I want to display images on a dojo chart. For this i use the following code
var l_images = ["images/clearnight.png","images/clear.png","images/partlyCloudy.png","images/cloudy.png","images/showers.png","images/rain.png","images/thunderstorms.png","images/ice.png","images/flurries.png","images/snow.png","images/partlyCloudynight.png"];
var d = new dojo.Deferred();
for(var i=1 ; i < conditionData.length-1 ; i++ ) {
var l_con_map = conditionData[i];
var l_image_id = "image"+i;
try {
dojo.create("img", {src: l_images[l_con_map.conditon]}, dojo.byId(l_image_id));
} catch(e) {
d.errback(e);
}
}
each l_image_id is a div with css. For example :
and the css is
.zdiv1css {
position:absolute;
top:240px;
right:0px;
left:190px;
width:200px;
}
It is working fine for IE9 and chrome but IE8 is not displaying any image.
Please help me out
Thanks in advance

add
z-index:999
as like this
.zdiv1css {
z-index:999;
}

Angular JS code I am working on has media queries that can be used to limit the display of blocks with code like this:
#media screen and (max-width: 370px) {
#testGrid {
.gridHeader {
div:nth-child(2),
div:nth-child(3),
div:nth-child(n+7) {
display: none;
}
div:nth-child(6) {
border-top-right-radius: 0.4rem;
}
}
.gridBody {
div {
div:nth-child(2),
div:nth-child(3),
div:nth-child(n+7) {
display: none;
}
}
}
}
}
My comment here was that it's not good to use things like div:nth-child(2) as this would easily break if another column was added. Plus it's also difficult to maintain. I suggested to give the column names class names that matched the contents of the columns.
Still this means that I have the code that defines what shows and what does not show far removed from the HTML. Does anyone have any suggestions on a way that I could do this with AngularJS that would have the showing and hiding of columns next to the actual <div>s
You can get the current width from the $window service so you could try something like this:
DEMO
app.controller('MainCtrl', function($scope, $window) {
$scope.name = 'World';
angular.element($window).bind('resize', function(){
$scope.hideThing = ($window.innerWidth < 400);
// have to manually update $scope as angular won't know about the resize event
$scope.$digest();
});
});
Then in your HTML
<body ng-controller="MainCtrl">
<p ng-hide="hideThing" >Hello {{name}}!</p>
</body>
I'm not sure if "sticky" is the term for this, but is there a way to make the scrollbar from overflow:auto stay visible?
I have a rather large table that I want to be scrollable horizontally; however, the table is fairly tall as well, so when the page loads the horizontal scrollbar is not within the viewport of the browser, so it's rather hard to tell that the table is scrollable at all.
<div style = 'width:900px;overflow:auto'>
<table>
<!-- Very large table here -->
</table>
</div>
The scroll bar appears below the table, but unfortunately the table is so tall you can't see it unless you scroll down.
I'd like to have the horizontal scrollbar stay visible even if the table goes off the screen, maybe fixed to the bottom of the viewport. Ideally I'd like to do it using only CSS or a minimal amount of javascript.
Here is a script for that http://jsfiddle.net/TBnqw/2288/
$(function($){
var scrollbar = $('<div id="fixed-scrollbar"><div></div></div>').appendTo($(document.body));
scrollbar.hide().css({
overflowX:'auto',
position:'fixed',
width:'100%',
bottom:0
});
var fakecontent = scrollbar.find('div');
function top(e) {
return e.offset().top;
}
function bottom(e) {
return e.offset().top + e.height();
}
var active = $([]);
function find_active() {
scrollbar.show();
var active = $([]);
$('.fixed-scrollbar').each(function() {
if (top($(this)) < top(scrollbar) && bottom($(this)) > bottom(scrollbar)) {
fakecontent.width($(this).get(0).scrollWidth);
fakecontent.height(1);
active = $(this);
}
});
fit(active);
return active;
}
function fit(active) {
if (!active.length) return scrollbar.hide();
scrollbar.css({left: active.offset().left, width:active.width()});
fakecontent.width($(this).get(0).scrollWidth);
fakecontent.height(1);
delete lastScroll;
}
function onscroll(){
var oldactive = active;
active = find_active();
if (oldactive.not(active).length) {
oldactive.unbind('scroll', update);
}
if (active.not(oldactive).length) {
active.scroll(update);
}
update();
}
var lastScroll;
function scroll() {
if (!active.length) return;
if (scrollbar.scrollLeft() === lastScroll) return;
lastScroll = scrollbar.scrollLeft();
active.scrollLeft(lastScroll);
}
function update() {
if (!active.length) return;
if (active.scrollLeft() === lastScroll) return;
lastScroll = active.scrollLeft();
scrollbar.scrollLeft(lastScroll);
}
scrollbar.scroll(scroll);
onscroll();
$(window).scroll(onscroll);
$(window).resize(onscroll);
});
It is a quick test rather than a complete generic plugin, but is a good start, I think
Here's my take, #user2451227's is almost perfect, but didn't work with nested overflowed elements and had a number of performance issues, so I rewrote it:
$(function($){
var fixedBarTemplate = '<div class="fixed-scrollbar"><div></div></div>';
var fixedBarCSS = { display: 'none', overflowX: 'scroll', position: 'fixed', width: '100%', bottom: 0 };
$('.fixed-scrollbar-container').each(function() {
var $container = $(this);
var $bar = $(fixedBarTemplate).appendTo($container).css(fixedBarCSS);
$bar.scroll(function() {
$container.scrollLeft($bar.scrollLeft());
});
$bar.data("status", "off");
});
var fixSize = function() {
$('.fixed-scrollbar').each(function() {
var $bar = $(this);
var $container = $bar.parent();
$bar.children('div').height(1).width($container[0].scrollWidth);
$bar.width($container.width()).scrollLeft($container.scrollLeft());
});
$(window).trigger("scroll.fixedbar");
};
$(window).on("load.fixedbar resize.fixedbar", function() {
fixSize();
});
var scrollTimeout = null;
$(window).on("scroll.fixedbar", function() {
clearTimeout(scrollTimeout);
scrollTimeout = setTimeout(function() {
$('.fixed-scrollbar-container').each(function() {
var $container = $(this);
var $bar = $container.children('.fixed-scrollbar');
if($bar.length && ($container[0].scrollWidth > $container.width())) {
var containerOffset = {top: $container.offset().top, bottom: $container.offset().top + $container.height() };
var windowOffset = {top: $(window).scrollTop(), bottom: $(window).scrollTop() + $(window).height() };
if((containerOffset.top > windowOffset.bottom) || (windowOffset.bottom > containerOffset.bottom)) {
if($bar.data("status") == "on") {
$bar.hide().data("status", "off");
}
} else {
if($bar.data("status") == "off") {
$bar.show().data("status", "on");
$bar.scrollLeft($container.scrollLeft());
}
}
} else {
if($bar.data("status") == "on") {
$bar.hide().data("status", "off");
}
}
});
}, 50);
});
$(window).trigger("scroll.fixedbar");
});
Usage: Add the class fixed-scrollbar-container to your horizontally overflowed element, then include this code. If the container is updated or changes in size, run $(window).trigger("resize.fixedbar"); to update the bar.
Demo: http://jsfiddle.net/8zoks7wz/1/
#Mahn - I made a small update to the following function:
$('.fixed-scrollbar-container').each(function() {
var container = jQuery(this);
if (container[0].offsetWidth < container[0].scrollWidth) {
var bar = jQuery(fixedBarTemplate).appendTo(container).css(fixedBarCSS);
bar.scroll(function() {
container.scrollLeft(bar.scrollLeft());
});
bar.data("status", "off");
}
});
The if statement looks if the container offsetWidth is smaller than the scrollWidth. Else you will also get a fixed scrollbar if the content happens to be smaller than the container. I did not like having a disfunctional scrollbar, hence this edit.
How about restricting the height of the containing div so it stays within the body? You could then have the table scroll within that div.
Working jsfiddle here: http://jsfiddle.net/fybLK/
html, body {height: 100%; margin: 0; padding: 0;}
div {
width:500px;
max-height: 100%;
overflow:auto;
background: steelblue;}
table {
width: 1000px;
height: 1000px;
color: #fff;}
Here, I've set the html and body to 100% height so that the containing div can be sized.
I would like to highlight a div when it's clicked.
Heres the example: www.spidex.org
On this website if you hover any of the navigation buttons a div on the top of the page is highlighted.
You may use jQuery for achieving this.
get jQuery here.
now consider that you have a div that you want to highlight on mouseover called item.
do this by adding an overlay div.
div.overlay{
opacity:0;
background:#000;
width:100%;
height:100%;
position:absolute;
top:50px;left:0;
}
then use jquery
jQuery(document).ready(function($){
$('.item').mouseover(function(){
$('.overlay').css({opacity:0.3});
});
});
You can change the appearance of elements when hovered using the :hover pseudo-class.
For example
div:hover {
color: red;
}
Secondly, you can change the text color via using the color property and the background color using the background-color property.
Both are shown below:
div:hover {
color: black;
background-color: white;
}
In your given example, when you hover over the primary navigation items in the super-header, then the body dims. I agree with your analysis that this is managed with some cover div of the body.
One cross-browser approach (using jQuery in this example) you might consider would be the following:
EXAMPLE HTML:
<div class="header">
Some Link
</div>
<div class="body">
<div class="body-content">
[ CONTENT HTML ]
</div>
<div class="body-cover"></div>
</div>
EXAMPLE CSS:
.body {
position: relative; /* container needs position */
}
.body-cover {
position: absolute;
top: 0px;
left: 0px;
background-color: blue;
/*
you could use a sligtly transparent background here,
or tween your opacity in your javascript
*/
}
EXAMPLE JavaScript:
// on dom ready
jQuery(function ($) {
// closures
var $links = $('.header a');
var $body = $('.body');
var $content = $body.find('.body-content');
var $cover = $body.find('.body-cover');
var sCoverHiddenCssClassName = 'body-cover-hidden';
var sCoverTweeningCssClassName = 'body-cover-tweening';
var sCoverShowingCssClassName = 'body-cover-showing';
// closure methods
var fMouseOver = function () {
// check to see if hidden (not already tweening or showing)
if ($cover.hasClass(sCoverHiddenCssClassName)) {
// check content, may have changed.
$cover.css({
height: $content.outerHeight(),
width: $content.outerWidth()
});
// animate or tween cover (do this however you want)
$cover
.removeClass(sCoverHiddenCssClassName)
.addClass(sCoverTweeningCssClassName)
.fadeIn(function () {
// when completed, mark as showing/visible
$cover
.removeClass(sCoverTweeningCssClassName)
.addClass(sCoverShowingCssClassName);
});
}
};
var fMouseOut = function () {
// check to see if visible (not already tweening or hidden)
if ($cover.hasClass(sCoverShowingCssClassName)) {
// animate or tween cover (do this however you want)
$cover
.removeClass(sCoverShowingCssClassName)
.addClass(sCoverTweeningCssClassName)
.fadeOut(function () {
// when completed, mark as showing/visible
$cover
.removeClass(sCoverTweeningCssClassName)
.addClass(sCoverHiddenCssClassName);
});
}
};
var fClick = function (e) {
// prevent default if needed for anchors or submit buttons
// e.preventDefault();
if ($cover.hasClass(sCoverHiddenCssClassName)) {
fMouseOver();
}
else if ($cover.hasClass(sCoverShowingCssClassName)) {
fMouseOut();
}
};
// init interaction
$cover.hide().addClass(sCoverHiddenCssClassName);
$links.each(function () {
// wire links
jQuery(this)
.mouseover(fMouseOver)
.mouseout(fMouseOut);//
//.click(fClick); // use click event if desired
});
});
JQuery UI is also gives an good option to quickly highlight div .
https://jqueryui.com/effect/
$( "#divId" ).effect( "highlight", 500 );
I have two CSS classes:
.class1 {
height: 100%;
width: 300px;
border: 1px none #B0B0B0;
position: relative;
display: inline;
left: 10px;
}
.class2 {
height: 100%;
width: 200px;
position: relative;
display: inline;
margin-left: 15px;
background-color: #00CCCC;
border-top-width: 1px;
border-right-width: 1px;
border-bottom-width: 1px;
border-left-width: 1px;
border-top-style: solid;
border-right-style: solid;
border-bottom-style: solid;
border-left-style: solid;
}
Now, as you can see, they're both set to display in a line (no line breaks in between elements). Which works correctly. But for some reason, ever since I set the display to inline, the Padding, the Positioning and the Margin CSS have all just stopped working. I can add a margin-left 10inches and nothing will happen. Same with padding and positioning.
Can anyone explain how to fix this?
Also, I have the relative position set on both classes, yet when viewing the page in a browser, .class2 over laps .class1 when its supposed to be just after .class1.
Any ideas?
EDIT:
Okay, so I've done a JSFiddle, but it seems to be playing up even more there....
Looks like the Width is not working....
here it is:
http://jsfiddle.net/zYbwh/1/
You need to use
display: inline-block;
instead. margin doesn't work with display: inline elements, however with inline-block it does. You can then have an inline element with margins and explicit widths/heights.
To make this work in IE7, add these two lines:
*display: inline;
zoom: 1;
It's horrible, but it works.
I know this is quite a late answer but I wrote a jQuery plugin which support padding on inline elements (with word breaking) see this JSfiddle:
http://jsfiddle.net/RxKek/
Plugin Code:
$.fn.outerHTML = function () {
// IE, Chrome & Safari will comply with the non-standard outerHTML, all others (FF) will have a fall-back for cloning
return (!this.length) ? this : (this[0].outerHTML || (
function (el) {
var div = document.createElement('div');
div.appendChild(el.cloneNode(true));
var contents = div.innerHTML;
div = null;
return contents;
})(this[0]));
};
/*
Requirements:
1. The container must NOT have a width!
2. The element needs to be formatted like this:
<div>text</div>
in stead of this:
<div>
text
</div>
*/
$.fn.fixInlineText = function (opt) {
return this.each(function () {
//First get the container width
var maxWidth = opt.width;
//Then get the width of the inline element
//To calculate the correct width the element needs to
//be 100% visible that's why we make it absolute first.
//We also do this to the container.
$(this).css("position", "absolute");
$(this).parent().css("position", "absolute").css("width", "200%");
var width = $(this).width();
$(this).css("position", "");
$(this).parent().css("position", "").css("width", "");
//Don't do anything if it fits
if (width < maxWidth) {
return;
}
//Check how many times the container fits within the box
var times = Math.ceil(width / maxWidth);
//Function for cleaning chunks
var cleanChunk = function (chunk) {
var thisChunkLength = chunk.length - 1;
if (chunk[0] == " ") chunk = chunk.substring(1);
if (chunk[thisChunkLength] == " ") chunk = chunk.substring(0, thisChunkLength);
return chunk;
};
//Divide the text into chunks
var text = $(this).html();
var textArr = text.split(" ");
var chunkLength = Math.ceil((textArr.length - 1) / times);
var chunks = [];
var curChunk = "";
var curChunkCount = 0;
var isParsingHtml = false;
//Loop through the text array and split it into chunks
for (var i in textArr) {
//When we are parsing HTML we don't want to count the
//spaces since the user doesn't see it.
if (isParsingHtml) {
//Check for a HTML end tag
if (/<\/[a-zA-Z]*>/.test(textArr[i]) || /[a-zA-Z]*>/.test(textArr[i])) {
isParsingHtml = false;
}
} else {
//Check for a HTML begin tag
if (/<[a-zA-Z]*/.test(textArr[i])) {
isParsingHtml = true;
}
}
//Calculate chunks
if (curChunkCount == (chunkLength - 1) && !isParsingHtml) {
curChunk += textArr[i] + " ";
chunks.push(cleanChunk(curChunk));
curChunk = "";
curChunkCount = -1;
} else if ((i == (textArr.length - 1))) {
curChunk += textArr[i];
chunks.push(cleanChunk(curChunk));
break;
} else {
curChunk += textArr[i] + " ";
}
if (!isParsingHtml) {
curChunkCount++;
}
}
//Convert chunks to new elements
var el = $($(this).html("").outerHTML());
for (var x in chunks) {
var new_el = el.clone().html(chunks[x]).addClass("text-render-el");
var new_el_container = $("<div/>").addClass("text-render-container");
new_el_container.append(new_el);
$(this).before(new_el_container);
}
//Finally remove the current element
$(this).remove();
});
};
Thats the problem you get when using templates, ive programmed a site in php, but the design is killing me.
So i try'd some rocket fuel for webdesigners.
And this is the problems i keep getting every step of the way...
Inline-block does not work for me, nothing works, becouse it is not my design and i dont know the setup.
Ive tryd doing the design myself, but i am out of time, i need a design yesterday.
I suggest you take what u need from the templates and delete everything else, that will schrink your problem, and save you time.
Try the following link in any web browser on your desktop and then try it on any mobile browser (tried it on Android, iPhone & iPad - all produce same problem) and can someone tell me why the first 'frame' (well original sprite position) is always displayed behind the animation?
http://24hours-in.lincoln.ac.uk/projects/mus/animate2.html
Thanks!
Solved it! (with a fudge)
var character = null;
var xOffset = 0;
function animate() {
if(xOffset < 360){
xOffset += 30;
} else {
xOffset = 0;
}
character = document.getElementById("character");
character.style.backgroundImage = "url('char2.png')";
character.style.backgroundPosition = xOffset + "px 0px";
setTimeout(animate,250);
}
function init() {
var character = document.createElement("div");
character.id = "character";
character.style.backgroundImage = "url('spacer.png')";
character.style.position = "absolute";
character.style.width = "30px";
character.style.height = "65px";
document.getElementById("stage").appendChild(character);
animate();
}
window.onload = init;
I figured it was using a background fallback of the original image because of the transparency. Therefore, instead of starting off with the background image, I started off by applying a 1px transparent PNG file (abut assigning the rest of the CSS ready for the char PNG) and when it comes to the animation, I then substitute the background image to the char.PNG version.
I am sure there are more elegant ways, but this does the job!
You know, to be honest, I don't know what causes the issue, but the issue is that the character background-image is static - that is to say, it's set in stone (via css).
A fix around your issue is to dynamically add the background-image using javascript. Here's your revised code.
CSS
<style type="text/css">
body {
padding: 0px;
margin: 0px;
}
#character {
position:absolute;
width:30px;
height:65px;
background-position: center center;
overflow: hidden;
}
</style>
Javascript
<script type="text/javascript">
var character = null;
var xOffset = 0;
function animate() {
if(xOffset < 360){
xOffset += 30;
} else {
xOffset = 0;
}
character.style.backgroundImage = "url('char.png')";
character.style.backgroundPosition = xOffset + 'px, 0px';
setTimeout(animate,250);
}
function init() {
character = document.getElementById("character");
animate();
}
window.onload = init;
</script>
HTML
<body>
<div id="character"></div>
</body>
