Allow only 2 decimal points entry to a textbox using javascript or jquery?

Question

I called a class called test for my textbox. When I entered the first value for e.g. the first value as 4., then suddenly the output coming as 4.00

Answer 1

This small change to your code may suffice:

  this.value = this.value.replace (/(\.\d\d)\d+|([\d.]*)[^\d.]/, '$1$2');

Essentially replace the decimal point followed by any number of digits by a decimal point and the first two digits only. Or if a non digit is entered removes it.
