write a PHP script that detects the user's viewport width, and I am guessing stores this in a variable, then checks if it is less than or equal to 1024px using an if statement and if so attaches a certain stylesheet, lets say alternative.CSS, but in the else part of the statement; therefore, if the viewport width is greater than 1024px, it attaches or links default.css
View 8 RepliesI 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..
View 2 Replies View RelatedHow can I get visible viewport dimensions of any browser?
View 2 Replies View RelatedEssentially 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 have a perl script that i use to render a html page. In that page i call out a stylesheet. If the user has a 800x600 display the fonts are really too big.
Since screen resolution is a function of the client and I have this javascript ot detect the srecc size:
function ck_res()
{
if ( (screen.width != 1024) && (screen.height != 768) )
{
alert(" This graphic is best viewed at 1024 x 768 ! ");
// use a different stylesheet
}
}
How would I go about changing the style sheet that is being called on the page?
Is there any way to detect the width of the window in which a page is displayed? I know how to detect the screen width, but that only helps if the page is always maximized.
View 2 Replies View Relatedi would like to check for the window size with jquery and based on the different resolutions i would like to change the background image. So i was thinking to somehow use the "switch" statement for more cases, but i just don't know how this would look like. This is the basic structure i want but with more options:
if ((screen.width>=1024) && (screen.height>=768)) {
//do something
}

Is there a way to detect with javascript the scrolling bar with of the
browser?
My problem is that the the following script assing to the pos variable the browser window size but only internet explorer substracts the scrolling bar with from the result.
<script language="JavaScript" type="text/JavaScript">
<!--
var pos;
if (window.innerWidth)
{
pos =window.innerWidth;
}
else if (document.documentElement &&
document.documentElement.clientWidth)
{
pos= document.documentElement.clientWidth;
}
else if (document.body)
{
pos= document.body.clientWidth;
}
//-->
</script>
At least i want to ask if there is a script that return exactly the width of the browser's window that i have to output any text or graphic?
I know 800x600 screens occupy a shrinking part of Web surfers, but I want to accommodate them by offering an alternate style sheet where my site pages don't break when someone from this smaller group visits. Yes, there are examples of how to do this on the Web, but I have one more requirement and don't know how to code it. Not only do my pages break on 800x600, they also break if the browser widow is sized smaller on a 1024x768 screen. (I'm studying css that will dynamically respond to this but I'm not there yet.) Do I just need an appropriate if/or statement to deliver different style sheets? Is there even a JS that detects browser window changes?
View 2 Replies View Relatedi am using jquery to detect picture width and height in a page. if the size exceeds a specified value, then a maximum size will be assigned to the <img > attribute.
this jquery is run with $(window).load, because when $(document).ready the pictures may not be loaded and the script may fail
this theory is good. however, if the internet speed is slow, or the picture link is dead, user would have to wait for a long long time before the jquery executes.
is there any way to do the resizing job wisely? for example, resize each picture once each of the pictures is loaded?
How can I detect when a link has been clicked but the new page is
still in the process of loading? The document.location.href property
still displays the current location (understandably) not the one
that's about to load.
I have a page that reloads every 30 seconds in order to access live
data. If a user clicks on a link just prior to the page reloading the
reload takes precedence over the link click and this is annoying for
the users. Whe the page is about to reload I want to check to see if a
link has just been clicked (and therefore a new page is about to load)
and, if so, cancel the reload.
how to get this functionality going. I have a div name "footer". Within "footer" I have 4 links:
link1, link2, link3, link4
Is there anyway to write a function which will sense which link was clicked and then alert the id of that selected link. I have written the code but am not certain why isn't it working. here is my code.
$('#footer a').bind('click', function(){
//alert($(this).attr('id'));
var mId = $(this).attr('id');
switch(mId)

I have a navigation link ("galleries") that 'onclick' displays a sub-menu of other links (the specific galleries).
This is on the home page of my site.When a user first views the home page, the sub-menu does not display, until they click "galleries".
On other pages of my site, the "galleries" link is one of the options in my navigation. That link takes users back to the home page which is what I want it to do.But what I'm looking for to happen is if the user is directed back to the home page from within another page on my site, I'd like the link on the homepage to automatically display the sublinks under the "gallery" link.This is so that users don't have to click "galleries" twice in order to see the submenu.
For example: If a user is on the 'about me' page, in the navigation there is a 'galleries' link. If they click it, it takes them to the home page. They would then have to click on 'galleries' again on the home page in order to display the sub-menu of individual galleries.I want them to show up immediately, but only when directed back to the home page from within my site. I think I do that with an 'if' statement, but I'm not sure of the syntax.
my webstie allows users to change the color of the background, so to keep the text readable I have it changing as well.the color picker I am using has text boxes with rgb values 0-255 for each.I am trying to get one bit of text to alternate between red and blue with the conditions

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?
View 2 Replies View RelatedI 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>

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?
let me try to explain better what I'm trying to do. I'm a real newbie I don't know much javascript but I understand more or less the logic behind it... tell me if this solution should work and if you know how to do it please show me. [URL]... I need to make div#photo's width to match the total width measurement of all the images it contains. If you load the page and you don't touch the size, it will work fine... but that's not realistic. If I resize the page, which will happen often on this kind of page (I'm assuming), the whole thing goes haywire (try it, scroll to the last image and resize the page you'll see what I mean). What can I do? Is my idea the right solution? Am I not explaining this clearly enough? Let me know please, I'm desperate. I've been trying to get CSS to do this for me for 3 hours now. Nothing works.
View 6 Replies View RelatedI 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?
How can i find the DIV position (top and left) relative to viewport ?
