ckeditor - onpaste event - ckeditor

Does anyone know how I can attach an onpaste event in CKEditor 3.x?
I basically want to grab CTRL + V data and add few text to it and then add it to the editor.
I have looked around but have not found a definitive answer. CKEditor forum is of not much help.

This should do the trick
var editor = CKEDITOR.instances.YourInputControlName;
editor.on('paste', function(evt) {
// Update the text
evt.editor.setData(evt.editor.getData() + ' your additional comments.');
}, editor.element.$);

Your both examples are a little bit synthetic.
At first, editor.getData() gets all the content of editor, so if you want to process only pasted data, you need to get ev.data.html and paste to correct place.
editor = CKEDITOR.instances.editor1;
editor.on('paste', function (evt) {
var editor = evt.editor;
evt.stop(); // we don't let editor to paste data, only for current event
// show loader that blocks editor changes
$.post('clean.php', {html: evt.data.html}, function (data) {
editor.insertHtml( data.html ); // text will be inserted at correct place
// hide loader
}, 'json');
});
Don't use functions editor.setReadonly(true/false), you won't be able to paste text in correct place (in cases with async data processing).

This example edits the content to be pasted by removing all img elements.
CKEDITOR.on('instanceReady', function (ev) {
ev.editor.on('paste', function (ev) {
ev.data.html = ev.data.html.replace(/<img( [^>]*)?>/gi, '');
});
});

editor = CKEDITOR.instances[id];
editor.on('paste', function (evt) {
evt.stop();
var data = evt.data.dataValue;
if (window.chrome || window.safari) {
// removing span wrapper on webkit browsers.
data = $(data).html();
}
evt.editor.insertHtml(data);
});

I know it's an old question, but thought I'd add my version of aliaksej's answer as it allows the use of a custom 'cleaner' - it didn't quite work for me until I modded it as below.
editor = CKEDITOR.instances[id];
editor.on('paste', function (evt) {
evt.stop();
$.post('/actions/clean.php', {html: evt.data.dataValue}).done(function (data) {
evt.editor.insertHtml(data);
}, 'json');
});

Why Doesn't Javascript DOM 2 "Click" Event Work

My question is, Why doesn't the click event work when other events do work using the same code? Consider the following code examples from http://www.pricelearman.com/__dev (2 underscores)
For Square 2 using "click" event
function showWorkPane() {
var _workID = document.getElementById("workID");
_workID.addEventListener("click", showWorkPaneHandler, false);
}
function showWorkPaneHandler(e) {
var _workPane = document.getElementById("workPane");
e.preventDefault();
_workPane.style.display = "block";
}
Clicking on the link "Work" does not show the workPane.
For Square 3 using "mouseover" event
function showAboutPane() {
var aboutID = document.getElementById("aboutID");
aboutID.addEventListener("mouseover", showAboutPaneHandler, false);
}
function showAboutPaneHandler(e) {
e.preventDefault();
var v = document.getElementById("aboutPane");
v.style.display = "block";
}
Rolling-Over the link "ABOUT" shows the aboutPane hover effect as expected
For Square 4 using "mousedown" event
function showConnectPane() {
var connectID = document.getElementById("connectID");
connectID.addEventListener("mousedown", showConnectPaneHandler, false);
}
function showConnectPaneHandler(e) {
e.preventDefault();
var v = document.getElementById("connectPane");
v.style.display = "block";
}
Holding mouse down on the link "CONNECT" shows the connectPane as expected
What am I missing about the click event. It's counterintuitive to me that it would not follow the same pattern as the other mouse events.
I'm trying to preclude interference from the link's default action by using e.preventDefault();
I know a click event is a sequence of simple events: mousedown,mouseup,click.
Is there something blocking this sequence?
The full code can be reviewed at http://www.pricelearman.com/__dev (2 underscores). The code may not be optimum, but it is functionally correct – binding is accomplished and functions are called, etc – else the above code would not be working at all.
Thanks for your time and expertise. This is a vexing question to me. It seems so fundamental and simple. I'm new to javascript and I must be missing something.
For Square 2 using "click" event
function showWorkPane() {
var _workID = document.getElementById("workID");
_workID.addEventListener("click", showWorkPaneHandler, false);
}
function showWorkPaneHandler(e) {
var _workPane = document.getElementById("workPane");
e.preventDefault();
_workPane.style.display = "block";
}
Clicking on the link "Work" does not show the workPane.
Well what I currently can find at http://www.pricelearman.com/__dev/_js/main.js is
// Show work navigation
function showWorkPane() {
var workID = document.getElementById("workID");
workID.addEventListener("mouseover", showWorkPaneHandler, false);
// ^^^^^^^^^
}
function showWorkPaneHandler(e) {
e.preventDefault();
var v = document.getElementById("workPane");
v.style.display = "block";
}
Looks quite obvious to me why click events show no effect. There are none bound.

jquery each on new elements not working

$('.collapse').each(function() {
var title= $(this).siblings('.accordion-heading').find('a');
$(this).on('show hide', function (e) {
if(!$(this).is(e.target))return;
title.parent().toggleClass('active', 300);
title.parent().hasClass('active') ? $('input.party').prop('value', '') : $('input.party').val(title.siblings('.delete').prop('id'));
var id = title.siblings('.delete').prop('id');
var data = {id: id};
$.post("times.php", data, function(result) {
if(title.parent().hasClass('active')){
$('.times').html('');
} else {
$('.times').html($.parseJSON(result));
}
})
})
})
So I am adding a new accordion-group to my html by adding a new party and I wan't all this to work on the newly added elements as well. I didn't find topics that could help me since it is a bit more specific than any random each function (I think).
This future elements thing is new to me, so I would appreciate some explanations or a good link to a place other that the jquery website which I already checked.
Thank you for your time!
Basically what I want to do this replace $(this).on('show hide', function (e) { with something like $(document).on('show hide', $(this), function (e) {. What I just wrote doesn't work though.
If it is just about the event handler, then you can use event delegation to capture the event on dynamically created elements as well.
There is not reason why you have to use .each here, so just omit it:
$(document.body).on('show hide', '.collapse', function() {
var title = $(this).siblings('.accordion-heading').find('a');
if(!$(this).is(e.target))return;
// rest of the code...
});
this will apply on any new objects matching selector
jQuery(document).on('show hide', '.accordion-heading a', function(event){
...
});

In jQuery, how can I create a custom event with a default?

The Event object in jQuery has this helpful preventDefault() method that prevents the default behaviour, obviously.
This is usually used to prevent click events from performing the browser default behaviour.
It seems like it would also be useful for custom events as well.
The task I'd like to achieve with this behaviour is a separate concern but I will explain it as an example for the behaviour I'm looking for:
I have a simple plugin that creates a popup out of a div. I found it on the internet.
$(selector).pop();
I have hacked it to close when you click on anything but a child of the popup, and to prevent default click behaviour on the clicked element.
function closeInactivePop() {
var foundAny = false;
jQ.each(function (i) {
var $this = $(this);
if ($this.hasClass('active') && ! $this.data('activePop')) {
$this.removeClass('active');
foundAny = true;
}
});
return foundAny;
}
$('body').click(function(){
// If we closed any, cancel the propagation. Otherwise let it be.
if (closeInactivePop()) {
$(document).trigger('jQuery.pop.menuClosed');
return false;
}
});
(Now that I paste it I realise I could have done this a bit better, but that notwithstanding).
Now I have added a new plugin that draws a colour picker inside the popup. Except the DOM that this colour picker creates is not inside the popup; it is only inside it visually. The DOM structure is separate.
In the aforementioned hack I would prefer to in fact fire another event, one whose default behaviour is to close the popup.
function closeInactivePop() {
var foundAny = false;
jQ.each(function (i) {
var $this = $(this);
if ($this.hasClass('active') && ! $this.data('activePop')) {
$(document).trigger('jQuery.pop.menuClosed');
$this.removeClass('active');
foundAny = true;
}
});
return foundAny;
}
$('*').click(function(e) {
var $this = $(this);
// This bit is pseudocode, where the Function is the default behaviour
// for this event.
// It is helpful that $this is actually the clicked element and not the body.
$this.trigger('jQuery.pop.menuBeforeClose', function() {
// if we run default behaviour, try to close the popup, or re-trigger the click.
if (!closeInactivePop()) {
$this.trigger(e);
}
});
});
Then I could later do
$('#colour-picker').bind('jQuery.pop.menuBeforeClose', function(e) {
e.preventDefault();
});
And this would prevent the closeInactivePopup default behaviour running when the target of the original click event was the colour picker or something inside it.
Can I do this somehow, even hackily?
I doubt that there is a native way to do that. However, you can either use "triggerHandler()" instead of "trigger()", which provides the ability to return values from the event handlers. Another relatively simple solution is to pass a custom "event" object that can be used to cancel the planned action:
function Action() {
var status = true;
this.cancel = function() { status = false; };
this.status = function() { return status; };
}
$('button').click(function() {
var action = new Action();
$(this).trigger('foo', [action]);
if (action.status()) {
// ... perform default action
}
});​
In the event handler:
$('*').bind('foo', function(event, action) {
action.cancel();
});

Ajax file upload is not working when used the second time

I'm using this jquery plugin ajaxFileupload in our project. My design is I have a file upload control and set the opacity to 0.01 and then using an anchor link, I trigger the file upload control click event. This works fine until I try to click the anchor link the second time which it doesn't open the file dialog box.
Here is my code.
$(".btnUpload").live("click", function () {
$(".lblUploadError").text("");
$(".fleAttachment").trigger("click");
});
$(".fleAttachment").change(function () {
var reg = /^.*\.(jpg|JPG|gif|GIF|jpeg|JPEG)$/;
var vals = $(this).val(),
val = vals.length ? vals.split("\\").pop() : "";
if (reg.test(vals) == false) {
$(".lblUploadError").text("Invalid Image Type. We only accept .GIF or .JPG");
} else {
ajaxFileUpload();
eval($(".btnRefreshAttachmentList").attr("href"));
}
});
I don't see any error in the console so it makes it difficult to debug it.
Change
$(".fleAttachment").change(function() {
to
$(".fleAttachment").live('change', function() {
$( document ).on( "click", ".fleAttachment", function() {
//--> Logic Here // jQuery 1.7+
});
this.value="";
at the end should work

Skip some tags with stripTags() function in prototypejs

I've successfully implemented a bit of code that strips all HTML from a pasted string using stripTags(). My next goal is to mark a few tags with white flags so they get ignored on 'paste' event using .wrap() to augment the function.
I'm using prototype.js as a framework and have slowly been working through the growing pains of learning both the framework and javascript, but this issue has presented a bit of a roadblock.
I've googled around a bit and found what looks like two great solutions, but I don't seem to be implementing them correctly.
Found solutions:
http://perfectionkills.com/wrap-it-up/ (function to indicate tags to remove)
and
http://pastebin.com/xbymCFi9 (function to allow tags to keep)
I pretty much copied and pasted from the latter.
If I pull the 'br' from the code, then the regex is ignored and all html is stripped. If I leave it, nothing gets pasted.
Here is what I've pieced together (and I feel silly for not being able to figure this out!).
String.prototype.stripTags = String.prototype.stripTags.wrap(
function(proceed, allowTags) {
if (allowTags) {
if (Object.isString(allowTags)) allowTags = $w(allowTags)
this.gsub(/(<\/?\s*)([^\s>]+)(\s[^>]*)?>/, function(match) {
if (allowTags.include(match[2].toLowerCase()))
return match[1] + match[2] + match[3] + '>'
})
} else {
// proceed using the original function
return proceed();
}
});
WysiHat.Commands.promptLinkSelection = function() {
if (this.linkSelected()) {
if (confirm("Remove link?"))
this.unlinkSelection();
} else {
var value = prompt("Enter a URL", "http://www.alltrips.com/");
if (value)
this.linkSelection(value);
}
}
document.on("dom:loaded", function() {
var editor = WysiHat.Editor.attach('event_desc');
var toolbar = new WysiHat.Toolbar(editor);
editor.observe("paste", function(event) {
var el = $(this);
setTimeout(function() {
var pText = el.innerHTML.stripTags('br');
//alert(pText);
$('event_desc_editor').update(pText);
$('event_desc').setValue(pText);
}, 0);
});
(You may recognize the WysiHat code from 37Signals text editor)
note: you can see the alert commented out. If I do alert the ptext, I get 'undefined' returned.
So I've given up on and moved to a regex solution:
el.innerHTML.replace(/<(?!\s*\/?\s*p\b)[^>]*>/gi,'')
