If I to develop the same kind of functionality with the using only jquery or canvas, does any have idea how can I implement this?
we are going to make an image splitting effect

I want to create battery indicator for a web app. I use the progress bar tag. The problem is that it starts from left to right and i want to be from bottom to top. The second problem is that JavaScript seems to not change anything. How to fix this problems? Note: I already read this answers: Progress Bar Fill Up Bottom-To-Top
and this which is not using progress tag:
How to show a vertical progress bar from bottom to top
navigator.getBattery().then(function(battery) {
battery.addEventListener('levelchange', function() {
document.getElementById('bat').innerHTML=((battery.level*100));
})
document.getElementById('bat').innerHTML=((battery.level*100));
});
progress#bat{
position:absolute;
top:5vh;
right:5vh;
height:90vh;
border:none;
background-color:black;
color:red;
}
<div class='window' id='battery'>
<p id='batLevel'>BatteryLevel</p>
<progress max='100' value="22" id='bat'></progress>
</div>
To resolve the "top to bottom" directional issue for the progress indicator, one solution would be to use CSS transforms in this way:
transform:rotate(90deg);
That would have the effect of rotating the <progress/> element to make the indicator track from top to bottom. You'd then flip the values of width and height to achieve the dimensions of an "upright battery".
Lastly, to cause the progress element to update with changing battery levels, you should set the value field on the bat element rather than innerHTML as you currently are to achieve automatic updates, like so:
navigator.getBattery().then(function(battery) {
battery.addEventListener('levelchange', function() {
/* Apply battery.level * 100 to value field to cause
bat element to update as expected */
document.getElementById('bat').value = battery.level * 100;
});
/* Apply battery.level * 100 to value field to cause
bat element to update as expected */
document.getElementById('bat').value = battery.level * 100;
});
progress#bat{
position:absolute;
top:5rem;
left:1rem;
border:none;
background-color:black;
color:red;
transform:rotate(90deg); /* rotation flips
perception of width and height */
height:4rem; /* height appears to be width */
width:9rem; /* width appears to be height */
}
<div>
<progress max='100' value="12" id='bat'></progress>
</div>
I have 2 Divs, side by side. By default, only the left one shows, and it centered in the page content horizontally. But when the user click's a button on the first div, it would slide to the left, and show the other div.
I already have the visibilty setup. But The problem is, I need my js to detect that the div's display:none attribute, and adjust the first div accordingly (float:left or float:right)
If possible, a fiddle would be nice also.
This should work for you if I got your problem completely:-
HTML
<div id="left">
<button onclick="showDiv()">Show</button>
</div>
<div id="right">
</div>
JS
function showDiv(){
var leftDiv = document.getElementById('left');
var rightDiv = document.getElementById('right');
leftDiv.style.float = 'left';
rightDiv.style.float = 'right';
rightDiv.style.display = 'block';
}
CSS
div{
width:200px;
height:200px;
background:gray;
margin:10px;
}
#left{
float:right;
}
#right{
display:none;
}

I need a full width (responsive) slider with fixed height and centered image ( the min width is 960px and people with a wider screens will see the rest of the image (the extra on the left and right)) and it needs to auto-rotate.
Now I got the html/css worked out, but my javascript is rubbish so i have no idea how to let the images slide. I've checked out a lot of Questions here but nothing seems to work. My image dimensions are 2300x350.
CSS:
body {
margin: 0 auto;
}
#slider_container {
width:100%;
height:350px;
overflow:hidden;
position: relative;
z-index: 1;
}
.image {
position:relative;
float:left;
height: 350px;
width: 100%;
overflow: hidden;
}
.image img {
position:absolute;
left:50%;
top:50%;
margin-left:-1150px;
margin-top:-175px;
}
HTML:
<div id="slider_container">
<div class="image">
<img src="images/header.jpg" />
</div>
<div class="image">
<img src="images/header2.jpg"/>
</div>
<div class="image">
<img src="images/header3.jpg" />
</div>
</div>
With this code the pictures come out nice in the middle on every screen but
how do I let it slide and autorotate? I guess the first image just needs to be replaced by the second so a z-index change? or + or - the width of one picture?
You need to only style the img tag if using flexslider. Try the fiddle link below. I have included four files for this.
jQuery 1.9.1
flexslider.css
jquery.flexslider-min.js
bg_direction_nav.png
jsfiddle
Please check this... http://www.jqueryscript.net/demo/Responsive-jQuery-Full-Width-Image-Slider-Plugin-responsiveSlides/ it is full width and fixed height slider and auto rotate. Here you have options to styling according to your needs
$(function(){
var p=$('#content').responsiveSlides({
height:450, // slides conteiner height
background:'#fff', // background color and color of overlayer to fadeout on init
autoStart:true, // boolean autostart
startDelay:0, // start whit delay
effectInterval:5000, // time to swap photo
effectTransition:1000, // time effect
pagination:[
{
active:true, // activate pagination
inner:true, // pagination inside or aouside slides conteiner
position:'B_R', /*
pagination align:
T_L = top left
T_C = top center
T_R = top right
B_L = bottom left
B_C = bottom center
B_R = bottom right
*/
margin:10, // pagination margin
dotStyle:'', // dot pagination class style
dotStyleHover:'', // dot pagination class hover style
dotStyleDisable:'' // dot pagination class disable style
}
]
});
});
For more modification please see jquery.responsiveSlides.js
I want this scan line effect to work properly. To reveal the text from left to right. As if the cathode-ray is burning it into the phosphors on the screen.
The idea is to slide across black rows, that have a transparent tip. Here is a 80% working demo.
The rightmost black .mask div in every row will not expand. It must.
I have tried to keep the right-most .mask div with a black background as inline-block and make it full width. I somewhat understand why the request does not work (width:100% pushes the other inline-blocks onto the next line, as is only proper), but there must be a way to get this full right hand side without hacking the widths in javascript.
.row {
font-family:'Courier New',Courier,monospace;
font-size:16px;
display:block;
height:auto;
width:100%;
min-width:20%;
position:relative;
margin-right:0px;
}
.mask {
display:inline-block;
width:auto; /* 100% does not work */
background:black;
white-space:pre;
}
this won't work on jsbin becuase it uses absolute positioning (unless you view the full screen demo).. but I provided it anyways for you to copy/paste it into your own browser http://jsbin.com/uteyik/12/.. below are the change highlights:
css:
.row {
..
position:absolute; /* changed to absolute */
}
.mask {
..
width:100%; /* changed to 100% */
position:absolute; /*changed to absolute */
}
and javascript:
jQuery(document).ready(function() {
function fill_box(rows) {
var rowHeight = getSampleRowHeight();
var thisRowHeight = 0;
for(var i = 0; i < rows; i += 1) {
$('.box').append('<div class="row" style="top: '+thisRowHeight+'"><div class="scan_cursor i1"> </div><div class="scan_cursor i2"> </div><div class="scan_cursor i3"> </div><div class="mask"> </div></div>');
thisRowHeight +=rowHeight;
}
}
fill_box(30);
function tag_animate(el) {
// animate the mask
el.animate( {
'margin-left' : '100%'
},
{
complete : function () {
tag_animate(el.parent().next().find('.mask'));
}
}
);
// animate the stripes
el.siblings().animate( {
'margin-left': '100%'
},
{
complete : function () {
el.siblings().hide();
}
}
);
}
tag_animate($('.box').find('.row').eq(0).find('.mask'));
function getSampleRowHeight() {
// get sample row height, append to dom to calculate
$('.box').append('<div class="row" style="display: hidden"> <div class="scan_cursor i1"> </div></div>');
var rowHeight = $('.row').height();
$('.box').find('.row').remove();
return rowHeight;
}
});
explanation: I first create a dummy row and calculate it's height. I then create rows that have position: absolute and position it from the top using the dummy row height x row number. the idea is that I wanted to make everything with absolute positioning so that the mask doesn't push the stripes below when it's 100%, also the row has to be absolute because as I make it's contents disappear, I don't want the rows below to jump up.
bonus: see it work the opposite way (ie the text disappearing): http://jsbin.com/uteyik/9 this was my initial (and incorrect) answer
I'm trying to develop a slide gallery with image tooltips according to this design:
What I need to develop is a slider controlled by two buttons, each time a button is pressed the slider's content must move a width of the slider or the width of the content left on that side, whichever is smaller. Upon mouse entering an image inside the slider the full-size version must be displayed as a tooltip.
Here's a fiddle of my solution so far, the problem I'm having is that images that don't fully fit into view plus the hidden area to the left get moved to a new line. You can see the problem by clicking the
"Show content size" button, the width of the content element will be equal to the width of the container element + content element's margin-left.
Bonus points if you can suggest an algorithm for moving the content to the right, I've got left figured out to a T (or so I think, anyway), but right is going to take a little more work (it doesn't check whether the end of the content has been reached). Update: It seems I can't implement proper movement to the right until the other issue is resolved, here's the algorithm I came up with, I can't measure "left to display" if I can't measure the actual width of the content element.
I created something you might like:
gallery demo
The gallery does not scroll the full gallery width by default (you can change that) cause some initially cut-off images at the right side, after a 'full' slide would result cut-off again, just on the other side of our gallery. You have for that cause the beKind variable. Adjust it as you like.
It hides the buttons if there's not enough content to make the gallery usable.
The gallery calculates the remaining space to scroll.
Once the slider end reached - the left/right buttons make the gallery jump to the beginning/end, so that are always usable. (Seems kinda weird to have a button... but that does nothing right? ;) )
The Tooltip has a hover-intent built in, to not piss off our users if they unintentionally hovered our gallery: (the tooltip fades in if the hover is registered for more that 120ms. Fair timing. I like it.)
As pointed out in your comment now the tooltip will not go off the screen.
jQ:
// Slide Kind Gallery - by roXon // non plugin v. // CC 2012.
$(window).load(function(){
var galW = $('#gallery').outerWidth(true),
beKind = 120, // px substracted to the full animation to allow some images to be fully visible - if initially partly visible.
sumW = 0;
$('#slider img').each(function(){
sumW += $(this).outerWidth(true);
});
$('#slider').width(sumW);
if(sumW <= galW){ $('.gal_btn').remove(); }
function anim(dir){
var sliderPos = Math.abs($('#slider').position().left),
rem = dir ==='-=' ? rem = sumW-(sliderPos+galW) : rem = sliderPos,
movePx = rem<=galW ? movePx = rem : movePx = galW-beKind;
if( movePx <= 10){
movePx = dir==='-=' ? movePx=rem : movePx = galW-sumW;
dir = '';
}
$('#slider').stop(1).animate({left: dir+''+movePx },1000);
}
$('.gal_btn').on('click', function(){
var doit = $(this).hasClass('gal_left') ? anim('+=') : anim('-=');
});
});
And the tooltip script:
// Addon // Tooltip script
var $tt = $('#tooltip');
var ttW2 = $tt.outerWidth(true)/2;
var winW = 0;
function getWW(){ winW = $(window).width(); }
getWW();
$(window).on('resize', getWW);
$('#slider img').on('mousemove',function(e){
var m = {x: e.pageX, y: e.pageY};
if( m.x <= ttW2 ){
m.x = ttW2;
}else if( m.x >= (winW-ttW2) ){
m.x = winW-ttW2;
}
$tt.css({left: m.x-ttW2, top: m.y+10});
}).hover(function(){
$clon = $(this).clone();
var t = setTimeout(function() {
$tt.empty().append( $clon ).stop().fadeTo(300,1);
},120);
$(this).data('timeout', t);
},function(){
$tt.stop().fadeTo(300,0,function(){
$(this).hide();
});
clearTimeout($(this).data('timeout'));
});

Hope you'll like it, and you learned some useful UI design tricks.
By the way, if you want to populate your ALT attributes (Search engines like it!) you can also grab that text and make it appear inside the tooltip like here!:
demo with text inside the tooltip
Happy coding.
I don't know if I understand correctly your problem. If you set a width wide enough to .scroll-content div, images wouldn't go to the "next line". So a solution would be to set a width with css. If not, you could use jquery to determine the total width of all the images and give it to the .scroll-content div. Calculate total width of Children with jQuery
