style function fails to check for parseFloat(value) == NaN causing IE6 error

[crispi]

This error only occurs in IE6 - other browsers appear to tolerate it. When the style function is called and a null or non-float value is passed for name = "height", IE6 errors out.

Changing the code to this appears to fix it:

if ( (name === "width"

name === "height") && (parseFloat(value) < 0

isNaN(parseFloat(value)))) {

value = undefined;

}

Can you reopen with a test case? I am not sure why it would be necessary to check for NaN. This works in IE6:

$("div").width("14px");
$("div").css("width", "auto");

These do not but they are passing invalid input to jQuery:

$("div").width("sorry");  // not a number
$("div").css("width", "0.2km");  // invalid units
