[JavaScript] onkeypress and onchange event

Source: Internet
Author: User
  • Onkeypress occurs when a keyboard key is pressed or held down
  • Onchange occurs when the content of a field changes

OK, let's go further. If you want to validate the character number limitation of one textarea control, which one you shoshould choose?

I told you that the onchange is better. Because if you use Copy text from somewhere to this control, the onkeypress will not be converted Ted; while, the onchange will be worked well.

And now, I think you can distinguish the two JavaScript events easily.
