View Full Version : Keeping something in place with x,y coordinates regardless of screen size

05-24-2012, 05:14 AM
Hi. I'm using HV Menu v5.5, a JavaScript vertical menu, in a website I'm redesigning. The website is 960 pixels wide, and I have it set so that it will always centered, regardless of screen size. The location of the menu is based on fixed x,y coordinates. It looks fine in the screen size I work in, but as suspected, the menu is too far to the left in larger screen sizes. Is there a way using JavaScript that I can keep the menu in the same place regardless the screen size or whether or not the browser is maximized?

wouldn't it be better to center it using css?

I need below the upper right of the header, which is 960 pixels wide and centered.

take the position x y and make it into a % of the total screen width and Hieght
using window.innerWidth, window.innerHeight
should of used % instead of Absolute good luck fixing

// where x and y are the value of the Objs placing
xpercent = (x/window.innerWidth)*100;
ypercent = (y/window.innerWidth)*100;
obj.style.left = xpercent+'%';
obj.style.top = ypercent+'%';

You will most likely have to apply % to all tags
you could Run this and get it to show the values then you can apply the %'s to your css File
Im only a Newb JavaScripter but Hope that helps.

It would be better to centre it using CSS.

Now that IE6 is dead there's no reason for using JavaScript just to put something in a fixed position on the screen since the CSS position:fixed can do it for everyone with CSS enabled (which is a much higher percentage of your visitors than have JavaScript enabled).

Centering won't work, as I've never seen a vertical menu centered in a page.

Fixing it in the upper left of a specific div using css would be great. I thought I was pretty good with css and JavaScript, but I'm not to sure how to override the JavaScript code that tells where to place the menu.

wha? never mind. I see in the documentation these options:

var MenuCentered='center'; // Menu horizontal position 'left', 'center' or 'right'
var MenuVerticalCentered='top'; // Menu vertical position 'top', 'middle','bottom' or static

no joy there?

Yeah, that doesn't do the trick. That aligns it to the overall left, center, or right of the page. StartLeft adjusts its position from there using the x coordinate. Being that the page is 960px wide, to me at least, it seem obvious to center it, and offset it -480. Unfortunately, it's not that precise, and there are some differences with screen size and browser size changes. Also, if the user maximizes the browser from whatever size it may originally be, the menu position doesn't adjust to the change.

it seems to me like the menu gets appended to the document.body at this line:


so if you wanted to append it to something else that would be the place to do it.

And then of course you will want to change accordingly all that code in there that is written to accommodate Netscape 4 users :eek:

Don't know how to do that and feeling stupid.
