Jquery Remove Div and Alert is not Working

I have a following code, i want to remove label and Input Box on click, but it is not working
no any alert is shown, nothing is seen over the console.. really disappointed
<div id="Div1" class="span5 well droppedFields ui-droppable ui-sortable">
<div class="draggableField ui-draggable droppedField" style="z-index: 10;" id="CTRL-DIV-1002">
<div style="z-index: 11;"><span id="LabelU2">LastName : </span></div>
<div style="z-index: 12;">
<input name="LastName" type="text" id="LastName"></div>
</div>
</div>
my jquery
$('.draggableField ui-draggable droppedField').on('click', function () {
$(this).parent('div.DivHTML').remove();
alert("hi");
});
Help is apperciable. thnx

Your selector doesn't point to anything. There is no draggableField that has a child ui-draggable that has a child droppedField. Do you mean a div that has all three classes?
$('.draggableField.ui-draggable.droppedField').on('click', function () {
$(this).hide();
alert("hi");
});
UPDATED CODE: Removed the OP code to remove() element and replaced with hide()

Take a look to this Fiddle
$('.draggableField').on('click', function() {
$(this).find("input").remove();
$(this).find("#LabelU2").html('');
});

you don't have DivHTML in there:
use:
$(document).ready(function(){
$('.draggableField.ui-draggable.droppedField').on('click', function () {
$(this).parent('div').remove();
alert("hi");
});
});

Can we see more details on your project? If it's working in jsfiddle but not in your project it seems like something else is missing. Are you loading jquery or your specific script into your html page properly? To get down to the problem we need more to go off of.

Bootstrap Alert Auto Close

My need is to call alert when I click on Add to Wishlist button and should disappear the alert in 2 secs. This is how I tried, but the alert is disappearing instantly as soon as it is appearing. Not sure, where the bug is.. Can anyone help me out?
JS Script
$(document).ready (function(){
$("#success-alert").hide();
$("#myWish").click(function showAlert() {
$("#success-alert").alert();
window.setTimeout(function () {
$("#success-alert").alert('close');
}, 2000);
});
});
HTML Code:
<div class="product-options">
<a id="myWish" href="" class="btn btn-mini">Add to Wishlist </a>
Purchase
</div>
Alert Box:
<div class="alert alert-success" id="success-alert">
<button type="button" class="close" data-dismiss="alert">x</button>
<strong>Success!</strong>
Product have added to your wishlist.
</div>

For a smooth slide-up:-
$("#success-alert").fadeTo(2000, 500).slideUp(500, function(){
$("#success-alert").slideUp(500);
});
$(document).ready(function() {
$("#success-alert").hide();
$("#myWish").click(function showAlert() {
$("#success-alert").fadeTo(2000, 500).slideUp(500, function() {
$("#success-alert").slideUp(500);
});
});
});
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
<div class="product-options">
<a id="myWish" href="javascript:;" class="btn btn-mini">Add to Wishlist </a>
Purchase
</div>
<div class="alert alert-success" id="success-alert">
<button type="button" class="close" data-dismiss="alert">x</button>
<strong>Success! </strong> Product have added to your wishlist.
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js" integrity="sha384-JjSmVgyd0p3pXB1rRibZUAYoIIy6OrQ6VrjIEaFf/nJGzIxFDsf4x0xIM+B07jRM" crossorigin="anonymous"></script>

Using a fadeTo() that is fading to an opacity of 500 in 2 seconds in "I Can Has Kittenz"'s code isn't readable to me. I think it's better using other options like a delay()
$(".alert").delay(4000).slideUp(200, function() {
$(this).alert('close');
});

Why all the other answers use slideUp is just beyond me. As I'm using the fade and in classes to have the alert fade away when closed (or after timeout), I don't want it to "slide up" and conflict with that.
Besides the slideUp method didn't even work. The alert itself didn't show at all. Here's what worked perfectly for me:
$(document).ready(function() {
// show the alert
setTimeout(function() {
$(".alert").alert('close');
}, 2000);
});

I found this to be a better solution
$(".alert-dismissible").fadeTo(2000, 500).slideUp(500, function(){
$(".alert-dismissible").alert('close');
});

one more solution for this
Automatically close or fade away the bootstrap alert message after 5 seconds:
This is the HTML code used to display the message:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<div class="alert alert-danger">
This is an example message...
</div>
<script type="text/javascript">
$(document).ready(function () {
window.setTimeout(function() {
$(".alert").fadeTo(1000, 0).slideUp(1000, function(){
$(this).remove();
});
}, 5000);
});
</script>
It's not limited to showing the message through JS, the message could already be displayed when the page loads.

I know this thread is old, but I just thought I would add my script for Bootstrap 5, incase anyone else needs it
<script>
setTimeout(function() {
bootstrap.Alert.getOrCreateInstance(document.querySelector(".alert")).close();
}, 3000)
</script>

Html:
<div class="alert alert-info alert-dismissible fade show js-alert" role="alert">
Javascript:
if (document.querySelector('.js-alert')) {
document.querySelectorAll('.js-alert').forEach(function($el) {
setTimeout(() => {
$el.classList.remove('show');
}, 2000);
});
}

$("#success-alert").fadeTo(2000, 500).slideUp(500, function(){
$("#success-alert").alert('close');
});
Where fadeTo parameters are fadeTo(speed, opacity)

This is a good approach to show animation in and out using jQuery
$(document).ready(function() {
// show the alert
$(".alert").first().hide().slideDown(500).delay(4000).slideUp(500, function () {
$(this).remove();
});
});

Tiggers automatically and manually when needed
$(function () {
TriggerAlertClose();
});
function TriggerAlertClose() {
window.setTimeout(function () {
$(".alert").fadeTo(1000, 0).slideUp(1000, function () {
$(this).remove();
});
}, 5000);
}

C# Controller:
var result = await _roleManager.CreateAsync(identityRole);
if (result.Succeeded == true)
TempData["roleCreateAlert"] = "Added record successfully";
Razor Page:
#if (TempData["roleCreateAlert"] != null)
{
<div class="alert alert-success">
×
<p>#TempData["roleCreateAlert"]</p>
</div>
}
Any Alert Auto Close:
<script type="text/javascript">
$(".alert").delay(5000).slideUp(200, function () {
$(this).alert('close');
});
</script>

This worked perfectly even though you clicked the button multiple times.
Here I created an onClick function to trigger the closeAlert function.
function closeAlert(){
const alert = document.getElementById('myalert')
alert.style.display = "block"
setTimeout(function(){
alert.style.display = "none"
}, 3000);
}

Load a new div into exiting div with load more button

I wanna like that some plugin just one thing must be different there is have 2 links for 2 div i wanna show there example 10 div but with only one button like "Load More" how i can do this ?
html
Click1
Click2
<div id="outer">
<div id="inner">Initial content</div>
</div>
<div style="display:none" id="hidden1">After click event showing hidden 1</div>
<div style="display:none" id="hidden2">After click event showing hidden 2</div>
Js
$(document).ready(function() {
$('.link').click(function()
{
var id = $(this).attr('href');
$('#inner').fadeOut('slow', function() {
$('#inner').html($(id).html());
$('#inner').fadeIn('slow');
})
})
})
CSS
#hideMsg{
text-align:center;
padding-top:10px;
}
http://jsfiddle.net/G5qGs/2/

You can do it something like this.
Create a load more button
Load More
Use javascript like below
var count = 1;
$('#loadmore').click(function() {
$('#inner').fadeOut('slow', function() {
$('#inner').html($("#hidden" + count).html());
$('#inner').fadeIn('slow');
count++;
})
});
Working example
http://jsfiddle.net/G5qGs/25/
P.S : You might want to display "No more content" at the end. that can be achieved using a simple if else condition

Div fading in and out

I need your help, I am working on a website where I want a div to delay for 2 seconds then fade in when another div is clicked, but when I want to click it again (to close it) I want it to fade out instantly. Any help?

If you can use Jquery, the following code will help you do it as i got what you want:
this is default css:
.invisElem{display:none}
and the jquery code:
$('body').on('click', '.boxbutton1', function(){
var counter = $(this).data('count');
if(counter == undefined){
counter = 0;
setTimeout(function() {
$('.gymtext').fadeIn(500)//fadeIn after 2 seconds(2000 ms)
}, 2000);
}
else if(counter == 0){
$('.gymtext').fadeOut(function(){
$('.gymtext').remove()
});//fadeout quickly then remove
}
})
i tried to write it down novice friendly if you needed help add comment

<script>
$(document).ready(function(){
$("button").click(function(){
$("#div").fadeToggle(240);
});
});
</script>
<button>Click to fade DIV</button>
<div id="div" style="width:100px;height:100px;background-color:blue;"></div>

Html:
<div>Show div1 and hide div2</div>
<div id="div1">Div1</div>
<div id="div2">Div2</div>
Css:
#div2 {display:none;}
Jquery:
$('#btn').click(function(e){
$('#div1').fadeOut('slow', function(){
$('#div2').fadeIn('slow');
});
});

Jquery Animation : how to make text appear when a element has changed color or styles

Umm guys i got stuck in Jquery when i was fiddling along with some animation The thing was i wanted to make a textbox appear and show the text when a button is highlighted like a gallery ummm ..... . Anyway i made halfthrough but the text is not displaying . so any help...
P.s the idea was to have a button/circle glow and a text to appear below it
like when one button/circle glows an empty space below shows the text associated with it.
<script src="jquery.js" type="text/javascript"></script>
<script type="text/javascript">
function slide()
{//slide start
$(".textHold").hide()
.delay(1000)
.queue(
function()
{//queue function start
$(".red").css(
{//css start
"background-color":"#000"
}//css end
);//css ();
$(this).dequeue();
}//queue function/\
);//queue();
$(".textHold").fadeIn(500);
$(".textr").fadeIn(500).fadeOut(5000).delay(500);
$(".textHold").fadeOut(500).delay(500);
$(".textHold")
.queue(
function ()
{
$(".red").css({"background-color":"#f00"});
$(this).dequeue();
}
)
.delay(500)
.queue(
function()
{
$(".blue").css({"background- color":"#000"});
$(this).dequeue();
}
)
.fadeIn(500);$(".text").fadeIn(500).delay(500).fadeOut(500).delay(500);
$(".textHold").fadeOut(500).delay(500);
$(".textHold").queue(
function()
{
$(".blue").css({"background-color":"#00f"});
$(this).dequeue();
}
);
}//slide() /\
setInterval(function(){slide();},500);
</script>
</head>
<body>
<div class="red">
</div>
<div class="blue">
</div>
<div class="textHold">
<span class="text">Hello blue</span>
<span class="textr">Hello Red</span>
</div>
</body>

It seems to me that the code to change the style for the button is under your control (not a third party code). In this case, you can trigger a JQuery custom event when button changes color. There would be a listener to this event which will according make the text appear.
