Strings have many properties. For example when they click on backspace you can use the left function to take everything but the last character. There are many ways this can be done.

Solution 2

you can try something like this in the javascript.
it will act like a backspace.
the below line will remove the last char of the textbox.

JavaScript

textbox.value =  textboxvalue.substring(0,textboxvalue.length-1);

note: pls handle exceptions :)
