All Events

Listen with editor.attachEvent(name, handler) and stop listening with editor.detachEvent(name, handler). Inside a handler, this is the editor instance. A few events are cancellable: they receive a state object first, and setting state.returnValue = true tells the editor you handled it.

Example

editor.attachEvent("change", function () {
    document.getElementById("dirty").hidden = false;
});

// Some events let you take over. Set state.returnValue = true to say "handled",
// and the editor skips its own action.
editor.attachEvent("exec_command_newdoc", function (state, cmd, value) {
    state.returnValue = true;
    this.setHTMLCode("<p>New document</p>");
});

editor.detachEvent("change", myHandler);

Editing and lifecycle

Event	Handler receives	Fires when
`ready`	`()`	From core 2.6.10. Once, after the editor is built and its initial content is loaded. Fired asynchronously, so a handler attached right after new RichTextEditor(...) still receives it; one attached later is called on the next tick. config.onready receives it too.
`aftersethtml`	`()`	From core 2.6.10. After setHTMLCode replaced the content (also with { undoable: true }), once per call, and when the editor switches back from HTML source view. Not while source view is shown. A load is not an edit: no change event follows, and refreshes your handler makes become part of the loaded document.
`change`	`()`	The content changed: typing, a command, paste, undo. Debounced, so a burst of typing is one event.
`contentchange`	`()`	The content changed, reported by the content-safety plugin after its own pass.
`selectionchange`	`()`	The caret moved or the selection changed, including when a control is selected.
`focus`	`(event)`	The editing area gained focus (focusin from the editable document).
`blur`	`(event)`	The editing area lost focus (focusout).
`documentreplaced`	`(document)`	From core 2.6.10. The editing frame was moved and now has a NEW document (some plugins wrap the editing area in a panel at start-up). Listeners bound with editor.bindDocumentEvent / bindEditableEvent are re-attached for you; re-read anything you kept from getDocument() or getEditable().
`keydown`	`(event)`	A key went down inside the editing area. The native KeyboardEvent is passed through.
`keyup`	`(event)`	A key came up inside the editing area.
`keypress`	`(event)`	A character key was pressed inside the editing area.
`resize`	`()`	The editor was resized, including by the user dragging the resize corner.
`change_html_view`	`(isCodeMode)`	The editor switched between the WYSIWYG view and the HTML source view.
`copyheadinglink`	`(url, headingId)`	The user clicked the link button beside a heading (config.copyHeadingLink). url is the page address with #headingId; the editor has already tried to copy it to the clipboard.
`destroy`	`()`	destroy() was called. Disconnect your own listeners and sockets here.

Commands and dialogs

Event	Handler receives	Fires when
`exec_command`	`(state, command, value)`	Any command is about to run. Fires for every command, after the command-specific event below. Cancellable: set `state.returnValue = true` to handle it yourself.
`exec_command_<name>`	`(state, command, value)`	One named command is about to run, e.g. exec_command_newdoc, exec_command_bold. Use it to replace that command. Cancellable: set `state.returnValue = true` to handle it yourself.
`customdialog`	`(state, name, message)`	The editor is about to show one of its own dialogs or alerts, e.g. uploadfailed, uploadtoobig, reachmaxlength. Show your own instead. Cancellable: set `state.returnValue = true` to handle it yourself.
`charlimit`	`({ chars, words, overChars, overWords })`	The content passed a character or word limit set by the statistics plugin.

Uploads

Event	Handler receives	Fires when
`uploadprogress`	`(file, loaded, total)`	Bytes were sent, when the built-in uploader (file_upload_url) is in use and the browser reports progress.
`uploadretry`	`(file, attempt, error)`	An upload failed and is being retried, once per attempt. See uploadRetryCount.
`uploadcancel`	`(file, reason)`	An upload was cancelled: "cancel" from cancelUploads(), "removed" when its image was deleted, or "destroy".

Autosave

Event	Handler receives	Fires when
`autosaved`	`(timestamp)`	config.autoSave saved the content successfully.
`autosavefailed`	`(error, attempt)`	An autosave failed. attempt is 0 for the first failure, then 1, 2… as it retries.

Comments, track changes and revisions

Event	Handler receives	Fires when
`comment_added`	`({ id, text, author })`	A comment was added.
`comment_resolved`	`({ id })`	A comment was resolved.
`commentsonlychanged`	`(name, isCommentsOnly)`	The editor entered or left comments-only mode.
`review_decision_denied`	`(detail)`	A user without permission tried to accept or reject a tracked change.
`revision_snapshot`	`({ id, label, isNamed, createdAt })`	The revision history plugin stored a version.
`revision_history_sync_error`	`(detail)`	The revision history plugin could not reach its store.
`linkcheck`	`(issues)`	The link checker finished a pass; issues is the array it found.

Events in the last three groups come from plugins, so they only fire when that plugin is loaded. See exec_command for intercepting commands, Upload files for the upload options, and Configuration reference for autoSave.
