JavaScript - Determine Position Of Element From Top Of Page (not Browser)
I have a floating div that stays at the bottom of the browser window while the user scrolls down a long page. The div reads "scroll down for more". How can I determine the current position of the div in relation to the top of the page, not the top of the browser window. I need to determine this because I would like to hide the div when the user scrolls to the top of the last page. I have looked at offsetParent, offsetHeight, scrollHeight, etc.
I have the code for everything except determining the position of the div, or the distance of the div from the top of the page. Similar TutorialsI need to find the position of an element on the page relative to the browser window. Its part of a popup calendar script (and no, they don't want to change it so please don't suggest jQuery date-picker etc) The script uses these functions http://www.mattkruse.com/javascript/...on/source.html to find the position of the anchor to pop up the calendar next to it. Now the client wants to make the calendar fixed when the user scrolls so that it always stays on screen. The most graceful solution is using css position:fixed (I'm aware it doesn't work in IE6 - that's not a problem) I've been using the getAnchorWindowPosition function to get the coordinates but the numbers its giving are wrong (to different degrees depending on the browser) It was only 200px out in the Y axis in Firefox but in IE7&8 its off the screen. I've tried googling for an answer but I can't seem to find a workable solution, mostly I've been coming up with absolute position scripts or 'just use jquery' answers. I am allowing my customers to use a rich text editor (wysiwyg) on a jsp page to create snippets of HTML code that can be used to describe their items. When they want to add an image, table or custom tag (something we wrote), they are presented with a properties box created using javascript on the same page just below the editor. Upon clicking 'Insert' button on the properties box, I use javascript to create an HTML string with the tag information and insert the string into the edited page where the cursor was. The problem is that I can't seem to find a reliable way to know where the cursor was. More information: I am a C programmer who morphed to a Java programmer who knows some javascript. The JSP page looks like this: -------------------------------------------------------------------- Some text and text fields for some basic information -------------------------------------------------------------------- The javascript wysiwyg editor -------------------------------------------------------------------- The properties box (changes depending on the type of item being inserted) -------------------------------------------------------------------- Submit button, etc. for the page (so the information can be persisted) I have tried: 1. Seven days of searching the web for helpful hints. 2. Using a popup window to get the properties (doesn't work because in IE7, closing the popup also kills the session... I need to use some of the beans on the main window on the popup.) 3. Processing onMouseDown and onKeyDown events storing the element information in a global variable so I could use it later to know the point of insertion. (Has not been reliable and the arrow keys present real problems with where the cursor ends up as that is different from where it was pressed.) I am frustrated because I don't seem to be gaining on the problem. I suspect it is because I have missed something very simple. Does anyone have any ideas? Thanks in advance. Carl THIS IS NOT HOMEWORK Hi all, See this image: The image represents an "entire" web page and the bright part the area currently scrolled into by the web browser. I can get the client's screen SIZE, but I don't know how to figure how many pixels down into a page the browser happens to be. To clarify, the distance shown as a question mark would be "zero" if the browser were scrolled all the way to the top of the page and some positive number as the browser scrolls down. Is there any way for me to get this number (in Javascript). What I need it for is to position a pop-up window centered left-to-right and 1/3-2/3 top to bottom on the screen REGARDLESS of where in the page the browser is scrolled. Thanks..... -- Roger hi all, I was wondering if someone could help me about my problem I want to change the position of my div when the user scroll the page. Example: <div style="position:absolute;bottom:10px;> Scrolling text </div> I want to change the position to fixed when the user scroll the page using javascript. hope you could help. So I have created a simple calendar (http://www.akapa.org/newsite/events/calendar.htm) and I have a bunch of "More Info" buttons I made from cells. In a table cell to the right are a bunch of hidden DIV's that all appear when you rollover a "More Info" button, obviously giving more details about the calendar date/event. My problem is that I have to give an exact "top" css position to every one of these hidden div's every single time I add a new event to the calendar. I want to dynamically tell each hidden div to match the "top" css position to match the top position of each "More Info" button. How do I do that? Hello, I've been trying the find the (x,y) co-ordinates of an element. I've been using; Code: document.getElementById(element).style.top document.getElementById(element).style.left However this doesn't always work in my script. Now, I've googled how to find the position of an element. And come accross many scripts which supposedly all find the position of any object. Some are very long scripts and some are very short all using a variety of methods. Incidently none of which work, they all return (0,0). I have a question, why would someone create a script to do what one line of code can do? Am I missing something. If I understand why it may help me work out why my script isn't working. Thank you. Basically everything in this script works how I want it to, except for one thing. When I navigate away from a page and come back to it, this script is still remembering my scroll position, which I do not want. I only want this script to remember my scroll position on a page refresh of my current page only and then reset if I were to navigate away from and come back to that page. How would I go about modifying this script to work how I want it to? Thanks in advance for any help given. Code: var RecoverScroll=

Hello. My goal is to load the JS for a specific element before displaying that element. I integrated a third part script, and it works well. I set the timer he The JS is in my heading as <script type="text/javascript" src="countdownpro.js"></script> About mid-body I have: <span id="countdown1">2010-07-20 00:00:00 GMT+00:00</span> which allows for the setting of a target date to countdown to. When the page first loads it shows the above long format target time, until the js/meta tags kick in to modify it to just show the actual countdown as 00:00:00. I have attached countdownpro.js to this post. I tried shifting the function CD_Init() to the top of the script, and also appended it inline with the .html. I tried setting the big external script to "defer", but neither arrangement worked. I also tried placing the src file right at the top. I appreciate your help. Hi, So here is my problem. I have a main image that has a bunch of images (e.g., stars) on top. I place the stars in absolute positions on top of the main image. If a user resizes the brower, then the position of the main image changes, so then the stars are off position (not on top of the main image). Should I: 1) make the main image be in an absolute position? or 2) do something else such that the main image moves around if the browser is resized? but then I don't know how to re-adjust the positions of the stars on the fly. Hello. I have a table with td elements containing numbers in one row and td elements containing textareas in the second row like this: http://motionsroom.com/example.html I want to find an easy way for the user to click, draw a rectangle around or whatever around any several numbers so that they they would be put in a single td element instead of two or three (so we would have: "49 and 12" as the new value) and then the textareas below would also merge. Ideally, I would like to have a rectangle like in RTS games but then I would settle on whatever is easy. Is there any way I could do that? Thanks! Its about this: http://www.wduffy.co.uk/blog/keep-el...omment-page-1/ Everywhere is used for a whole div on some side and when its on the top of the page. But what if its in the middle..? Look here - http://phpbb.bg/viewtopic.php?f=14&p=1013#p1013 Scroll down and then up.Anyway to fix this? Hi well my problem is.. how do i hide the popup list.. i would like to if the user click outside of that div element.. the popup div will hide.. but whenever i select the body or the id containing that popup div.. the whenever i click the down arrow button.. it shows the popup div.. but then closes again.. because of the selector hide on the container div.. http://development.andrewfopalan.com/devpage/test.html here's the test page.. when i click the down arrow.. it shoes the popup.. how to do if i want that any click outside that popup element.. i will call the hide/fadeout for the popup element.. please help.. tried various things.. just a shed of light will do.. thanks Does anyone know what's wrong with this code because when the page loads, the link is not being hidden Code: window.onload = setTarget;
function setTarget()
{
var theLinks = document.getElementsByTagName('a');
for(var i = 0; i < theLinks.length; i++)
{
if(theLinks[i].getAttribute('href') == '/subjects/new')
{
theLinks[i].style.display = "none";
}
}
}
FYI http://www.hotscripts.com/forums/jav...croll-how.html Hi there, and happy new year. I am looking for a javascript code with the effect used by Google in the following example; http://www.google.co.uk/search?q=che...ient=firefox-a ... whereby the map scrolls with the page once it has been reached by the top of the browser. If anyone could point me in the right direction I would be very grateful. Many Thanks, Patrick. How do i set a page element as a variable and change it? Ive googled the internet like crazy for an answer for this, but couldnt find it. Im trying to create an animation. My question is, how do i change the width of a div onclick? Essentially, I want it to add one percent of the value of the width of the div every one second.. PHP Code: <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Loading Bar</title> <script> var x = getElementById("loadbar").style.width; function load(){ setTimeout ( "progress()", 1000 ); } function progress(){ x++; } </script> </head> <body> <div id="load" style="border:thin solid #6699FF; width:300px; height:10px"> <div id="loadbar" style="background:#6699CC; width:0%; height:100%"> </div> </div> <a href="#" onclick="load()">Click to load</a> </body> Hi I got this code for my coutdown: Code: <script language="JavaScript"> TargetDate = "12/31/2020 5:00 AM"; BackColor = "palegreen"; ForeColor = "navy"; CountActive = true; CountStepper = -1; LeadingZero = true; DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds."; FinishMessage = "It is finally here!"; </script> <script language="JavaScript" src="http://scripts.hashemian.com/js/countdown.js"></script> But i don't know how to place it where I want on my html page Normaly I use the CSS value position:absolute I want to use a windows aero theme for each div on my page. I.e. the divs are transparent and have a blur effect to them. The only way I see to achieve this is to make the div background a blurred version of the page background and use javascript to change the div background position based on the divs position on the page. I have used the demo found here as an example, but the problem with it is that the divs background position won't sync with the page background unless the user clicks on the div and moves it slightly. This isn't a problem if the divs starting position is top left, but if you want to have it start in the center of the page initially, the divs background position is top left. How could I modify this code to move the divs background to the correct position on page load? I do not want the user to be able to drag the divs. Code: $(document).ready(function () {
var dragging = true;
var startX, startY, posX, posY;
var window = $("#Panel1");
$("#header").mousedown(function (e) {
startX = e.clientX;
startY = e.clientY;
posX = window.offset().left;
posY = window.offset().top;
console.log("X: " + e.clientX + ", Y: " + e.clientY);
dragging = true;
});
$(document).mousemove(function (e) {
if (dragging) {
moveX = e.clientX - startX;
moveY = e.clientY - startY;
console.log("X: " + moveX + ", Y: " + moveY);
window.css({
left: posX + moveX,
top: posY + moveY,
"background-position": "-" + (posX + moveX) + "px -" + (posY + moveY) + "px"
});
}
}).mouseup(function () {
dragging = false;
});
});
Hi, nothing to serious, but definitely annoying. Every time i load my page, it loads to the halfway Y position down the page. I want to page to always load top every time it is refreshed or referenced to. You can see the problem here. Try and go to www.simeoncreative.com and click on any of the menu nav links. the page will load, but just halfway down the page. I tried both the Code: $(document).load().scrollTop(0); and Code: $(document).ready(function(){
$(this).scrollTop(0);
});
JS codes in the linked .js file. How can I fix this? Thanks in advance for any help. Hi. I am very new to javascript, so I might not even be wording my question right, but I am going to try and be as concise and specific as possible. I am using jquery on my website- the galleria plugin- to make a slideshow. you can see the completed show he http://www.pauljameswilliams.com/demo2a.html This slideshow will be one of three on my website. Each slide show will opperate the same exact way.I have built in tabbed navifation, and the slideshows will all be accessable under the "portfolio" tab by clicking on their corresponding links. check out the site he http://www.pauljameswilliams.com/portfolio.html As it is I have one slideshow up, although not yet connected to the corresponding link, but the images won't load. My guess is that because the div tag is hidden that the contents don't load propperly and I need the contents to load when the corresponding div tag that it is contained in becomes visible but I don't know how to do that. this is the javascript that I have written to show/hide the <div> tags where the content will live. Three slide shows will live in content_2 and show/hide when the corresponding button is pressed. Code: function tabSwitch(new_tab, new_content) {
document.getElementById('content_1').style.display = 'none';
document.getElementById('content_2').style.display = 'none';
document.getElementById('content_3').style.display = 'none';
document.getElementById('content_4').style.display = 'none';
document.getElementById(new_content).style.display = 'block';
document.getElementById('btn_1').className = '';
document.getElementById('btn_2').className = '';
document.getElementById('btn_3').className = '';
document.getElementById('btn_4').className = '';
document.getElementById(new_tab).className = 'current';
}
thank you- I am really stuck. i promise, i am actually learning javascript, I'm not just trying to get other people to do my work for me. Looking for a simple way to have a hidden element made visible when the page scrolls. The idea is to have a back arrow appear only when the page has been scrolled horizontally. trying something along these lines without success ... Code: <script type="text/javascript">
window.onscroll = function () {
if $("back").is(":hidden") {
$("back").show("slow");
}
}
</script>
The site is he www.milesjaffe.com. Thanks -- |
