TinyMCE UndoManager. Get event to fire - javascript

I have made a webform that uses a TinyMCE editor. When the user clicks on a link to leave the page, I want a message to be displayed if he still has unsaved changes. For this, I was thinking of using the TinyMCE undoManager, http://www.tinymce.com/wiki.php/API3:class.tinymce.UndoManager
Essentially, I want the events onAdd, onUndo, OnRedo to fire. I will then keep track of the number of changes (if any) since the last save. But how do I get them to fire? Where do I set them up?
Also, it would be nice to have access to the hasUndo method in the rest of my javascript code. Again, not sure where to initiate this?
Not sure if it matters, but I'm using Django.
Edit: I have tried
tinyMCE.init({
...,
setup : function(ed) {
ed.UndoManager.onAdd(function(ed) {
ed.windowManager.alert('added.');
});
}
});
This gives me an error: Unable to get value of the property 'onAdd': object is null or undefined

I created a tinym fiddle for this: http://fiddle.tinymce.com/H0caab .
The solution is to use the oninit setting and to addresss the onAdd.add:
tinyMCE.init({
...
setup : function(ed) {
ed.onInit.add(function(ed) {
ed.undoManager.onAdd.add(function(ed) {
alert('added.');
});
});
}
});

Can't find element using UI hash in Marionette Layout

I'm not sure why I can't get the button element using my UI hash. This is what my Layout looks like:
Layout: App.Base.Objects.BaseLayout.extend({
// Rest of the code left out for brevity
ui: {
btnSave: "#btnSave"
},
events: {
"click #ui.btnSave": "onSave"
},
onInitialize: function () {
this.listenTo(App.vent, "DisableSaveButton", function(val) {
this.disableSaveButton(val);
},this);
},
disableSaveButton: function () {
this.ui.btnSave.prop("disabled",val).toggleClass("ui-state-disabled",val);
},
onSave: function () {
alert("saved!");
}
})
In VS2013, when my breakpoint hits the line inside disableSaveButton method, I entered $("#btnSave") into the Watch window and I was able to get the element back. I could tell because it had a length of 1. From this, I know the button is rendered. However, if I enter this.ui.btnSave into the Watch window, I would get an element with length of 0.
My BaseLayout object is basically a custom object extended from Marionette.Layout
Marionette version: 1.8.8
Any ideas why I can't find the button element using this.ui.btnSave?
Thanks in advance!
Got some help from a coworker and the issue might be because the element is out of scope. Basically, inside the Layout object, 'this' does not contain the element. We were able replace 'this.ui.btnSave' with '$("#btnSave",this.buttonset.el)' and that works fine. buttonset is the region that actually contains the html element.
This seems like an inconsistency because even though the ui hash didn't work, the click event utilizing the ui hash did work.
UPDATE 6/3/2015:
Another coworker of mine provided a better solution. Basically, in my Layout I use a display function to display my view. It looks something like this:
Layout: App.Base.Objects.BaseLayout.extend({
// Rest of the code left out for brevity
display: function() {
$(this.buttonset.el).html(_.template($("#buttonset-view").html(), {"viewType": viewType}));
}
})
Basically, I'm saying to set the html of my region, which is this.buttonset.el, to my template's html. As of now, my layout doesn't know any of the elements inside the region. It just contains a region which displays the elements. So there is some sort of disconnect between my layout and the elements in my region.
The correct solution, as opposed to my earlier workaround, is to simply add the following line of code at the end:
this.bindUIElements();
From Marionette Annotated Source:
This method binds the elements specified in the “ui” hash inside the
view’s code with the associated jQuery selectors.
So this final code looks like this:
Layout: App.Base.Objects.BaseLayout.extend({
// Rest of the code left out for brevity
display: function() {
$(this.buttonset.el).html(_.template($("#buttonset-view").html(), {"viewType": viewType}));
this.bindUIElements();
}
})
With this, I was able to finally able to retrieve my element using this.ui.btnSave.

jQuery dialog with <object>, cannot call dialog('close') from within object document

I have the following situation on a web application.
A dialog is built and opened on the fly when clicking on a link:
var dialogInitiator = $("<div id='dialog-initiator' style='background-color: "+bgcolor+";'>Loading...</div>");
dialogInitiator.appendTo(parentFrame);
dialogInitiator.dialog({
modal:true,
autoOpen: false
}).on('keydown', function(evt) {
if (evt.keyCode === $.ui.keyCode.ESCAPE) {
dialogInitiator.dialog('close');
}
evt.stopPropagation();
});
dialogInitiator.dialog('open');
Right after that, I load a new html page into the dialog, with an < object >, like this:
var objectFrame = $('<object style="border: 0;width:'+(dlwidth-30)+'px;min-height:'+(dlheight-46)+'px;" type="text/html" style="overflow:auto;" data="'+url+'"></object>');
dialogInitiator.html(objectFrame);
Now, the "url" variable contains a link to this new html document. When that page is ready, it will focus on an input field. This prevents the ESCAPE key from closing the dialog. So, I am trying to manually trigger the .dialog('close') event on escape keypress.
I do the following, from within the loaded document:
$('#dialog-initiator', window.parent.document).dialog('close');
It get the following error:
"Error: cannot call methods on dialog prior to initialization; attempted to call method 'close'"
Strange thing is, when i call:
console.log( $('#dialog-initiator', window.parent.document).html() );
it shows me the html from the dialog. So it actually IS initiated.
Well, I have tried to fix this error with the help of Google, but without success. I guess my situation is quite specific.
Note: we are forced to use the technique with loading this whole webpage into the dialog due to older functionality we used in modalDialogs. Since they are depricated in the latest Google Chrome, we've built a temporary solution with jQuery dialog.
I hope someone can help me out. I appreciate it!
You can try a global method created after the modal is created
dialogInitiator.dialog({
modal: true,
autoOpen: false,
create: funtion(e,ui) {
window.closeMyDialog = function() {
$('#dialog-initiator').dialog('close');
};
}
})...
Then call it by doing window.parent.closeMyDialog();.
Why not use JQuery UI? It's easier than making your own.

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 :)

jQuery mobile 1.1.0 slider: JS-object properties access?

EDIT: This could be seen as a pure javascript objects question. The code can be found here:
jquery.mobile-1.1.0.js
I need to access properties of a jQuery mobile JS-object but is not sure how that is possible. In the jquery.mobile-1.1.0.js and mobile.slider is the following (see extend on line 5967):
$.widget( "mobile.slider", $.mobile.widget, {
...
_create: function() {
...
$.extend( this, {
slider: slider,
handle: handle,
valuebg: valuebg,
dragging: false,
beforeStart: null,
userModified: false,
mouseMoved: false
});
Primarily the property I would like to read is the "dragging".
I know i can execute the methods using:
$("#slider").slider("refresh")
Is there a similair way to access the properties?
Thanks
How to react to user dragging the slider, without having to bind mouse-/tap-events, but instead using the JQM functionallity already in place.
To access the "dragging" variable of the JQM slider object I made an extension to the object as follows:
$(document).bind("mobileinit", function(){
$.mobile.slider.prototype.getDragging = function(){
return this.dragging;
};
});
With that in place, I can choose to react to changes only done by the user:
$("#slider").live('change',function(){
if($("#slider").slider("getDragging"))){
console.log('User is dragging slider to new value');
}
else {
console.log('Program changed value. (or user typed in visible textbox)') ;
}
});
With the slider textbox hidden, this give me the benefit of:
Using the "change"-event to react to user dragging without being triggered when my program change the slider value.
When my program is going to change the slider value, it can first check that the user is NOT currently dragging the slider.

ExtJS: starting HtmlEditor defaulting to source

I'm using ExtJS 3.2.1 and I need a component almost identical to the bundled HtmlEditor, with one exception: it must start editing the HTML source code directly. The reason I don't use a normal TextArea is that the user should be able to preview the result of his actions before submitting.
I've tried calling toggleSourceEdit(), as per ExtJS documentation, with no success. Debugging, I see that the editor object has the sourceEditMode property set to true, and the Source Edit button seems as if it was "pressed", but clicking on it does not render the typed HTML, and clicking it again goes to the Source Mode.
I've tried calling toggleSourceEdit() after the container show() method, on the container afterLayout listener and on the editor afterRender listener. I've tried also calling it on another button that I added to the container. The result is the same on every try.
The only other option I see is updating ExtJS to 3.3.0, but I haven't seem anything related on the changelogs. Either way, it's going to be my next step. EDIT: The app had another problems when updating, we'll make a bigger effort to update later. As of right now, we are using the HtmlEditor in its original setting.
Thanks!
ran into the same problem (using 3.3.0 by the way)
stumbled upon a fix by dumb luck. i have no idea why this works, but second time is the charm. call it twice in a row to achieve the desired effect..
HTMLEditor.toggleSourceEdit(true);
HTMLEditor.toggleSourceEdit(true);
hope that helps!
Rather calling toggleSourceEdit(), try to setup the configuration while you create HtmlEditor Object
Using toggleSourceEdit() caused some problems for me. One was that this seemed to put the editor somewhere in limbo between source edit and WYSIWYG mode unless I used a timeout of 250ms or so. It also puts the focus in that editor, and I don't want to start the form's focus in the editor, especially since it's below the fold and the browser scrolls to the focused html editor when it opens.
The only thing that worked for me was to extend Ext.form.HtmlEditor and then overwrite toggleSourceEdit, removing the focus command. Then adding a listener for toggling to the source editor when the component is initialized. This is for Ext 4.1 and up. For older versions, replace me.updateLayout() with me.doComponentLayout().
var Namespace = {
SourceEditor: Ext.define('Namespace.SourceEditor', {
extend: 'Ext.form.HtmlEditor',
alias: 'widget.sourceeditor',
initComponent: function() {
this.callParent(arguments);
},
toggleSourceEdit: function (sourceEditMode) {
var me = this,
iframe = me.iframeEl,
textarea = me.textareaEl,
hiddenCls = Ext.baseCSSPrefix + 'hidden',
btn = me.getToolbar().getComponent('sourceedit');
if (!Ext.isBoolean(sourceEditMode)) {
sourceEditMode = !me.sourceEditMode;
}
me.sourceEditMode = sourceEditMode;
if (btn.pressed !== sourceEditMode) {
btn.toggle(sourceEditMode);
}
if (sourceEditMode) {
me.disableItems(true);
me.syncValue();
iframe.addCls(hiddenCls);
textarea.removeCls(hiddenCls);
textarea.dom.removeAttribute('tabindex');
//textarea.focus();
me.inputEl = textarea;
} else {
if (me.initialized) {
me.disableItems(me.readOnly);
}
me.pushValue();
iframe.removeCls(hiddenCls);
textarea.addCls(hiddenCls);
textarea.dom.setAttribute('tabindex', -1);
me.deferFocus();
me.inputEl = iframe;
}
me.fireEvent('editmodechange', me, sourceEditMode);
me.updateLayout();
}
})
}
Then to use it:
Ext.create('Namespace.SourceEditor', {
/*regular options*/
listeners: {
initialize: function(thisEditor) {
thisEditor.toggleSourceEdit();
}
}
});
htmlEditor.toggleSourceEdit(true);
one time should be enough if you do this listening to the afterrender event of the editor.
