How can I enter only numbers in TextBox using JavaScript without disable right click ?

Question

I want to allow numbers only to be allowed for a textbox and I already do it onkeydown event by allow only numbers and prevent ctrl+V but I have two problems :

1. if I make right click then paste so any char can be entered and I want a solution without disable right click by oncontextmenu="return false;"

2. if I drag and drop any text it will be entered

Is there any solution that can work in all browsers without problem ?

Answer 1

Just filter out the non numeric chars in the onchange event of your textbox and set it back to the textbox.

Answer 2

You can use onpaste event. You will be able to catch whenever something is pasted.
You can refer to Andy's answer regarding onpaste event.
