Sory for my bad english!
How to make (simply, font color,size,bold,italic,underline,url,and image,undo,redo) tiny editor?
Is there any website with tutorial?

There is nothing tiny about it ;)

References and tutorials on developing rich text editors are rare and extremely difficult to find (I never found one till today). You should check out the open-source rich text editors and try to understand what they do in the sourcecode.

An example of an open-source WYSIWYG editor:

Try googling though to find the (maybe) one tutorial on the web on this subject? If you found it, feel free to post it below for others (including myself)!


Finally found one: http://www.webreference.com/programming/javascript/gr/column11/


This one is better: http://www.geekpedia.com/tutorial198_Creating-a-Rich-Text-Editor-using-JavaScript.html


Before I forget, I also decided to make a tiny editor myself after your question with an API etc. (but release date is about two weeks from now ;) ) but before I started my own, I created a tutorial on how to do make a tiny editor (aka a rich text editor). You might want to check it out:
