Is it possible to change the position of the scroll bar relative to a new hash tag?
Currently, the page scrolls to the top of the element that is targeted using #target, which is normal behaviour. Is there a way to move it so the page scrolls to, for example, 100px further down the page than the anchor tag (adding an extra 100px before the anchor tag)?
Not sure whether cunning placement of the anchor or javascript should be used. Not sure I'm really able to change the position of the anchor so im hoping for a javascript solution.
Thanks
You could combine the answer to this question: On - window.location.hash - Change?
With some extra logic:
$(function(){
var win = $(window); //cache your jq objects!
function fixScrollTop(){
win.scrollTop(win.scrollTop() + 100);
}
if(window.location.hash !== ""){
fixScrollTop();
}
win.bind('hashchange', fixScrollTop);
});
Oh, if you have control over the #anchor in the URL, you can (probably, depending on the browser compatibility you're shooting for) set it to the ID of any element with an ID to make the browser scroll to it.

Any idea how make a layout like google plus or facebook. You can see at google plus home as example,
at the beginning, if you scroll the page in the main content, they will scroll together (friend post and sidebar), but when you scroll until the bottom of sidebar (in the right of friend post), that sidebar will stop scrolling , but the another content (friend post) will still scrolling. can explain to me how to make layout like that? sample code or demo will be very help.
Fixed positioning with CSS is a very limited approach. There are a number of ways to do this style of "fixed" areas, many of which have already been given in answers to similar questions on here (try the search above?).
One technique (which many are based on) is like so (in brief)..
Capture the browser's scrolling
Get the position from top of chosen element (x)
Check if the scrolling > x, if so apply a class to the element to fix it to a certain position.
The same will work in reverse, for example:
var target = $('#div-to-stick');
var div_position = target.offset().top;
$(window).scroll(function() {
var y_position = $(window).scrollTop();
if(y_position > div_position) {
target.addClass('fixed');
}
else {
target.removeClass('fixed');
}
}
Note: Depending on how you chose to complete the code above, the page will often "jump" as the div's position is modified. This is not always a (noticeable) problem, but you can consider getting around this by using .before with target.height() and appending a "fake" replacement div with the same height.
Hope this helps.
The new approach with css3 is reduce your effort. use single property to get it.
position:sticky;
here is a article explained it and demo.

You are looking for CSS position:fixed (for the scroll-along sidebar), you can set the location with left:[length], right:[length], top:[length], bottom:[length] and the normal width and height combos
You will need to augment it with a window resize and scroll listener that applies the position:fixed property after the window has scrolled past the top of the sidebar.
Use css property (position:fixed). This will keep the position of the div fixed even if you scroll down or scroll up.
I'm trying to write a javascript script that dynamically anchors elements to the bottom of the page when necessary. Here's a sample my code:
thebox.style.right = (window.innerWidth - topleft.Left - abs.Left - thebox.offsetWidth)+'px'
thebox.style.left = ''
thebox.style.top = (topleft.Top - abs.Top)+'px'
thebox.style.bottom = ''
This code is called when I want to anchor the element to the top and right of the page. Other code is called for other anchor positions.
The problem is, it will only anchor to the right of the page if the element was originally anchored to the right of the page to begin with. When I dynamically anchor something to the left that was originally anchored to the right, it correctly anchors to the left. And when I anchor it back to the right, it correctly anchors to the right. But if it was never anchored to the right, it never anchors to the right no matter what I do.
What am I doing wrong?
Try using this Im not sure that this is the solution but it might be worth a try.
//anchoring left
thebox.style.left= '0';
thebox.style.right= 'auto';
//anchoring right
thebox.style.left= 'auto';
thebox.style.right= '0';
Hope it works
If I understand correctly, you don't need JavaScript to position the elements. If you add your elements at body level and absolute position them, you can achieve it with just CSS. Then to change the position of any element just assign the appropriate class in JS dynamically.

I'm working on a rather full-on site using jQuery (if the solution is not using jQuery, that is also fine).
The website is built using sections that resize to the height of the window using:
$(window).resize(function() {
$("section").height($(window).height())
}).resize()
This part is working brilliantly. I have disabled scrolling by taking the overflow off the body and html elements and the user can travel through the site using relative links (with localScroll).
My issue is that once the user has travelled to a section and then resizes the window, the body is no longer in line with the top of the section.
Is there a way to make the window stick to the top of an element no matter what?
Take note of which section is current. When the window resizes, you can then set the window's scroll top to the top of that section. For example:
var currentSection = $('section:eq(0)');
var jqWindow = $(window).resize(function() {
$('section').height(jqWindow.height());
jqWindow.scrollTop(currentSection.offset().top);
});
I have done the following code in JavaScript to put focus on the particular element (branch1 is a element),
document.location.href="#branch1";
But as I am also using jQuery in my web app, so I want to do the above code in jQuery. I have tried but don't know why its not working,
$("#branch1").focus();
The above jquery (focus()) code is not working for div, whereas If i am trying the same code with textbox, then its working,
Please tell me, how can I put focus on a div elemnt using jQuery?
Thanks!
For my problem this code worked, I had to navigate to an anchor tag on page load :
$(window).scrollTop($('a#captchaAnchor').position().top);
For that matter you can use this on any element, not just an anchor tag.
Like #user293153 I only just discovered this question and it didn't seem to be answered correctly.
His answer was best. But you can also animate to the element as well.
$('html, body').animate({ scrollTop: $("#some_element").offset().top }, 500);
You can extend jQuery functionalities like this:
jQuery.fn.extend({
scrollToMe: function () {
var x = jQuery(this).offset().top - 100;
jQuery('html,body').animate({scrollTop: x}, 500);
}});
and then:
$('...').scrollToMe();
easy ;-)
Check jQuery.ScrollTo, I think that's the behavior that you want, check the demo.
Check out jquery-scrollintoview.
ScrollTo is fine, but oftentimes you just want to make sure a UI element is visible, not necessarily at the top. ScrollTo doesn't help you with this. From scrollintoview's README:
How does this plugin solve the user experience issue
This plugin scrolls a particular element into view similar to browser
built-in functionality (DOM's scrollIntoView() function), but works
differently (and arguably more user friendly):
it only scrolls to element when element is actually out of view; if element is in view (anywhere in visible document area), no scrolling
will be performed;
it scrolls using animation effects; when scrolling is performed users know exactly they're not redirected anywhere, but actually see
that they're simply moved somewhere else within the same page (as well
as in which direction they moved);
there's always the smallest amount of scrolling being applied; when element is above the visible document area it will be scrolled to the
top of visible area; when element is below the visible are it will be
scrolled to the bottom of visible area; this is the most consistent
way of scrolling - when scrolling would always be to top it sometimes
couldn't scroll an element to top when it was close to the bottom of
scrollable container (thus scrolling would be unpredictable);
when element's size exceeds the size of visible document area its top-left corner is the one that will be scrolled to;
Use
$(window).scrollTop()
It'll scroll the window to the item.
var scrollPos = $("#branch1").offset().top;
$(window).scrollTop(scrollPos);
If you're simply trying to scroll to the specified element, you can use the scrollIntoView method of the Element.
Here's an example :
$target.get(0).scrollIntoView();
I think you might be looking for an "anchor" given the example you have.
This link will jump to the anchor named jump
<a name="jump">This is where the link will jump to</a>
The focus jQuery method does something different from what you're trying to achieve.
For the focus() function to work on the element the div needs to have a tabindex attribute. This is probably not done by default on this type of element as it is not an input field. You can add a tabindex for example at -1 to prevent users who use tab to focus on it. If you use a positive tabindex users will be able to use tab to focus on the div element.
Here an example: http://jsfiddle.net/klodder/gFPQL/
However tabindex is not supported in Safari.
maybe you want to try this simple one
$(document).ready(function() {
$(".to-branch1").click(function() {
$('html, body').animate({
scrollTop: $("#branch1").offset().top
}, 1500);
});
});
I have a HTML page that scrolls up and down (not a lot, but it does scroll). How can I set the scroll position in the page after executing some JavaScript?
I'm using jQuery to inject some additional HTML at the bottom of the page and I'd like to programmatically scroll to the position of that new content after it's added.
Try using window.scroll.
Example:
// put the 100th vertical pixel at the top of the window
<button onClick="scroll(0, 100);">click to scroll down 100 pixels</button>
Another way to do this, so that you have the option:
In the HTML you are adding to the bottom of the page, you can insert a named anchor tag and then change the URL so that the page moves there (FYI: it will not refresh the page).
// add HTML like this, dynamically:
// <a name="moveHere" />
// the javascript to make the page go to that location:
window.location.hash = "moveHere";
Depending on what you are doing, this may or may not be a useful solution.
