Can anyone help me how to remove the last entered character from textfield.

For example I have to allow only integers in the textfield.

so if we enter any hyphen(-) not as first character it should remove.

How can I achieve this using jquery?

I can do it using keypress where i can restrict keycode based on numbers available. But I want to find out the last entered character using keyup.

If you actually just want integers I can recommend using `type="number"` on your input. – smoksnes Jul 21 '16 at 06:58
@smoksnes the number field also allows `+`, `-`, `.` and `e` – Rory McCrossan Jul 21 '16 at 07:00
@RoryMcCrossan, yes. That's true, and the OP didn't want to use `-`. – smoksnes Jul 21 '16 at 07:01
I know all those things but I just want to know is there any way to find out which character is the latest entry in the textfield at what charset – user1268130 Jul 21 '16 at 07:02
Just wrote half an answer, and then the post just closed? Why was that? (I'm kinda new to StackOverflow, so just trying to figure it out...) – Whothehellisthat Jul 21 '16 at 07:03
@user1268130: You can use `textbox.value[textbox.value.length - 1]` to get the last character in the textbox. – Whothehellisthat Jul 21 '16 at 07:04
That provides the last value even though if we enter any character at first. In that situation how can I get the latest entry – user1268130 Jul 21 '16 at 07:06
