I have a need to display a lot of image thumnails in a small space.
My idea is to have 3 columns of thumbnails with an undetermined amount of rows. I planned to put this content in a and then put that inside a viewport div. Like so:
<div id="viewport" style="width: 300px; height: 300px; overflow: hidden;">
<div id="content" style="width: 300px; height: 100000px;">
Rows of thumbnails go here
</div>
</div>

Autotrader's image control is exactly what I am going for if an example helps illustrate my point.
I think what I need to do is change the topMargin of 'content' over a period of time with javascript for a scroll effect when one of the buttons is clicked.
I don't mess with javascript much and I'm not sure where to start. Can someone point me in the right direction?
So I finally took 30 seconds out of my day and learned what jQuery is and how to use it.

This is a simple example doing the movement I was looking for.
You have to download jQuery to make it work. http://jquery.com/
I'll leave the question up in case anyone else needs something like this.
<script src="../jquery-1.4.2.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#next").toggle(function() {
$("#content").animate({ marginLeft: '0px'}, 'slow');
}, function() {
$("#content").animate({ marginLeft: '-100px' }, 'slow');
});
});
</script>
<div id="viewport" style="width: 300px; height: 300px; overflow: hidden;">
<div id="content" style="width: 300px; height: 100000px;">
Rows of thumbnails go here
</div>
</div>
<a id="next" href="">Previous</a>
<a id="prev" href="">Next</a>
If there is a better way, let me know....

I have created a chatroom which elements are li. I want it to always stick to the bottom. It works fine when number of chats are like 10-20 but after that it stops halfway. I think there is something wrong with the height but I can't figure it out here is my html :
<div id="chat-main">
<ul id="chat-list">
//I dynamically add <li>s using ajax
</ul>
</div>
<div id="message-panel">
<form class="form-inline" id="messageForm">
<input id="message-value" type="text" autocomplete="off" maxlength="510" placeholder="Type your message...">
</form>
</div>
Here is my css:
#chat-main {
height: 84%;
border: 2px solid #d8d7cf;
}
#chat-list {
height: 100%;
overflow-y: scroll;
}
#chat-main>ul {
padding-left: 10px;
list-style-type: none;
}
And this is the jquery code for scrolling:
$("#chat-list").animate({ scrollTop: $(document).height() }, "slow")
I'm really stuck and don't know what is wrong.
Edit: here is my jsfiddle sorry for the chat objects I inserted alot so you can see what happens :
http://jsfiddle.net/L8msx/19/
Using document height doesn't seem logical, this will get the exact overflow of the chat :
http://jsfiddle.net/1yLzkgw8/
var chat = $("#chat-list"),
overflow = chat[0].scrollHeight-chat.height();
chat.animate({scrollTop: overflow}, 'slow');
When getting scrollHeight, plain JS is used so the DOM node itself is retrieved with [0].
I am making a web app. I have created 25 divs.
I have Used jquery fadeIn() by which divs are gradually made and displayed one after another on screen.
But problem is that when 25 divs have been created, scroll is created due to which first 4 divs can be seen but the remaining can't be seen until user scroll the page.
I want that as one by one div is created, the page should automatically scroll to the div recently created and so on this process should be continued until the last div is created.
You can use
$('html,body').scrollTop($(".answer.visible:last").offset().top);
$(function() {
$(".answer").hide();
$('#demo').click(function(e) {
var _div = $('.answer[style*="display: none"]:first');
if (_div.length) {
_div.fadeIn();
$('html,body').animate({
scrollTop: _div.offset().top
},
'slow');
} else {
$(this).text('Done..!');
}
});
});
#demo {
position: fixed;
bottom: 0px;
left: 0px;
}
.answer {
width: 100%;
height: 200px;
border: 1px solid black;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="demo">Click here</button>
<div class="answer">1</div>
<div class="answer">2</div>
<div class="answer">3</div>
<div class="answer">4</div>
<div class="answer">5</div>
<div class="answer">6</div>
<div class="answer">7</div>
<div class="answer">8</div>
<div class="answer">9</div>
<div class="answer">10</div>
<div class="answer">11</div>
<div class="answer">12</div>
<div class="answer">13</div>
<div class="answer">14</div>
<div class="answer">15</div>
<div class="answer">16</div>
<div class="answer">17</div>
<div class="answer">18</div>
<div class="answer">19</div>
<div class="answer">20</div>
<div class="answer">21</div>
<div class="answer">22</div>
<div class="answer">23</div>
<div class="answer">24</div>
<div class="answer">25</div>
I think this looks pretty cool when we use slideDown+scrollTop. Check fiddle
Documentations
To get the coordinates
http://api.jquery.com/offset/
Set vertical position of the scroll bar
https://api.jquery.com/scrollTop/
Set horizontal position of the scroll bar
https://api.jquery.com/scrollleft/
I found this link here
smooth auto scroll by using javascript
Using this you could create something like this here:
http://jsfiddle.net/mrc0sp5j/
The main point is, that you create a scrolling-function using
window.scrollBy or window.scrollTo
http://www.w3schools.com/jsref/met_win_scrollto.asp
With jQuery .last or .eq you can specify which element you want to scroll to
$(".mydivobjects").eq(x).position().top
Hope this helps

HTML:

<head>
<script type="text/javascript" src="jscript/jquery.js"></script>
</head>
<body>
<div class="slider_b">
<img src="img/frame_wood_back_460_380.jpg">

<script>
setInterval("switchit()", 3000);
$('.slider_b img:gt(0)').hide();
function switchit() {
$('.slider_b img:first-child').fadeOut(0).next('img').fadeIn(2000).end().appendTo('.slider_b');
}
</script>
</body>
</html>
CSS:
.slider_box img{
position:relative;
top:0px;
left: 0px; }
.slider_box {
position:absolute;
width: 480px;
height: 360px; }
#button {
position: relative;
top: 10px;
left: 500px;}
The slideshow works - I just could not figure out how to switch the slideshow to one of the images by clicking a thumbnail button (id=button) - the slideshow should continue then in the regular circle order.
You could add a data attribute to your <img> elements, and append the button with the first child <img>element to carry over that data attribute. e.g:
<img src="" data-slide="1">
And for the append
var thumbnail = $("div.slider_b").find("img:first");
$("#button > img").replaceWith(thumbnail);
Once this is done, make it so that
("#button").on(click, function() {
var moveTo = $(this).find("img").data(slide);
var item = $("div.slider_b").find("[data-slide='" + moveTo + "']"
$("div.slider_b).prepend(item);
}
I'm not 100% right with the jQuery, but I believe I'm on the right lines. A bit more exploration down this route will get you to where you need to be.
Try making a relation between the slide and its thumbnail to fetch the respective slide, e.g. by using attibutes pairs, like data-slide="slide1" for the thumbnail and id="slide1" for the actual slide
on thumbnail click, adjust the current slide to the respective one and continue auto animation from this point
Point one is just one solution, it's the creativity part ;) You could come up with something else, like e.g. using thumbnails and slides indexes, etc. Good luck.
+++++i add mention+++++
thanks guys for your answers,
but, i think, i missed something to write more.
when i click the button to show the div(#pop), it works right at the scroll on the top.
but, when i go down the scroll, the div(#pop) goes up in the window(height:0) not in "bottom:10%" like at the scroll on the top.
so, i'm trying your answers now, but, i'm not succeed yet T_T HELP!! :)
=================================================================================
Here are my codes.
I have a floating menu and one button of them works for showing a div id = pop, which is floating too.
I want to hide the div #pop when window starts, and when the button's clicked, it shows.
So I added codes display:none to hide, but when i click the button to show the div #pop, the div #pop is anywhere, not in bottom: 10% in CSS.
HTML
<div class="menu">
<img src="btnUp.png"><br/>
<img src="btnMe.png" id="pop_bt"><br/>
<a href="#scrollbottom">
<img src="btnDown.png">
</a>
</div>
<div id="pop">
<div>
POP UP
</div>
</div>
CSS
#pop{
display: none;
width: 300px;
height: 400px;
background: #3d3d3d;
color: #fff;
position: absolute;
bottom :10%;
left: 30%;
z-index: 3;
}
Javascript
$(document).ready(function(){
var boxtop = $('.menu').offset().top;
$(window).scroll(function(){
$('.menu').stop();
$('.menu').animate({"top": document.documentElement.scrollTop + boxtop}, 800);
});
});
$(document).ready(function() {
$('#pop_bt').click(function() {
$('#pop').show();
});
$('#pop').click(function() {
$('#pop').hide();
});
});
$(document).ready(function(){
var boxtop = $('#pop').offset().top;
alert(boxtop);
$(window).scroll(function(){
$('#pop').stop();
$('#pop').animate({"top": document.documentElement.scrollTop + boxtop}, 800);
});
});
Actually, I'm not a programmer, just a designer, so I'm very fool of HTML/CSS/Javascript.
Can anyone help me?
Display none is removing your button from the layout.
Same on .hide().
Use opacity 0 to hide the dig but keep it in your browser.
In the absence of a fiddle, I can do some guess work only. Looks like the line below is the problem:
$('#pop').animate({"top": document.documentElement.scrollTop + boxtop}, 800);
It sets a top value and moves the layer to some other place. It should work fine if you remove that.
use this...
$(document).ready(function()
{
$("#pop").hide();
$("#button_id").click(function()
{
$("#pop").show();
});
});
is this you actually need?
I have spent the last two days looking for a simple javascript or jquery code for this. I want to incorporate a horizontal scrolling div using javascript or jquery to display images and descriptive text for the work page of my web portfolio.
It would function very similar to the glide-onclick scrolling shown here: http://www.dyn-web.com/code/scroll/demos.php#horiz Unfortunately that code license is $40, and I am a broke student.
On loading of the page, three portfolio images will be shown. Extras are hidden in the overflow to the right. Onclick of a left arrow (I can create), a new image slide comes into view from the right. A right arrow click sends it back into overflow. I don't want scrollbars, just arrows controlling the slides.
Any help is much appreciated. Thanks.
You can just use code like this:
function FixMargin(left) {
$(this).css("left", left);
}
$(document).ready(function () {
$('#rightbutton').click(function () {
var left = parseInt($("#bitToSlide").css('left'), 10);
$("#bitToSlide").animate({ left: left - pageWidth }, 400, FixMargin(left - pageWidth));
});
$('#leftbutton').click(function () {
var left = parseInt($("#bitToSlide").css('left'), 10);
$("#bitToSlide").animate({ left: left + pageWidth }, 400, FixMargin(left + pageWidth));
});
}
where your html looks like this:
<div id="slideleft" class="slide">
<div class="inner" id="bitToSlide" style="width:1842px">
<table border="0" cellpadding="0" cellspacing="0">
<tr valign="top">
<td id="page1" style="width: 614px">
</td>
<td id="page2" style="width: 614px">
</td>
</tr>
</table>
</div>
</div>
and your css looks like this:
.slide
{
position:relative;
overflow:hidden;
height:365px;
width:597px;
margin:1em 0;
background-color:#E9ECEF;
border:0px
}
.slide .inner
{
position:absolute;
left:0;
bottom:0;
height:365px;
padding:0px;
background-color:#E9ECEF;
color:#333
}
I wrote the above a really long time ago - so you probably want to update it a bit (replace the table's with div's for example) but it works.
You obviously need the two buttons on there as well
There are a lot of jQuery plugins which allow you to do this very easily.
For ex: http://slidesjs.com/
Hope this helps.
You can do something like this. Not tested code but just giving you a hint.
<div id="imageContainer">
<div id="imageWrapper">
<img />
<img />
</div>
<span id="left">Left</span>
<span id="right">right</span>
</div>
var imageWidth = 200;
$("#left").click(function(){
$("#imageWrapper").animate({marginLeft:"-="+imageWidth}, 500);
//Offcourse you need to handle the corner cases when there is not image to move left
});
$("#right").click(function(){
$("#imageWrapper").animate({marginLeft:"+="+imageWidth}, 500);
});
You can have a look to iscroll 4.
http://cubiq.org/iscroll-4
You have a scrollTo method or scrollToElement method...
