Why does Quill filter it's content?

问题:

When I use QuillJs to edit an existing HTML document, it removes the comments, indentations etc of the original HTML. Is there anyway to prevent this?

回答1:

Quill does not support arbitrary HTML. By default, anything that is not recognized will be converted (the <strong> tag to the <b> tag) when possible, or removed when not.

In Quill configuration options, use the configuration named formats. The formats defined in this property will create a whitelist, where anything not in it will be filtered. A list of all formats can be found here.

For more information, visit the following links:

• Suppress certain formats in Quill

To add support for new formats you will need to create a new one. See the following links to find out how this can be done:

• What, how and when to use static formats, formats and format on custom blot?
• Cloning Medium with Parchment
• Parchment API
• Native examples
• A emoji blot example

As a tip, if you want to create Blot, and you want to allow it to be only edited or removed as a whole, set your Blot to be a child of Embed.

I forgot to say something: If you are pasting content to the editor, you better take a look at the clipboard module.
