jQuery - document.on hover toggle method - error

So, I've been trying to create a function in jQuery where when you hover over an element, it toggles an img, and when you exit the element, the img gets toggled again. The only issue is that this all happens after a $(document).on slector. I've tried using $(document).off().on but it's not working. Here's my code:
$(document).on('mouseover', '.addressLink', function() {
var redirectSelector = $(this).children().last();
redirectSelector.toggle('fast');
$(this).mouseleave(
function() {
redirectSelector.toggle('fast');
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='hoverDiv'>
<a class='addressLink' data-toggle='modal' data-target='#myModal'>
Click For Location <img src='download.png' class='redirect display'>
</a>
</div>
This function works the first time, but then the img toggles and toggles again and again, doing it one more time for every mouseover! The event fires once, then twice, then three times, and so on. Thank you for your answers.

I made example for you.
$(document).on('mouseover mouseleave', '.addressLink', function(e) {
var $img = $(this).find('img');
if(e.type === 'mouseover') {
$img.stop(true, true).slideDown('fast');
}else {
$img.stop(true, true).slideUp('fast');
}
});
.addressLink img {
display: block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='hoverDiv'>
<a class='addressLink' data-toggle='modal' data-target='#myModal'>Click For Location<img src='https://via.placeholder.com/150X30' class='redirect display'></a></p>
</div>

$(document).on('mouseenter mouseleave', '.addressLink', function() {
var redirectSelector = $(this).children().last();
redirectSelector.toggle('fast');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='hoverDiv'>
<a class='addressLink' data-toggle='modal' data-target='#myModal'>
Click For Location <img src='download.png' class='redirect display'>
</a>
</div>
I would suggest using a single delegate for the mouseenter and leave, since all you are doing is toggling a class. This avoids the duplicate binding issue. There is still a little flakyness with the toggle due to the element moving and the mouse may accidentally leave the target while it is redrawing, but that's an issue with styling or such that can be addresses as a secondary issue.

Try this :
$('.addressLink').hover(function(){
var redirectSelector = $(this).children().last();
redirectSelector.show('fast');
}, function(){
var redirectSelector = $(this).children().last();
redirectSelector.hide('fast');
}
);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='hoverDiv'>
<a class='addressLink' data-toggle='modal' data-target='#myModal'>
Click For Location <img src='download.png' class='redirect display'>
</a>
</div>

click a div and get the id of another div

I want to click on a element and get the id from another div which is not related to it.
I tried this:
$(".map_flag").on("click",function(){
var objective = ($(this).attr("data_modal"));
$("#" + objective).fadeIn(300, function(){
$("#" + objective).find(".modal_content").fadeIn(300);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="map_flag" data_modal="map_1">
<img src="img/image_1.png" alt="image one" >
</button>
<div id="map_1">
<p class="modal_content">place holder</p>
</div>

First of all, custom attributes need to start off with data- not with data_ (note the dash/underscore).
Then
$("#" + objective).fadeIn(300, function(){
$("#" + objective).find(".modal_content").fadeIn(300);
});
first fades in $('#map_1') and then, after that's been done, fades in $('#map_1 .modal'). Not sure if that's intended, but if the #map_1 elements has no further children, you might want to fade in only once.
For the rest, your code should work fine.

I think what you need would be something like this:
<button class="map_flag" data-modal="map_1">
<img src="img/image_1.png" alt="image one" >
</button>
<div id="map_1">
<p class="modal_content">place holder</p>
</div>
And then in JavaScript
$(".map_flag").on("click",function(){
// You should use data-* attributs as jQuery has a special function
// .data("name") that obtains the value of property data-name for example
var objective = $(this).data("modal");
$("#" + objective).fadeIn(300, function(){
$("#" + objective).find(".modal_content").fadeIn(300);
});
});

I am not very confident about my jquery skills, but dont you need to "fade out" before fade In ?

JQuery - Detecting which div box was clicked

I'm trying to detect which div box was clicked with JQuery and I'm not sure what I am doing wrong. I'm aware that I can approach this in a different method by directly calling functions if a div box is clicked, but I wish to do it this way by first determining what was clicked.
$(document).ready(function() {
$(document).click(function(event){
var id = event.target.id; //looks for the id of what was clicked
if (id != "myDivBox"){
callAFunction();
} else {
callSomeOtherFunction();
}
});
});
Thank you for any suggestions!

You could use the closest function to get the first ancestor element with tag div, see following example:
$(document).ready(function() {
$(document).click(function(event){
var parentDiv = $(event.target).closest("div");
console.log(parentDiv.prop("id"));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="div1">
<span id="span1">Test1</span>
</div>
<div id="div2">
<span id="span2">Test2</span>
</div>
I hope it helps you. Bye.

No matter what you click, you will always know the element that was clicked:
$("#myDiv").click(function(e){
alert("I was pressed by " + e.target.id);
});
Knowing that you don't want to add this to every div, and you have your click on your document, you'll need to figure out what divs can be reported as "clicked".
In order to do this you'll either need a strict hierarchy of elements in your DOM (which is anoyingly bad) or you can decorate "clickable" div's with a specific class.
Fiddle - similar to below. https://jsfiddle.net/us6968Ld/
I would use closest in Jquery to get the result you want.
$(document).ready(function() {
$(document).click(function(event){
var id = event.target.id;
var clickDiv = $(event.target).closest('div[class="clickable"]');
alert(clickDiv[0].id);
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<div class="clickable" id="clickable1">
<span id="foo"> click me - Foo - clickable 1</span>
</div>
<div id="notClickable1">
<div class="clickable" id="clickable2">
<span id="span1">
Click Me Inside Span 1 - clickable 2
</span>
</div>
<div class="clickable" id="clickable3">
<div id="notClickable2">
<div id="notClickable3">
<span id="click me">Click Me - clickable 3</span>
</div>
</div>
</div>
</div>

try this:
$('div').click(function() {
alert($(this).attr('id'));
});

get next sibling element

can someone show me how to get only the next element
like when the first button is clicked, I only want the first message show
<div>
<span class="button">Button</span>
<span class="message" style="display:none;">first button clicked</span>
<span class="button">Button</span>
<span class="message" style="display:none;">second button clicked</span>
<span class="button">Button</span>
<span class="message" style="display:none;">third button clicked</span>
</div>
here is the jquery I have so far
<script>
$(this).next().fadeIn();
setTimeout(function(){$(this).next().fadeOut();}, 3000);
</script>

Try this:
$(".button").click(function(){
$(this).next().fadeIn().delay(3000).fadeOut();
});
DEMO

for your example, next() will suffice. it grabs a reference to whatever DOM element comes next
so you would setup a click handler like so
$("button").click(function(){
var message = $(this).next();
//do whatever you want
}

You should use a click event like this instead:
$( ".button" ).click(function() {
$(this).next().fadeIn();
setTimeout(function(){$(this).next().fadeOut();}, 3000);
});

Write your script like bellow
$('.button').click(function(){
var el = $(this);
el.next().fadeIn();
setTimeout(function(){
el.next().fadeOut();
}, 3000);
})

JS slidetoggle on UL Tree

When i click on second item with slideToggle, first item close.
$(function() {
$('.toggleSitemap').find('ul').css('display','none')
$('.toggleSitemap').click(function(){
$(this).parent().find('ul').slideToggle('slow');
});
});
http://jsfiddle.net/qHZsZ/2/

I dont know how much will this help you. I also needed to implement accordian(toggle) in my MVC project once, and I used something like this:
View.aspx:
<div class='toggle' style="float: left">
<div style="float: left;clear:both;">
<br />
<span class="ulGroup" jqattr="<%:Group.Key %>" style="font-weight: bold;font-color: black;cursor: pointer"><img src="<%: Url.Content("~/Images/imageplus.gif")%>"/>
<%:Group.Key%></span>
</div>
<div class="togglebox" style="clear:both;" >
<!-- Write contents as you wish -->
<!-- as
<ul> test
<li>Test1></li>
<li>Test2></li>
<li>Test3></li>
</ul>
.
.
.
-->
</div>
</div>
And called a design.js (javascript file) as :
$(document).ready(function () {
//Hide the tooglebox when page load
$(".togglebox").hide();
//slide up and down when click over span
$(".ulGroup").click(function () {
var valueText = $(this).attr('jqAttr');
// slide toggle effect set to slow you can set it to fast too.
var x = $(this).parent().next(".togglebox").css("display");
if (x == "block") {
$(this).text('');
$(this).append($('<img src="../../Images/imageplus.gif"/>'))
$(this).append(' ' + valueText);
}
else {
$(this).text('');
$(this).append($('<img src="../../Images/imageplus.gif"/>'))
$(this).append(' ' + valueText);
}
$(this).parent().next(".togglebox").slideToggle("fast");
return true;
});
});

You're pretty close. I think the key ingredient you're missing is to prevent propagation of the click event.
Also, to make it a little less quirky, you only want the click event to fire if the target's direct parent has the toggleSitemap class.
$(function() {
$('.toggleSitemap').click(function(e){
if ($(e.target).parent().hasClass('toggleSitemap')) {
e.stopPropagation();
$(this).children('ul').slideToggle('slow');
}
});
});
