Ember cli contenteditable component, with placeholder and value binding. Use it just like an input or textarea, but it will autoresize for you.

Compatibility

* Ember.js v4.4 or above
* Ember CLI v4.4 or above
* Node.js v14 or above

$3

Version 3.0.0 targets ember octane apps only. If you need support for older ember versions, please see previous versions of this addon. Version 3.0.0 is based on the ember-content-editable-modifier addon.

Major changes as of 3.0.0:
- Breaking: it is no longer possible to use two way binding within components, so consuming apps need to handle updates by providing a @onChange function!
- Breaking: event handler names are changed to follow a consistent pattern
- internal rewrite

This addon supports events supported by the ember component model (except for keyboard events). See the ember documentation for details or the dummy app within the test folder for an example. As this addon uses keyboard events slightly renamed hooks are available as making use of the default hooks would override the addons implementation.

event | description | argument
-- | -- | --
onLengthExceeded | if maxlength is set, every action that exceeds the limit triggers this event | total numbers of character entered (number)
onEnter | triggers when the enter key is pressed | event
onEscape | triggers when the escape key is pressed | event
onKey | keydown event propagation | event
onPaste | triggers when content is pasted successfully (does not fire when maxlength is exceeded) | pasted text content (string)

`
.ember-content-editable:empty {
color: rgba(0,0,0,0.6);
}
`

Common Problems

These are some solutions to common problems browsers have with contenteditable elements.

$3

The tabindex attribute is bound to the element in the DOM, but only certain tags support it.

>The following elements support the tabindex attribute: A, AREA, BUTTON, INPUT, OBJECT, SELECT, and TEXTAREA.

So to use tabindex, you'll also need to set tagName to one of those.

$3

Try using whitespace: pre-line; or whitespace: pre-wrap; in your CSS.

$3

A solution to this is to call window.getSelection().removeAllRanges() after you call blur() on the element.

For example, if you have enter='endEditing' on your content-editable, the following action would prevent the newline and blur the element.

`
endEditing(contentEditable, event) {
event.preventDefault();
contentEditable.element.blur();
window.getSelection().removeAllRanges();
}
`

$3

Setting display: block;` in CSS seems to solve this.
