I have some images in my web page, and I want to display a pop up when the user hover the mouse near each image, and when the user move the mouse elsewhere, the pop up disappears
I see this functionality in a lot of site but I don't know how I can do it
I saw jquery UI but the dialog doesn't match to my goal
do you have any idea
I just tested that but no result :

thank you
wrap image with relative container and put inside absolute container (popup), show him (display:block; from display:none;) onbly then wrap container is hovered. do not forget to set z-index for popup.
You need to use jQuery mouseenter and mouseleave functions:
<p id="hover1">
Hover here!
</p>
<div id="content" style="display:none">
Content here!
</div>
$("#hover1").mouseenter(function() {
$("#content").fadeIn('fast');
});
$("#hover1").mouseleave(function() {
$("#content").fadeOut('slow');
});

Remember to include jQuery into your page.

I want to do popup like gmail chat popup window as well as I want to do pop-in like the way gmail does.
once the pop-out is done particular div should be open in new window and once the pop-in done the particular div should be placed in the position where it was been already, so far I am able to do the pop up the window in new window with the following code, but I don't have the idea how to do pop-in
Please note: once the pop-out done particular div should be open in another window and the variables in the main window also should be accessible in the pop-out window.
work out in Jsfiddle

UPDATE
I have found the option how to open the div in new window the code as follows, now I am able to pop out the window with contents in the div, now I need to know how can I access the variable value in the pop out window and how to attach back the pop out window into that original place

I would create a Named Window on the page your window expands from called eg. "HomeWindow".
Then expand window using similar to what you have, except rather using _blank give it a specific name like "ExpandedWindow"
eg.
window.open("http://YourLink.TLD","ExpandedWindow","height=200,width=400,status=yes,toolbar=no,menubar=no,location=no");
then in the pop up to Retract window use these in a click function.
window.open(document.URL,"HomeWindow");
ExpandedWindow.close();
If I understand the question correctly, you want state preserved when you popout the window. It looks like you are populating the popout HTML from the #page node, which contains an iFrame.
First of all, know that when using an iFrame, any reparenting of the iframe node will cause a reload, losing all state. It's unfortunate ;(
If I were you, I would make it so that all event handling and state management is done in the main window. You're somewhat on the right track. When you open up the popout, if the main window is holding the state you can write that state to the opened window's iframe. Likewise when you close the popout and the iframe mounts back in the main window, you can initialize it with the correct values because the main window is keeping track of the state.
The details of how to do so...I'll leave as an exercise to the reader.
I have a site made up of various html pages in jQuery mobile. On one page I have a javascript function in the content. Upon going to another page, this function still exists. How can I remove it before displaying the next page?
I am using the following, which removes the dom elements on the previous page, but the javascript functions from the previous page are still available.
$('div').live('pageshow',function(event, ui) {
$(ui.prevPage).remove();
});
$('div').live('pagehide', function(event) {
$(event.target).remove();
});
Here's the full code of two pages. Upon clicking from page 1 to page 2, the function testContent which is only on page 1 still works.

Javascript objects live until the page refreshes. This is one of the advantages of jquery mobile, as parsing JS can take a long time on mobile devices, it is considered better to do it once.
If you really need to you could set the function to null.
I think I figured this out. Basically in JavaScript a function is just another object like:
doPageShow = function(){...}
Everything set in javascript persists on subsequent ajax loaded pages, so if I set a variable in one page, it will still have that value in another ajax loaded page, including functions.
I have come across http://redactorjs.com which is a very nice wysiwig editor that has on air ability. In other words, in one single line you can turn a static div into an editable text area on the fly.
I -do not- want to pay for it (for some reasons I won't disclose) hence I am looking for an alternative.
Have you ever used a lightweight wysiwig jquery based editor that is easily usable on the fly?
I am looking for something I would use as follow:
$("#edit_btn").click(function({
$("#my_div").turnIntoEditor();
}));
$("#save_btn").click(function({
$("#my_div").post_content("http://target");
$("#my_div").turnIntoStatic();
}));
Please do not mind the post_content thingy and other function names as they are just given for reference to show the kind of usage I am looking after.
Thank you
I finally went for ckeditor. I could use it easily as follow (poc):

I am developing an application where I have the next JS code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>jQuery Hover Effect</title>
<script type='text/javascript' src="/var/www/JSPROBAK/jquery.js"></script>
<script type='text/javascript'>
$(document).ready(function(){
$(".button").hover(function() {
$(this).attr("src","/var/www/JSPROBAK/button-hover.png");
}, function() {
$(this).attr("src","/var/www/JSPROBAK/button.png");
});
});
</script>
</head>
<body>
<img src="/var/www/JSPROBAK/button.png" alt="My button" class="button" />
</body>
</html>
The directory where I have button.png, button-hover.png and jquery.js is the one specified in the code. The code is supposed to turn a gray button (button.png) into a red button (button-hover.png) when putting the mouse over the gray button. The browser initially shows the image of the gray button but doesn't turn red when putting the mouse over it so I am assuming jquery.js is not being loaded correctly, any idea?
It would appear that you are referencing the server file location not the website relative location. if you are hosting the website from the www dir then I would try this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>jQuery Hover Effect</title>
<script type='text/javascript' src="/JSPROBAK/jquery.js"></script>
<script type='text/javascript'>
$(document).ready(function(){
$(".button").hover(function() {
$(this).attr("src","/JSPROBAK/button-hover.png");
}, function() {
$(this).attr("src","/JSPROBAK/button.png");
});
});
</script>
</head>
<body>
<img src="/JSPROBAK/button.png" alt="My button" class="button" />
</body>
</html>
Looks like you are referencing the file from the server's physical path, not the virtual one. Try remove var/www/ from the URLs, and if your HTML-file already resides in /JSPROBAK/ you can specify the paths as straight out relative paths like <img src="button.png" />.
jsFiddle( http://jsfiddle.net/ZWxEg/10/ )
If this code doesn't work for you, then you're not loading jQuery correctly.

you won't be able to fade like this, if its just a solid colour you can do it with https://github.com/jquery/jquery-color
otherwise create <a> container with position relative (or another element if its not supposed to be clickable)
inside have 2 absolutely position images, one on top of the other
the underneath one is the hover and should have a lower z-index set (set z-index on both)
on the <a> hover event fadeOut the one with the highest z-index
on animation complete swap the z-indexes
I have an input which at some points happens to have the focus. If the user click in the "background" of the page, the input loses its focus. I was trying to simulate the click on the background with the following code, but this doesn't work (you will notice that the input still has the focus). Any suggestion on how to write code that simulates a click on the "background" of the page?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

<div id="main">
<form action="/">
<p>
<input type="text" id="input"/>
</p>
</form>
</div>
</body>
</html>
I would imagine using blur() would do the trick:
<script type="text/javascript">
YAHOO.util.Event.onDOMReady(function() {
document.getElementById("input").focus();
document.getElementById("input").blur();
});
</script>
Try using the blur event. If you're using jQuery there is a method you can call on the DOM object to raise this event. The blur() method should also work without jQuery.
http://docs.jquery.com/Events/blur
Your idea is right, but there is a little problem.
document.getElementById("main").focus();
<div id="main">
as shown in your code, actually the div HTMLElement doesn't have a focus method.
so you can call other elements that have a focus method or call blur() on the input element
