JQuery :: Keeping Floating Layers Within Window / Viewport
Aug 18, 2010
I'm working on a mysql browser / edit-in-place app which presents the user with a floating UI (think lightbox), that contains widgets appropriate for the given field they've clicked on.
Presently, rather than centering the UI element like a lightbox however, I find it best to keep it relative to their mouse, so that they don't have to traverse halfway across the screen with their mouse to interact with the interface if they've clicked something (for instance) on the bottom left.
The problem however should be apparent: if they click something towards the bottom of the screen, we need to adjust the css top/left properties so that the UI remains within the viewable area and doesn't run beyond the viewport, if possible. I've seen this done tons of times with tooltips.
I've thrown some basic awareness together using$(window).height() / width(), but if anyone could point me to a maturealgorithmfor harvesting the appropriate offset.

I have a site that I'm building at [URL] which use the jquery cycle plugin for a slideshow. I won't post the code here because it's all there with view source at the above address. It's a work in progress. The slideshow is full width (the images in it are actually 2000px wide but looks full width), and works fine apart from when the browser window is resized. This is most noticable when you start with a smaller browser window and then resize it to be bigger.
The slides stay the same width as when the page loaded - I need them to adapt to the new width. I need the slideshow to be centered at all widths, so I've put the images in as backgrounds to divs with center positioning on them. I've tried getting the window width on resize and then applying it to the slides using jQuery, but the original calculated size overrides it when the slide changes.

I am using a pre-built javascript DatePicker. It uses window.open to display
the Calendar and works fine if the user clicks on a link for a specific
date. The proper textbox in the parent window form is populated and the
DatePicker closes.
The problem is when a user clicks on the parent window, the datepicker is
hidden behind the parent window. Beleieve it or not, this creates a real
problem for many users.
Is there any way to put up an alert to the user and then set focus back to
the datepicker if the user clicks on the parent window by mistake?
In the datepicker.js there is a reference to the window created:
ggwindow = window.open(..parameters)
So I tried something like ggwindow.onblur=dont_close_me() referring to a
function that displays an Alert and then sets focus back to the datepicker
window. I know that onblur is an event and not a property or method of the
Window object, but I have also seen mentioned that the onblur event can be
applied to the Window object.
During window creation I don't see a way to set the onblur event for the
created window.

Right now, I have multiple draggable windows on my site. The problem is, that only the most recently created box is draggable and I clicking the other box doesn't work.
Where you can click and drag different boxes. The problem is I don't know how to implement this. When the two boxes are up and I click on one box, it completly ignores the other box. I realize in my code I need to update widget1 but I'm not entirely sure how I can do that. I call the method below using: document.onmousedown=selectMouse; in my javascript
If it helps, the windows are all contained in a <div> tag with the id 'closewid'
Each of the new windows that opens had the id "widget"+a number.
46 function selectMouse(e)
47 {
48 if(firefox)
49 {
50 var p=e.target;
51 if(p.attributes['id'] && p.attributes['id'].value=="titlebar")
52 {
53 //document.write(p.attributes[0].nodeValue);
54 isDrag=true;
55 x=e.clientX;
56 y=e.clientY;
57 tx=parseInt(document.getElementById('widget1').style.left);
58 ty=parseInt(document.getElementById('widget1').style.top);
59 }
60 }
61 else
62 {
63 var p=event.srcElement;
64 if(p.attributes['id'] && p.attributes['id'].value=="titlebar")
65 {
66 isDrag=true;
67 x=event.clientX;
68 y=event.clientY;
69 tx=parseInt(document.getElementById('widget1').style.left);
70 ty=parseInt(document.getElementById('widget1').style.top);
71 }
72 }

Those who have used Google notebook may notice that google notebook
displays the notes in a small floating window of the browser. I have
tried to create a similar floating window, but with no luck. Dojo has a
sample floating window, but that floating window has to exist in a
browser page, but looks like Google's floating window can exist
independently.
I also tried to debug the google notebook javascript code. It has two
compressed javascript files. One is more than 300k and the other one is
130k. It is too complicated for me to debug the code.
Anybody has some ideas how to create a similar floating window?

I'm looking for a cross-browser (IE, Netscape, Mozilla/FireFox, Opera, Safari) javascript that will keep an image (or <div>) in the lower right corner of the browser window whenever part of the web page has been scrolled vertically. I did find a script on the internet that was supposed to fit my needs, but I found it didn't work as advertised. (I included that script below.)
Requirements:
- I'm using "Frames" and the frame I want the image/div to appear in is the main content frame that sits against the right and bottom edges of the browser window. So the lower right corner of the browser window is the same as the lower right corner of my frame.
- (optional) If the frame content is small enough such that there are no scrollbars or if the page has not been scrolled vertically, then I don't want the image (or <div>) to appear.
- the placement of the image/div needs to take into account the width of the scrollbar(s).
- my focus is to display a button in this lower right corner that, when clicked, will scroll the page to the top.
I found the following script on another site that claims it would do most of this, cross browser, but I was only able to make it work with IE (and I'm using IE 6.0). When I tried it with Netscape 7.1, Firefox 1.0 (Mozilla 5.0) and Opera 7.54, the button didn't float as the page scrolled. I checked browser settings and javascript is turned on for all the browsers.
Can someone point me to a javascript that will do what I'm looking for, or help me understand why the following script isn't working cross browser? I've worked with javascript and the DOM somewhat, but am not a Master of the subject matter, especially when it comes to cross browser issues.
Thanks, and here are the instructions and script that I mentioned above (that I had founed from another site):
Place the watermark on your page where you want it to appear on non-DHTML browsers (say, the bottom). Then nest it inside a <DIV> tag with the attributes id="waterMark" and style="position:absolute". Code:

I'd have thought this would be easy but I've been looking for hours and all I can find is info on getting the viewport size, which is normally useful but not in my situation.
In this case I need the actual browser size, including the scrollbars, toolbars, status bars etc. to get an idea of browsers which aren't maximised/full screen and how big they are, and to calculate the amount of the screen taken up by toolbars etc too.

I have 50 thumbnails running vertically down the page, so that the viewer must scroll quite a bit to see them all. When a thumbnail is clicked I want to display the full size image in the middle of the viewport. Thus, the top offset of the absolute div that displays the full size picture will change depending on how far down the viewer has scrolled.
I can bind a function to the <img> tag that will set the top offset of the div where the full size images are displayed but I don't know how to get the current position of the viewport, or how to position something with respect to the viewport.
Can jQuery pull the viewport position out of the DOM and let me center something in it?

I'm using a simple toggle function to reveal divs when clicking on the associated heading. What I'm aiming to achieve:
1. When the heading is clicked, the hidden div will be revealed and the page scrolled so that the heading is at the top of the viewport.
2. If the page has insufficient height for the heading to move to the top, the page height will be increased to allow this to occur.
3. When the heading is clicked again, the div will be hidden but the heading remain in its current position at the top of the viewport. If a div is being toggled closed when not at the top, the page having been scrolled, then it should remain in its current position.
Other things to consider:
Preventing the amount of any generated empty space at the page bottom from being sufficient to fill the entire viewport.
Current state of play:
The code below will move the heading and revealed div to the top of the viewport if the page height is sufficient. When the div is hidden again, the heading drops down to its original location on the page, which is disorienting for the user.
Markup
<h2 class="trigger">Switch<h2>
<div>Content to toggle</div>
jQuery
$(document).ready(function() {
$('.trigger').next('div').hide();
$('.trigger').click(function() {
$('html,body').animate({scrollTop: $(this).offset().top}, 500);
$(this).next('div').toggle();
});
});

Essentially the idea is to make Element-B and Element-C to cover the area horizontally starting from center of Element-A and ending at the edge of viewport.So, I guess i want to get the distance value from the center of Element-A to the edge of viewport
Additional notes:
Element-A doesnt have static position or size.
Element-B and Element-C verticalposition or height is
irrelevant.
I was thinking something like this:Calculate width of Element-A and divide it by two ( Or just get half the width if theres a way. )
Get the distance from the edge of Element-A to the edge of Viewport Add up these calculated values.Of course unless theres way to get that this width straight up )I was trying to look for a way to do list item 2.

I don't know if this is a browser bug. I positioned a div at the bottom of the page just underneath the viewport, calculating it with $(document).height() and animate it to bottom:0, works great even when scrolling, cause of updating with the scroll-event. But when I reload this page or scroll down a bit the original position value was used, so it animates to the original viewport value.

I have a wordpress website with which I wish to provide content via an iframe on facebook.. Without using a wordpress plugin, I would like to know if I provide a function in jquery that basically says if viewport is equal to 520px then either load this css file or add this body class.. Also, if viewport is = to 520px then hide this element.. I think this can be done but after a lot of searching, I cannot seem to find a definative answer..

I have developed a vertical accordion menu and all is great except for the fact that some of the submenus are long and run beyond the bottom of the viewport. I need to detect the position of the UL, find out how many pixels are below the page fold, and lift the UL up by that many pixels so the UL does not go below the fold. The UL in question is positioned absolutely inside of a relatively positioned parent so I can easily use a negative top position to lift the UL but how do I get the number of pixels that the UL descends below the page fold?

I got a div, I'd like some code to be executed onClick, that'd move the div to the top of the viewport (not to the top of the page), kinda like a "vertical float".
Is there a way to do this? I've seen annoying menus/ advertisements that stick to the top of the window even if you scroll down.

I'm looking for an solution to find out the real vertical viewport -
without the height of horizontal scrollbars.
I have two frames side by side. The left one declared 'scrolling="no"'
and the right one 'scrolling="auto"'. For the left frame it is important
to know if the right frame has a horizontal scrollbar and how sick it
is. So I have tried to compare the viewport of both frames.
Using 'window.innerHeight', 'document.documentElement.clientHeight',
'document.body.clientHeight' or 'document.body.offsetWidth' I get the
height including the scrollbars.
The same problem with two frames (rows="50%,50%) i've solved with block
elements declared with a width of 100%. Comparing the offsetWidth of
both, I can see if there is a scrollbar in one frame. But with frames
side by side that doesn't work.

Example A (this works):
Code:
<html>
BLAH
<script>
alert(document.body.clientWidth + "x" + document.body.clientHeight);
</script>
</html>
[Code]...
I am working on Javascript code that gets the size of the browser viewport. My code works perfecty if the page has content. But my code does not work at all if the page has no content. Try the code examples above to see what I am talking about. How can I make it work regardless of whether or not the page has content?

now my question: I have designed a layout that has a menu in a left div layer (#left-area). When clicking on a link, it creates and opens a new div layer in the right div area (#right-area).
Each of the layers is draggable, sizable etc, but my problem is that the order they are created, is the order the z-index is set as. Explained: if i open "link 1", then "link 2", the "link 2" div will always be on top of the "link 1" div. I want the ability to change the order (z-index??), of the layer just by clicking on the layer, so that if i click on the "link 1" layer, it will bring that to the front, and the "link 2" layer will appear below it.
There must be a way to do this... i have seen examples at pupunzi.com . Is there a way to do it with jQuery. I have searched everywhere, but i cannot see the function/command.

I'd like to know if there is a way to keep a table header fixed on top of a div while I scroll the table rows. I have a div high 200px and the table itself is around 300px so when I scroll down I'd like to always see the header on top. I already use for the table tablesorter so the solution must be
compatible with that plug-in.
