Text Input Right to Left
How would one accomplish a text input that works similar to RTL input. For instance, if the text box starts with value of "0.00"; if the user hits 5 then the value is "0.05" and then if the user enter 23 then the value becomes "5.23". Any suggestions?

That''s not a RTL input, it''s just right-aligned :) (You still
read the
values from LTR)
To format the numbers, I''d add a method in String.prototype
String.prototype.padAsFloat = function(precision) { // UNTESTED!
var precision = precision || 2, number = parseInt(this.replace(/\./,
"")).toPaddedString(precision + 1), decimal, integer;
decimal = number.substring(number.length - precision);
integer = number.length > precision ? number.substring(0,
number.length - precision) : "0";
return integer + "." + decimal;
}
Then you can capture the onkeydown event, get the pressed key, append
it to the current value, call padAsFloat on the string and then set
the input''s value to the result. Or something along those lines :)
HTH,
