Via e-mail, I received a pointer to an interesting cross-browser rich text editor. It works on Internet Explorer 5.5+ and Mozilla 1.3+. Although it’s simple, it seems to work nicely. The resulting code is reasonable in Mozilla, but will still need to be tidied up.
This kind of text editors became a fever among the customers of the company I’m currently working for. I’ve tested dozens of solutions, but none was simple and extensible enough to be adopted as company standards. So I’m maintaining a lot of different components now. I will definitely have to take a look at this new editor.
