I wanted to use the new observe feature but it does not seem to be working. At least not for me.
First things first here is the result of mrt --version
Meteorite version 0.4.6
Meteor version 0.5.9 (git checkout)
The goal is to create a bunch of draggable elements whose position gets reflected among clients.
Tis is my query:
var items = Items.find({});
var handle = items.observe( {
changed: function (newDocument, oldDocument) {
if ( newDocument._id !== dragged ) {
$( "#" + id ).style( "left", newDocument.left );
$( "#" + id ).style( "top", newDocument.top );
}
}
} );
I know the positions are changed because when I reload the page the images get synchronized. I tried with both observe and observeChanged with the same result. If I set a break point inside the callback it is never called.
could it be because I still have insecure and autopublish on?
thank you for your help
it looks like it helps to remove insecure and autopublish but more importantly, to wait until the subscription is ready.
I ended up using the Meteor.subscribe("name", function() {}); syntax and it works now.
here is the full code:
Meteor.subscribe("allItems", function() {
var items = Items.find( {} );
Session.set( "items", items.fetch() );
handle = items.observe( {
changed: function ( newDocument, oldDocument ) {
if ( newDocument._id !== dragged ) {
$( "#" + newDocument._id ).css( "left", newDocument.left );
$( "#" + newDocument._id ).css( "top", newDocument.top );
}
}
} );
});
hope that helps

In a plugin, we're using a button & text input to trigger the wpLink modal. All works well, until we hit a template that removes the main content editor and relies only on metaboxes for the page content.
The error we're getting is this.textarea is undefined. The code we're using is:
$( 'body' ).on( 'click', '.pluginxyz-add-link', function( event ) {
wpActiveEditor = true;
wpLink.open();
return false;
});
So I assume there is some dependency to the main editor. I can't find explicit info/documentation around this.. anyone have a suggestion about making this work without the main editor?
Actually, I just figured this out. In our code, the ONLY sibling text input is always where the value will go.
$( 'body' ).on( 'click', '.pluginxyz-add-link', function( event ) {
clickedEle = $( this );
textBoxID = $( clickedEle ).siblings( 'input[type=text]' ).attr( 'id' );
wpActiveEditor = true;
wpLink.open( textBoxID);
return false;
});
I have a header.php, that appears in every single page on my blog, with a navbar that looks like this:
<nav>
<ul>
<li>Logistics</li>
<li>Contact</li>
</ul>
</nav>
But when I click the anchor tag linking to #contact, which is located in page with id 5, as you can see by the php code, nothing happens. I tried using a slash (/#contact) but I keep getting the same behavior. Isn't this the correct way of linking to a specific id on another page?
EDIT: I also have some smooth scrolling code (below) which I think may be related to my issue.
<script>
$( document ).ready( function () {
// Add smooth scrolling to all links
$( "a" ).on( 'click', function ( event ) {
// Make sure this.hash has a value before overriding default behavior
if ( this.hash !== "" ) {
// Prevent default anchor click behavior
event.preventDefault();
// Store hash
var hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll
// The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
$( 'html, body' ).animate( {
scrollTop: $( hash ).offset().top
}, 800, function () {
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
} );
} // End if
} );
} );
</script>
Thanks!
You have a javascript error.
<script>
$( document ).ready( function () {
// Add smooth scrolling to all links
$( "a" ).on( 'click', function ( event ) {
// Make sure this.hash has a value before overriding default behavior
if ( this.hash !== "" ) {
// Prevent default anchor click behavior
event.preventDefault();
// Store hash
var hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll
// The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
$( 'html, body' ).animate( {
scrollTop: $( hash ).offset().top
}, 800, function () {
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
} );
} // End if
} );
} );
</script>
Here is the problem. On the home page you have a div with id #contato. On the other pages it is not there.
$( 'html, body' ).animate( {
scrollTop: $( hash ).offset().top
}, 800, function () {
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
} );
Your hash var's value is "#contato", but when js tries to get it's offset you recieve an error saying that it's impossible to read property top of 'undefined'. So, you can try to remove that part of the script from the other pages and only keep it on home. This should work like a charm. If you have any question, please ask.
LE: I'd recommend this method for smooth scroll (I didn't tested it for your case, but it always worked for me)
$(function() {
$('a[href*="#"]:not([href="#"])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if (target.length) {
$('html, body').animate({
scrollTop: target.offset().top
}, 1000);
return false;
}
}
});
});
use
<?php echo get_page_link(5)."#contact"; ?>
instead of get permalink function
Here is my full first working test:
var expect = require('chai').expect;
var assert = require('assert');
var webdriverjs = require('webdriverjs');
var client = {};
var webdriverOptions = {
desiredCapabilities: {
browserName: 'phantomjs'
},
logLevel: 'verbose'
};
describe('Test mysite', function(){
before(function() {
client = webdriverjs.remote( webdriverOptions );
client.init();
});
var selector = "#mybodybody";
it('should see the correct title', function(done) {
client.url('http://localhost/mysite/')
.getTitle( function(err, title){
expect(err).to.be.null;
assert.strictEqual(title, 'My title page' );
})
.waitFor( selector, 2000, function(){
client.saveScreenshot( "./ExtractScreen.png" );
})
.waitFor( selector, 7000, function(){ })
.call(done);
});
after(function(done) {
client.end(done);
});
});
Ok, it does not do much, but after working many hours to get the environement correctly setup, it passed. Now, the only way I got it working is by playing with the waitFor() method and adjust the delays. It works, but I still do not understand how to surely wait for a png file to be saved on disk. As I will deal with tests orders, I will eventually get hung up from the test script before securely save the file.
Now, How can I improve this screen save sequence and avoid loosing my screenshot ?
Since you are using chaning feature of webdriverjs it is wrong to use callback in waitFor function.
Function saveScreenshot is also chained. So the proper way would be the following:
it('should see the correct title', function(done) {
client.url('http://localhost/mysite/')
.getTitle( function(err, title){
expect(err).to.be.null;
assert.strictEqual(title, 'My title page' );
})
.waitFor( selector, 2000)
.saveScreenshot( "./ExtractScreen.png" )
.call(done);
});
I'm using the Vitrux theme in Wordpress that uses Isotope jQuery plugin to display a work porfolio. Isotope allows categories to be used to sort the items, but within the theme it's only possible to sort by one category at a time (e.g. 'Year' or 'Type', not 'Year' and 'Type'.
You can see a mock-up here: http://snaprockandpop.samcampsall.co.uk/shoots/
The jQuery attached to each category item, that sorts the posts, is as follows:
function (){
var selector = $(this).attr('data-filter');
$container_isotope.isotope({ filter: selector });
var $parent = $(this).parents(".filter_list");
$parent.find(".active").removeClass('active');
$(".filter_list").not($parent).find("li").removeClass('active').first().addClass("active");
$(this).parent().addClass("active");
return false;
}
I can see from the Isotope site that it's possible to use multiple filters, and I've found the authors notes on this here: http://jsfiddle.net/desandro/pJ6W8/31/
EDIT:
Editing the theme files has allowed me to assign appropriate classes and properties to the filter lists (you can see these in the page source) and I'm targeting them through an edited version of the jsfiddle to reflect the classes and id's in the theme styling:
$( function() {
var $container = $('#portfolio_container');
$container.isotope({
animationOptions: { duration: 300, easing: 'linear', queue: false },
getSortData : {
year : function ( $elem ) { return parseFloat( $elem.find('._year').text() ); },
live-shows : function ( $elem ) { return parseFloat( $elem.find('._live-shows').text() ); }
}
});
var filters = {};
$('.ql_filter a').click(function(){
var $this = $(this);
if ( $this.hasClass('selected') ) {
return;
}
var $optionSet = $this.parents('.filter_list');
$optionSet.find('.active').removeClass('active');
$this.addClass('active');
var group = $optionSet.attr('data-filter-group');
filters[ group ] = $this.attr('data-filter');
var isoFilters = [];
for ( var prop in filters ) {
isoFilters.push( filters[ prop ] )
}
var selector = isoFilters.join('');
$container.isotope({ filter: selector });
return false;
});
});
Two (fairly major) things:
1) I'm not 100% that I've edited this correctly. Despite Rich's excellent comments I'm still out of my depth. I'm particularly not clear on how to set-up the 'getSortData' section - I think it's right but any input would be great.
2) I'm not sure that this JavaScript is being initiated. At the moment I've placed it immediately before the closing head tag but a check on the page suggests that the original script outlined above is the one running on the filter items.
Any pointers at this stage would be fantastic!
I see what you mean. You are looking for the intersection of both filters and not the mutually exclusive filter values.
Short answer: Contact the theme vendor and see if they can make the intersection filters for you.
Longer assistance (not an answer):
Your ultimate goal is to get the Vitrux theme working the way you want.
Your first goal is to understand what the jsfiddle code is doing.
I can handle your first goal by explicating the code.
// hook into the JQuery Document Load event and run an anonymous function
$( function() {
// Create a variable called container
// make container refer to the element with ID Container
var $container = $('#container');
// initialize isotope
// Call the isotope method on the container element
$container.isotope({
// options...
//distracting options
animationOptions: { duration: 300, easing: 'linear', queue: false },
getSortData : {
price : function ( $elem ) { return parseFloat( $elem.find('.price').text() ); },
size : function ( $elem ) { return parseFloat( $elem.find('.size').text() ); }
}
});
// sorting button
//for the anchor tag that has a class of 'pricelow', wire up an anonymous function to the click event
$('a.pricelow').click(function(){
//Rerun the isotope method when it is clicked, pass an array of options as a parameter
$('#container').isotope({ sortBy : 'price',sortAscending : true });
//return false for the anonymous function. Not 100% sure why this is necessary but it has bitten me before
return false;
});
//removed the rest of the click methods, because it does the same thing with different params
//Here is what you are interested in understanding
//Create an empty filters object
var filters = {};
// filter buttons
//When an anchor tag with class filters is clicked, run our anonymous function
$('.filters a').click(function(){
//Create a variable that is the action anchor element
var $this = $(this);
// don't proceed if already selected by checking if a class of "selected" has already been applied to the anchor
if ( $this.hasClass('selected') ) {
return;
}
//Create an optionSet Variable, point it to the anchor's parent's class of "option-set"
var $optionSet = $this.parents('.option-set');
// change selected class
//Inside the optionSet, find elements that match the "selected" class and then remove the "selected class"
$optionSet.find('.selected').removeClass('selected');
// set this (the anchor element) class to "selected"
$this.addClass('selected');
// store filter value in object
// create a variable called 'group' that points to the optionsSet variable and grab the data-filter-group expando attribute
var group = $optionSet.attr('data-filter-group');
//Append to the filters object at the top of this section and set the data-filter-group value to the anchor tag's data-filter value
filters[ group ] = $this.attr('data-filter');
//create an isoFilters array variable
var isoFilters = [];
//Loop through each one of the items in filters (give the item an alias variable called 'prop'
for ( var prop in filters ) {
//push the prop into the isoFilters array (the opposite is pop)
isoFilters.push( filters[ prop ] )
//keep looping until there are no more items in the object
}
//create a variable called selector and turn the array into a string by joining all of the arrays together
var selector = isoFilters.join('');
//Like always, call the 'isotope' method of the 'container' element and pass our newly concatenated 'selector' string as the 'filter' option.
$container.isotope({ filter: selector });
//return false for some reason (maybe someone can expand on that)
return false;
});
});
Next is your ultimate goal which is modifying the Vitrux theme to handle intersection filters.
This gets a little tricky because
You have automatically generated tags from PHP to create the category links and the Year filter. So, there will be definitely some PHP code changes.
You must convert the jsfiddle code to handle your PHP changes
Try it using jQuery noconflict. In effect, replace any "$" with "jQuery" and see if it works.
Wordpress doesn't play well with the dollar sign.
The following lines of code document what I'm trying to acchieve. In detail, I'm trying to attach an addListener to a DOM object. Sadly it seems that I can't access it.
var dom_obj = document.getElementById( 'dom_obj_id' );
console.log( typeof dom_obj ); // console: object
google.maps.event.addListener( dom_obj, 'click', function() {
// the following two lines don't appear
alert( 'Test - called from addListener' );
console.log( dom_obj );
} );
jQuery( zoom_in ).click(
function() {
// works
alert( 'Test - called via jQuery click function' );
console.log( dom_obj );
return false;
}
);
Searched for hours and found the solution seconds after typing the Q...
Simple as it is: Use addDomListener instead.
