Not support hover function?

Mouse function cannot be support
$("div.container1:has('#image')").hover(function() {
console.log("Success hover");
});
and this is my div class
<div class="container1">
<img src="img/1920/blue.jpg" id="imageId"/>
</div>
functionality in div class for click action
$(document).ready(function() {
$(".container1").click(function(e) {
e.preventDefault();
var x = e.pageX - this.offsetLeft;
var y = e.pageY - this.offsetTop;
var img = $('<button>');
img.css('top', y);
img.css('left', x);
img.css('position', 'absolute');
img.attr('type', 'button');
img.attr('id', 'image');
img.css('z-index', 1);
img.attr('class', 'btn btn-info btn-lg');
$(this).attr('data-toggle','modal');
$(this).attr('data-target','#myModal');
img.attr('data-toggle','modal');
img.attr('data-target','#myModal');
console.log("Mouse action Start");
img.appendTo('.container1');
/*$(this).removeClass('.container1');*/
console.log("Mouse action End");
$(this).removeClass('<button>');
});
});

Another way of selecting works , jsbin
$("div.container1 #imageId").hover(function() {
console.log("Success hover");
});

It is because .hover takes two parameters. A callback for when the mouseenters, and a callback for when it leaves.
Also, are you adding the DOM element and THEN adding the click handler? If so, you definitely need to use .on().
.on() is used for elements that are added dynamically to the DOM.
you probably need to do .on('mouseenter', [callback]) AND .on('mouseleave', [callback]) rather than .hover(). just fyi.

Map Informations with fadeIn and fadeOut

I have a map with some pinpoints that, if you click on them show some information. The plan was, that I can click a Icon and it shows a div, if I now click the same icon the div will disapear.
As long as i got show() it works but if I put in fadeIn() it reapears on the second click.
Here my script so far
<script type="text/javascript">
jQuery(document).ready(function() {
$(".icon-location").on('click', function(event){
$('[id^="ort-box-"]').fadeOut('slow');
});
var mouseX;
var mouseY;
$(document).ready(function(e) {
mouseX = e.pageX;
mouseY = e.pageY;
});
$(".icon-location").on('click', function(event){
var currentId = $(this).attr('id');
$("#ort-box-"+currentId).show().css({position:"absolute", top:event.pageY, left: event.pageX, "z-index":"998"});
});
});
</script>
EDIT:
Thanks to Max I got something startet but there is some logic mistake I must have made.
$(".icon-location").on('click', function(event){
$('[id^="ort-box-"]').fadeOut('slow');
if(!$(this).hasClass('ortActive')){
var currentId = $(this).attr('id');
$("#ort-box-"+currentId).fadeIn('slow').css({position:"absolute", top:event.pageY, left: event.pageX, "z-index":"998"});
$(this).addClass('ortActive');
}else {
$(this).removeClass('ortActive');
}
});

You're attaching 2 eventhandlers on the same DOM element.
So if you click on it, both handlers will fire the event and both functions will be called.
Maybe use something like
$(this).addClass('active');
if you trigger the event for the first time, check when you press again with
if($(this).hasClass('active')){ ...
$(this).removeClass('active');
}
This way you can be sure, that you can trigger only the wanted parts of the event handlers.

jQuery - How to destroy an event which is attached to an element?

I have some line of codes which will move an element to mouse position after it is mousedown-ed.
I want to remove the event attached to it, so it won't following the mouse position anymore after it is mouseup-ed!
The Problem
The element still follows the mouse after mouseup!
I want it to follow the mouse on mousedown and stop following the mouse after mouseup! How do I remove the mousemove listener from the element?
Here is the JS
jQuery(document).ready(function ($) {
$(".crossY").on("mousedown", function (e) {
var j = $(this);
$(document).on("mousemove", function (e) {
j.css({
"top": e.pageY,
"left": e.pageX
});
});
})
$(".crossY").on("mouseup", function (e) {
var j = $(this);
$(document).on("mousemove", function (e) {
j.css({
"top": j.css("top"),
"left": j.css("left")
});
});
});
});
and the FIDDLE DEMO

In order to remove a mouse listener, you need to use the jQuery .off method. In order to get this to work easily, you should namespace the mousemove event. This will allow you to easily detach the necessary mousemove listener.
Inside the mousedown we want to attach the listener
$(document).on('mousemove.following', function (e) { /* my event handler */ })
Inside the mouseup we want to detach the listener
$(document).off('mousemove.following')
The following namespace makes sure that no other event listeners are detached.
Here is an example of this working (your jsfiddle except updated).
Another thing you might want to do is make the moving part centered underneath the mouse.
$(".crossY").on("mousedown", function (e) {
var j = $(this);
var height = j.height(), width = j.width();
$(document).on("mousemove", function (e) {
j.css({
"top": e.pageY - height/2,
"left": e.pageX - width/2,
});
});
})
Subtracting half of the element height and width keeps the element centered underneath the mouse, which will also ensure that the mouseup even is fired.

try using bind() and unbind() like this: DEMO
jQuery(document).ready(function ($) {
$(".crossY").on("mousedown", function (e) {
var j = $(this);
$(document).bind("mousemove", function (e) {
j.css({
"top": e.pageY-10,
"left": e.pageX-10
});
});
})
$(".crossY").on("mouseup", function (e) {
var j = $(this);
$(document).unbind("mousemove");
});
});

Try
jQuery(document).ready(function ($) {
$(".crossY").on("mousedown", function (e) {
var j = $(this);
$(document).on("mousemove", function (e) {
j.css({
"top": e.pageY,
"left": e.pageX
});
});
})
$(".crossY").on("mouseup", function (e) {
var j = $(this);
$(document).off("mousemove");
});
});

.on event keeps getting fired over and over again

I'm trying to setup an event where it fires after my element is opened. So I have a tooltip and I have a click event which shows the tooltip. Then when that happens I setup a document click event that gets fired so if the user clicks anywhere on the stage it removes all tooltips. But what's happening is it gets called before the tooltip even gets a chance to show. So it's firing the document event over and over again.
$('.container img').popover({placement:'top', trigger:'manual', animation:true})
.click(function(evt){
evt.preventDefault();
el = $(this);
if(el.hasClass('active')){
el.popover('hide');
}else{
clearDocumentEvent();
el.popover('show');
$(document).on('click.tooltip touchstart.tooltip', ':not(.container img)', function(){
hideAllTooltips();
});
}
el.toggleClass('active');
})
var hideAllTooltips = function(){
$('.container img').popover('hide');
$('.container img').removeClass('active');
}
var clearDocumentEvent = function(){
$(document).off('click.tooltip touchstart.tooltip');
};

The problem stems from event bubbling. You can verify this by doing the following test:
$(document).on('click.tooltip touchstart.tooltip', ':not(.container img)', function(){
//hideAllTooltips();
console.log($(this)); // will return .container, body, html
});
Try using event.stopPropogation():
$(document).on('click.tooltip touchstart.tooltip', ':not(.container img)', function(e){
e.stopPropagation();
hideAllTooltips();
});
DEMO:
http://jsfiddle.net/dirtyd77/uPHk6/8/
Side note:
I recommend removing .tooltip from the on function like
$(document).on('click touchstart', ':not(.container img)', function(){
e.stopPropagation();
hideAllTooltips();
});

Get mouse location during mouse down?

How can I continuously get the position of the mouse whilst its button is being held down?
I know I can do:
<element onclick="functionName(event)"></element>
<script>
function functionName(e){
e.pageX
e.pageY
//do stuff
}
</script>
and I know you can use the onmousedown event, but how would I continuously get the position while the button is still held down?
Oddly I couldn't find this anywhere I looked.

Anyway, I'd suggest using mousemove event with check if which event property equals 1 (i.e. left mouse button pressed):
$("element").on("mousemove", function(e) {
if (e.which == 1) {
console.log(e.pageX + " / " + e.pageY);
}
});​
DEMO: http://jsfiddle.net/HBZBQ/

Here is a JSFiddle for you. You need to store the state of the mouse button in a variable.
jQuery:
$(document).ready(function() {
$(document).mousedown(function() {
$(this).data('mousedown', true);
});
$(document).mouseup(function() {
$(this).data('mousedown', false);
});
$(document).mousemove(function(e) {
if($(this).data('mousedown')) {
$('body').text('X: ' + e.pageX + ', Y: ' + e.pageY);
}
});
});​
Here, I'm storing the mouse button's up or down state in document using $(document).data(). I could have used a global variable, but storing it this way makes the code a little cleaner.
In your $.mousemove() function, only do what you want if the mouse is down. In the code above, I'm simply printing the mouse's position.
