How to get user-modify:read-write-plaintext-only behaviour in Firefox and IE

问题

Chrome/Safari support css:

-webkit-user-modify:read-write-plaintext-only , which can disable user paste rich text into a contenteditable div.

I do not know how to get it in firefox and IE.

回答1:

I believe you can use the -moz prefix for firefox

-moz-user-modify: read-write-plaintext-only;

And for IE (10+) you can use the -ms prefix

-ms-user-modify: read-write-plaintext-only;

It would also be proper to add it without the prefix for future proofing ;)

user-modify: read-write-plaintext-only;
