JavaScript get clipboard data on paste event (Cross browser)
问题 How can a web application detect a paste event and retrieve the data to be pasted? I would like to remove HTML content before the text is pasted into a rich text editor. Cleaning the text after being pasted afterwards works, but the problem is that all previous formatting is lost. For example, I can write a sentence in the editor and make it bold, but when I paste new text, all formatting is lost. I want to clean just the text that is pasted, and leave any previous formatting untouched.
