Bootsrap-select retains default options inside SetTimeout call - javascript

I am initializing a bootstrap-select control successfully on document.ready, but if I put it inside a setTimeout, all my options are ignored and the default options are used instead. I have tried debugging through the selectpicker js code but I can't figure out why this behavior is different. Please note I did see a very similar question but it was never successfully answered (Bootstrap-Select plugin not working with time consuming page load).
Here is my JS code:
$(document).ready(function () {
...display code
setTimeout(function () {
$('#mySelect').selectpicker({
container: 'body',
actionsBox: true,
liveSearch: true,
maxOptions: 16,
noneSelectedText: 'Sites',
selectedTextFormat: 'count>0'
});
...more display code
}, 100);
});
If I remove the setTimeout, the selectpicker displays with the options listed in the code, but if I leave the setTimeout, only the default options are used. Does anyone know why this is the case and how to get it to use the correct options when called from within the setTimeout?

Make all JavaScript work as normal on ajax content

I am working on a normal bootstrap theme which contains js slider, popup, text-rotation, masonry boxes etc..
The theme contains all relevant js library and main.js
All of these will load new content via ajax on user specified actions.
Here is the js/ajax for text-rotation:
In the example below i have to call the "$('.text-rotation').owlCarousel" in order to make the text-rotation to work properly.
function getCon(type,id)
{
var postData = { id: id, type: type}
$.ajax({
url : 'getcontent.php',
type : 'post',
data : postData,
success : function( resp ) {
var cont = $('#cont', resp).html();
$('#conta').after(cont);
$('.text-rotation').owlCarousel({
loop: true,
dots: false,
nav: false,
margin: 10,
items: 1,
autoplay: true,
autoplayHoverPause: false,
autoplayTimeout: 3800,
animateOut: 'zoomOut',
animateIn: 'zoomIn'
});
}
});
}
When not calling "$('.text-rotation').owlCarousel" it simply displays the text in list format.
In order to make the all the ajax load content work properly on all section i.e the slider, popup, etc.. i'll have to find the relevant theme functions and code them all on the respective ajax functions.
Is there any predefined js code which i may call on ajaxComplete so tha all ajax content works normal as it works on page load ??
I tried to call the main.js from "getScript" function inside the ajax success but not working..
The short answer is: no.
jQuery code acts on the DOM that exists when the code is run; if you add to the DOM later on there isn't any general-purpose way for jQuery code to go back and act on the new elements as though they had been there in the first place.
Your options are
rewrite your code to not depend on event bindings / manipulation of the AJAX-based content -- instead use delegated event bindings on elements that are always present
defer your main code init until after all AJAX calls have completed, so the DOM is already in place when you add your bindings
Write specific code to add necessary event bindings / modify newly added DOM chunks individually, as they're loaded

isUndoAvailable and isRedoAvailable undefined in handsontable

This is first time I use the handsonTable. I am trying to have a menu button with items undo/redo outside the context menu of the handsontable, and to make those items enabled/disabled, I need to check if the undo and redo are available after the table is rendered. At my surprise, when I call the functions isUndoAvailable() and isUndoAvailable inside the afterRender handler (as stated in the documentation https://github.com/handsontable/handsontable/wiki/Methods ), it causes the undefined JS error.
Here's a jsfiddle example of what I'm trying to do :
var container = document.getElementById('example');
var hot = new Handsontable(container,
{
data: data,
minSpareRows: 1,
colHeaders: true,
contextMenu: true,
afterRender: function(isForced){
if(this.isUndoAvailable()){
// do something
}
}
});
Please have a look at this jsfiddle example. Am I doing something wrong ?
Thanks in advance.
It seems you have stumbled upon an edge case, in which the undo/redo plugin (seems) to load only after the afterRender callback.
hot.isUndoAvailable()
This works in other callbacks, at least a few I tried just now.
Here's an updated version of your fiddle, just call isUndoAvailable outside of the afterRender callback and it will work.

after clicking {Permalink}, call function

I need to bind a function to initialize a js plugin after {Permalink} is clicked so Tumblr IPA "redirects" the browser to a new page, with the post details.
How can I do so? There's not so much documentation on how {Permalink} really works, whether it's ajax or whether it has some callback function (which I would appreciate).
Of course this would try to initialize before the "new" page is loaded. I think it's ajax though.
$("#{Permalink}").click(function() {
$('.jqzoom').jqzoom({
zoomType: 'standard',
lens:true,
preloadImages: false,
alwaysOn:false
});
});
{Permalink} renders a string that is the URL to the post: http://sample.tumblr.com/post/123
For reference, Tumblr theme operators don't have anything to do with javascript. They render mainly strings.
You need to bind the actual element that is clicked:
HTML
...
jQuery
$(".permalink").click(function() {
...
});

jQuery - bxSlider plugin reloadSlider issues

I'm using jQuery with the bxSlider plugin, here is the link to it just incase: http://bxslider.com/
I'm trying to reload the slider and my custom pager after I've removed certain slides from it.
Here is what I have tried:
$(function() {
var slider = $('#slider').bxSlider({
pagerCustom: '#bx-pager'
});
$('.list').on('click', '.delete', function() {
image = $(this).closest('li').find('[type="hidden"]');
// image.attr('id') contains a string: image-0, image-1, image-2, etc.
$('#slider, #bx-pager').find('.' + image.attr('id')).remove();
slider.reloadSlider({
pagerCustom: '#bx-pager'
}); // I have also tried: slider.reloadSlider();
});
});
It works partially. What happens is the slider gets reloaded just fine but it removes the pager completely when it runs the reload.
Thank you very much for any help.
As long as I see, this is a bug in bxSlider, in fact, when you call the reloadSlider method, internally are called the methods destroySlider and init.
In the destroySlider method the pagerEl element is destroyed, this is right if you are not using a custom one, because it is recreated programmatically in the init method, but if you are using a custom one it can't be recreated programmatically.
I ended up modifying the destroySlider method to check if a custom pager is used, in this case it must not be deleted.
Here is the before (line 1294):
if(slider.pagerEl) slider.pagerEl.remove();
And after:
if (slider.settings.pagerCustom === '') {
if(slider.pagerEl) slider.pagerEl.remove();
}
I'll post the bug on GitHub as soon as I have the time.

CKEditor Change Config Setting on Focus / Click

I need to be able to change the filebrowserUploadUrl of CKEditor when I change some details on the page, as the querystring I pass through is used by the custom upload process I've put in place.
I'm using the JQuery plugin. Here's my code:
$('#Content').ckeditor({
extraPlugins: 'autogrow',
autoGrow_maxHeight: 400,
removePlugins: 'resize'
});
$("#Content").ckeditorGet().on("instanceReady", function () {
this.on("focus", function () {
// Define browser Url from selected fields
this.config.filebrowserUploadUrl = filebrowserUploadUrl: '/my-path-to-upload-script/?ID1=' + $("ID1").val() + '&ID2=' + $("#ID2").val();
});
});
This works fine the first time, but if I come out of the dialogue and change the value of #ID1 and #ID2, it keeps the previous values. When I debug, the filebrowserUploadUrl is set correctly, but it doesn't affect the submission values. It seems the config values are cached.
Is there any way to change a config value on the fly?
Currently I don't see any possibility to change this URL on the fly without hacking.
Take a look at http://dev.ckeditor.com/browser/CKEditor/trunk/_source/plugins/filebrowser/plugin.js#L306
This element.filebrowser.url property is set once and as you can see few lines above it will be reused again. You can try to somehow find this element and reset this property, but not having deeper understanding of the code of this plugin I don't know how.
Second option would be to change this line #L284 to:
url = undefined;
However, I haven't check if this is the correct solution :) Good luck!
BTW. Feel free to fill an issue on http://dev.ckeditor.com.
I solved this by reloading the editor whenever a change occurred; I actually went through the source code for the browser plugin etc, but couldn't get any changes to work (and of course, I really didn't want to change anything for future upgrades).
function setFileBrowserUrl() {
// Remove editor instance
$("#Content").ckeditorGet().destroy();
// Recreate editor instance (needed to reset the file browser url)
createEditor();
}
function createEditor() {
$('#Content').ckeditor({
filebrowserUploadUrl: '/my-path-to-upload-script/?ID1=' + $("ID1").val() + '&ID2=' + $("#ID2").val(),
extraPlugins: 'autogrow',
autoGrow_maxHeight: 400,
removePlugins: 'resize'
});
}
Then I call setFileBrowserUrl every time the relevant elements on the page change. Not ideal, but it works for my purposes :)
