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

you can use the maxLength attribute for that, try

 $(".test").keyup(function (event) {
        var last = $(this).val()[$(this).val().length - 1];
        if (last == '.') {
            $(".test").attr("maxlength", $(this).val().length+2);
         }
    });
