I've implemented Isotope this way http://jsfiddle.net/circlecube/LNRzZ/ to my Joomla website. Sorting and filtering work perfeclty but only in the current page.
I would like to sort/filter all items but display only 20 items per page. I wish to keep a numeric navigation, like this http://tutorials.vinnysingh.co/quicksand/.
Can Isotope handle this or should I use another plugin? Any help is greatly appreciated. Thanks in advance.
Here is my full code:
jQuery( document ).ready( function ($) {
// cache container
var $container = $('#container');
// initialize isotope
$container.isotope({
getSortData : {
author : function ( $elem ) {
return $elem.find('.author').text();
},
city : function ( $elem ) {
return $elem.find('.city').text();
},
country : function ( $elem ) {
return $elem.find('.country').text();
},
price : function( $elem ) {
return parseFloat( $elem.find('.price').text().replace( /[\(\)]/g, '') );
},
rating : function ( $elem ) {
return parseInt( $elem.find('.rating').text(), 10 );
},
review : function ( $elem ) {
return parseInt( $elem.find('.review').text(), 10 );
},
perfDate: function (element) {
// parse out the performance date from the css classes
var classList = element.attr('class').split(/\s+/);
var dateClassPrefix = 'date-';
var date;
$.each(classList, function(index, cssClassName){
if (cssClassName.substring(0, dateClassPrefix.length) === dateClassPrefix) {
// Should be a date in format 'yyyy-MM-dd'
var dateString = cssClassName.substring(dateClassPrefix.length);
date = SF.parseDate('dd/mm/yyyy').getTime();
}
});
return date;
}
}
});
$('#sort-by a').click(function(){
// get href attribute, minus the '#'
var sortName = $(this).attr('href').slice(1);
$('#container').isotope({ sortBy : sortName });
return false;
});
// filter items when filter link is clicked
$('#filters a').click(function(){
var selector = $(this).attr('data-filter');
$container.isotope({ filter: selector });
return false;
});
var $optionSets = $('#options .option-set'),
$optionLinks = $optionSets.find('a');
$optionLinks.click(function(){
var $this = $(this);
// don't proceed if already selected
if ( $this.hasClass('selected') ) {
if ($this.hasClass('lock')){
//return false;
}
else if ($this.hasClass('asc')){
$this.removeClass('asc').addClass('desc');
}
else if ($this.hasClass('desc')){
$this.removeClass('desc').addClass('asc');
}
}
var $optionSet = $this.parents('.option-set');
$optionSet.find('.selected').removeClass('selected');
$this.addClass('selected');
// make option object dynamically, i.e. { filter: '.my-filter-class' }
var options = {},
key = $optionSet.attr('data-option-key'),
value = $this.attr('data-option-value');
// parse 'false' as false boolean
value = value === 'false' ? false : value;
options[ key ] = value;
if ($this.hasClass('asc') || $this.hasClass('desc'))
options[ 'sortAscending' ] = $this.hasClass('asc');
if ( key === 'layoutMode' && typeof changeLayoutMode === 'function' ) {
// changes in layout modes need extra logic
changeLayoutMode( $this, options )
} else {
// otherwise, apply new options
$container.isotope( options );
}
return false;
});
});
Isotope doesn't do pagination. You'll need to implement the pagination in Joomla.

I'm appending isotope items via Ajax in Wordpress:
My JS Code:
var $news_container = $('#news'); //The ID for the list with all the blog posts
$news_container.isotope({ //Isotope options, 'item' matches the class in the PHP
itemSelector: '.newsItem',
masonry: {
columnWidth: '.news-item-sizer',
gutter: '.gutter-sizer'
}
});
var has_run = false;
var init_offset = 0;
$('button.showall').click(function(e) {
e.preventDefault();
var button = $(this);
// Disable button
$(button).removeClass('showall');
$(button).addClass('showless');
// Record Nonce
var nonce = $(this).data("nonce");
if(has_run == false) {
button.data('offset', $(this).data("offset"));
init_offset = $(this).data("offset");
}
// Set AJAX parameters
data = {
action: 'mft_load_more_ajax',
init_offset: init_offset,
offset: button.data('offset'),
nonce: nonce
};
$.post(mft_load_more_ajax.ajaxurl, data, function(response) {
// Set Container Name
var response = JSON.parse(response);
console.log(response);
// Run through JSON
$.each( response, function( key, value ) {
// Set Value
var val = $(value);
// Set Container
var $container = $('#news').isotope();
// Append Val
$container.append(val).isotope( 'appended', val );
$(button).html('show less');
});
// Set Offset
var offset = button.data("offset");
button.data("offset", offset + 11 );
// If Has Run
has_run = true;
return false;
}
Until now, this works quite fine. Now I would like to switch the buttontext and it's class to .showless and on the next click all previously appended items should be removed. They all have the class .newsItem.appendedItem.
I tried this method:
$('button.showless').click(function(e) {
var button = $(this);
console.log('showless');
$out = $('.newsItem.appendedItem');
var isotopeInstance = $('#news').data('isotope');
isotopeInstance.$allAtoms = isotopeInstance.$allAtoms.not($out);
$out.remove();
// Disable button
$(button).removeClass('showless');
$(button).addClass('showall');
has_run = false;
return false;
});
Unfortunately this doesn't work, because the showless function is not even being entered, as I don't get a log in the console. What am I overlooking?
Thanks for your help!

Update 1:
I'm getting this error in Google Console.
Not sure, what was the problem now. But I cleaned the code a little bit with using an if statement, to check if the elements already got appended.
So my final code now looks like this:
var $news_container = $('#news'); //The ID for the list with all the blog posts
$news_container.isotope({ //Isotope options, 'item' matches the class in the PHP
itemSelector: '.newsItem',
masonry: {
columnWidth: '.news-item-sizer',
gutter: '.gutter-sizer'
}
});
var is_appended = false;
$('button.showall').click(function(e) {
e.preventDefault();
var button = $(this);
// Record Nonce
var nonce = $(this).data("nonce");
if(is_appended == false) {
button.data('offset', $(this).data("offset"));
// Disable button
button.prop( "disabled" , true );
// Set AJAX parameters
data = {
action: 'mft_load_more_ajax',
offset: button.data('offset'),
nonce: nonce
};
$.post(mft_load_more_ajax.ajaxurl, data, function(response) {
// Set Container Name
var response = JSON.parse(response);
console.log(response);
// Run through JSON
$.each( response, function( key, value ) {
// Set Value
var val = $(value);
// Set Container
var $container = $('#news').isotope();
// Append Val
$container.append(val).isotope( 'appended', val );
});
// Undo Button Disable
button.prop( "disabled" , false );
button.html('Weniger News anzeigen');
// Set Offset
// var offset = button.data("offset");
// button.data("offset", offset + 11 );
// If Was appended
is_appended = true;
return false;
});
} else if(is_appended == true) {
$out = $('.newsItem.appendedItem');
$news_container.isotope( 'remove', $out )
// layout remaining item elements
.isotope('layout');
button.html('Alle News anzeigen');
is_appended = false;
return false;
}
});
In Chrome everything works perfectly. But just figured out, that in Firefox my Ajax array is completely empty and I'm not able to fetch any data. Probably another problem, I'm going to post separately.
I'm working on cascading the multi-select based on the values of the data-attributes on another.
I have this method which is called inside the onChanged event of the parent. By parent I mean what to filter the child by i.e
Parent = Department Multiselect
Child = Staff Multiselect.
The child element has a data attribute of data-departmentid.
function cascadeMultiselect(control, targetControl, key) {
this.control = control;
this.targetControl = targetControl;
this.key = key;
this.toHide = [];
this.toShow =[];
//Get controls selectedIds
this.selectedIds = function() {
var selected = [];
_.each($(this.control + " option:selected"), function(c) {
selected.push($(c).val());
});
return selected;
};
//Now filter
this.filter = function() {
//Get target control attribute values
_.each($(targetControl + " option"), function(tc) {
//Use the val as an identifier
var val = $(tc).val();
var data = $(tc).attr("data-" + key);
data = data.split(",");
var isMatch = anyMatchInArray(data, this.selectedIds());
if(!isMatch){
$(tc).hide();
}
});
}
this.filter();
$(targetControl).multiselect('rebuild');
}
It's being called like so:
onChange: function() {
cascadeMultiselect('#departmentlist', '#stafflist', "DepartmentID");
}
The problem is I can't hide the elements. The filter works just fine, I've tried:
$(tc).hide(); // tc = targetControl option
I've also tried to refresh instead of rebuild.
Since it seems the only way to do this was to store the values of the multiselect, and then remove / add the relevant values.
I decided to use a rudimentary Cache class:
var Cache = (function () {
this.all = [];
function Cache(control) {
this.control = control;
}
Cache.prototype.getAll = function () {
return this.all;
};
Cache.prototype.setAll = function (all) {
this.all = all;
};
return Cache;
})();
Function now looks like:
function cascadeMultiselect(control, targetControl, key, cache) {
this.control = control;
this.targetControl = targetControl;
this.key = key;
this.toHide = [];
this.toShow =[];
//To reset the multiselect
this.reset = function(){
$(targetControl).html('');
$(targetControl).multiselect('dataprovider', cache.all)
}
//Get controls selectedIds
this.selectedIds = function() {
var selected = [];
_.each($(this.control + " option:selected"), function(c) {
selected.push($(c).val());
});
return selected;
};
//Now filter
this.filter = function() {
//Get target control attribute values
_.each($(targetControl + " option"), function(tc) {
//Use the val as an identifier
var val = $(tc).val();
var data = $(tc).attr("data-" + key);
data = data.split(",");
var isMatch = anyMatchInArray(data, this.selectedIds());
console.log($(tc));
if(!isMatch){
$(tc).remove();
}
});
}
//If nothing selected then reset the multiselect
if(this.selectedIds().length == 0){
this.reset();
return;
}else{
this.filter();
}
$(targetControl).multiselect('rebuild');
}
When I first populate the multiselect with the dataprovider I add the data to the cache:
if(cache != null){
cache.setAll(this.dataToAdd);
}
How to filter or sort info without data-attribute by plugin of MixItUp/Isototpe?
Maybe filter will be an #url and sort will be class.
Assuming you have a JSON set, you can filter against the values like so (I'm also assuming you have taken the filter/sort value from the DOM already):
Haven't run this so apologies if not exact - and I'm not used to stack overflow formatting yet but any issues and I'll edit. I think the logic should be OK
var dataset = [
{url: '/test'},
{url: '/test2'}
];
var filterValue = '/test2'; // pass this to function or get from DOM
var sortBy = 'url'; // again, pass in somewhere or get from DOM
var sortType = 'asc';
function filter(data, filter) {
var filteredResults = data.filter(function (el) {
return (filter !== '' && el.url.toLowerCase().indexOf(filter.toLowerCase())) !== -1;
})
return filteredResults;
}
function sort(data, sortBy, sortType) {
var sortIndex = sortType === "asc" ? 1 : -1;
data.sort(function (a, b) {
if (a[sortBy] < b[sortBy]) {
return -1 * sortIndex;
} else if (a[sortBy] > b[sortBy]) {
return 1 * sortIndex;
}
return 0;
})
}
var filteredResults = filter(dataset, filterValue);
sort(dataset, sortBy, sortType); //dataset will be sorted
I have a problem with my script. I want to remove the load more button and instead do an infinite scroll when I get to bottom of the page.
I'm using a WordPress template and without support I'm stuck on this nonsense.
What should I change to do to this script?

// or use the size of the first item
this.$filteredAtoms.outerWidth(true) ||

containerWidth;

I think this script is taken from "HEAT WORDPRESS THEME" directly which is located in js folder of the theme. Its simple to modify,you just need to remove Ajax post loading function and keep Isotop initializing function only. For help see this link

I need your help again :)
I'm trying to do a plugin with jQuery specifications.
So I started reading this: http://docs.jquery.com/Plugins/Authoring
The document is cool and give nice patterns to follow.
But i have a problem with my plugin.
My plugin appends a div and bind some events to diferents features.
Sometimes i need to accés to the options var but... the problem is, if i do the opt var global it take the last object created options.
And if i put it in the init method, i can't use it in other actions.
I need each new object can acces only his own option set.
(function( $ ) {
//plugin methods
var methods = {
init : function( options ) {
//default options
var opt = $.extend({
'id' : 'test',
'title' : 'Test window',
'type' : 'normal',
'text' : 'test test! <br/> 123',
'shines' : '',
'head_shines' : '',
'body_shines' : '',
'bottom_bar' : true
}, options);
//shine or not shine? that's the matter
if (opt.shines != '') {
opt.shines = "shiny";
opt.head_shines = " shine_head";
opt.body_shines = " shine_body";
}
//maintaining Chainability
return this.each(function() {
var $this = $(this); // $this is now JQuery object
//creating the bottom bar
if (opt.bottom_bar == true && $("#bottom_bar").length == 0) {
$this.append('<div id="bottom_bar"></div>');
}
//creating the new window
$this.append("<div style='display: none;' class='window "+opt.shines+"' id='"+opt.id+"'>...boring html...</div>");
//append new window to the bar
$("#bottom_bar").append("<div style='display: none' class='section' id='s_"+opt.id+"'>"+opt.title+"</div>");
//get a object of the window to interact with
var $window = $("#"+opt.id);
//show the windows
$window.fadeIn().draggable();
$("#s_"+opt.id).fadeIn();
//attach the events to the windows
$window.find('.close').one('click.ventana', methods.close);
$window.find('.max').on('click.ventana', methods.maximize);
$window.find('.min').on('click.ventana', methods.minimize);
$("#s_"+opt.id).on('click.ventana', methods.minimizeBar);
});
},
close : function() {},
maximize : function() {}, //i want acces my opts here!
minimize : function() {},
minimizeBar: function() {} //or here... etc
}; //end methods
//creating the plugin
$.fn.ventana = function( method ) {
if ( methods[method] ) { //if we call a method...
return methods[ method ].apply( this, Array.prototype.slice.call( arguments, 1 ) );
} else if ( typeof method == 'object' || !method ) { //if not, we use init
return methods.init.apply( this, arguments);
} else { //method don't exists (console error)
$.error( 'Method ' + method + ' does not exists in jQuery.ventana');
}
};
}) ( jQuery );
The problem is, if i put where is the first comment:
//plugin methods
this:
//globals define
var opt;
I only get the last object opts...
Example creating new windows
$('body').ventana( {
'id' : 'master',
'title' : 'Afegir Finestres',
'text' : 'test'
});
$('body').ventana( {
'id' : 'master1',
'title' : 'Afegir Finestres1',
});
I just gonna get the master1 opts in both objects
You could use data to store the options object to be retrieved later.
// store it
$this.data("options", opt);
// ...
// use it later
var opt = $this.data("options");
