One thing I don't understand is how did Minima.pl (http://minima.pl/pl) implement that feature within Isotope library where clicking on a thumbnail opens up a bigger gallery of images (a single clickable image, clicking on it makes it cycle through the rest of the images in a gallery) while resorting the Isotope items?
Here is how far I got -> http://tinyurl.com/cr5kzml
Anyone have any ideas on what I'm missing, how do I get this working?
Well, I am author of minima.pl website ;).
The part which takes care of repositioning of tiles after enlarging clicked one:
$('#mainContent').isotope('reLayout', function(){
$('html, body').animate({scrollTop: item.offset().top - 10}, 400);
});
It also takes care of scrolling browser window to top of clicked tile.
I am triggering the above action after loading clicked tile content (by AJAX). The trick is to trigger it simultaneously with enlarging the clicked tile.
I will be glad to answer any additional questions.
Actually, this is simple to achieve. Normally, a click on an Isotope .item can, for example, maximise it, another click minimises it. If you want interactivity inside a clicked-on Isotope .item, you simply don't attach the minimisation function to it. Instead, clicking on another Isotope .item minimises the previously selected = maximised item. By keeping track of the previously selected .item, clicks inside the maximised .item won't close it. Basic logic for an example that allows maximising and minimising only by clicking on a "header" zone inside each Isotope .item:
$(document).ready(function () {
var $container = $('#container');
$container.isotope({
itemSelector: '.item',
masonry: {
columnWidth: 128 // corresponding to .item divs width relationships
}
});
// $container.isotope('shuffle'); // randomise for every new visitor
$items = $('.item'); // to reference methods on all .item divs later
$('.header').click(function () { // instead of registering the entire .item div (default use), only its .header div (child div) receives clicks
var $previousSelected = $('.selected'); // necessary for switching
if ($(this).parent().hasClass('selected')) { // use $(this).parent() (not $(this)), because the .header div is a child of the .item div
$(this).parent().removeClass('selected');
$(this).parent().children('.maximised').hide();
$(this).parent().children('.minimised').show();
$items.find('.minimised, .header').removeClass('overlay'); // returns all .minimised divs to previous state after the .item is closed again
} else {
$previousSelected.removeClass('selected');
$previousSelected.children('.minimised').show();
$previousSelected.children('.maximised').hide();
$(this).parent().addClass('selected');
$(this).parent().children('.minimised').hide();
$(this).parent().children('.maximised').show();
$items.not('.selected').find('.minimised, .header').addClass('overlay'); // adds .overlay on each .item which is not currently .selected
}
$container.isotope('reLayout'); // comment out to mimick old masonry behaviour
});
});
The actual interactivity inside each Isotope .item can then be coded however you like; hardcoded or dynamic...
By click on a thumbnail a ajax function return the same gallery except a bigger replacement for the thumbnail. Then let isotope rearrange the gallery. You can find an example here: http://www.maxmedia.com or http://www.phpdevpad.de (my own site).

I am having a little trouble figuring out how to turn on the grid visualization: https://github.com/Team-Sass/Singularity/wiki/Creating-Grids#visualizing-your-grids.
Can someone point me to more help or share an example?
This can be found deep within the singularitygs Ruby gem:
Grid Overlay & Background
There are three ways you can display a grid:
Manually apply the background to the element
.container {
#include background-grid;
}
Add a switch to toggle an overlay -
#include grid-overlay('.container');
Toggle grid with JavaScript
#include grid-toggle in an SCSS * { … } or html { … } element.
Add [data-development-grid="show"] to item you want grid applied to
Add "grid.js" to the HTML head
The first will apply a grid background to your container calculated using your
grid settings, media breakpoints etc.
The second will add a switch to your page which allows you to view a grid
overlay over your container (or if none is provided) by hovering over
the switch. if you need your mouse for other things you can toggle the overlay
on permanently by inspecting and checking :hover in your styles panel.
The third will allow you to toggle your background grid on and off by pressing the 'g' on your keyboard.
I couldn't get grid.js to work, so I rewrote it using a bit of jQuery. Here is my version:
// A working jQuery/javascript script for the hide/show grid
$(document).ready(function() {
$('html').keypress(function(event) {
if (event.which === 103) {
var wrap = document.getElementById("wrap");
var dev = wrap.getAttribute('data-development-grid');
if (dev === null || dev === 'hide') {
wrap.setAttribute('data-development-grid', 'show');
}
else {
wrap.setAttribute('data-development-grid', 'hide');
}
}
});
});
I find method 2 is rather neat. You get a symbol of 4 vertical bars in the bottom left of your webpage and the grid appears with mouseover. Similar to Susy's Home Page
Currently I have a page which on load scatters draggable divs randomly over a page using math.random
Using media queries however the page uses packery to display the same images for browser widths under 769px in a grided fashion.
I had the idea that it could be interesting to create a 'sort/organize' button which would rearrange these divs using packery and remove the draggable class already applied, however i have no idea if this is possible or how to go about it. If there is any method of animating this process that would also be a bonus!
If anyone could at the very least point me in the right direction i would be extremely thankful!!
Hopefully this gives you a bit of a starting point.
I would read up on JQuery as it has some useful helpers for DOM manipulation.
I don't think this is the most efficient way to do it, and I think you will need to rethink your test harness for doing this in the future, but hopefully this gets you started.
Firstly I've added a button to trigger the sort
<div class="rotate" id="contact">Contact</div>
<div id="logo">Andrew Ireland</div>
<button id="sort">sort</button>
Then updated the script to override the css setting to switch between draggable view and item view.
// general wait for jquery syntax
$(function(){
// trigger the layour to sort get the packery container
var container = document.querySelector('#container.packery');
var pckry = new Packery( container );
//button function
$("#sort").click(function(){
//Hide all the dragged divs
//ui-helper-hidden is a jquery ui hider class
if($('.box').css('display') == 'block') {
$('.box').css({'display':'none'});
//Show all the item class's
$('.item').css({'display':'block'});
//show the container
$('#container').css({'display':'block'});
// trigger the layour to sort
pckry.layout();
} else {
//hide all the item class's
$('.item').css({'display':'none'});
//hide the container
$('#container').css({'display':'none'});
//show the draggable box's
$('.box').css({'display':'block'});
}
});
$( ".pstn" ).draggable({ scroll: false });
$(".pstn").each(function(i,el){
var tLeft = Math.floor(Math.random()*1000),
tTop = Math.floor(Math.random()*1000);
$(el).css({position:'absolute', left: tLeft, top: tTop});
});
});
As I said this is more to get started. The packery documentation details how to trigger its layout functions so another approach would be to only have the draggable elements, and put these inside a packery container. Then when you want to sort them you can just trigger that the packery.layout() function.
I hope this is helpful, I am only just getting started on stack overflow so any feedback would be appreciated.
As the title says. I want to make a list of div elements inside a div. I want to be able to scroll the list up and down, and when the list is not scrolling anymore, i want to be able to click the listed elements do to something. I cant figure out how to do this.
the touchmove event executes whenever the user touches the div, even if the div its scrolling. THen i cant figure out how to make let the program know that the div isnt scrolling anymore, so the next touch on the elements will trigger a non scrollable event.....
EDIT:
what i have so far is this... However this is a quick "fix" and its not working as intended. For example if you scroll quickly up and down, then the div will think you pressed on one of the elements..
exerciseWrapper is the elements inside the scrolling div. Each element is wrapped around exerciseWrapper.
$('.exerciseWrapper').on('touchstart',function(){
touchstart=true;
setTimeout(function(){
touchstart=false;
}, 100);
});
$('.exerciseWrapper').on('touchend',function(){
if(touchstart)
{
$('.exerciseWrapper').not(this).css('border-color','black');
$(this).css('border-color','orange');
}
});
Ok so i finally figured this one out.. Reason why i couldnt wrap my minds around the solution on this, was because i couldnt get other events then eventstart and event end to work... At the time of writing i still cant get the other events like eventcancel and eventleave to work. However eventmove works and i solved the problem using this event. eventmove keeps updating the element its linked when you move your finger. Then i had a variable of touchmove to constantly be true if i am scrolling my div (with touchmove event). WHen i stop moving i can clik on selected element again and use a normal eventstart event.. This is my working code:
var touchmove=false;
function AddExercisesEvents()
{
$('#exerciseMenu').on('touchmove',function(){
touchstart=true;
$('h1').text("move");
});
$('.exerciseWrapper').on('touchend mouseup',function(event){
event.stopPropagation();
event.preventDefault();
// $('.exerciseWrapper').off();
if(event.handled !== true)
{
touchstart=false;
//ENTERING editExercise Menu..!
if(!touchstart)
{
//insert magic here
alert($(this).attr('id'));
}
}
return false;
});
}
I want to reduce them to a maximum 200px width and keep the same layout with the 10px spacing the photos have. Also I don't want to style the posts to be that wide and use overflow:hidden that will only cut off the photosets.
jQuery Solution
For this solution you will need the latest version of jQuery and the jQuery plugin imagesLoaded included in the head of the theme before the following:
<script type="text/javascript">
$(document).ready(function() {
$('iframe.photoset').each(function() {
var i = this;
$(i).attr("onload", "ps_resize(this)");
var s = $(i).attr("src");
s = s.replace(/\/500\//, "/200/");
$(i).attr("src", s);
});
});
function ps_resize(i) {
$(i).contents().find("body").imagesLoaded(function() {
$(i).attr("width", 200);
$(i).attr("height", $(this).height());
});
return false;
}
</script>
What Solution Does
When the DOM is ready, find all the photoset iFrames
For each iFrame...
set the "onload" attribute to your frame resizing function
get the frame's source url, change the size (e.g. 500) to 200
set the frame's source url (this will cause it to reload with a smaller photoset)
In the resizing function...
wait for the images to load
set the frame width to 200
set the frame height to the new height of the photoset
Additional Code for Infinite Scroll
If you are using the Infinite Scroll jQuery Plugin, you will need to additionally include this in your success callback function:
...
$(newElements).find('iframe.photoset').each(function() {
var i = this;
$(i).attr("onload", "ps_resize(this)");
var s = $(i).attr("src");
s = s.replace(/\/500\//, "/200/");
$(i).attr("src", s);
});
...
Obviously, if you're using Infinite Scroll, I would suggest defining a function that is called on each iFrame on both the initial load and the scroll so you don't have repeated code to maintain.
I'm currently using jQuery Waypoints to highlight nav items as you scroll through sections of the page. All of that works fine; thanks to copying the code from the demo at http://imakewebthings.github.com/jquery-waypoints/.
My demo is: http://www.pandlmedia.com/index.php/index_new
However, I also want to create a waypoint at the #footer div which would trigger an event to change the color of all of the nav links.
$('#footer').bind('waypoint.reached', function(event, direction) {
$('.nav ul a').addClass('white');
});
This doesn't work, as there's nothing telling it to change back once it exits the #footer div. I'm not very experienced in writing jQuery or using this plug-in for that matter. What do I need to add to make this work? Is the fact that there are two levels of waypoints also causing problems?
well, looking closer at the "sticky elements" demo, I was able to modify the example of the disappearing '.top' button to make this work for my own needs described above:
<script type="text/javascript">
$(document).ready(function() {
$('.container .nav ul a').addClass('black');
$.waypoints.settings.scrollThrottle = 30;
$('#footer').waypoint(function(event, direction) {
$('.container .nav ul a').toggleClass('black', direction === "up");
}, {
offset: '50%'
});
});
The key was to add the .black class below the .white class in my css so that it overrides the color parameter properly.
