I want to include images in an aloha editable after a drop event, thus not using the toolbar button.
While some aloha commands may be executed programmatically, there is not so much doc about it and one must look into the code.
With the debugger i found that the relevant function is here so now i would go for copying the insertImg function body somewhere in my code and build my function.
On the other hand it would be much cleaner to reuse that code calling something like
Aloha.plugins.image.insertImg();
In a way similar to how it is done here. Is it possible to do such a thing?
A colleague explained me that there is nothing special required in order to insert an image. The function used by aloha is just a way to substitute jQuery and is not necessary.
Once the common/image plugin is loaded, it is sufficient to append an <img> tag inside the editable, also with jQuery, and the plugin will be triggered on it, adding the resize handle and showing the image toolbar when needed.

I am building a web app which uses Summernote to allow for HTML editing.
Users are allowed to add and edit JavaScript as well, using inline <script> tags. This works fine and can be done in the editor's "Code View" mode.
What I'd like to do is, in the preview/WYSIWYG mode, instead of having the script being executed, just display an image (or text) to let the user know that there's a script there.
Something like:
I looked around and I don't think this has been done before. Is it possible? Any pointers on how I could accomplish this?
Thanks!
https://github.com/summernote/summernote/issues/495 explains how to do it using CSS only.
I'm working on a JavaScript widget (I actually have several I'd like to update) and hope to distill the embed code snippet down to just a single <img> tag with JavaScript in the onload attribute. In the past I used a along with an <img> tag. Then I switched to just a <script> tag to make the widget non-blocking. I'm working on the <img> only option for usability reasons. It is easier to copy and paste to move the widget around if you don't have to switch into the source view of the WYSIWYG editor. It is also really nice to have something you can visually see in a WYSIWYG editor.
Here's an example of the current draft of the snippet:
<img id='NotablePAD80' class='NotablePAD' src='//dev.notable.webapp.msu.edu/n.png'
data-section='nathanlounds' onload="(function(d){ var i=d.getElementsByTagName('IMG')[0],
u='https://dev.notable.webapp.msu.edu/n.js',
j=i.previousSibling||i; if(j.src!==u) { var s=d.createElement('SCRIPT');
s.type='text/javascript'; s.src=u; i.parentNode.insertBefore(s,i);}})(document);" />
What is the best way to prevent the widget from executing pre-save in the WYSIWYG? The loading of the widget can't change the DOM within the editor.
My ideas:
Look from the presence of the tinyMCE variable. Don't process
widget if it is defined. TinyMCE is an editor I'd need to be
compatible with. But I'd likely need 'fixes' for other WYSIWYG too.
Examine the DOM and look for properties that are
only present within a WYSIWYG, such as being inside an iframe. But I need the widget to work within iframes.
There are problems with both of those options. TinyMCE may not be defined yet when my widget executes. The image load event gets triggered multiple times for some reason. Ultimately I'd love a solution that would work universally.
Thoughts? Brilliant solutions?
Check if a parent of the image has contentEditable enabled, or if the body of the document is in designMode
I'm creating a Wordpress plugin, which adds a metabox right under the post editor containing a button. The plugin also loads a Javascript file right below the closing </body> tag.
PURPOSE
At the moment, what I am trying to achieve with the plugin is simple. When a user enters content to the editor and then clicks the button inside the metabox, I want to modify the editor's content.
JS CODE
In its simplest form:
jQuery(document).ready(function($) {
$('#button').on('click', function(e) {
e.preventDefault();
var editor = tinyMCE.get("content");
editor.setContent(some_content);
});
});
PROBLEM
The problem is that editor variable returns undefined.
FIREBUG (when trying to set var editor)
wpActiveEditor : "content"
editors : [ ]
activeEditor : null
WHAT HAVE I TRIED
I have tried many, many things (also many small tweaks) found on Tinymce's documentation and here on Stackoverflow but the problem still remains the same.
Any help would be very appreciated.
PS. The content textarea is visible when running my tests.
When the Editor first loads with the "Text" mode active, tinymce does not get initialized, therefore you cannot use tinyMCE.get(), as opposed to the "Visual" mode.
(I hadn't noticed that it actually works on the "Visual" mode, as I was keep testing it on the "Text" mode)
So, a conditional statement is necessary to determine first which tab is active. I solved my problem with this method:
function setEditorContent(val) {
var $_editorTextArea = $('#content');
$_editorTextArea.is(':visible') ? $_editorTextArea.val(val) : tinyMCE.get('content').setContent(val);
}
Hope this answer will prevent some headaches :)
Well, a live example would help a lot.
This way i can only guess: It looks a bit as if you cannot get the editor you want.
There are two possible reasons that come into my mind:
The editor id you are using is not the id of your editor
To verify this you check the id of your editors soure html element (in most cases a textarea).If there is no id set tinymce will use "content" as default.
There iy no editor initialized at all
To verify this you can use console.log(tinymce.editors) in your javascript console. If no editor is initialized then you will get an empty array.
Many years later but maybe this will help someone...
In addition to everything said above some consideration needs to be paid to the JS event model. Consider:
TinyMCE may not initialize (and the tinymce global may not be available) until the document is done loading. The OP correctly wrapped calls in jQuery(fn), which will solve this. This is relevant if you're using an added framework that initializes and tries to manipulate the editors (like AngularJS directives).
Parts of initialization seem to be asynchronous so even if you wrap everything in jQuery(fn) the editors may not be available until later. WP loads Underscore as part of Backbone so wrapping initial attempts to locate editors in _.defer(fn) seems to get me lots of mileage. This could be done with the native JS setTimeout as well.
Beyond the fantastic answer by #m.spyratos, it may be helpful to note that you can hook mode change events (Visual/Text) by adding a jQuery click event handler to button.switch-tmce[data-wp-editor="my_editor_id"] and button.switch-html[data-wp-editor="my_editor_id"] for when the user selects Visual or Text, respectively. Your version may vary but I found that the textarea goes away when switching to Visual mode and the tinymce.editor instance goes away when switching to Text mode. Hooking to these events gives a persistent means to re-hook when the user decides to change modes.
As a quick reference, you can attach to the editor object (activeEditor or something in editors[], which is keyed by editor ID) to receive any and all changes in visual editor content with by hooking to the editor with editor.on('NodeChange keyup', fn) and a single event callback. I included blur in my solution as well, for posterity. The text editor content can be hooked with jQuery('textarea#my_editor_id').on('keyup', fn).
I have successfully managed multiple editors on a page that are entirely two-way bound entirely through JS; the editors are created with wp_editor and no initial content then loaded asynchronously (via AJAX in my case) and managed through multiple edit cycles without a server round-trip. This is possible, if not slightly convoluted.
Adding HTML/any tags to either side of selection - Javascript
The problem:
After creating a textarea box in my PHP/html file I wished to add a little more functionality and decided to make an textarea that can use formatting, for example
<textarea>
This is text that was inserted. <b>this text was selected and applied a style
via a button<b>
</textarea>
It doesn't matter what the tags are, (could be bubbles for all that I care due to the fact the PHP script, on receiving the $_POST data will automatically apply the correct tags with the tag as the style ID. Not relevant)
The Question/s
How can I create this feature using javascript?
Are there any links that may help?
And can, if there is information, can you explain it?
EDIT: Other close example but not quite is stackoverflow's editor and note that I do not wish to use 3rd party scripts, this is a learning process for me.
The tags that are inserted in the text are saved to a database and then when the page is requested the PHP replaces the tags with the style ID. If there is a work around not involving 3rd party scripts please suggest
And for the anti-research skeptics on a google search, little was found that made sense and there was Previous Research on SOF:

- Adding tags to selection
Thanks in Advance
<textarea> elements cannot contain special markup, only values. You can't apply any styling in a textarea.
What you'll need to do is fake everything that a text box would normally do, including drawing a cursor. This is a lot of work, as hackattack said.
You can do a lot if you grab jQuery and start poking around. Toss a <div> tag out there with an ID for ease and start hacking away.
I've never made one personally, but there is a lot to it. HTML5's contentEditable can maybe get you a good chunk of the way there: http://html5demos.com/contenteditable/
If you want to pass this data back to the server, you'll need to grab the innerHTML of the container and slap that into a hidden input upon submission of your form.
Here's other some things you can check out if you're just messing around:
tabindex HTML attribute, to get focus in your box from tabbing
jQuery.focus() http://api.jquery.com/focus/, to determine when someone clicks in your box
cursor: text in CSS for looks http://wap.w3schools.com/cssref/pr_class_cursor.asp
jQuery.keypress() http://api.jquery.com/keypress/, or similar for grabbing keystrokes
Edit: I think I completely misunderstood
If you're not looking for a rich text editor, and just want some helper buttons for code, maybe selectionStart and selectionEnd is what you're after. I don't know what the browser support is, but it's working in Chrome:
http://jsfiddle.net/5yXsd/
you can not do anything beside basic formatting inside a texarea. If you want complex formatting, look into setting a div's contentEditable attribute to true. Or you can make a wysisyg editor, but that is a big project. I strongly suggest using 3rd party code on this one.
I suggest you using the iframe to implement the WYSIWYG effect.
There is a property in iframe called designMode

While I'm well aware of how image maps work, and how to code them, etc...I find it a waste of time to use the image map creator to generate the Image Map code, then use HTML Tidy to tidy it, and then manually add all of the image attribute adding onclick events, having them return false, and making sure that the href="#", especially for large image maps.
Does anyone know of an image map creator that supports adding Javascript events (such as onclick) directly as opposed to just adding href urls, and then having to manual edit the code later?
You're trying to solve this problem the wrong way. This problem has nothing to do with creating image maps, it has to do with manipulating HTML. There's nothing unique about the tags in an imagemap.
So you have a bunch of stuff you want to do to some HTML, which happens to be an imagemap. Why not use something designed specifically to manipulate HTML, e.g. jQuery, to solve your problem?
"adding onclick events, having them return false, and making sure that the href="#"...
$('area').attr('href','#');
$('area').attr('onclick','.. whatever you want ...');
Just because jQuery is a javascript tool doesn't mean you can't use it for one-time tasks. Right click in Chrome, inspect element, "Copy as HTML."
Now let me add that using jQuery to add onclick attributes makes little sense, generally, since you should just be adding event handlers. But you could do this if you wanted to produce HTML that you will then copy/paste as hardcoded HTML. But I generally speaking, "onclick" should be avoided like the plague, especially with (as you say) imagemaps that have a lot of elements. It's just wasted bandwidth; since you're binding javascript handlers anyway you are obviously running javascript on your page already. Why not just use javascript to bind the handlers?
