[jQuery] Text Box readonly

[jQuery] Text Box readonly


I am writing a small script at the moment that requires a text box to
be readonly for a period of time and once that time is up then I want
to remove the readonly attribute, is there a way to allow this to
happen after a duration of time has passed or after an event has
happened.
jQuery(document).ready(function($) {
$("input").attr("readonly", "readonly");
$("input").removeAttr("readonly");
});
not sure how to delay the removeAttr event for a duration of time as I
can only find a delay in the effects area.
Thankyou for your help
