First, have a look there and click on the switch (Incoming/Right Now): https://ilovesubiaco.com.au/events-search/
As you can see my switch is working, but on my "Right Now" events, my Tiles are stacking up on each other.
The reason is that my elements.style for the main div of each (col-lg-3 col-sm-4 col-xs-12 masonery_item event-now-tile) is not calculating the left properly as it should, probably because my tiles are not displayed when my html is loaded.
I ran some test trying to remove the first "fadeOut(0)" to see if I could tweak it.
In that case, my tiles have the right % left per element but the issue is that my tiles are still taking up white space after display none.
I also tried to reload my div with the JS ".load" but it doesn't look good so I may not know how to use it properly.
How do I force the BootStrap library to recalculate my div Left:%; space when I switch for the first time?
Here is my JS:
jQuery(document).ready(function(){
$(".event-now-tile").fadeOut(0);
$('#event-inc-now-switch').on('switchChange.bootstrapSwitch', function (e, data) {
var state=$(this).bootstrapSwitch('state');//returns true or false
if(state){
$(".event-now-tile").fadeOut(500);
$(".event-inc-tile").fadeIn(500);
}else{
$(".event-inc-tile").fadeOut(500);
$(".event-now-tile").fadeIn(500);
}
});
});
Thanks !!
The solution was pretty simple, replace the position of my tile
.event-now-tile{
position:relative !important;
}
It's the way display is set with the fades with jQuery. Any dives which have a certain %value are stacked on each other if the display of them is set to Absolute.
I have been helped by #Davidkamer on the JS chat for this answer. Thanks to him!

I am using html2canvas library for converting a div to png.
I have an issue about z-index. As you can see on image, I have boxes. Inside a box I have a div for background coloring (z-index: 0), its growing with height value and a div for number (z-index: 1). It works fine on browser as usual but when I try to take image, it seems like z-index doesn't work.
normal on browser:
issue on image version:
Any help, I will be grateful.
Have you checked this: for z-index to work correctly, every element that has one must also have a position set ( e.g.position:relative )...
I got the same issue. And I found out that html2canvas ignores z-index and just follows the order of div when it draws div to img. For example,
<div id=1 zIndex=2></div>
<div id=2 zIndex=3></div>
<div id=3 zIndex=1></div>
If all these divs are overlapping, divid2 comes forward then divid1 and divid3 in webpage since it cares about the zIndex.
html2canvas only cares about the order of divs ignoring zIndex which means divid1 comes forward and divid2 comes behind divid1, and divid3 comes behind div2. I tested multiple times.
I hope it would be helpful.
I had to add position:"relative" to every element at the same level as my images.
Try the following steps and see if one of them works for you:
Try to put high z-index values for different divs. Example: .div1 {z-index:1} .div2{z-index:10000).
Try to every div that you defined a z-index, define a position to him.
Try put the div's with greatest z-index value with position absolute/fixed.
If you are testing it in localhost, You can do so by passing one of the options in the html2canvas function.
html2canvas(document.body,
{
useCORS: true, //By passing this option in function Cross origin images will be rendered properly in the downloaded version of the PDF
onrendered: function (canvas) {
//your functions here
}
});
I'm working with a jquery and I have this image that is the main problem. I googled it but came up with nothing. Here is my content for example.
And when the guy(in the picture above) is being click I want it to slide to the left side and will looked like this. Please see image below.
So what I'm thinking is
1. using addClass and removeClass using jquery or
2. just use jquery .slide or toggle function?
If there's a solution as such how could it be done? Since I only know is using addClass tho. And also what I'm planning is when the image exceeds 800px then the girl(in the image) will be send to back of the guy image.
What you are trying to do is create a mask around the guy. The scope of this question is beyond masking. Most methods of masking don't have large browser support at this moment so posting more on this would be disingenuous. But worth googling otherwise you can use the transform property to move the picture to the left. But you won't get the results you are looking for..
But there is the option of masking the picture in Photoshop and saving it as a PNG. And then utilizing the translate CSS method to move the image to left. This is your best option. But the details of either of these methods are out of scope for this question.
Cut this guy from image and put in another div at needed position. Put blue box between those two images and use slide function. You can cut the guy from his head i think.
Basically you need to have an html structure like this:
<div id='container'>
<div id='couple'></div>
<div id='mask'></div>
</div>
Initially in your css:
#mask {
display: none;
}
And, of course, you have to align horizzontally this two div.
Your jquery will have a behavior like this:
$('#couple').on('click', slide);
var slide = function() {
$target = $('#container');
$mask = $('#mask');
$mask.fadeIn();
$target.animate({
left: "+=50"
}, 500, function() {
/* callback on end*/
});
}
For complete documentation of animate check api jquery.
I'm trying to build a content slider for a client that displays their last four posts. Right now it's just plain HTML but I'm having a problem.
The slider box needs to be 180px high with a scrollbar when necessary. My slider seems to work except it makes the slide boxes all as tall as the tallest box. That leaves short posts with a ton of blank space under them.
Anyone know a fix?
http://jsfiddle.net/insitedesignlab/kQDcb/1/
I've seen that Quovolver does this, but I'd love to know how
The basic problem is #slidesContainer needs to be dynamically resized in order for it's parent to know how long to scroll for. One way to solve the problem is to change your animate call to include a callback:
$('#slideInner').animate({
'marginLeft' : slideWidth*(-currentPosition)
},null,null,
function(){
$('#slidesContainer').css('height', $(this).children(".slide:nth-child(" + parseInt((Math.ceil(-1*slideWidth*(-currentPosition) / $("#slideshow").width())) + 1) + ")").height() + "px");
}
);
There's probably a slightly better way to make that calculation, but this will work. You could alternatively hide all the other .slide divs that are not being displayed. Then #slidesContainer will auto-resize to only the visible (not display:none) slide.
I have updated your code here JS Fiddle. You need to remove the min-height property and set the background color to the slide div.
Problem in brief
I have got a piece of working two dimensional scrolling code. Scrolling as such is working fine. Scrolling can be done in any direction (not like restricted to only horizontal or only vertical at a ti,e) but there are two problems -
Scrolling beyond the visible area towards top and left, does not bounce back the scrollable area.
Scrolling to right and bottom bounces back.
Problem demo - http://jsfiddle.net/sandeepan_nits/pAhjU/6/
Note - Test in webkit browsers only (Google chrome and Safari).
Solution I am looking for
Either, point out what is wrong in my code.
Or share any properly implemented working demo of both ways scroll (horizontal + vertical) using the same version of iscroll, so that I can follow the same. I am using - version 3.7.1, preferable, or using iscroll version 4, fine as well.
Or any pointers, of course, would be appreciated.
Problem Description
Please check working code here - http://jsfiddle.net/sandeepan_nits/pAhjU/6/
Note -
Test in webkit browsers only (Google chrome and Safari).
I have knowingly put everything inside the HTML section in the jsfiddle, because if I separate things completely, the scrolling does not work, and I am not sure where exactly it stops working. Thanks if you can point out.
Code
Here is the HTML -
<div class="header">
<div class='left_link'></div>Demo</div>
<div id="main_content" class="main_content">
<b><div id=scroller1><br/>
<div class='center_data'>Scrollable area</div>
<div class='center_data'>hello world!</div>
<br/>
</div></b>
</div>
Note - I know there is invalid html there - <div id=scroller1> is inside <b></b> and I am not sure why if I remove the <b></b> tags, horizontal scrolling does not work anymore - check here.
Here is the js -
var myScroll;
var a = 0;
function loaded() {
//setHeight(); // Set the wrapper height. Not strictly needed, see setHeight() function below.
// Please note that the following is the only line needed by iScroll to work. Everything else here is to make this demo fancier.
myScroll = new iScroll('scroller1', {desktopCompatibility:true});
//myScroll2 = new iScroll('scroller2', {desktopCompatibility:true});
}
// Prevent the whole screen to scroll when dragging elements outside of the scroller (ie:header/footer).
// If you want to use iScroll in a portion of the screen and still be able to use the native scrolling, do *not* preventDefault on touchmove.
document.addEventListener('touchmove', function (e) { e.preventDefault(); }, false);
// Load iScroll when DOM content is ready.
document.addEventListener('DOMContentLoaded', loaded, false);
I guess the reason is that the scrollable div is by default rendered at the bottom-right corner of the scrollable area. But I am not sure about the proper way to configure those things - how to set where to render the scrollable div inside the scollable area. So far I did not find any working demo of both ways scrolling - horizontal + vertical scrolling.
I checked out the documentation of iscroll and many working demos, but did not find any demo where scrolling can be done both ways - horizontally as well as vertically. I checked the "Accepted options are:" section under "Syntax" section in http://cubiq.org/iscroll but none of those params seem to be what I am exactly looking for.
Other things
Also, one more thing, I am not able to view the area covered by dom elements in chrome browser, while I inspect the given scroll demo. By viewing the area I mean moving the mouse over the dom inspector panel highlights the dom in the browser view. When does it not appear? I checked with validated HTML as in http://jsfiddle.net/sandeepan_nits/pAhjU/12/.
Somebody please create a tag iscroll or iscroll3 so that I can retag my question.
Update
I just want to have normal two dimensional scrolling with the scroll area being properly inside the visible screen and there should be bounce back on taking outside the screen. Right now there is no bounce back (in my jsfiddle) on scrolling towards top and left, outside screen. Bounce back happens on scrolling to right and bottom. I just want the scrolling area to be well placed inside the screen. I guess bounce back will automatically get fixed then.
I think the last version (4.1.8) on the github repo will fix your problem ;) I'm using it on some projects and it is now optimized for desktop browser ;)
Edit
From the documentation :
hScroll, used to disable the horizontal scrolling no matter what. By default you can pan both horizontally and vertically, by setting this parameter to false you may prevent horizontal scroll even if contents exceed the wrapper.
vScroll, same as above for vertical scroll.
By default, when creating a new iScroll('idOfElement') the scroll is vertical and horizontal. It can be disabled with these parameters. Dual Scroll is totally possible as this video shows it.
So, to force dual Scroll :
var myScroller = new iScroll('idOfElement', {vScroll:true, hScroll:true});
This is not a complete solution, but this might help you.
First of all, The HTML code was not properly nested, and so you were needed to put the <div> inside the <b>. I fixed up the HTML a bit and its working without the <b>
http://jsfiddle.net/Aexhz/
And with properly nested HTML and correct settings, This worked even after dividing the HTML/JS/CSS
For me, it does show some Horizontal as well as Vertical Scrolling, but i don't know if that's how you want it to be. i Edited the Class initialization line as well
myScroll = new iScroll('scroller1', {desktopCompatibility:true});
TO
myScroll = new iScroll('scroller1', {
snap: true,
momentum: false,
hScrollbar: false,
vScrollbar: false,
desktopCompatibility: true
});
This doesn't affects much but i still put that.
I will continue looking into this and update my answer if i find anything new.
I know you want to fix this using iscorll but wanted to share this with you, i had great results using it: http://jscrollpane.kelvinluck.com/#usage
It is highly customizable with css, a demo here with vertical and horizontal scroll: http://jscrollpane.kelvinluck.com/basic.html
So I have this page here:
http://www.eminentmedia.com/development/powercity/
As you can see when you mouse over the images the div slides up and down to show more information. Unfortunately I have 2 problems that i can't figure out and I've searched but haven't found quite the right answer through google and was hoping someone could point me in the direction of a tutorial.
The first problem is that when you mouse over an image it changes to color (loads a new image), but there's a short delay when the image is loading for the first time so the user sees white. Do I have to preload the images or something in order to fix that?
My second problem is that when you move your mouse over the 'additional content area' it goes crazy and starts going up and down a bunch of times. I just don't have any idea what would cause this but i hope one of you will!
All my code is directly in the source of that page if you would like to view the source.
Thanks in advance for your help!
Yes, you have to preload the images. Thankfully, this is simple:
var images_to_preload = ['myimage.jpg', 'myimage2.jpg', ...];
$.each(images_to_preload, function(i) {
$('<img/>').attr({src: images_to_preload[i]});
});
The other thing you have to understand is that when you use jQuery you have to truly embrace it or you will end up doing things the wrong way. For example, as soon as you find yourself repeating the same piece of code in different places, you are probably doing something wrong. Right now you have this all over the place:
<div id="service" onmouseover="javascript:mouseEnter(this.id);" onmouseout="javascript:mouseLeave(this.id);">
Get that out of your head. Now. Forever. Always. Inline javascript events are not proper, especially when you have a library like jQuery at your disposal. The proper way to do what you want is this:
$(function() {
$('div.box').hover(function() {
$(this).addClass('active');
$(this).find('div.slideup').slideDown('slow');
}, function() {
$(this).removeClass('active');
$(this).find('div.slideup').slideUp('slow');
});
});
(You have to give all the #industrial, #sustainable, etc elements a class of 'box' for the above to work)
These changes will also fix your sliding problem.
I can see your images (the ones that are changing) are set in the background of a div. Here is a jquery script that preloads every image found in a css file. I have had the same problem in the past and this script solves it. It is also very easy to use:
http://www.filamentgroup.com/lab/update_automatically_preload_images_from_css_with_jquery/
I will take a look at your other problem...
1) You should be using the jquery events to drive your mouseovers. Give each div a class to indicate that its a category container and use the hover function to produce the mouseover/mouseout action you're after.
html
<div id="industrial" class="category"></div>
Javascript
$(".category").hover(
function () {
$(this).find('.container').show();
},
function () {
$(this).find('.container').hide();
}
);
I simplified the code to just do show and hide, you'll need to use your additional code to slide up and slide down.
2) Yes, you need to preload your images. Another option would be "sprite" the images. This would involve combining both the black and white and colour versions of each image into a single image. You then set it as the div's background image and simply use CSS to adjust the background-position offset. Essentially, sliding instantly from the black and white to colour images as you rollover. This technique guarentees that both images are fully loaded.
