How to show content from the specific div with javascript/jQuery

I want to show content from the specific div when the page loads. This is my code:
$(document).ready(function () {
$('.pbox:gt(0)').hide();
$('#buttons').on('click', 'a', function () {
$('.current').not($(this).closest('li').addClass('current')).removeClass('current');
$('.pbox:visible').hide(600);
$('.pbox[id=' + $(this).attr('data-id') + ']').show(600);
});
});
.current {
background-color:red
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<ul id="buttons">
<li>
<a data-id="div1">One</a>
</li>
<li>
<a data-id="div2">Two</a>
</li>
<li>
<a data-id="div3">Three</a>
</li>
<li class="current">
<a data-id="div4">Four</a>
</li>
</ul>
<div class="pbox" id="div1">
Content 1
</div>
<div class="pbox" id="div2">
Content 2
</div>
<div class="pbox" id="div3">
Content 3
</div>
<div class="pbox" id="div4">
Content 4
</div>
As you can see by default am adding the current class to the element:
<li class="current">
<a data-id="div4">Four</a>
</li>
So what am trying to achieve is when the page loads show Content 4 as you can see right now it shows Content 1 when the page loads.
Can anybody try to help me with this?

If you need show content where link is active you can do it with code below
$.fn.pageLoad = function() {
const currentId = $('li.current>a').data('id');
$('.pbox:visible').hide(600);
$('.pbox[id=' + currentId + ']').show(600);
}
$('document').pageLoad();
Just make any load function which close all pboxes and find current li>a id and open it. Also you can add setTimeout if your content is loading slow.

If handlebars list is empty, show a message

I am using handlebars to show data. I have a ul that filters the data and populates another ul. The filter ul has a couple of choices that currently output an empty ul. I want the empty ul to show a message that says "There are no sessions yet."
I am trying to use handlebars if helper. The problem I am running into is the message is showing up in all ul, even if it is not empty.
<div class="session-details-inner">
<div class="sidebar left-sidebar left-align">
<ul id="session_filter_15308050681959955093" class="session_filters no-list-style">
<li>
<a class="themelink active" data-filter="All" title="All Tracks">General</a>
</li>
<li>
<a class="themelink" data-filter="Destination Marketers" title="Destination Marketers">Destination Marketers</a>
</li>
<li>
<a class="themelink" data-filter="Exhibitions" title="Exhibitions">Exhibitions</a>
</li>
<li>
<a class="themelink" data-filter="Financials" title="Financials">Financials</a>
</li>
<li>
<a class="themelink" data-filter="Registration" title="Registration">Registration</a>
</li>
<li>
<a class="themelink" data-filter="Technical" title="Technical">Technical</a>
</li>
<li>
<a class="themelink" data-filter="Venues" title="Venues">Venues</a>
</li>
</ul>
</div>
<div class="sidebar right-sidebar left-align">
<ul class="scheduleday_wrapper themeborder no-list-style">
{{#each ./Sessions}}
{{#if TrackDescription.length}}
<li class="themeborder individual-session accordion-panel" data-track="{{TrackDescription}}">
<div class="session_content_wrapper expandable accordion">
<div class="session_content ">
<div class="session_title">
<h6>{{Title}}</h6>
</div>
</div>
</div>
<div class="session_content_extend hide session_content_wrapper panel">
<div class="session_content ">
<div class="session_excerpt">{{SessionDetails}}</div>
<div class="session_title_list">
<span class="ti-bookmark"></span>
<div class="session_title_item">{{TrackDescription}}</div>
</div>
</div>
</div>
</li>
{{else}}
<li class="no-sessions">There are no session yet.</li>
{{/if}}
{{/each}}
</ul>
</div>
<script type='text/javascript'>
$(document).ready(function($) {
$('.accordion').on('click', function() {
$parent_box = $(this).closest('.accordion-panel');
//$parent_box.siblings().find('.panel').slideUp(500);
$parent_box.siblings().find('.icon').removeClass('down');
$parent_box.find('.panel').slideToggle(500);
$parent_box.find('.icon').toggleClass('down');
});
$('ul.scheduleday_wrapper li .session_content_wrapper').on('click', function(ev) {
    ev.preventDefault();
    jQuery(this).next().toggleClass('hide');
});
$(".session_filters a").click(function(){
jQuery(".session_filters a").removeClass("active");
jQuery(this).addClass("active");
currentSessionType=jQuery(this).attr("data-filter");
jQuery(".individual-session").hide();
jQuery(".individual-session[data-track='"+currentSessionType+"'").show();
individualSession = jQuery('.individual-session');
if(currentSessionType == 'All'){
jQuery(".individual-session").show();
}
});
});
</script>

If you want to check & conditionally render if there are no sessions, shouldn't you do the length check on your Sessions instead of the TrackDescription?

Added this snippet of jQuery to check if all li had a style of display: none. If all li have display: none, show message li else hide message li.
if($('.scheduleday_wrapper').children(':visible').length == 0){
jQuery(".no-sessions").show();
}
else{
jQuery(".no-sessions").hide();
}

How to retrieve some text from a sibling div element in jQuery

I have some divs on a page in this order as below. When someone clicks a link inside the UL .list-links I want to capture the value of
<span class="asa_portlet_title">Title here</span>
in a variable. I've tried using siblings and closest but it always returns empty.
--
<div class="my_portlet" style="display:none;">
<span class="asa_portlet_title">Title here</span>
</div>
<div class="links">
<div class="">
<ul class="list-links">
<li class="margin-bottom-medium">
Link name
Link name
Link name
Link name
</li>
</ul>
</div>
</div>
--
$('[ul.list-links a').click(function() {
var _portletTitle = $(this).siblings('.my_portlet').text();
});
Open to pure javascript method as well. Basically I have a number of divs on the page containing links, and those divs have another div above it where the title exists
Would anyone be able to put together a small working sample?

You are not trying to get the siblings, you are trying to get the sibling of the parent .links of this.
Also you have to prevent the default action of the a element. You can do that by calling preventDefault() on the event object.
$('ul.list-links a').click(function(event) {
event.preventDefault();
var _portletTitle = $(this).closest('.links').prev('.my_portlet').text();
console.log(_portletTitle);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="my_portlet" style="display:none;">
<span class="asa_portlet_title">Title here</span>
</div>
<div class="links">
<div class="">
<ul class="list-links">
<li class="margin-bottom-medium">
Link name
Link name
Link name
Link name
</li>
</ul>
</div>
</div>
<div class="my_portlet" style="display:none;">
<span class="asa_portlet_title">Title here 2</span>
</div>
<div class="links">
<div class="">
<ul class="list-links">
<li class="margin-bottom-medium">
Link name 2
Link name 2
Link name 2
Link name 2
</li>
</ul>
</div>
</div>

How to show and hide a section?

I want to show the div of selected HTML link.
For example:
I clicked on the html link Categories the <div id="categories" ... > will be showed and the other div's will hide.
HTML
<div id="col-navigation">
<ul>
<li>
Quizzes
</li>
<li>
Categories
</li>
<li>
Jump
</li>
</ul>
</div>
<div id="quizzes"> //default showed
Quizzes!
</div>
<div id="categories" style="display:none">
Categories!
</div>
<div id="jump" style="display:none">
Jump!
</div>

Try this:-
$('#col-navigation a').click(function(){
$('#quizzes,#categories,#jump').hide();
$('#' + $.trim($(this).text()).toLowerCase()).show();
});
Fiddle
OR
$('#col-navigation a').click(function(){
$('#quizzes,#categories,#jump').show()
.not('#' + $.trim($(this).text()).toLowerCase()).hide();
});
Fiddle

$("#col-navigation a").click(function(e) {
var getText = $(this).text().trim().toLowerCase();
$("#"+getText).toggle().siblings().hide();
e.preventDefault();
});
use the above code to make it work.
Working Fiddle : https://jsfiddle.net/z4bprass/1/

You can use css :target, general siblings selector ~
:target {
display: block !important;
}
:target ~ div[id] {
display: none;
}
<div id="col-navigation">
<ul>
<li>
Quizzes
</li>
<li>
Categories
</li>
<li>
Jump
</li>
</ul>
</div>
<div>
<div id="categories" style="display:none">
Categories!
</div>
<div id="jump" style="display:none">
Jump!
</div>
<div id="quizzes">//default showed Quizzes!
</div>
</div>

Show first div on page load and hide others and then show the rest on click of the menu items

I am working on a menu where on click of the navigation items, the div will be shown, but by default, the first div should be shown and rest hidden. They should be seen only on click of other navigation items.
Below is my code that I have tried so far.
The HTML:
<ul id="menu">
<li class="page_item current_page_item justClick">a</li>
<li class="page_item page-item-2 justClick">b</li>
<li class="page_item page-item-2 justClick">c</li>
<li class="page_item page-item-2 justClick">d</li>
<li class="page_item page-item-2 justClick">e</li>
<li class="page_item page-item-2 justClick">f</li>
<li class="page_item page-item-2 justClick">g</li>
<li class="page_item page-item-2 justClick">h</li>
<li class="page_item page-item-2 justClick">i</li>
</ul>
<div class="content">
</div>
<div class="content1">
cccc1
</div>
<div class="content2">
cccc2
</div>
<div class="content3">
cccc3
</div>
<div class="content4">
cccc4
</div>
<div class="content5">
cccc5
</div>
<div class="content6">
cccc6
</div>
<div class="content7">
cccc7
</div>
<div class="content8">
cccc8
</div>
<div class="content9">
cccc9
</div>
The Script:
$('.justClick').bind('click', function() {
$('div.content').html($('div.content' + ($(this).index()+1)).html());
});
The CSS:
.content {
background-color: red;
}
The JSFiddle link:
http://jsfiddle.net/6uzU6/
I am getting to achieve the onclick functionality on the click of navigation items on click of them, but all the div's are visible.
What I want, is that all the div's except first div (with the class .content) should be hidden and when you click on the navigation items, it should show up.

Try this:
$('div').not(".content,.content1").hide();
$('.justClick').bind('click', function() {
$('div').not(".content").hide();
$('div.content').html($('div.content' + ($(this).index()+1)).html());
});
DEMO

It seems like there is something missing in your code because there is no relation between the links and div you want to show. you will require more attributes on to maintain a relations between them.
A better approach would be apply a common class to all div like 'content-block' and class equal to use following code.
$(".content-block:not(:first)").hide();
and show respective div on click on link
$("#menu li").click(function(e){
$(".content-block").eq($(this).index()).show();
});
you can use other parameters as well to relate them instead of index.

Give attribute to div runat="server" and Id="dv1"
using property display block and none u can show or hide it
