How to reinitialize highlight.js? - syntax-highlighting

My website is generating some content dynamically, so I have to somehow launch the highlight.js plugin again after loading it.
This code is used to launch the highlighter:
hljs.initHighlightingOnLoad();
I tried to do something like hljs.initHighlighting(); to do this again but it does not work.

You must set called to false first:
hljs.initHighlighting.called = false;
hljs.initHighlighting();

You can reinitialize all of the codeblocks like this.
$(document).ready(function() {
$('pre code').each(function(i, e) {hljs.highlightBlock(e)});
});
or if you have a div with an ID of myBlock, you can do this.
$(document).ready(function() {
$('#myBlock').each(function(i, e) {hljs.highlightBlock(e)});
});

i hope this could solve your problem..
you have to use
hljs.highlightAll()
since, hljs.initHighlightingOnLoad() is deprecated since version 10.6.
if you're using react, you could apply at componentdidMount..
useEffect(() => {
hljs.highlightAll()
}, []);
or, if another framework, please call that function when page loaded.

simple modal loader

I am new in using jquery. I am trying add in the simplemodal.js (Eirc Martin's simple modal) a function called 'jBox' that will take the data (ie link) and options and using ajax will load the content into the modal container. This way I want on my pages in several places easy call this function
jBox = function(address, options){
$.get(address, function(data) {
$.modal(data);
});
};
});
The code is working fine, but i would like to add a loading image before the content is fully loaded. There is a lots of similar posts about loader/ spinner in simplebox but none of the works for me.
I was trying following code
$('#test').load('<img src="loader.gif">').html(data);
$('#test').modal();
But, some way, it doesnt work for me. Any ideas what I am doing wrong? Thanks
I use the ajaxStart and ajaxStop events.
$("body").on({
ajaxStart: function() {
$(this).addClass("loading"); // so page knows it's in loading state
// .. your modal code
},
ajaxStop: function() {
$(this).removeClass("loading"); // not it loading state anymore
// .. What you should do if loading is done. (eg. hide modal)
}
});
In this case I set the body class to 'loading'. So you can do some magic in css if you like.
I tend to use it to disable forms as well.
body.loading div.some-class {
// your special style for during loading
}

jQuery Delegate not binding like I want it to

Using jQuery 1.7
I'm having trouble binding a Click event to some dynamically loaded content.
I've looked around, tried .live, .delegate and .on, and I just can't get it to work.
This is my code:
$(".fileexplorer_folderdlg").delegate(".delete", "click", function () {
console.log("Hello world!");
});
The thing is, .fileexplorer_folderdlg is dynamically loaded. If I use .fileexplorer (not dynamically loaded), it works, but I have more elements with the .delete class that I do not wish to bind to (and neither element classes can be renamed or changed for various reasons).
I also tried using .fileexplorer_folderdlg .delete as the .delegate selector, didnt work either!
Of course I could just add another unique class to the elements I wish to bind to, but this really should work, right?
I believe this would work:
$(document).on('click', '.delete', function() {
if ($(this).closest('.fileexplorer_folderdlg').length) {
console.log('hello, world!');
}
});
or even just:
$(document).on('click', '.fileexplorer_folderdlg .delete', function() {
console.log('hello, world!');
});
As you've found, you can't bind on .fileexplorer_folderdlg because it's dynamic. You therefore need to bind on some static element that will contain that element at some point in the future.
Instead, this binds on the document (but will unfortunately fire for every single click on the document thereafter).
EDIT by Jeff
Although the code above did not work, modifying it a bit did the job, although not the most desirable solution.
$(document).on('click', '.delete', function () {
if($(this).closest(".fileexplorer") != null)
console.log("Thanks for your help!");
});
It works, but this event is fired for all other .delete classes, of which there are many. What I do not understand though, is why using .fileexplorer_folderdlg .delete did not work!

Joomla custom admin button actions

I have no idea why this doesn't work, but none of my custom button actions (tasks) do anything in my component. In my view.html.php file I have:
JToolBarHelper::custom('reports.export_csv', 'csv', '', 'CSV', false);
JToolBarHelper::custom('reports.export_mailchimp', 'mailchimp', '', 'Mailchimp', false);
Then in my ReportsControllerReports file I have 2 methods (not just 2, there are some others but they aren't relevant), export_csv() and export_mailchimp(). Whenever I click the buttons I get a JS error which I assume is preventing the action from executing the code in those methods. Something about "b is undefined". I cannot find any differences between my code and that used in other Joomla (core) components, so if anyone could shed some light on this issue it would be greatly appreciated (as usual, the Joomla forums are totally useless).
#Cfyzz solution works.
I added this to view file:
<script type="text/javascript">
Joomla.submitbutton = function(pressbutton) {
switch(pressbutton) {
case 'google':
window.location = '<?=JRoute::_( 'http://google.com', false );?>';
break;
case 'stackoverflow':
window.location = '<?=JRoute::_( 'http://stackoverflow.com', false );?>';
break;
}
}
</script>
and this in view.html.php
JToolBarHelper::cancel('stackoverflow', 'Go Overflow');
JToolBarHelper::custom('google', 'checkin', '', 'Go Google', false);
Obviously you dont have to use "JRoute::_(" in this situation. I replaced inner links with 2 samples so it`s easier to understand.
You should override the Joomla's JS framework behavour
You should use the function in your custom JS file:
Joomla.submitbutton = function(pressbutton) {
switch(pressbutton) {
case 'export_cvs':
URL = JURI::base.'index.php?option=yourController&task=export_cvs&....
$.ajax({
url: URL,
type: post, etc
});
}
}
In my component everytrhing is ok and working properly

How to make full CKEditor re-initialization?

Please help me - I need to make full re-initialization of CKeditor. I don't want to make re-initialization of instances of CKeditor, but I want fully reload it. Is there any way to implement it?
I tried to made next:
delete window.CKEDITOR;
and then:
//clear for old sources
$('script[src*="/includes/contentEditor/ckeditor/"]').each(function() {
$(this).remove();
});
$('link[href*="/includes/contentEditor/ckeditor/"]').each(function() {
$(this).remove();
});
//load CKeditor again
contentEditor.loadjscssfile('/includes/contentEditor/ckeditor/ckeditor.js', 'js');
contentEditor.loadjscssfile('/includes/contentEditor/ckeditor/adapters/jquery.js', 'js');
My method loads editor but some plugins does not work after reloading. Thanks for any help!
I have plugins and I don't need to fully reinitialize CKEditor either, just instances, are you doing it properly?
To remove my instance (my textarea is referenced by ID txt_postMsg):
$('#btn_cancelPost').click(function(){
CKEDITOR.remove(CKEDITOR.instances.txt_postMsg);
$('#txt_postMsg').remove();
$('#cke_txt_postMsg').remove();
});
Then I re-create the textarea, and after a 50ms timeout I call the constructor with the textarea again, plugins reload fine. We have some pretty complex plugins for flash/image editing so maybe there's an issue with your plugin?
My version:
$$("textarea._cke").each(function(Z) {
if (typeof(CKEDITOR.instances[Z.id]) == 'undefined') {
CKEDITOR.replace(Z.id, { customConfig : "yourconfig.js"});
} else {
CKEDITOR.instances[Z.id].destroy(true);
CKEDITOR.replace(Z.id, { customConfig : "yourconfig.js"});
}
});
try something like
for(var instanceName in CKEDITOR.instances)
CKEDITOR.remove(CKEDITOR.instances[instanceName]);
CKEDITOR.replaceAll();

I use CKeditor for dynamically edit different part of site. When I click on some area of the site it shows popup with CKeditor with content of this area above this area. When I save it I destroy instance of this editor, but if while editing I use link plugin CKeditor can't show editor without page refreshing. Chrome says - Uncaught TypeError: Cannot call method 'split' of undefined, Mozilla - x.config.skin is undefined(I try to set config.skin and it show another error - z is undefined).
I hope the full re-init can help.
P.S. Sorry I can find how to answer on your comment...
I've been looking for a way to re-initialize the editor and the only solution that I end up is to delete the instance and create a new ID.
Here's my code.
var editor = 'myeditor'
var instance = CKEDITOR.instances[editor];
if(typeof instance != 'undefined')
{
instance.destroy();
$(".cke_editor_" + editor).remove();
//make a new id
editor = (Math.random().toString(36).substr(2, 10););
}
CKEDITOR.replace(editor,
{
}
It's not perfect but it works.
Hope this helps.
This is my solution:
var editor = CKEDITOR.instances[your_ckeditor_id];
editor.mode = 'source';
editor.setMode('wysiwyg');
OR
var editor = CKEDITOR.instances[your_ckeditor_id];
editor.setData(editor.getData());

making jQuery plug-in autoNumeric format fields by time page loads

I've been messing around with autoNumeric, a plug-in for jQuery that formats currency fields.
I'd like to wire the plug-in so that all currency fields are formatted by the time the user sees the page, e.g., on load.
Currently, the default that I can't seem to get around is that fields are formatted upon blur, key-up or other action in the fields themselves.
I've been experimenting with the plug-in code and it looks like it will take this relative newcomer some time to resolve this, if at all.
Anybody on this?

Triggering 'focusout' event formats the field. Triggering 'change' does not work in the most recent version (1.7.4).
$('input.money').autoNumeric({aNeg: '-'}).trigger('focusout');
autoNumeric does all formatting after 'onchange' event fires. So all that you need is to programmatically fire this event. Like this:
$('input.money').autoNumeric({aNeg: '-'}).trigger('change');
Hope this helps!
I just ran into this problem myself. I had to make it more general, but this worked for me:
$('input.auto-numeric').ready(function(){
var format_options = {
aSign: '$'
};
$('input.auto-numeric').each(function(){
$(this).autoNumeric(format_options);
if($(this).attr('id')){
$(this).val($.fn.autoNumeric.Format($(this).attr('id'), $(this).val(), format_options));
}
});
});
This should work.
jQuery(function($) {
$('input.auto').ready(function(){
$('input.auto').autoNumeric();
var inputID = uniqueID; // use the jQuery.get() function to retrieve data
var formatValue = '1234.00'; // use the jQuery.get() function to retrieve data
if(jQuery().autoNumeric){
$('#id').val($.fn.autoNumeric.Format(inputID, formatValue));
}
else{
alert('plugin not available');
}
});
});

This is what I eventually did:
$(document).ready(function(){
$('input.auto').autoNumeric();
$('input.auto').each(function(){
var element = this
if(element.value !=""){
$('#'+element.id).val($.fn.autoNumeric.Format(element.id, element.value));
}
}
);
});
Another way of forcing formatting is using 'update' like
$(".input-numeric").autoNumeric('update');
In the current version 2.* and onward, this is done by default thanks to the formatOnPageLoad option that is set to true.
It's that simple ;)
