Div tag dynamic issues

Div tag dynamic issues - javascript

I had one centre box, but when its width or height changes, its header, footer, left-sidebar, and right-sidebar should all change accordingly.
The center box should always be in the middle of the page even if its width or height changes.
Here is my code:
<html lang="en">
<head>
<script src="jquery-1.10.1.min.js"></script>
<script>
var modified_width, modified_height;
function set_width_height(width,height){
var width_factor=width/1024;
var height_factor=height/768;
var scale_factor=(width_factor>height_factor)?width_factor: height_factor;
modified_width=width*scale_factor;
modified_height=height*scale_factor;
return {width:modified_width, height:modified_height};
}
$(document).ready(function(){
set_width_height(800,480)
/* var width2 = 1024 - modified_width;
var height2 = 768 - modified_height;*/
$("#id6").css({'width':modified_width, 'height':modified_height});
/*
$("#id6").css("width",modified_width);
$("#id6").css("height",modified_height);*/
// alert(modified_width)
width1 = (1024 - modified_width)/2;
height1 = (768 - modified_height)/2;
$("#id2").css("width",width1);
$("#id4").css("width",width1);
$("#id3").css("height",height1);
$("#id5").css("height",height1);
})
</script>
<style>
.inc {
position:absolute;
border:1px solid white;
}
#id1{
width:1024px;
height:768px;
}
#id2{
left:0;
top:0;
bottom:0;
width:20%;
height:100%;
background:red;

}
#id6{

background:black;
}
</style>

Automatic change image up to down on time

I need this code without clicking function. I need it with normal slideshow against time.
I mean image will change after 5 sec automatically.
var gallery = $('.content'),
height = gallery.height();
$('.arrow').on('click', function(){
var up = $(this).is('.up_arrow');
if (up) {
gallery.animate({'scrollTop': '-=' + height});
} else {
gallery.animate({'scrollTop': '+=' + height});
}
});
.content{
width:400px;
height:300px;
overflow:hidden;
border:1px solid #999;
}
.content img{display:block;}
.arrow{
display:inline-block;
padding:5px 15px;
background:#eee;
border-radius:3px;
margin:3px 0;
cursor:pointer;
border:1px solid #ddd;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="arrow up_arrow">UP</div>
<div class="content">
<img src="http://placehold.it/400x300?text=image+1">
<img src="http://placehold.it/400x300?text=image+2">
<img src="http://placehold.it/400x300?text=image+3">
</div>
<div class="arrow down_arrow">DOWN</div>

Like this?
var gallery = $('.content'),
height = gallery.height(),
scrollHeight = gallery[0].scrollHeight,
y = 0;
$(function() {
setInterval(function() {
y += height;
if( y >= scrollHeight ) {
y = 0;
}
gallery.animate({'scrollTop': y });
}, 2000);
});
.content{
width:400px;
height:300px;
overflow:hidden;
border:1px solid #999;
}
.content img{display:block;}
.arrow{
display:inline-block;
padding:5px 15px;
background:#eee;
border-radius:3px;
margin:3px 0;
cursor:pointer;
border:1px solid #ddd;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="content">
<img src="http://placehold.it/400x300?text=image+1">
<img src="http://placehold.it/400x300?text=image+2">
<img src="http://placehold.it/400x300?text=image+3">
</div>

View this example. Run with plunker
// Add your javascript here
$(function(){
var gallery = $('.content'),
height = gallery.height();
setInterval(function(){
gallery.animate({'scrollTop': '+=' + height},1000,function(){

parallax div jumps to the top of the page

I'm trying to create a parallax effect on a div but it jumps the the top of the page as i start scrolling. The top value is changes to 0 immediately
HTML
<div class="container">
<div class="top">
</div>
<div class="middle">
</div>
<div class="slider" id="rowSlider">
</div>
<div class="content">
</div>
</div>
JS
function parallax(){
var prlx_lyr_1 = document.getElementById('rowSlider');
prlx_lyr_1.style.top = -(window.pageYOffset / 2)+'px';
}
window.addEventListener("scroll", parallax, false);
CSS
.container{width:100%;}
.top{position:fixed; top:0; left:0; width:100%; z-index:1; background:#000; height:50px;}
.middle{width:100%; height:150px; background:red; width:100%; position:relative; z-index:2; margin-top:50px;}
.slider{width:100%; position:fixed; height:200px; background:orange; left:0; top:200px; z-index:3;}
.content{width:100%; position:relative; z-index:4; height:200px; background:blue; margin-top:400px;}
JSFIDDLE DEMO

Thanks to dann:
Initial position for .slider is 200px. solution is:
prlx_lyr_1.style.top = (200-(window.pageYOffset / 2))+'px';

USING iscroll
<script type="text/javascript" charset="utf-8" src="iscroll.js"></script>
<script type="text/javascript" charset="utf=8" src="cordova-2.1.0.js"></script>
var myScroll;
document.addEventListener("deviceready", onDeviceReady, false);
function scroll()
{
myScroll = new IScroll('.wrapper', { scrollX:false , scrollY:true});
}
----
----
function onDeviceReady()
{
scroll();
----
----
On scrolling,I just get the following
W/webview(3101): Miss a drag as we are waiting for WebCore's response for touch down.
PROBLEM:
It is is not scrolling.If at all it does after great effort on it but,it scrolls only once.I go back to the main page and return it does not scroll at all.
I have tried implementing the iscroll java script for my application as a remedial process for the CSS position:fixed that does not work in android 2 and 3 versions using cordova 2.1.0
Please,Guide me!!

This is answered here.
The concept was implementing with the tags such as <ul> and <li> within the <wrapper> and <scroller> div.
Excellent answer!

Jquery slideDown on Button Click

I'm looking to have a slide(down) toggle but would like the panel to line up neatly along the left edge of the button. I don't want to hard code margin, position, px, etc but want the slide down panel to always be "in relation" to (and relative) the (left bottom of) button.
What am I missing?
<!doctype html>
<head>
<script src='http://code.jquery.com/jquery-1.7.2.min.js'></script>
<style type="text/css">
.slideToggleBox{
float:left;
padding:8px;
margin:16px;
border:1px solid red;
width:200px;
height:50px;
background-color:blue;
color:white;
position:fixed;
left:-10.5px;
top:2.3%;
}
.clear{
clear:both;
}
</style>
</head>
<body>
<div class="clear">
<button id=slideToggle>slideToggle()</button>
<br/>
<div class="slideToggleBox">
slideToggle()
</div>
</div>
<script type="text/javascript">
$("#slideToggle").click(function () {
$('.slideToggleBox').slideToggle();
});
</script>
</body>
</html>

Try this code. Added a demo here
HTML
<div class="wrapper">
<button class=slideToggle>slideToggle()</button>
<div class="slideToggleBox">slideToggle()</div>
</div>
<div class="wrapper">
<button class=slideToggle>slideToggle()</button>
<div class="slideToggleBox">slideToggle()</div>
</div>
CSS
.wrapper{
float:left;
width:200px;
}
.slideToggleBox {
float:left;
border:1px solid red;
width:200px;
height:50px;
background-color:blue;
color:white;
margin-top: -1px;
margin-left:1px;
}
JS
$(".slideToggle").click(function () {
$(this).next().slideToggle();
});

How to replace a div container with javascript

I must have a little design in javascript.
I have a menu with 5 entrys and only 1 HTML-page.
So I will have a content-div and enabled and disabled different static content in it, each menu-entry is another content.
I tried with 5 divs and disable 4 of them and enable 1, but the element under each other means every div is like a - enabled or not, so the "content" is moving then.
Hope its understandable.
Here is the code so far:
<html><head><title>Des Einsame-Katerchen's kleine Homepage</title>
<style type="text/css">
a:link { font-weight:bold; color:blue; text-decoration:none; }
a:visited { font-weight:bold; color:blue; text-decoration:none; }
a:focus { font-weight:bold; color:blue; text-decoration:none; }
a:hover { font-weight:bold; color:blue; text-decoration:line-through; }
a:active { font-weight:bold; color:blue; text-decoration:none; }
h1:focus { background-color:red; }
h1:hover { background-color:silver; }
h1:active { background-color:green; }
</style>
<script>
function an(id)
{
document.getElementById('start').style.visibility = 'hidden';
document.getElementById('start').style.height = '0px';
document.getElementById('me').style.visibility = 'hidden';
document.getElementById('me').style.height = '0px';
document.getElementById('rpg').style.visibility = 'hidden';
document.getElementById('rpg').style.height = '0px';
document.getElementById('musik').style.visibility = 'hidden';
document.getElementById('musik').style.height = '0px';
document.getElementById('screens').style.visibility = 'hidden';
document.getElementById('screens').style.height = '0px';
document.getElementById(id).style.visibility = 'visible';
document.getElementById(id).style.height = '500px';
}
</script>
</head>
<body style=" " >
<div style="width=100%; text-align:center; border: 1px red solid; height:40px;">
<div style="float:left; width:100px;"><a href="#" OnClick="an('start')" >Startseite</a></div>
<div style="float:left; width:100px;"><a href="#" OnClick="an('me')" >Über mich</a></div>
<div style="float:left; width:100px;"><a href="#" OnClick="an('rpg')" >RPG-Chars</a></div>
<div style="float:left; width:100px;"><a href="#" OnClick="an('musik')" >Musik</a></div>
<div style="float:left; width:150px;"><a href="#" OnClick="an('screens')" >Knuddels-Screens</a></div>
</div>
<br>
<div id="start" style="border:1px red solid; width:500px; height:500px; overflow: visible; " >
a
</div>
<div id="me" style="border:1px red solid; width:500px; height:0px; overflow: visible; visibility: hidden; " >
b
</div>
<div id="rpg" style="border:1px red solid; width:500px; height:0px; overflow: visible; visibility: hidden; " >
c
</div>
<div id="musik" style="border:1px red solid; width:500px; height:0px; overflow: visible; visibility: hidden; " >
d
</div>
<div id="screens" style="border:1px red solid; width:500px; height:0px; overflow: visible; visibility: hidden; " >
e
</div>
</body>

Try
style.display = 'none';
It will stop affecting other elements place and layouting.

If you haven't already, I would recommend checking out jQuery for DOM manipulation: http://jquery.com/. In your case, the html() method, http://api.jquery.com/html/, or the hide() method, http://api.jquery.com/hide/.
Good luck!

Take a look at Tabtastic for a decent implementation of this.
