox').prop('checked', sibs);

<a> Links in a sidebar aren't clickable when Javascript is present

I have a sidebar on my new website that toggles sections open and closed, and it does this.
However in any browser, only when the JS script is present, I can no longer actually click the inside links.
Also, there are no errors in the console.
Please can you help me, i'm out of ideas :)
Here is the JS,
(function($) {
"use strict";
$.fn.tree = function() {
return this.each(function() {
var btn = $(this).children("a").first();
var menu = $(this).children("ul").first();
var isActive = $(this).hasClass('active');
//initialize already active menus
if (isActive) {
menu.show();
btn.children(".fa-angle-left").first().removeClass("fa-angle-left").addClass("fa-angle-down");
}
//Slide open or close the menu on link click
btn.click(function(e) {
e.preventDefault();
if (isActive) {
//Slide up to close menu
menu.slideUp();
isActive = false;
btn.children(".fa-angle-down").first().removeClass("fa-angle-down").addClass("fa-angle-left");
btn.parent("li").removeClass("active");
} else {
//Slide down to open menu
menu.slideDown();
isActive = true;
btn.children(".fa-angle-left").first().removeClass("fa-angle-left").addClass("fa-angle-down");
btn.parent("li").addClass("active");
}
});
/* Add margins to submenu elements to give it a tree look */
menu.find("li > a").each(function() {
var pad = parseInt($(this).css("margin-left")) + 10;
$(this).css({"margin-left": pad + "px"});
});
});
};
}(jQuery));
$('<i class="fa fa-angle-left pull-right"></i>').appendTo('.nav-left > li > a');
/* Sidebar tree view */
$(".sidebar .nav-left li").tree();
And this is the HTML:
<!-- Left side column. contains the logo and sidebar -->
<aside class="left-side sidebar-offcanvas">
<!-- sidebar: style can be found in sidebar.less -->
<section class="sidebar">
<!-- Sidebar user panel -->
<div class="user-panel">

Thanks for you're time, I would post a link to the real thing, but it seems that is not praised on here...

Within your loop you're setting e.preventDefault() on each link's click event, preventing the click from doing anything:
var btn = $(this).children("a").first();
...
btn.click(function(e) {
e.preventDefault();

You're calling this on every single a element within your .nav-left list. I don't really know what your desired result is, but if you remove that the links will now function as normal, but the page will change and your click function will have no effect on the new page.
Edit: From comments:
Would you be able to adapt it so that when a parent <a> that doesn't have a <ul> inside is clicked, the link works, and when the parent <a> does have a <ul>, the e.preventDefault(); is enforced on the parent <a>?
Yes, simply add a check around the click function to see whether the a element has a ul element next to it:
if (btn.next('ul').length) {
btn.click(function(e) {
...
}
}
