jQuery - Click registered twice

I am making a web app that utilizes several pop ups. Inside the pop up, I have customized buttons (wrapped in <label>) that upload files. When I click on the button, it fires twice. I can solve the firing twice issue with e.preventDefault(); but obviously, it doesn't open the window for the user to upload a file.
if (document.getElementById("addItemModal").style.display !== 'none'){
$("#uploadImg").on('click', function(e) {
e.preventDefault();
console.log("I clicked upload image button.");
});
$("#uploadData").on('click',function() {
console.log("I clicked upload data button.");
});
}
So it seems that the first click is what opens the window to upload files and the second click is still a mystery. Where could this second click be coming from? I've tried .unbind as well and nothing seems to work.
EDIT: Added Code - Sorry for the wait, had to take out a lot but keep it functional and true to my problem.
var modal = document.getElementById('myModal');
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}
}
// Click Add Icon to make pop up appear
$("#myBtn").click(function() {
$("#myModal").fadeIn("fast");
$("#addModal").fadeIn("fast");
});
// Click 'x'
$("#close1").click(function() {
$("#myModal").fadeOut("fast");
});
if (document.getElementById("myModal").style.display != 'none') {
console.log("Pls don't be running twice.");
$("#upImgBtn").on('click', function(evt) {
evt.preventDefault();
console.log("I clicked upload image button.");
});
document.getElementById("upDataBtn").addEventListener('click', function() {
console.log("I clicked upload data button.");
});
}

EDIT2: I haven't included the script twice in my HTML either.

All this is happening because you are adding event to the label.
Here is your code in jsfiddle.
document.getElementById("upData").addEventListener('click', function() {
alert("I clicked upload data button.");
});
You can also make a control which element fired the event. You can put your event on label and alert only if the event was from label but this doesn't stop the click event to happen on the input button.
document.getElementById("upDataBtn").addEventListener('click', function(event) {
if( event.target.tagName === "LABEL" ) {
alert("I clicked upload data button.");
}
});
It is called once or twice cause of the bubbling because the input element is part of the label and is one union and therefor also received the event if the label is click (is is not bubbling, you can't do event.stopPropagation()).
If you make
document.getElementById("upDataBtn").addEventListener('click', function(event) {
console.log(event.target.tagName);
});
This will give you two tag names
LABEL
INPUT

Try this
$(document).on('click',"#upImgBtn", function(e) {
if (e.target !== this)
return;
console.log("I clicked upload image button.");
});
$(document).on('click','#upDataBtn', function(e) {
if (e.target !== this)
return;
console.log("I clicked upload data button.");
});

Issue with set focus on conformation box in jquery/javascript?

On click of button i need to see a custom conformation dialogue box. I am able to see it but once the dialogue box has opened then I don't want to perform any action in HTML page until user select any option in dialogue box. I mean just similar to alert box functionality, until we say "Ok" in alert box the control does not go to HTML page. I need the same , My code is as follows,
Css
<style>
#confirmBox {
z-index:9999;
display: none;
background-color: #eee;
border-radius: 5px;
border: 1px solid #aaa;
position: relative;
width: 300px;
left: 50%;
margin-left: -150px;
padding: 6px 8px 8px;
box-sizing: border-box;
text-align: center;
}
#confirmBox .button {
background-color: #ccc;
display: inline-block;
border-radius: 3px;
border: 1px solid #aaa;
padding: 2px;
text-align: center;
width: 80px;
cursor: pointer;
}
#confirmBox .button:hover {
background-color: #ddd;
}
#confirmBox .message {
text-align: left;
margin-bottom: 8px;
}
</style>
Script:
$( "#locationList" ).on( "click", "li", function( event ) {
var form = $(this).closest('form');
doConfirm("The Coordinates for Selected location are "+ coodinatesDetails, function yes() {
alert("mail");
}, function no() {
//alert("Ok"); -- Do Nothing
} , function sms()
{
alert("sms");
});
});
function doConfirm(msg, yesFn, noFn, smsFn) {
var confirmBox = $("#confirmBox");
confirmBox.find(".message").text(msg);
confirmBox.find(".yes,.no,.sms").unbind().click(function () {
confirmBox.hide();
});
confirmBox.find(".yes").click(yesFn);
confirmBox.find(".no").click(noFn);
confirmBox.find(".sms").click(smsFn);
confirmBox.show();
}
HTML:
<div id="confirmBox">
<div class="message"></div>
<span class="button yes">Mail</span>
<span class="button sms">SMS</span>
<span class="button no">Cancle</span>
</div>

You will only need an overlay to accomplish this. Try something like this: http://jsfiddle.net/7MJBR/1/
Html Changes:
<div id="confirmOverlay"></div>
<div id="confirmBox">
<div class="message"></div> <span class="button yes">Mail</span>
<span class="button sms">SMS</span>
<span class="button no">Cancle</span>
</div>
CSS Changes:
#confirmOverlay {
position:fixed;
background: rgba(0,0,0,.5);
z-index: 9998;
width:100%;
top:0px;
left:0px;
}
Javscript Change:
function doConfirm(msg, yesFn, noFn, smsFn) {
var confirmBox = $("#confirmBox");
$("#confirmOverlay").height( $(window).height() );
confirmBox.find(".message").text(msg);
confirmBox.find(".yes,.no,.sms").unbind().click(function () {
confirmBox.hide();
$("#confirmOverlay").hide();
});
confirmBox.find(".yes").click(yesFn);
confirmBox.find(".no").click(noFn);
confirmBox.find(".sms").click(smsFn);
confirmBox.show();
}
The Overlay having a Z-index of 1 below your popup, and the fact that it covers the screen will prevent people from accessing the content below. I provided filler content in my JSFIDDLE to show this.
Once the dialog and overlay are no longer needed; $('#confirmOverlay').hide() or $('#confirmOverlay').fadeOut(200) will make it go bye bye. :)
I hope this helps! Let me know if you have questions.

.stop on .mouseover or .hover

I can't figure out how to stop and resume the slide on a mouseover or hover occurrence. I basically want to stop all the scripts when .mouseover or .hover is triggered. Can anyone help me on this?

You can trigger a custom event named "stop" on carouFredSel component If you want to stop the slider.
$('#slider').trigger("stop");
And trigger a custom event named "play" with a extra parameter true to resume the slider
$("#slider").trigger("play",true);
For example:
<script>
$(function(){
$("#slider").carouFredSel({
items: 4
});
$("#slider > div.slide").hover(
function(){
$("#slider").trigger("stop");
},
function(){
$("#slider").trigger("play",true);
}
);
});
</script>
Hope this is helpful for you.

Javascript popup in html table

I have a 10 x 10 with data table that is created using html tags. If it is possible to create a onClick function to each cell? I mean, if I click on a cell, then it gives me its value in a n alert window? If yes, then how?

Plain JS - assuming <table id="table1">:
window.onload=function() {
var cells = document.getElementById('table1').getElementsByTagName('td');
for (var i=0, n=cells.length;i<n;i++) {
cells[i].onclick=function() { alert(this.innerHTML) }
}
}

A good example could be found here
HTML CODE:
<div id='page-wrap'>
Your content goes here.
<a id='show' href='#'>show overlay</a>
JavaScript & JQuery:
$(document).ready(function() {
$("#show").click(function() {
showPopup();
});
$("#popup").click(function() {
$(this).hide();
$("#mask").hide();
});
});
function showPopup() {
// show pop-up
$("#mask").fadeTo(500, 0.25);
// show the popup
$("#popup").show();
}
---------------------------------------
CSS CODE:
* { margin: 0, padding 0}
#mask{
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: #000;
display: none;
z-index: 10000;
}
#popup
{
width: 200px;
height: 200px;
margin: 10px auto;
border: 1px solid #333;
background-color: #ffffdd;
cursor: pointer;
padding: 10px;
position: relative;
z-index: 10001;
display: none;

Animate multiple elemts from middle to top with jQuery

i'm trying to move divs(actually they are AlwaysVisibleControls) from center-screen to the top of the page after a few seconds.
This is what i have:
$(document).ready(function() {
Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(PageLoaded)
});
var ScrollTopTimeOuts = [];
function PageLoaded(sender, args) {
$('.PanelNotificationBox').click(function () {
$(this).fadeOut('slow', function () {
$(this).remove();
});
});
while (ScrollTopTimeOuts.length != 0) {
clearTimeout(ScrollTopTimeOuts[ScrollTopTimeOuts.length - 1]);
ScrollTopTimeOuts.length--;
}
ScrollTopTimeOuts[ScrollTopTimeOuts.length] = setTimeout(function () {
$('.PanelNotificationBox').animate({ top: 0 }, 'slow');
}, 3000);
}
This works, but the problem is that there can be more than one notification($('.PanelNotificationBox').size()>1). Then they will overlap each other after the animation.
Q: How can i animate elements so that the first element will be on top and the next elements will keep their positions relative to the others?
Edit: After i added the notification-div(s) to a container-div and try to animate that, it won't be animated at all. This is the generated HTML/CSS(note: the outer div is an UpdatePanel):
<div id="ctl00_UpdNotifier"
<div style="top: 0px;" id="ctl00_Notifier1_PnlNotification" class="NotificationContainer">
<div style="left: 292px; top: 398px; display: none; visibility: visible; position: absolute; cursor: pointer; opacity: 1;" id="ctl00_Notifier1_InfoMsg2" class="PanelNotificationBox PanelInfo AutoHide" title="click to close notification">
<span>Test-Notification(Info)</span>
</div>
<div style="left: 292px; top: 463px; visibility: visible; position: absolute; cursor: pointer; opacity: 1;" id="ctl00_Notifier1_ErrorMsg1" class="PanelNotificationBox PanelError" title="click to close notification">
<span>Test-Notification(RMA-Error)</span>
</div>
</div>
</div>
CSS-File:
.PanelNotificationBox
{
visibility:hidden;
z-index:9999;
width: 50%;
font-weight: bold;
font-size:small;
border: 1px solid;
margin: 10px auto;
padding: 20px 20px 20px 60px;
background-repeat: no-repeat;
background-position: 8px center;
box-shadow: 2px 2px 3px #3A4F63;
border-radius: 4px;
}
.PanelInfo {
color:Black;
background-color: InfoBackground;
background-image: url('../images/info-icon.png');
}
.PanelError {
color:White;
background-color: red;
background-image: url('../images/error-icon.png');
}

I suggest to place all your messages in a div, and set this div on abosule position on the top of the page and animate this div that holds all the messages. I think that you can even just place all your element in this div, and they arrange by him self the one afther the other.
<style type="text/css">
.Containerv {
position:absolute;
left:10px;
top:10px;
width:230px;
}
</style>
<div id="ContainerID" class="Container">
<div>First element</div>
<div>Second element</div>
<div>.... next elements</div>
</div>
and your javascript
$(document).ready(function() {
Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(PageLoaded)
});
var ScrollTopTimeOuts = [];
function PageLoaded(sender, args)
{
// keep this to indivitual close messages
$('.PanelNotificationBox').click(function () {
$(this).fadeOut('slow', function () {
$(this).remove();
});
});
clearTimeout(ScrollTopTimeOuts);
ScrollTopTimeOuts = setTimeout(function () {
$('#ContainerID').animate({ top: 0 }, 'slow');
}, 3000);
}

The approaches from #Yoshi and #Aristos had the disadvatage of breaking the AlwaysVisibleControls js-functionality. Thank you anyway :)
I ended with this solution what is working fine(leaving out the timer part):
var first=$('.PanelNotificationBox:first');
$('.PanelNotificationBox').each(function (index) {
$(this).animate({ top: '-=' + first.offset().top }, 'slow');
});
