I've been looking around for answers and everything I apply to my own code doesn't seem to work. I have a DIV with content. When I click on a link the DIV fades out, the content changes via the jQuery .html event and then the DIV fades back in. This gives the illusion of a gentle page change on my site. This DIV has a jScrollPane which works fine before any links are pressed.
What is happening however is that the scroll pane 'draggable area' stays the same size when the content is re-written and there is more or less, or even if there is no need for one at all.
I need to get the scroll pane 'draggable area' to change size in relation to the new content and I need it to scroll back to the top inbetween the .fadeTo fade out and in effect.
I've tried some of the following:
function showhome() {
$('#infohome').stop(true,true).fadeTo(100,0)
$('#infohome').delay(100).html("NEW CONTENT")
$('#infohome').stop(true,true).delay(200).fadeTo(100,1)
refreshNav();
function refreshNav() {
var element = $('.scroll-pane').jScrollPane({scrollToY(0, animate)});
var api = element.data('jsp');
}
As well as:
myJScrollPane.getVerticalScrollbar().setValue(int Pos);
and a few others.
As always, any help would be greatly appreciated.

So in my site, when a button is clicked,I dynamically generate a div, which contains a grid of images. It goes like this:
$('.prod-images').click(function(){
var prodImages = generateProdImagesGrid(this);
$('#prod-images-grid').html(prodImages).show();
});
This works fine. And I have another button which will close this div on click.
Now this div can be taller than the screen and require vertical scrolling. The problem is that because of all the CSS/styles in this page, this div always opens only at the scroll position where it was closed. So when I open it first time, it is scrolled to the top and everything is fine. Now, suppose I scroll this div halfway down and then close it. Next time when it is opened, it opens at that scroll position.
I tried doing:
$('#prod-images-grid').html(prodImages).scrollTop(0).show();
This does not work (at least in chrome) because the div is not fully rendered when the scrollTop() call is executed.
The only way I can make this work is to give a long delay between the div rendering and the scrollTop call like so:
$('#prod-images-grid').html(prodImages).show();
window.setTimeout(function(){
$('#prod-images-grid').scrollTop(0);
},10000); //call scrollTop after 10 seconds
As you can imagine, this is not at all a good solution. Does anyone have any suggestions on how I can render the div so that when its visible, it is scroll to its top position?
Doing:
$('#prod-images-grid').html(prodImages).scrollTop(0).show();
means that it's the <div id="prod-images-grid"> which gets scrolled; since this div has no content, it cannot be scrolled.
Rather do:
$(document).scrollTop(0);
$('#prod-images-grid').html(prodImages).show();
The 0 argument of scrollTop can of course be modified to point to the position of the document where you want your dynamically generated div to show.
You can handle a function after the contents is showing whith this propety of .show():
$( ".target" ).show(interval, handler);
Like this:
$('#prod-images-grid').html(prodImages).show(1, function() {
$('#prod-images-grid').scrollTop(0);
});
(you can change 1 for any other value)
I have gone through all related questions. But didn't find any answer.
My question is i have scrollable div tag, a chat window, in which images can be dropped as well. I have span tag at the end of every message so using this code the div tag scrolls properly to the bottom.
var EndChat = $(myid);
var chat_target = EndChat.find('span').last();
EndChat.scrollTo(chat_target, 1000);
But When i append Image after resizing it, It doesn't get to the bottom. It stop at 1/4th of the image.
And when the chat loads in the beginning, if there are many images, the scrolling stops even more far from the bottom. Please Help
Why don't you scroll to the bottom of the chat using:
EndChat.scrollTop(EndChat[0].scrollHeight);
It works: http://jsfiddle.net/shawn31313/mb6JA/
In order to make sure the images have loaded before scrolling, attach an event to the load, something like this:
$('.chat img').on('load', function() {
var chat_target = EndChat.find('span').last();
EndChat.scrollTo(chat_target, 1000);
});
If I'm not mistaken, whenever an image in .chat is loaded, it'll trigger the scroll to the footer. You could modify it as necessary :)
I installed jScrollPane on my website and can't make it work.
My website works as follows: from the main page, pages are loaded dynamically using jQuery's load() method. In the page I load I have the following script to launch jScrollPane:
$(function(){
$('.scroll-pane').jScrollPane();
});
Which seems to be called. No problems so far I guess. The problem is that the page, at the beginning, is not long enough to need a scrollbar. I have hidden content that shows up only on specific actions (i.e. clicking on a button shows the content of a certain paragraph), and when I click to show the content of a hidden div, the scrollbar doesn't appear.
I also tried to call $('.scroll-pane').jScrollPane(); as I show the new content (i.e. in the event that triggers .show() on the hidden div I also call $('.scroll-pane').jScrollPane();) but I had no success with that either.
Can anyone help me?
Thanks
EDIT:
I forgot to mention the structure of the page: I have a div which has class="scroll-pane" and is loaded with the page load and it contains small hidden divs that show up when clicking on particular areas. I would like to add a scroll bar to the div with the class scroll-pane in order to make the content of the showed div scrollable (right now the content stays in the size of the div but it's not scrollable since no jScrollPane scroll bar is shown).
Update:
I tried to put $('.scroll-pane').jScrollPane(); in the callback of the .show() method of my divs and tried to put class="scroll-pane" to those divs that appear, but again nothing is shown (the scroll bar doesn't appear and the div is not scrollable).
Check this demo provided by the developer of the plugin
http://jscrollpane.kelvinluck.com/examples/invisibles.html
When the element is first shown you simply have to (re)initialise the
scrollpane (or you could even use autoReinitialise if you like) and
its width and height will be calculated correctly.
All that you need is
$(function(){
$('.scroll-pane').jScrollPane({autoReinitialise: true});
});
and may be the recent version of the plugin
I suggest to use css visibility property instead auto reinitialising. Each time you call show() method, jScrollPane reinitialises itself. This takes time and has impact on animation.
If you use, say, slide..() methods, then animation starts properly, but scrollable container (and its elements) appears little bit later, and that looks bad.
var wrapper = jQuery('#gallery-album-preview-wrapper');
if (wrapper.css("visibility") == "hidden") {
wrapper.css("visibility", "visible").css("display", "none");
}
if (wrapper.is(":hidden")) {
wrapper.slideDown(1000);
} else {
wrapper.slideUp(1000);
}
i'm trying to slide a div element from outside the page to within the page. However as soon as the element is shown outside the page, horizontal scrollbars appear!
How can I achieve this without the scrollbars appearing?
Any help appreciated very muchly, thanks :)
Briefly, using overflow-x:
function moveStuff() {
$('body').css('overflow-x', 'hidden');
$('#iteminmotion').show().animate(..., function() {
$('body').css('overflow-x', 'auto');
});
}
move the element off the page to the left, moving it off to the right increases the width of the page
You could temporarily turn off side scrolling by applying this css to the body:
body {overflow-x:hidden;}

Do you really need to construct the element off page, or just make it look like it slides onto the screen? Ive done similar things in the past to emulate a graphic that slides across a page, but instead of starting outside the view area I've created it as far to the side as possible and then animated the slide to the middle. The user experience at that point can be a graphic that slides onto a page from outside the view area.
I am currently learning jQuery. I'd like to know how to make an image slide in when you click on its edge, then click again and it slides away. Similar to this:
http://www.karenmillen.com/
If you see the right hand side and click, there is the effect that i'm looking for. I assume this will involve making a div and giving it a background image then using some jquery to make the div slide into view. Of course the div could have other content such as html. Any ideas?
Would the .slideDown() method work?
if you want a div to slideDown() first it has to hidden.
so use $("#div_Id").hide();
after that use $("#div_Id").slideDown('slow');
this will work
Check out slideToggle
Here's what i have so far:
$(document).ready(function() {
$('.inner').hide();
$("button").click(function() {
$("#static_image").hide();
$('.inner').slideToggle(300);
});
});
So basically the animated div begins hidden. There's another div with a background image that is lined up to look as if the animated div is still sticking out a bit. Then clicking a button makes the static div dissapear and the animated div slide into view. However i'm not sure how to make the timing perfect so it's smooth and people won't know there are two divs. The animated div takes a fraction of a second to move up to where the div with the static image was, however the static images disappears immediately leaving a non-smooth animation.
One other thing, how do i get the static image div to return at the moment that the animated div moves back down after a user click? It can't be at the exact moment the user clicks 'retract' button else it'd definitely appear before it's supposed to.
In order to use the animate() function add a CSS class to the <div> tag that has a height attribute, it can either be in pixels or %, this will be the initial height. After that then you can use the animate().
$('#mydiv').animate({
height: 500px
}, 5000, function() {
// Animation complete.
});
This will slide the div to 500px, which will take 5 seconds.
