Turn Inline OnClick to Click Jquery

I have the following inline styles for a dropdown menu list. I do not know how to make it in to 'click' using jQuery.
<button class="btn btn-primary mw" data-toggle="dropdown"><span class="caret">Subject</span></button>
<div class="dropdown-menu">
<a class="dropdown-item Business" onclick="selectBusiness()"> Business</a>
<a class="dropdown-item ICT" onclick="selectICT()"> ICT</a>
<a class="dropdown-item Arts" onclick="selectArts()"> Arts</a>
</div>
More information:
I tried to do this following code for a button and it's working fine. But as I said I do not know how to make it work for a dropdown menu.
var btn = document.querySelector("button.selectAll");
btn.addEventListener("click", selectAll);
....
Your input would be greatly appreciated!

If you want to use jQuery, you can add listener to the classes of each <a> inside your dropdown.
$(".Business").on('click', function() {
//selectBusiness() or your code here
});
$(".Arts").on('click', function() {
//selectarts() or your code here
});
$(".ICT").on('click', function() {
//selectICT() or your code here
});
Another solution would be to add a single listener for all your dropdown-items and then checking the content of the selected one.
$(".dropdown-item").on('click', function() {
switch ($(this).text()) {
case "Business":
selectBusiness();
break;
}
});

jquery script doesn't work for me

$('a.locked').click(function(e) {
e.preventDefault();
});
$(document).ready(function(){
$("button.button2").click(function(){
$("a").removeClass("locked");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="example.com"target="_blank" id="action2">
<button class="button2">
<span class="icon">CLICK HERE</span>
</button>
<br>
<br>
</a>
<a href="example.com"class="locked">
<button class="locked-button">
<i class="fa fa-lock" aria-hidden="true"></i>
<span class="icon">CONTINUE</span>
</button>
</a>
I want that the last a element is locked, and if you click on the 2nd button, the class locked will be removed from the last a element and I will be able to click on the link.
It deletes the class but I still can't click the link. How to fix that?
Also, is there are smarter way to do that...

This event binding isn't removed from the <a> when its class="locked" is removed:
$('a.locked').click(function(e) {
e.preventDefault();
});
At least with direct bindings like this, jQuery only uses the selector initially to attach the event handler to all matching elements. It won't recheck the selector when the event is later triggered. Currently, you'll have to do that check yourself:
$('a').click(function (e) {
if ($(this).hasClass('locked')) {
e.preventDefault();
}
});
Though, if you have an overall parent element, you can use a delegated binding and jQuery will then recheck the (2nd) selector for you when the event is triggered.
<div id="parent">
<a href="example.com" target="_blank" id="action2">
<!-- ... -->
</a>
<a href="example.com" class="locked">
<!-- ... -->
</a>
</div>
$('#parent').on('click', 'a.locked', function (e) {
e.preventDefault();
});

So, just removing a css class will not work in your case.
You should remove the event handler to allow the button to be clicked, something like this should work:
$("a.locked").on("click.locked", function(e) {
e.preventDefault();
});
$(document).ready(function(){
$("button.button2").click(function(){
$("a.locked").off("click.locked");
$("a").removeClass("locked");
});
});
Working jsfiddle.

Like this?
Check out this SO question to read more about the toggle function I used.
$(document).on("click", "#ToggleLock", function(e) {
$('#Continue').prop('disabled', function(i, v) {
return !v;
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button type="button" id='ToggleLock'>Unlock/Lock</button>
<button onclick="location.href='http://www.example.com'" type="button" id='Continue' disabled>Continue</button>
Let me know if I have greatly misunderstood the question.

Remove the class is not enough, since you added a click event to all $('a.locked') you need use .off() to remove the click event after removing the class. Also try to target the specific element, you could add id="btn_continue" to 2nd button. ($("a") will target all <a> which is not what you want to do)
Note:
$('a.locked').click(function(e) {
e.preventDefault();
});
$(document).ready(function(){
$("button.button2").click(function(){
$("#btn_continue").off().removeClass("locked");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="example.com" target="_blank" id="action2">
<button class="button2">
<span class="icon">CLICK HERE</span>
</button>
<br>
<br>
</a>
<a href="example.com" id="btn_continue" class="locked">
<button class="locked-button">
<i class="fa fa-lock" aria-hidden="true"></i>
<span class="icon">CONTINUE</span>
</button>
</a>

Bootstrap Tooltip remains stuck

I am dynamically creating a div using jquery which contains add & close button. I am using Bootstrap tooltip for the add & close buttons. The problem that I am facing is Tooltip of the first add button doesn't gets hidden even when the mouse is hovering other add button. The tooltip of first add button remains as it is.(Refer screenshot) Any idea as to how to make it hidden.
I am using jquery clone method to create the dynamic divs.
$(document).on('click', ".addFilesBtn", function(e) {
e.preventDefault();
$(".appendClass:first").clone().appendTo".addFiles");
$('.closeFilesBtn').show();
$('.closeFilesBtn:first').hide();
});
Also for hiding the tooltips, I am using the below code but still the first tooltip is not getting hidden.
$(document).on('mouseleave','[data-toggle="tooltip"]', function(){
$(this).tooltip('hide');
});
updated HTML Code
<div class="row addFiles">
<div class="appendClass" style="margin-bottom: 1.5%;">
<label style="white-space: nowrap;" class="responsive-enter-details col-sm-3 control-label">Select Files</label>
<div class="col-sm-8 col-md-9">
<div class="fileinput fileinput-new" data-provides="fileinput">
<div class="form-control" data-trigger="fileinput">
<i class="glyphicon glyphicon-file fileinput-exists"></i> <span class="fileinput-filename">Click to select file</span> <i class="fa fa-upload pull-right"></i>
</div>
<input id="inputfile" type="file" style="display: none;">
</div>
</div>
<button class="btn btn-box-tool addFilesBtn" data-toggle="tooltip" title="Click to add more files">
<i class="fa fa-plus"></i>
</button>
<button class="btn btn-box-tool closeFilesBtn" data-toggle="tooltip" title="Click to remove this block">
<i class="fa fa-times"></i>
</button>
</div>
</div>
Link to JS Fiddle:
https://jsfiddle.net/gLkrsbxc/4/
As you can see in JS Fiddle, the tooltip isn't getting closed.

Please check the last update for solution
As mentioned in the docs at http://getbootstrap.com/javascript/#tooltips, you need to initialize all the tooltips e.g.
$(function () {
$('[data-toggle="tooltip"]').tooltip()
})
So, here you just need to initialize the tooltips after adding them to the DOM.
Just add $('[data-toggle="tooltip"]').tooltip() in your click function after cloning.
$(document).on('click', ".addFilesBtn", function(e) {
e.preventDefault();
$(".appendClass:first").clone().appendTo".addFiles");
//initialize tooltips(add this line)
$('[data-toggle="tooltip"]').tooltip();
$('.closeFilesBtn').show();
$('.closeFilesBtn:first').hide();
});
And I think if initialized properly, you won't need the hide function.
Update:
I think calling the initializing function doesn't work properly because it is a problem when dom manipulation operations are performed. Add slight delay after the append function and before the initializing function with setTimeout like this:
$(document).on('click', ".addFilesBtn", function(e) {
e.preventDefault();
$(".appendClass:first").clone().appendTo".addFiles");
//initialize tooltips(give some time for dom changes)
setTimeout(function() {
$('[data-toggle="tooltip"]').tooltip();
}, 50);
$('.closeFilesBtn').show();
$('.closeFilesBtn:first').hide();
});
Update 2
Just hide the tooltip of the button you just clicked before cloning:
$(document).on('click', ".addFilesBtn", function(e) {
e.preventDefault();
//hide the tooltip
$(this).tooltip('hide');
$(".appendClass:first").clone().appendTo(".addFiles");
$('.closeFilesBtn').show();
$('.closeFilesBtn:first').hide();
});

How to remove data-target and data-toggle from child elements or disable elements from triggering the event?

HTML:
<div id="card_{{_id}}" class="card-panel" data-toggle="modal" data-target="#{{_id}}">
<span class="white-text">{{text}}</span>
<div class="card-action">
{{#each tags}}
<div class="chip">
<tag class="tag">{{this}}</tag>
<i id="removeTag" class="material-icons fa fa-ban"></i>
</div>
{{/each}}
<div class="chip" id="likeButton">
<i class="fa fa-thumbs-o-up"></i> {{likes}} Likes
</div>
</div>
</div>
above is sample html code from my meteor project. i want the div#card element to activate the modal by clicking on it. But i do not want the div.chip elements to toggle the modal when clicked. Is there a way i can disable child element from the data-toggle of the modal?

If you can use javascript, you can do stopPropagation for stopping click event on div.chip from bubbling to div#card.
$('.chip').on('click', function (ev) {
ev.stopPropagation();
});
For elements in a meteor template, you do something like this (replace yourTemplate with your template name),
Template.yourTemplate.events({
'click .div', function (ev, template) {
ev.stopPropagation();
}
});

Audio wont play after loading contents with AJAX

First of all im new to jquery i have tried googling my problem , spent hours to fix this and i couldn't find any , so here i am .
In the below code i have fetched some information ( Songs details ) from database and loaded them to div via ajax .. Up to this point everything works just fine .
script using to load content via AJAX
$(document).ready(function() {
$("#results" ).load( "ajax/profile_ajax.php"); //load initial records
//executes code below when user click on pagination links
$("#results").on( "click", ".pagination a", function (e){
e.preventDefault();
$(".loading-div").show(); //show loading element
var page = $(this).attr("data-page"); //get page number from link
$("#results").load("ajax/profile_ajax.php",{"page":page}, function(){ //get content from PHP page
$(".loading-div").hide(); //once done, hide loading element
});
});
});
<div class="loading-div"><img src="../pagination/ajax-loader.gif" ></div>
<div id="results"></div><!-- content will be loaded here -->
Script im using to play audio
$(function () {
var curAudio;
$(".playback").click(function (e) {
e.preventDefault();
var song = $(this).next('audio')[0];
if (curAudio && song != curAudio && !curAudio.paused) {
curAudio.pause();
$(curAudio).prev().html('<i class="fa fa-play"></i> Play');
}
if (song.paused) {
song.play();
curAudio = song;
$(this).html('<i class="fa fa-pause"></i> Stop');
} else {
song.pause();
curAudio = undefined;
$(this).html('<i class="fa fa-play"></i> Play');
}
curPlaying = $(this).parent()[0].id;
});
});
I have above code to played the fetched music . Now the problem is None of the Buttons are functional even though my code worked fine before i use AJAX .
My Fecthed HTML is like this
<div id="4">
Track Name :- <b>Heros</b>
<br />By :- <a target="_blank" href="../members/profile.php?id=1">USER NAME</a>
<br />
<button class="playback btn btn-primary btn-sm hdnbtn"><i class="fa fa-play"></i> Play</button>
<audio src="../members/memberfiles/1/Heros.mp3">
Your browser does not support HTML5 audio.
</audio>
<a class="btn btn-sm btn-success hdnbtn" href="../members/downloader.php?fld=1&name=Heros.mp3" name="dwn"><i class="fa fa-download"></i> Download MP3</a>
<button class="sharer btn btn-sm btn-danger hdnbtn" type="button"><span class="fa fa-share-alt"></span> Share</button>
<a target="_blank" href="#" class="hide btn btn-sm btn-social btn-facebook socialhdn"><i class="fa fa-facebook"></i> Share on Facebook</a>
<a target="_blank" href="#" class="hide btn btn-sm btn-social btn-twitter socialhdn"><i class="fa fa-twitter"></i> Tweet this </a>
<a target="_blank" href="#" class="hide btn btn-sm btn-social btn-google-plus socialhdn"><i class="fa fa-google-plus"></i> Share on goole</a>
<br />
<i class="fa fa-minus"> Show Less</i>
<input type="hidden" value="Heros.mp3" name="file_name">
<input type="hidden" value="bWVtYmVyZmlsZXMvMS9IZXJvcy5tcDM=" name="link">
What i really need is to play the fetched content using the 2nd script (audio) i posted . i have no idea how to fix this . Tried hours of googling and various suggested methods. None of them worked for me . Please Point out what went wrong . i really appreciate it !

use below code to play audio . you also check Event delegation to attach event to dynamically created element. Event delegation allows us to attach a single event listener, to a parent element, that will fire for all descendants matching a selector, whether those descendants exist now or are added in the future.
$(function () {
var curAudio;
$(document).on('click',".playback",function (e) {
e.preventDefault();
var song = $(this).next('audio')[0];
if (curAudio && song != curAudio && !curAudio.paused) {
curAudio.pause();
$(curAudio).prev().html('<i class="fa fa-play"></i> Play');
}
if (song.paused) {
song.play();
curAudio = song;
$(this).html('<i class="fa fa-pause"></i> Stop');
} else {
song.pause();
curAudio = undefined;
$(this).html('<i class="fa fa-play"></i> Play');
}
curPlaying = $(this).parent()[0].id;
});
});
