I was wondering if the following is possible. Currently I have some code which opens a DIV at the bottom of the page using jquery. It is something as simple as this:
$("#country_slide").slideToggle();
Then I have some example code which scrolls to the bottom of the page (just an example):
$('html, body').animate({scrollTop:$(document).height()}, 'slow');
The trouble is this div that opens up will be off the bottom of the page when it expands, so I want it to not only open but also have the page scroll down to show the now opened div as it is opening.
I can only work out how to fully expand the div, then scroll to the availible area. I want both processes to run at the same time, not one after the other.
Is this possible with jquery, and if it is, can someone please explain how.
Check out this fiddle: JsFiddle
I am calling the events, to display (show, fadeIn, slideDown, etc..) and scroll to element, when the $(document) is ready.
I placed timers in milliseconds for the display function at 3 seconds, and the scroll to at 4 seconds. You can adjust these times as necessary to display your hidden element as you see fit.
CSS
#container{height:850px;background-color:red;width:300px;text-align:center; }
#bottomDiv{display:none;position:relative;top:400px;width:260px;height:200px; background-color:dodgerblue;margin:20px auto;border: 1px solid #000000;text-align:center;}
HTML
<div id="container" style="height:1500px;background-color:red;width:300px;">
<p>I'm opening a div and scrolling below</p>
<div id="bottomDiv" class="tempCss">Bottom Div</div>
</div>
SCRIPT
$(document).ready(function(){
$("#bottomDiv").slideDown(3000);
$('html, body').animate({ scrollTop: $("#bottomDiv").offset().top }, 4000,function(){
});
});

I have a series of divs, that serve as a demo page. Initially I have only the first div showing, with the other 2 hidden using jQuery hide() on page load.
There is a button on each div which triggers a jQuery event of hiding the current div and showing the next div in the sequence.
I would like on the very last div (div 3), once displayed to also show the previous 2 divs, but to have div 3 still display. Meaning, the user can scroll up to see the other two divs, but without scrolling they will still be viewing div 3.
$(document).ready(function () {
$(".page-2").hide();
$(".page-3").hide();
$(".overlay").show();
$(".overlay-button").click(function () {
$(".overlay").hide();
$(".page-1").fadeOut(1000);
$(".page-2").show("slow");
});
$(".arrow-down").click(function () {
$(".page-2").fadeOut(1000);
$(".page-3").show();
$(".page-2").show();
$(".page-1").show();
});
});
This code brings the view back up to the first div (".page-1").
The problem is that when you have all of them open the height of the page changes and the scrollbar gets left behind, to fix this you can force the scrollbar to scroll to the bottom of the page with the following snippet:
$('html, body').scrollTop($(document).height());
I am using .load() to refresh the contents of a div every 5 seconds.
When the div updates, the whole page will scroll back up to the top. Is there any way to prevent this from happening?
<body>
<app-header condenses reveals effects="waterfall">
<app-toolbar>
<div main-title>Title</div>
<paper-button class="custom white" raised>Log Out</paper-button>
</app-toolbar>
</app-header>
<div id="loadcards"></div>
</body>
$("#loadcards").load("getGraph.php");
$(document).ready(function(){
setInterval(function(){
$("#loadcards").load("getGraph.php");
},5000);
});
Your page scrolls back to the top when you reload because your browser very briefly does not have any content for your div. This causes the content of your page to become too small to require a scrollbar, but when the content is reapplied it might grow large enough to require a scrollbar yet again.
Option 1
You could set the Y offset to the top of your page everytime before the reload is called, then scroll back to that offset whenever the page finishes reloading (or at least as far down as possible if the page is smaller than before).
You can obtain the current offset from the top of the window with the following code:
var offsetY = $(window).scrollTop();
If you want to scroll back to where you were before, you can do so by calling the following:
$('html, body').animate({
scrollTop: $(this).offset().top
}, 300);
This will gradually scroll, but you can set 300 to 0 if you want it to scroll instantly.
Depending on the efficiency with which your page loads, you'll probably still see a jump in the page contents.
Option 2
You can alternatively put your entire DIV inside a container with a fixed height, and reload the contents inside. You should set at least a min-height on the container div.
<div style="min-height: SOME_VALUE">
<div id="loadcards"></div>
</div>
Set SOME_VALUE to whatever comes closest to your actual page size. This should prevent the page jump as well, but will cause your page to have a minimal height even when the actual contents are smaller.
Option 3
The most advanced solution would be to use a container DIV and set the height to whatever the LoadPage height is just before you reload. This way it will only reset AFTER you reload your page.
<div id="cardscontainer" style="min-height: SOME_VALUE">
<div id="loadcards"></div>
</div>
With the following changes to your JS:
setInterval(function(){
$("#loadcards").load("getGraph.php");
$('#cardscontainer').height($('#loadcards').height());
},5000);
EDIT: I swapped the 2 functions inside the SetInterval callback function because it would result in weird behaviour if the LoadCards DIV would be smaller than before.
I want to make a scroll effect to my web page:
The content of my page:
<div id="first">
Content 1
Switch
</div>
<div id="second">
Content 2
</div>
Obviously, when I click to Switch, the browser screen will switch from div#first to div#second immediately.
However, I want to create an effect that make div#first to switch smoothly and slide to div#second (not immediately). Moreover, I also want to create a scroll effect. When the users are in div#first and scroll down, the browser screen will automatically slide to div#second and vice verse.
How can I do that with javascript (or jQuery if necessary)?
Yes, you can do that using animate method
$("a").click(function(){
$('html, body').animate({
scrollTop: $("#second").offset().top
}, 900);
})
Here is the Jsfiddle
Hope it helps :)
I was wondering if anyone knows if there was a javascript or something that scrolls a site left right up and down on a click.
For example I want to create a site with multiple divs. Look at photo below.
I want each div to fit to screen and div 1 being the main div, the starting point. Say that I had a link in the menu for biography and the content for biography was in div 4 and someone click biography, I want the site to move down to div 3 and then right to div 4 and the same thing goes for div 4 and all the divs. When someone clicks a link in the divs I want the site to scroll in a direction I specify, is this possible.
Left Right Up Down
The jquery animate function is the right way.
Here you can find a simple and clear tutorial on how to use it: http://gazpo.com/2012/03/horizontal-content-scroll/
The tutorial is for horizontal scroll only, but you can easily extend to scroll your page in both directions (vertical and horizontal at the same time).
Yes, they are:
.scrollLeft()
.scrollRight()
With jQuery, you can animate the body's scrollTop value to scroll up and down:
$("html,body").animate({
scrollTop: $("#bio").offset().top
}, 1000);
The above code will scroll to the element with the id of #bio.
In terms of scrolling sideways, I supposed you could use a little trick. Set the body's overflow-x to hidden to hide anything that overflows to the right of the browser viewport. Then you can adjust the margin-left of body to "scroll" to the right or left. But, of course, this removes the ability for users to scroll through all of your divs.
$("body").animate({
marginLeft: "-100%"
}, 1000);
you can use jquery animate function ,it will give you more control
$('#div').animate({
left: '+=50'
}, 5000, function() {
// Animation complete.
});

i'm trying to make a div drop down when someone hovers over a link. Inside the div is a login form. The following code works only in that if i hover over the link the div does appear. However when i move the mouse from the link down over the div, the div immediately retracts. Please see:
jQuery(document).ready(function() {
jQuery('.slidedown').hide();
jQuery('a.top-link-cart').hover( function(){ // enter animation
jQuery('.slidedown').stop(true,true).animate({
height: ['toggle', 'swing'],
}, 600, function() { /* animation done */ });
}, function(){ // leave animation
jQuery('.slidedown').mouseout( function() {
setTimeout( function(){
jQuery('.slidedown').stop(true,true).animate( {
height: '0px'}, 600, function(){});}, 200 ); // setTimeout ends here
}); // mouseout ends here
});
});
All i'm trying to achieve is have the div a) stay open if the user mouses from the link to the div b)close if the user moves mouse away from link but not into div and c) close if user moves mouse out of div. I thought the .mouseout function would keep the div open so that i can at least move my mouse over it but it isn't working. Any ideas? I'd be very grateful this has been a headache to me for a week now. Thanks.
You should not use .hover but .mouseover() instead for your first method.
You could wrap your link and the div that does the animation in another div and then apply the hover to the parent div instead of the link. This way you will still validate. For example:
<div class="whatever">
<a class="top-link-cart">Show login form</a>
<div class="slidedown">form html goes here</div>
</div>
and the javascript would be:
jQuery(document).ready(function(){
jQuery('.slidedown').hide();
jQuery('.whatever').hover(function(){//to show
jQuery('.slidedown').show('effect', duration in millisecs);
}, function(){//to hide
jQuery('.slidedown').hide('effect', duration in millisecs);
});
});
this uses the jQueryUI for the animation effects, but you could use the .slideDown() and .slideUp() methods as well if all you need is the div to slide up or down
You need to nest your div.slidedown inside the a.top-link-cart:
<a class="top-link-cart">Show login form
<div class="slidedown">
The login form HTML
</div>
</a>
Ignoring standards (block elements like <div> tags shouldn't really be nested inside inline elements like <a> tags), this will work because when the div.slidedown expands, so does the parent <a>.
That way, the mouseout event won't be triggered until the user's mouse leaves the <a>.
