How can change text of title when tab bootstarp was been active?

I have a tab bootstarp and a title for my page and I want to change the title of page with click on tab is active but my jquery code donot work correctly.
$(document.body).on('click', '.chooseChangePass li a', function(e) {
if ($("#chPass").hasClass("active")) {
$("#TitlePage").html("change Password");
} else {
$("#TitlePage").html("change UserName");
}
if ($("#chUserName").hasClass("active")) {
$("#TitlePage").html("change UserName");
} else {
$("#TitlePage").html("change Password ");
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<h1 id="TitlePage">change password</h1>
<ul class="chooseChangePass">
<li class="active" id="chPass">change password</li>
<li id="chUserName">change UserName</li>
</ul>
<div class="tab-content">
<div role="tabpanel" class="tab-pane fade" id="changeUserName">
changeUserName
</div>
<div role="tabpanel" class="tab-pane fade in active" id="changePassword">
changePassword
</div>
</div>

You are missing code, that toggles active class. Add bootstrap.min.js file. Also, else statements in your code are redundant.
Correct way of changing page title after tab changes is to use Bootstrap navs events. You need to listen for shown.bs.tab event.
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
$('#page-title').html(e.target.text);
});
Here's working example with Bootstrap 4.1.3: https://codepen.io/anon/pen/OrJOQE?editors=1010
Be sure to lookup documentation for Boostrap version that you are using, as there were significant changes between version 3 and 4. And change tab selector to named one, if you are planning to have more tab groups on same page.

How to automatically direct users to second tab in window using JavaScript?

I am trying to automatically click/open Tab2 in a web page whenever Tab1 loads so that Tab2 becomes the active tab. I'm not sure what needs to happen here since there is no specific URL to direct a user to, so would appreciate any assistance and feedback.
Thanks!
.active {
background: red;
}
<div id="xy1:primaryForm:xy22:0:xy23" class="nav active">
<span id="xy1:primaryForm:xy22:0:tabSwitch">
<span id="xy1:primaryForm:xy22:0:tabSwitch.start" style="display: none">
<img src="/img/loading.png" class="loadingimg">
</span>
<span id="xy1:primaryForm:xy22:0:tabSwitch.stop"></span>
</span>
Tab1
</div>
<div id="xy1:primaryForm:xy22:1:xy23" class="nav">
<span id="xy1:primaryForm:xy22:1:tabSwitch">
<span id="xy1:primaryForm:xy22:1:tabSwitch.start" style="display: none">
<img src="/img/loading.png" class="loadingimg">
</span>
<span id="xy1:primaryForm:xy22:1:tabSwitch.stop"></span>
</span>
Tab2
</div>
---------UPDATE-------------
I tried to simplify this a bit by not paying attention to all the functions inside the link and just wanted to click on the link based on the text()..
.active {
background: red;
}
<div id="xy1:primaryForm:xy22:0:xy23" class="nav active">
<span id="xy1:primaryForm:xy22:0:tabSwitch"></span>
Tab1
</div>
<div id="xy1:primaryForm:xy22:1:xy23" class="nav ">
<span id="xy1:primaryForm:xy22:1:tabSwitch"></span>
Tab2
</div>
The following jQuery sort of works, but it continues to click on Tab2 even when Tab2 is already active, so I want to get it to only click Tab2 if Tab1 has an active class:
var elements = $('a');
elements.each(function(index, domElement) {
var $element = $(domElement);
if ($element.text() === "Tab2") {
$element.click();
return false;
}
});
Is there a better JavaScript Solution to click some text() only if it's a child of an .active class?

When clicked inside div that is toggled to show, it toggles up

I have an annoying problem, I have a button that toggles a dropdown, my intention is to hide the div when clicked on the button again, which toggle achieves, and to hide the dropdown when clicked outside why my current jquery does. However when clicking inside the div itself, it slides back up.
HTML >
<div class="navPanel">
<!-- NAV -->
<nav>
<ul id="navBar">
<div class="dynamicNav">
<div class="menu1Container">
<li class="menu1">Books
<!-- DropDown1-->
<div id="dropdownContainer-1">
</div>
</li>
</div>
</div>
</ul>
</nav>
Jquery >
$(function(){
$(".menu1").click(function(){
$("#dropdownContainer-1").slideToggle(90);
});
$(document).click(function(event) {
if (!$(event.target).is(".menu1") && !$(event.target).is(".menu1")) {
$("#dropdownContainer-1").slideUp(90); //make all inactive
}
});
});
The obvious problem is event target, I tried using a similar method ->
$(document).click(function(e) {
var target = e.target;
if (!$(target).is('.menu1') && !$(target).parents().is('.menu1')) {
$('#dropdownContainer-1').slideUp(90);
}
});
If you could help me figure this one out, I'd appreciate it!

You may use:
$(event.target).closest(".menu1").length == 0
$(".menu1").click(function(e){
e.stopPropagation(); // avoid to propagate to document click
if ($(event.target).is(".menu1")) {
$("#dropdownContainer-1").slideToggle(90);
console.log('Menu1 toggled clicking menu1');
}
});
$(document).click(function(event) {
if ($(event.target).closest(".menu1").length == 0 &&
$("#dropdownContainer-1").is(':visible')) {
// if not inside area of menu1
$("#dropdownContainer-1").slideUp(90); //make all inactive
console.log('Menu1 closed clicking outside menu1');
}
});

How to prevent named anchor jump/scroll in main page using easytabs jQuery plugin?

Here's a js fiddle to demonstrate the problem.
I have a fixed position floating/popup dialog on my page that contains a series of tabs using the easytabs jQuery plugin. When the dialog appears, any tab selection causes the webpage (behind the floating dialog) to jump/scroll to a different position on the page.
I've read in other places that forcing the click behavior of the anchor tags in the tab structure to prevent the default behavior will correct this issue, but it doesn't seem to be working for me e.g. assigning a class such as .prevent-default to each tab anchor element and doing:
$('.prevent-default').click(function(e) {
e.preventDefault();
return false;
});
Here's some html:
<h1>Top</h1><button onclick="showTabDialog();">Tabs</button>
<p id="spacer"></p>
<h1>Bottom</h1>
<div id="dialog" class="floating-dialog">
<div id="tabs" class="tab-container">
<ul class="tabs">
<li class="tab">
First
</li>
<li class="tab">
Second
</li>
</ul>
<div id="content-container">
<div id="first" class="tab-content">
<div class="tab-no-data">No data yet</div>
</div>
<div id="second" class="tab-content">
<div class="tab-no-data">No data yet</div>
</div>
</div>
</div>
</div>
...and some js:
$(document).ready(function() {
$('#tabs').easytabs({animationSpeed: 'fast'});
$('.prevent-default').click(function(e) {
e.preventDefault();
return false;
});
});
function showTabDialog() {
$('#dialog').fadeIn();
}

$('#tabs').easytabs({animationSpeed: 'fast', updateHash: false});
Demo: http://jsfiddle.net/naa22prw/3/

Another way to do this is to set a minimum height on the tabs container div. `
#tab-container{
min-height: 700px;
}
This means that you can use the updateHash: true so the URL can change each time a tab is clicked.

bootstrap tab on active changed

i have this tab in bootstrap:
<ul class="nav nav-tabs" id="feedtab">
<li class="active">Atlass</li>
<li>Aviation</li>
<li>Processing</li>
<li>IT&S</li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="atlass"><div id="updates" data-id-type="1"><div class="alert alert-default well" style="background-color: #f1f1f1"><i class="fa fa-spinner fa-spin"></i> Portal is Initilizing... Please Wait.</div></div></div>
<div class="tab-pane" id="avi"><div class="well" style="background-color: lightsteelblue;">Aviation Feed Will go here.</div></div>
<div class="tab-pane" id="proc"><div class="well" style="background-color: lightsteelblue;">Processing Feed Will go here.</div></div>
<div class="tab-pane" id="it"><div class="well" style="background-color: lightsteelblue;">IT&S Feed will go here.</div></div>
</div>
How do i have an event or soemthing in jquery for when the active tab is changed?
i want to call a javascript function when the active tab is changed.
i've tried this but dosent work:
<script>
$('#feedtab [data-toggle="tab"]').on('shown.bs.tab', function (e)
{
alert('test');
})
</script>

Straight out of the documentation
There are two events that get fired
show.bs.tab & shown.bs.tab as their name implies one gets fired before the new content is shown, the other one right after.
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
//e.target -> activated tab
//e.relatedTarget -> previous tab
});
