I guess the answer is expand - but the expand-event does not seem to fire.
But let me start at the beginning: I have a nice tree and I'd like to use jBox to display information about certain nodes. I noticed that this worked only for nodes that were visible when the tree was created, but it did not work for nodes under collapsed nodes. So I thought I could use expandand assign an event-handler that would call jBoxto create the tooltips. But it did not work. I added a console.log to the `expand-handler and noticed that it never logged.
Am I specifying it incorrectly?
Fiddle here. The "SD"-Node has some items in it which should have a tooltip attached to the (i)-icon.
It doesn't fire because you are passing in a string:
"expand": "function(event, data) {...}"
You need to remove the double quotes, so that it is a function:
"expand": function(event, data) {...}
See updated fiddle: http://jsfiddle.net/pgh52m4w/3/
The same counts for the event "dblclick". Remove the double quotes there too.
Also, it is encouraged to use the .attach() method when attaching jBox. The attach method will check if this jBox was already attached to the element and only attaches it if it wasn't.
See the updated fiddle. I created a variable for the tooltip and reattach it in the expand event:
$(function() {
var treei = $("#tree").fancytree({
expand: function () {
myTooltip && myTooltip.attach(); // Reattaching Tooltip
}
// ...
});
var myTooltip = new jBox("Tooltip", { // get tooltips showing
attach: '[data-jbox-content]',
getTitle: "data-jbox-title",
getContent: "data-jbox-content"
});
});

I have a set of markers that have binded popups, but I can't figure out how to show all the popups when the marker group is toggled in the layers control.
For example, I have my markers like so:
var testMarker = L.marker([32.9076,33.35449]).bindPopup('Marker 1');
var testMarkerTwo = L.marker([33.58259,34.64539]).bindPopup('Marker 2');
Then, I put it in a freature group and append the openPopup method:
var markerGroup = L.featureGroup([testMarker,testMarkerTwo]).openPopup().addTo(map);
This doesn't work.
My final goal is to add that featureGroup to my layers control where I can toggle the group off/on. Before I get to that part, I need to first understand why the openPopup method is not working.
Edit: The answer below appears to only work with the plain Leaflet API, not the Mapbox API.
There are a couple problems here. The first is that by default, Leaflet closes the previously opened popup each time another is opened. The second is that, while your markers have popups bound to them, markerGroup does not, and even if it did, markerGroup.openPopup would only cause a single popup to open.
To get around the first problem, you can use the hack from this answer. If you place the following code at the beginning of your script (before you define your map) it will override the default behavior and allow you to open multiple popups at once:
L.Map = L.Map.extend({
openPopup: function(popup) {
this._popup = popup;
return this.addLayer(popup).fire('popupopen', {
popup: this._popup
});
}
});
Then, once you are able to open multiple popups, you can open all popups in markerGroup using the eachLayer method:
var markerGroup = L.featureGroup([testMarker,testMarkerTwo]).addTo(map);
markerGroup.eachLayer(function(layer) {
layer.openPopup();
});

I've somewhat successfully integrated the jQuery Infinite Ajax Scroll plugin into my development site - it is used twice, first on the thread list on the left, second when you load up an individual topic - but I'm having trouble with the second ias instance here.
Basically the content of a topic is loaded via $.get and then rendered into the page, and then I trigger setupThreadDetailDownwardScroll() in JS which creates an instance of ias:
var iasDetail = jQuery.ias({
container: "#reply-holder",
item: ".post",
pagination: ".threaddetail-pagination",
next: ".load-next-inner-link a",
delay: 2000,
});
if (iasDetail.extension) {
iasDetail.extension(new IASPagingExtension());
iasDetail.extension(new IASTriggerExtension({
text: 'More Replies',
html: '<div class="scroll-pager"><span>{text}</span></div>',
offset: 10,
}));
iasDetail.extension(new IASNoneLeftExtension({html: '<div class="scroll-message"><span>No more replies</span></div>'}));
iasDetail.extension(new IASHistoryExtension({
prev: '.load-previous-inner-link a',
}));
}
iasDetail.on('load', function() {
$('#reply-holder').append(scrollLoading);
})
iasDetail.on('rendered', function() {
$('.scroll-loading').remove();
iasDetail.unbind();
})
But the problem is that this only works with whatever the first topic you load is - you'll get working pagination in the first thread, but then it'll fallback to anchor links when you open the next thread.
So I figured that I needed to rebind ias once this new content is inserted, and this is why I have added the unbind() call in rendered, and then I re-call setupThreadDetailDownwardScroll() whenever another thread is loaded. This doesn't work either though.
Is there a correct procedure here?
You are using jQuery.ias(...) which binds to the scroll event of $(window). In your case you probably want to bind to an overflow div. Therefor you should specify the scrollContainer like this:
$('#scrollContainer').ias(...)
Edit:
Based on you comment I took another look at it and might have found an answer. When you call jQuery.ias({...}); IAS gets setup and waits for $(document).ready to initialize. You say you want to initialize IAS in your setupThreadDetailDownwardScroll function. You can try to initialize IAS yourself with the following code
iasDetail.initialize();
Here's a simple fiddle to demo my situation...

What I'm doing is adding an event handler for current & future elements, using .on(). I want to be able to remove these event handlers for specific elements when something happens; in the case of the fiddle, when the radio button is selected, the event handler for the blue elements should be removed and clicking those elements should not do anything anymore.
It doesn't seem to be working :(
How do I remove the event handler attached to document that I created with .on() for those specific blue elements?
The signature for your .on() and .off() has to match.
These two do not match so the .off() call won't find matching event handlers to remove:
$(document).on('click', '.btn', function() {
update();
});
$(document).off('click', '.blue');
Note, the selector passed to .on() and .off() is different.
When using the dynamic form of .on() (where you pass a selector as an argument to .on()), you can't remove just part of the items. That's because there's only one event handler installed on the root element and jQuery can only remove the entire thing or not at all. So, you can't just .off() some of the dynamic items.
Your options are to remove all the event handlers with:
$(document).off('click', '.btn');
and, then install a new event handler that excludes the items you don't want such as:
$(document).off('click', '.btn:not(.blue)');
Or, teach the event handler itself how to ignore .blue items:
$(document).on('click', '.btn', function() {
if (!$(this).hasClass('blue')) {
update();
}
});
Be careful of how you attach your events; this works fine for me:
$('.btn').on('click', function() {
update();
});
$('#disable').on('change', function() {
$('.btn').off('click');
});
Only way seems to be:
$('#disable').on('change', function() {
$(document)
.off('click', '.btn')
.on('click', '.btn:not(.blue)', update);
});
I understand that this is a probably a noob-ish question, but I've had no luck with the other threads I've found on the same topic.
I've devised a workaround to hack a views exposed filter to hide and show products with a stock count of "0". The exposed filter for the stock count (input#edit-stock) is hidden with CSS and inside a custom block is a link to manipulate the form and trigger the query (with ajax). This is working great, but with one exception - after resetting the form with the views-provided "reset" button, toggle() will not rebind properly to the link, and click won't fire the first time. Works fine on the 2nd click. I'm sure that the solution is very simple, but I'm at a loss..
How to rebind toggle() effectively?
Sorry, I'm unable to provide a live example. Many thanks for any input.
CUSTOM BLOCK:
<a id="toggle" href="#">exclude</a>
JQUERY:
$(document).ready(function () {
var include = function () {
$('input#edit-stock').attr('value', 0).submit();
$('a#toggle').html('include');
};
var exclude = function () {
$('input#edit-stock').attr('value', '').submit();
$('a#toggle').html('exclude');
};
$('a#toggle').toggle(include, exclude);
$('input#edit-reset').live('click', function (event) {
$('a#toggle').unbind('toggle').toggle(include, exclude).html('exclude');
});
});
if i get the problem right you need to reset the toggle. Why instead of unbind toggle and rebinding it you just don't simulate a click if the link is == to include?
$(document).ready(function () {
var include = function () {
$('input#edit-stock').attr('value', 0).submit();
$('a#toggle').html('include');
};
var exclude = function () {
$('input#edit-stock').attr('value', '').submit();
$('a#toggle').html('exclude');
};
$('a#toggle').toggle(include, exclude);
$('input#edit-reset').live('click', function (event) {
//if the link is include, click it so that it resets to exclude, else do nothing
if ($('a#toggle').html() == 'include'){
$('a#toggle').click();
}
});
});

I try to use good lib jstree but i have some strange problem with dblclick binding.
Here is my code
$("#basic_html").jstree({
themes: {
url: "http://mywork/shinframework/shinfw/themes/redmond/css/jstree/default/style.css"
},
"plugins" : ["themes","html_data","ui","crrm","hotkeys", "core"],
});
$("#basic_html").bind("dblclick.jstree", function (e, data) {
alert(e);
alert(data);
});
When this code runs and i make dblclick for some node i can see 2 alerts. The first is object -right, the second is undefined - BUT i want receive data information.
Please, if some specialist solve this problem give me right way for correct use dblclick and receive "data" information about node who is i clicked.
Thanks
I recommend this approach . . .
$("#basic_html li").live("dblclick", function (data) {
//this object is jsTree node that was double clicked
...
});
First, you usually only need to know if the li was clicked so monitoring the event on the li will give you everything you need. Secondly, use live or delegate for the event binding so you can manipulate the tree without breaking the event.
Once you have the node that was double clicked (the this object) you can then use the built-in functions like this . . .
if (!jsAll.is_selected(this)) { return false; } //cancel operation if dbl-clicked node not selected
Where . . .
jsAll = $.jstree._reference("basic_html")
$("#basic_html").bind("dblclick.jstree", function (event) {
var node = $(event.target).closest("li");//that was the node you double click
});
that's the code you want.
