I have a fixed menu at the top of my screen with 4 option, each option when clicked will scroll to a section within the page. The code I am using is as follows:
$("#click1").click(function (){
$('html, body').animate({scrollTop: $("#sec1").offset().top}, 1000);
});
The scroll works as expected but when I click the options I get a flash of a white page. Has one else seen this and know any solution. Not sure if it's caused by the fixed menu element on the page.
I had this issue before. Try this:
$("#click1").click(function(e){
e.preventDefault();
$('html, body').animate({scrollTop: $("#sec1").offset().top}, 1000);
});
Here is the jQuery API: http://api.jquery.com/event.preventdefault/

I am trying to use a smooth scroll and adopted an example I found online. Here is a fiddle with my code
https://jsfiddle.net/4DcNH/144/
I have special conditions set to html and body (basically to offset the page context by 50px from the top to avoid the navbar). Therefore the smooth scroll does not work. Does anybody know a solution to this?
thanks

$(document).ready(function() {
$('a[rel="relativeanchor"]').click(function(){
$('html, body').animate({
scrollTop: $( $.attr(this, 'href') ).offset().top
}, 2000);
return false;
});
});
Is this what you're after?
$(document).ready(function () {
if(!/chrom(e|ium)/.test(navigator.userAgent.toLowerCase())){
$('html').css({'overflow-x':'auto','overflow-y':'hidden'});
}
$('a[rel="relativeanchor"]').click(function () {
var $el = $($(this).attr('href'));
$('html, body').stop().animate({
scrollTop: $el.prop('offsetTop')
}, 2000);
return false;
});
});
JSFiddle
Updates were needed in the CSS. The html overflows were removed for chrome, because otherwise, this would not work in Chrome. However, the overflows are needed for Firefox, so they are done by setting it dynamically in the JavaScript (set if not chrome).
If you want to maintain an offset, subtract it from the calculated offset. Given the above, $el.prop('offsetTop') - 50 adds 50px above.
The issue appears to be related to differences in how Chrome scrolls the <body> with height:100%. A discussion of the issue is here: Body set to overflow-y:hidden but page is still scrollable in Chrome
A workable solution is to wrap the scrolling content in <div class="content"> and disable scrolling on <body>.
Here's a JSFiddle to demonstrate the updated behavior: https://jsfiddle.net/f1zv1c5k/5/
To get the scroll to stop at the appropriate point, you need to subtract the vertical offset applied to the <html> tag (using $el.prop('offsetTop') recommended by #vol7ron) when scrolling. Your smooth scroll function would look like this:
$('a[rel="relativeanchor"]').click(function(){
var $el = $($(this).attr('href'));
$('.content').animate({
scrollTop: $el.prop('offsetTop')
}, 2000);
return false;
});
In my site, http://lol.bu.edu/ctl/home-2/, when I click on the Questrom Team Learning button, it goes to the link correctly, which is http://lol.bu.edu/ctl/home-2/#after_layer_slider_1.
However, if I manually type in the link or refresh the page in mobile (screen width less than 750px), it goes to the same height location for the link as it would normally go to for a full width (which is further down on the page for mobile).
Sometimes when I refresh the page it briefly goes to the right location before scrolling down again.
Is this a javascript problem and how would I solve it?
Your page http://lol.bu.edu/ctl/home-2/#after_layer_slider_1
remove the #after_layer_slider_1 at the end of the url. The #after_layer_slider_1 is targeting a location on your page and is why it is moving down. Jus t simply remove that part of the url and it will load at the top of the page.
and if you do not want to have it do that at all ctr+f and look for "after_layer_slider_1" in your javasrcipt, delete that part and it will stop doing the page scroll alltogether.
Just feast your eyes, on below, bro
$(document).ready(function() {
$('a[rel="relativeanchor"]').click(function(){
$('html, body').animate({
scrollTop: $( $.attr(this, 'href') ).offset().top
}, 500);
return false;
});
});
Live Demo (smooth scroll to top)
I have a html page with a form and a anchor tag at the end of the page that scroll when clicked scrolls back to the top of the page with a smooth scroll implemented using javascript.
The problem I am facing is that the scroll is jerky. There is a slight jerk before it proceeds to scroll. This doesn't happen in jsfiddle though.
I am not sure if it is because of the anchor tag or JS. Is there a way I can fix it by changing/styling anchor tag to regular text. I believe the problem is something to do with the anchor tag. I am not sure though.
Thanks
alert("Scroll triggered");
$('a[href="#register"]').click(function(){
$('html,body').animate({scrollTop: '0'}, 1000);
$('input#Name_First').focus();
});
JSFiddle: http://jsfiddle.net/BrianDillingham/co1ot6ru/7/
Your JS fiddle uses the code
$("html, body").animate({ scrollTop: "0px" }, 1000, function(){
$('input#Name_First').focus();
});
If you change it to the code provided in the question
$("html, body").animate({ scrollTop: "0px" }, 1000);
$('input#Name_First').focus();
It also jerks;
This shows that the issue is - the "focus" needs to be in the callback for the animation.
i have a long scrolling page with lots of divs, one below the other. i would like to scroll automatically when you visit (or reload) the site to scroll from top to a specific div near of the bottom. to jump there isnt a problem, but i want the "scroll" effect. ive checked out scrollTo() but i dont get it to work.
my first attempt was something like
$(document).ready(function () {
$.scrollTo('#div5'); });
but it doesnt fire anything. a little bit help needed :)
thanks
Try this:
$('html, body').animate({
scrollTop: $('#div5').offset().top
}, 500);

I try to load specific location in same page. But the problem is, the header is fixed on position top, When I click the links, the header go behind of the header. So I am not able to show some contents. Please visit this Fiddle. You can understand what I am try to say.
I dont like to add padding and margin.
You might want to change your HTML. There can be only one id per page.
In the given fiddle, you have a repeating <div id="one">
Now, to get the scroll working, you could do something like this :
$(document).ready(function(){
$("a").click(function(e) {
e.preventDefault();
var hash = $(this).attr("href");
//console.log($(hash).position().top);
$('html, body').animate({ scrollTop: $(hash).position().top - 50 }, 200);
});
});
Here $(hash).position().top gets the position of the div on the page and I subtract 50 from it (the height of the fixed div).
Here is a fiddle
