I want to return NaN sometimes (unrestricted double), but the setter needs to just be double. 80540 2 ian 2012-12-22 17:38:13 +0000 Actually for NaN volkmar suggests that setting the value to "" might be more useful. (This is what Gecko does.) Still need to throw for Infinity, though. 80660 3 mounir 2012-12-28 13:06:19 +0000 Gecko/Firefox 20 implements the following behaviour: - |.valueAsNumber = NaN;| will set the value to the empty string (ie. equivalent to |.value = "";|. - |.valueAsNumber = Infinity;| (or -Infinity) will throw without changing the value. Not that for the moment, Gecko doesn't throw TypeError for internal reasons. This will happen later. This change should be soon (max 24 hours) available in a Nightly build. To test it on a Desktop version of Firefox, you have to enable the following pref in about:config: "dom.experimental_forms". The pref is enabled by default on Firefox Mobile.
