regex onBlur input between 1900 and 2050 1

[copeZero]

Hi i was wondering how one would check using regex if an input of a text box is between the numbers of 1900 and 2050

Thanks

[tt]var s="2007"; //the input retrieved as sting
var rx=/^(19[0-9]{2}|20[0-4][0-9]|2050)$/;
if (rx.test(s)) {
//within the range
} else {
//outside of the range
}[/tt]

Thanks, that looked like it took some brilliance for: 20[0-4][0-9]|2050
