Allow specific characters using onkeyup in input box

I want to allow only a-z, 0-9, and . - _ character using onkeyup in input box:

I use this code: 

<input type="text" onkeyup="this.value=this.value.replace(/[^a-z0-9]/gi, '');" required>

But now I can't write this . - _ character

How to allow this? But restrict only special character like @ #

My value is:

sabbir@ --> only remove @ character,

sabbir_ahmed --> its allow

sabbir.ahmed --> its allow

So I want to remove only special characters like @, #, $ etc.

You just need to add the characters you want to allow to your character class:

<input type="text" onkeyup="this.value=this.value.replace(/[^a-z0-9 ._-]/gi, '');" required>
