Stop the user from pressing a key

[heavensgate15]

Is there a way in javascript where in the user cannot press further on keyboard if a certain number of characters were pressed..?

For example, in a textarea, if the user typed 250 characters already, and if he attempted to type further, it will not show on the textarea...:confused:
