What would be the easiest way to make a number textfield accepting a leading plus?
It throws an “Alert input error” if the number starts with a plus (e.g. “+123” for 123).
I tried to remove the “+” by using a text change listener, but it takes a little while to fire while the number validation jumps in immediately when lost focus.
I use an electronic scale (with a keyboard emulation driver) to input values in some textfields and unfortunately the leading plus sign cannot be disabled.
