Solution 1

The reason is that BACKSPACE has its default behavior too - deleting one character...
If you want to stop the default behavior you have to stop the bubbling (propagation) of the event...
As you use jQuery you can benefit from event.stopPropagation()[^]

JavaScript

if(e.which==8)
{
  $("#txtsid").focus()

  e.stopPropagation();
}

Solution 2

You can try to override the default function of the event, by using this code,

JavaScript

event.preventDefault();

.. write this line inside the very first line of the event handler, using which will prevent all of the default functions that it can perform and the remaining code will execute as it should.
