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

What about something like this:

$(".test").keyup(function (event) {
if ((pointPos = this.value.indexOf('.')) >= 0)
    $(this).attr("maxLength", pointPos+3);
else
    $(this).removeAttr("maxLength");
});

Here is a working fiddle.
