JavaScript - Fix An Element Vertically Only? Onscroll, .scrolltop ??
Hi, I'm working on a blog design. (See code below.) I'd like to fix #title vertically so that when people scroll down the blog, it stays in view in the window.
I couldn't think of a CSS way to do it. Using position:fixed doesn't work because if someone is viewing the site from a netbook, or simply from a downsized browser on their normal computer, #title is either cut off -- if it's positioned relative to the left -- or it overlaps the blog content -- if it's positioned relative to the right. I've read suggestions to use Javascript but my Javascript skills are practically non-existent. The suggestions were to use an onscroll handler, and to use scrollTop. This is what I wrote but (probably for obvious reasons) it isn't working: Code: window.onscroll = verticalFix();
function verticalFix() {
var sidebar = document.getElementById("title");
sidebar.style.top = .scrollTop(30);
}
Any advice? Also, .scrollTop is jQuery, right? So I have to link to jQuery? How do I do that, again? Thanks for your help! Here's my html and css: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

Similar TutorialsHi, I'm in need of a little help if possible please.... I would like to know if its possible to 'show' a div with the onscroll function with a javascript code? Basically, I scroll to the body position of 800 and it displays the div object. Hope ive explained correctly. Any help is hugely appreciated. Kind regards, paffley Hello. I am getting to learn JavaScript, and as for my first personal project, I would like to have a page with some text on it and when the user scrolls, a div containing a picture will move with the user when they scroll. I have found a solution, however, I do not like it. Code: <html>
<head runat="server">
<title>Test</title>
<link type="text/css" href="Main.css" rel="Stylesheet" />
</head>
<body class="mainbackground">
<div id="group">

</div>
</form>
<script type="text/javascript" >
window.onload = function () {
onscroll = function () {
var scrollevel = document.body.scrollTop;
if (scrollevel == 0) {
if (window.pageYOffset)
scrollevel = window.pageYOffset;
else
scrollevel = (document.body.parentElement) ? document.body.parentElement.scrollTop : 0;
}
scrollevel = scrollevel + 250;
document.getElementById("sizer").style.height = scrollevel + 'px';
}
}
</script>
</body>
</html>
As you can see, it works by getting the scroll position and adding 250, to a height property-element above the image div. I have tried to use document.getElementById("image").style.top = scrollevel + 'px', but it does not work. Any ideas??? Hi all, The following script is scrolling my page smoothly, as it is supposed to, in IE and FF however it is not working at all in Safari, any version. The page is: www.christiantate.net When working correctly, you click the nav buttons in the left sidebar, the page scrolls to the appropriate section. The script: Code: $(function(){
$('a[href*=#]').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'')
&& location.hostname == this.hostname) {
var $target = $(this.hash);
$target = $target.length && $target || $('[name=' + this.hash.slice(1) +']');
if ($target.length) {
var targetOffset = $target.offset().top-100;
$('html,body').animate({scrollTop: targetOffset}, 1000);
return false;
}
}
});
});
Any help would be greatly appreciated. Thanks This code not work, Code: if( document.body.scrollTop() > 200 ) {
$( '.navigation' ).addClass( 'fixed' );
} else {
$( '.navigation' ).removeClass( 'fixed' );
}
I want it to work without jQuery, because half my site die's when i use jQuery, jsut want a simple scrollTop script for when im 200px from top it locks navigation fixed top the top, it works with jQuery but not without and been trying for hours to get it to work, any help would be kindly recieve thanks. I'm trying to implement saving the document.body.scrollTop value and then restoring it but the restore does not work. The SetScrollLocation() alert line is empty. The save alert() lines displays a value so its saving the scrollTop but it seems to loose the value on the SetScrollLocation() call. I'm saving on an OnClick event and then restoring when the form reloads from a refresh. PHP Code: function SaveScrollLocation () { document.forms[0].frm_body_hidden.value = document.body.scrollTop; alert(document.forms[0].frm_body_hidden.value); } function SetScrollLocation () { alert(document.forms[0].frm_body_hidden.value); document.body.scrolltop = document.forms[0].frm_body_hidden.value; } I have created a lightbox for user display on my site. The lightbox is triggered by an onclick link. Works great but I would like to make one switch to it. I would like the lightbox to appear position:fixed; top:10px; onclick. Then if the user scrolls I would like the lightbox to appear position:absolute; top:10px; You can see an example of this here on ESPN's website http://search.espn.go.com/first-take/videos/6. If you click any video it appears position fixed onclick but then position absolute on scroll. This is what I have so far. It shows it all position fixed onclick as I desire, but stays that way on scroll. PHP Code: <a href = "javascript:void(0)" onclick = "document.getElementById('light<?php echo $count;?>').style.display='block'; document.getElementById('light<?php echo $count;?>').style.position = 'fixed'; document.getElementById('light<?php echo $count;?>').style.top = '10px'; document.getElementById('fade<?php echo $count;?>').style.display='block'"> ... [link] ... </a> PHP Code: <div id="light<?php echo $count;?>" class="log-lightbox-content-wrapper"> ... [lightbox content] ... </div> PHP Code: <style> .log-lightbox-content-wrapper {display: none; position:absolute; top: -45px; left: 50%; margin-left: -456px; width: 900px; padding: 16px;background-color: white;z-index:1002; overflow: auto; border-color:#666; border-radius:5px; border-style:solid; border-width:5px; min-height:600px; height: auto !important; height:600px;} </style> Progress: http://instride.info/admin - Click tab that says log - Then click any log post to view light box The bit of code in bold in the code below is giving me this error in IE: Error: Code: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; Trident/4.0; Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1) ; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.30729; Tablet PC 2.0; InfoPath.2; OfficeLiveConnector.1.4; .NET CLR 3.0.30729; OfficeLivePatch.1.3; MSN OptimizedIE8;ENGB) Timestamp: Tue, 16 Mar 2010 15:07:11 UTC Message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917) Line: 0 Char: 0 Code: 0 URI: http://www.mateinastate.co.uk/users/mateinastate Code: Code: if(document.getElementById('msn1').innerHTML=="")

What it's saying isn't actually true (I don't think)... this is how the section is laid out: Code: <div id="submenu1" class="anylinkcss"> <ul> <li class="contact-pm"><a href="/index.php?do=pm&act=new&to=$RateViewProfileUserName$&returnurl=$ReturnURL$">PM me</a></li> <li class="contact-email"><a href="/index.php?do=email&id=$RateViewProfileUserId$">E-mail me</a></li> <li class="contact-msn" id="msn1">$RateViewProfileUser-profile_msn$</li> <li class="contact-yahoo" id="yahoo1">$RateViewProfileUser-profile_yahoo$</li> <li class="contact-skype" id="skype1">$RateViewProfileUser-profile_skype$</li> <li class="contact-facebook" id="facebook1"><a href="$RateViewProfileUser-profile_facebook$"><span id="fbook-add"></span></a></li> </ul> </div> <script type="text/javascript" src="/html_1/js/contact-information.js"></script> Does anyone know why this might error in just IE? Hi, I'm relativly new to JS and brand new to the forum so you might need to dumb down your replys for my slightly lacking knowledge. That being said I do have a very solid grasp of html, css and am getting there with JS and its various frameworks. I'm integrating wordpress into an existing site for a friend and currently have the main blog page appear in a DIV. This is the best way to integrate in this case due to many reasons mostly of way the site is constructed. Code: <div class="scroll-pane" id="scrollbox"> WORDPRESS BLOG </div> My issue is that links within that DIV, in the blog, when clicked redirect the page. The simple answer to this would be to have them just open in a new page, which I can easily do with the below code. Code: function Init()
{
// Grab the appropriate div
theDiv = document.getElementById('scrollbox');
// Grab all of the links inside the div
links = theDiv.getElementsByTagName('a');
// Loop through those links and attach the target attribute
for (var i=0, len=links.length; i < len; i++) {
// the _blank will make the link open in new window
links[i].setAttribute('target', '_blank');
}
}
window.onload = Init;
But what I'd rather it do is have any link clicked inside the DIV to reload in that same DIV, similar to an iframe, but obviously without using an iframe, due to it's compatibility issues. Is this possible by editing the above code? If not what do I need? Thanks in advance for any help! Hi, I bought this theme in themeforest. I want to vertically align middle #silhouette and #pages the original developer gave this code var margin=$(window).height() / 100 * 15; $('#pages').css('margin-top',margin + 'px'); $('#silhouette').css('top',margin + 'px'); and asked to add in main.js in line 159 it still does'nt work perfectly and in higher or lower resolutions it does'nt get aligned in middle. Do i have to edit anything in CSS, can this JS code be optimised to work perfectly? Thanks Originally posted this in the CSS/HTML forum but I was recommended to posting it in here as it seems the solution I'm after would be JS based. Here's the build site so far, a little messy but you should be able to see what I'm after. - http://www.kierangabriel.com/lvcrft/ When you click the SHOWS link, I have a scrollto that scrolls horizontally to another (unfinished) div. What I want is for the logo box & navigation box to scroll along with the page, fixed horizontally. But when the user scrolls vertically through content, such as the stuff on the home div, I don't want the logo & nav to scroll. I found this http://stackoverflow.com/questions/1...not-vertically via googling, but I can't make much sense of it as I'm very much a JS noob. I've tried to change element id to that of mine but it didn't do anything. Any ideas? Many thanks. I was recommended to vertically align these list items using javascript. I am needing to vertically align the "identity" and "web presence" list items with each other: http://shilohcreative.gethifi.com/work#/esque Thank you in advance! Hola! I'll give you a little background before I ask you guys my question! I have a Header, a rectangle of 800x100 and directly below that I have Spry Collabsible panels stacked on top of each other with my menu items 'Home' 'About us' etc. My question is... does anyone know of a way I could vertically center everything on the page, so that when the panels are closed it is nicely in the centre and when you open one, the header moves up to allow room for the content and the whole thing stays vertically centered on the page. I'm guessing this will need some kind of fancy javascript to make possible. Thanks in advance for any advice you can give! Adam I'm trying to make my sidebar show 3 images then scroll to the next 3 automatically every 3 seconds or so. (vertically) Can anyone help me out with a reference I could look at how to do it or show a snippet of code? I've looked up various scripts for scrolling the pictures I have on the right vertically, but I can't seem to implement any of the ones I've found. I'm not trying to ask for you to code it all for me (unless you really want to), but just need some help! Thanks! Here's the site: www.beunthinkable.org hi guys, I need to implement an inline calendar showing multiple months(suppose 6 months) starting from current month in my web application. It should be possible to move to the previous months and next months. Also it should be possible to retrieve the date when a user clicks (onclick event) on a particular date. Is there any javascript source code available? could anyone please help me? thanks in advance I have the following code Code: <div class="thdnrml"> <td><a href="somelink">fonfof</a></td> </div> what i want to do is this: Code: <div class="thdnrml"> <td><a href="somelink">fonfof</a><a href="anotherlink">another_link</a></td> </div> how can i go about achieving this? Hi, (new to javascript) Code: digAudio = document.createElement("audio");
digAudio.setAttribute('src',hypeDocument.documentName()+'_Resources/'+'digging.m4a');
digAudio.id = "diggingAudio";
newAudio = document.getElementById("diggingAudio"); //returns null
the audio element is added (I can play the audio) but I can't get it by its id ? thank you Hi, Would someone here please help me with this script. I know I am a complete hack at this, but I need to get it to work. Your help is appreciated. As you can see, based on the if statement, I need to leave the Div element below hidden, or un-hide it. I know the first part works. The second part (after "else" ) is where I am having the problem. Code: <td>
<script type="text/javascript">
if ([fieldXX]==1)
{
document.write("<a href='page1.asp?itemid=1234'><img src='images/btn-choose.gif' border='0' alt='choose button'</a>");
}
else
{
var id = 'hide-buy-btn';
var item = document.getElementById(id);
if (item) {
item.className=(item.className=='hidden')?'unhidden':'hidden';
}
}
</script>
<div id="hide-buy-btn" class="hidden">

</td>
Hi all i have the following code. Code: $(document).ready(function(){
$("ul, li, a, p, img").hover(
function(){
var origBorder = $(this).css("border");
var elementID = $(this).attr("id");
$(this).css("possition", "absolute").css("z-index", "100").css("border", "1px solid red");
},
function(){
$(this).css("border", "none").css("z-index", "1");
}
);
});
it is suposed to outline the element that i am hovering over. Yet if I hover over say an <li> it will outline the li and the ul. Any ideas on how to just outline the element im hovering over? I'm trying to add an input element to all forms using appendChild. The script first searches for input elements with the name of "myinput". If it finds an input element with that name, it assigns the value "myvalue". If it can't find an input element with that name, it tries to create a new one for all forms. Code:
if (document.getElementsByName('myinput')) {
var testcode = document.getElementsByName('myinput');
for (var i=0; i < testcode.length; i++){
testcode[i].value = "myvalue";}
}
else {
var z = document.createElement("input");
z.type = "hidden";
z.name = "myinput";
z.value = "myvalue";
z.id = "mycode";
var d = document.getElementsByTagName('form');
for (var i=0; i < d.length; i++){
d.appendChild(z);}
}
What's wrong with my code? Thanks! |
