How do I clear data shown on mouseenter with onmouseout - javascript

When the user hovers over an image an information box comes up about that image, the information them changes inside the box as I move over another image but when I am over no images the information box stays. I can't close the information box (i.e. tooltips).
JS :
var id;
$(document).ready(function () {
$('a').mouseenter(function () {
//var id = $(this).parent().attr('myval');
id = $(this).data('myval');
$.ajax({//create an ajax request to foliobase.php
type: "GET",
//link to the foliobase.php file "?subj" here is the connector
url: "foliobase.php?subj=" + id,
dataType: "html",
success: function (response) {
$("#fillFolio").html(response);
}
});
});
$('a').onmouseleave(function () {
id = $(this).data.display = 'none';
}
});
How can I get the information box to disappear on mouse out?
I have tried multiple tests but the box doesn't even appear with them, the last one I tried is in the code above.
$('a').onmouseleave(function () {
id = $(this).data.display = 'none';
}
I am only starting out with javascript, jquery etc. in the last year.
Thank you in advance!!
Here is the php.
<div class="thumbnails">
<?php
$query = mysqli_query($connection, "select * from portfolio");
print "<ul>";
while ($row = mysqli_fetch_assoc($query)) {print "<li><img onClick=preview.src=" . $row['image'] . "name=" . $row['folio_id'] . "src={$row['image']}></td></li>";
}
print "</ul>";
?>
</div>
<!--Folio Information-->
<div id="fillFolio">Project Information</div>

I'm not sure, but try to use :
$('a').onmouseleave(function () {
$("#fillFolio").empty();
}
Hope this helps.

$("a").hover(function(){
id = $(this).data('myval');
$.ajax({//create an ajax request to foliobase.php
type: "GET",
//link to the foliobase.php file "?subj" here is the connector
url: "foliobase.php?subj=" + id,
dataType: "html",
success: function (response) {
$("#fillFolio").html(response);
}
});
}, function(){
//im not sure u want to hide or want to just clear your question not clear
$("#fillFolio").empty();
$("#fillFolio").hide();
});

Why not use jQuery hover = (mouseenter + mouseleave)
<script type="text/javascript">
var id;
$(document).ready(function () {
$('a').hover(function () {
//var id = $(this).parent().attr('myval');
id = $(this).data('myval');
$.ajax({//create an ajax request to foliobase.php
type: "GET",
//link to the foliobase.php file "?subj" here is the connector
url: "foliobase.php?subj=" + id,
dataType: "html",
success: function (response) {
$("#fillFolio").html(response);
}
});
,function () {
id = $(this).empty();
});
</script>

Update image after it's been clicked, without reloading page

I'm making this Flag/Unflag system, and it works okay. The only thing I'm struggeling with is how to update the Flag_icon, after it's been clicked? It's should be so it just changes after it's been clicked, and if it's clicked again then it changes back. Right now I have to click the flag, and then reload the page manually, and then it's changed.
$FlagStatus[$count] has the value YES/NO, from my database, and $testjobids[$count] is a unique ID from db table. I've been looking at some Ajax and Javascript to do this, but i can't seem to wrap my head around how to implement it right. I just need to be pointed into the right direction, because I'm a bit stuck.
Index.php
if ($FlagStatus[$count] == ('YES')) {
echo'<img class="Unflagging" onclick="changeImage('.$testjobids[$count].')" id="'.$testjobids[$count].'" data-id = "'.$testjobids[$count].'" src = "../Test/Images/Flag/FlagMarked.png">';
} elseif($FlagStatus[$count] == ('NO')){
echo'<img class="Flagging" onclick="changeImage()" id="'.$testjobids[$count].'" data-id2 = "'.$testjobids[$count].'" src = "../Test/Images/Flag/FlagUnmarked.png">';
}
Flagging.php / Almost same as Unflagging.php
<?php
require("../resources/MysqliHandler.class.php");
require("../resources/layoutfunctions.php");
require("GetData.php");
$ICON_DIMENSION = "16px";
// Used to connect the right server Testreportingdebug or Testreporting
$db = ServerConn();
// -------------------------------------
$MysqliHandler = new mysqliHandler($db);
$MysqliHandler->query("SET NAMES UTF8");
$receiver = $_POST["FlagID"];
$MarkYes = "UPDATE `testreportingdebug`.`testjob` SET `FlagStatus` = 'YES' WHERE id = $receiver";
$query = $MysqliHandler->query($MarkYes);
?>
Ajax
echo'
<script type="text/javascript">
$(document).on("click", ".Unflagging", function(){
var FlagID = $(this).data("id");
$.ajax({
method: "post",
url: "unflagging.php",
data: { FlagID: FlagID},
success: function(data) {
changeImage();
}
});
});
$(document).on("click", ".Flagging", function(){
var FlagID = $(this).data("id2");
$.ajax({
method: "post",
url: "flagging.php",
data: { FlagID: FlagID},
success: function(data) {
changeImage();
}
});

Form/button stop work after ajax partly reload page after form success

(If my english is bad I'm from pewdiepieland)
I have a problem that itch the hell out of me.
I have a page with a picture gallery. When logged in every picture gets a form where you can change the description or delete the picture. I also have a form where you can add a new picture to the gallery.
If I add a picture or delete/edit an existing one the part of the page where all of the pictures are shown reloads so that the new content is loaded. (since I don't want the whole page to reload and also wants to show a message about what happened, eg. "The picture was successfully uploaded/changed/deleted").
The problem is that the forms inside of the part which were reloaded stops working. I need to reload the whole page if I want to delete or edit another image. (The form for submitting a new picture still works, since it's outside of the "reloaded part of the page")
Do I have to reload the javascriptfile or anything else, or what do I need to do?
Do you guys need some parts of the code to check? It feels like I need to add something to my code to prevent this instead of changing the existing.. but hey what do I know...
Best Wishes and Merry Christmas!

I don't think you need to see my process-file. Any clues?
Your problem is probably the .click function on add and delete image so change it to $('body').on('click', 'delete_img', function() {// do something});
See Here
Your problem is that you only hook up the .click() listeners once on "document ready".
When the $(document).ready() callback is executed the gallery has already been filled and you hook up click listeners on the elements that are currently in the DOM. When you reload the gallery it is no longer the same DOM elements and no click listeners are being set up on these ones. There are a multitude of ways you correct this, for example, jQuery .load() takes a complete callback in which you can set up the event listeners. Your sample adapted with this:
$(document).ready(function() {
var setupGalleryEventListeners = function () {
$('.edit_img').click(function(e) {
e.preventDefault();
var formNr = $(this).data('number');
var dataString = $('#editimg' + formNr).serialize();
gallery('edit', dataString)
});
$('.delete_img').click(function(e) {
e.preventDefault();
var imgid = $('this').value();
gallery('delete', imgid);
});
};
$('#addimg').submit(function(e) {
e.preventDefault();
gallery('add', '');
});
setupGalleryEventListeners(); // Setup initial event listeners on page load
function gallery(a, b) {
if (a == 'add') {
var dataString = new FormData($('#addimg')[0]);
$.ajax({
type: "POST",
url: "gallery_process.php",
data: dataString,
success: function(text){
if(text == 'add_success') {
- Show success message -
$('#gallery_content').load(document.URL + ' #gallery_content', setupGalleryEventListeners); // setupGalleryEventListeners called when load is done
} else {
- Show fail message -
}
},
cache: false,
contentType: false,
processData: false
});
} else if (a == 'edit') {
var dataString = b;
$.ajax({
type: "POST",
url: "gallery_process.php",
data: dataString,
success: function(text){
if(text == 'edit_success') {
- Show success message -
$('#gallery_content').load(document.URL + ' #gallery_content', setupGalleryEventListeners); // setupGalleryEventListeners called when load is done
} else {
- Show fail message -
}
}
});
} else if (a == 'delete') {
var dataString = 'imgid=' + b;
$.ajax({
type: "POST",
url: "gallery_process.php",
data: dataString,
success: function(text){
if(text == 'delete_success') {
- Show success message -
$('#gallery_content').load(document.URL + ' #gallery_content', setupGalleryEventListeners); // setupGalleryEventListeners called when load is done
} else {
- Show fail message -
}
}

if (!theCom.val()) {
alert('You need to write a comment!');
} else {

data: 'act=add-com&id_post=' + <? php echo $id_post; ?> +'&name=' + theName.val() + '&email=' + theMail.val() + '&comment=' + theCom.val(),

Jquery ajax addClass issue

First sorry im a big beginner and just experimenting, and I made a similar wall like facebook with oembed.
And would like to add a like, and dislike button too.
I started with the like button, it works, likes, and unlikes too, and the cookie saves the class value perfectly.
My problems is the ajax call, so actually when I click on the like button it overwrites all anchors href val and adds a class to all not on what click.
here is my code
jquery
var cookieLike = "like_"
$('a.like').each(function(){
var id = $(this).attr('href'), cookieLiked = cookieLike + id;
switch($.cookies.get(cookieLiked) ) {
case "unliked":
$(this).removeClass('btn-success');
break;
case "liked":
$(this).addClass('btn-success');
break;
}
}).on('click', function(e){
e.preventDefault()
var likeId = $(this).attr('href');
$.ajax({
url: "<?php echo base_url(); ?>stream/like/" + likeId ,
type: "post",
data: likeId,
dataType: "json",
success: function(like)
{
if(like.likeStatus == "unliked") {
$('a.like').attr('href', likeId).removeClass('btn-success');
$.cookies.set(cookieLike + likeId, 'unliked');
}else if(like.likeStatus == "liked") {
$('a.like').attr('href', likeId).addClass('btn-success');
$.cookies.set(cookieLike + likeId, 'liked');
}
}
});
});
html
<div class="stream-bottom">
Komment
<div class="pull-right like-options">
<i class="icon-thumbs-up" title="tetszik"></i>
<i class="icon-thumbs-down" title="nem tetszik"></i>
</div>
</div>
could please someone point out what i am missing?
Maybe:
.on('click', function (e) {
e.preventDefault();
var button = $(this);
var likeId = button.attr('href');
$.ajax({
url: "<?php echo base_url(); ?>stream/like/" + likeId,
type: "post",
data: likeId,
dataType: "json",
success: function (like) {
if (like.likeStatus == "unliked") {
button.removeClass('btn-success');
$.cookies.set(cookieLike + likeId, 'unliked');
} else if (like.likeStatus == "liked") {
button.addClass('btn-success');
$.cookies.set(cookieLike + likeId, 'liked');
}
}
});
});
Bind the target element (the clicked link) and reference it in the success callback
In the .on('click') callback
var $link = $(this);
In the success callback use
$(this).attr('href', likeId)
instead of
$('a.like').attr('href', likeId)
When you use $("a") or $("a.like") you are referring to the entire set of anchor tags or anchor tags with 'like' as the class name. To specifically use the anchor tag on which you have clicked use $(this) variable.
That will give you the element on which the event got generated and in this case the anchor tag on which you clicked.
