A simple example of this is opacity: el.style.opacity = 0.3; //works fine el.style.opacity = 1.3877787807814457e-16; // fails -- Webkit invalidates the style altogether (yielding opacity == 1.0) This will also fail for values specified in octal or hexadecimal, as they are treated as strings. This does work as expected in Firefox 1.5 (converting the numbers), however. 33785 1 6681 bfults 2006-02-23 10:52:05 -0800 Created attachment 6681 Test case: simple fader. 40843 2 8069 ap 2006-05-02 05:32:55 -0700 Created attachment 8069 reduced test case 40844 3 ap 2006-05-02 05:39:09 -0700 Trying to set the opacity to an invalid value such as 1e-16 has no effect in Firefox, but resets it in Safari. I'm not quite sure about what constitutes an invalid value, but the issue doesn't look like related to strings to me. 40847 4 bfults 2006-05-02 06:01:50 -0700 The so-called "invalid value" is a valid Number literal in JS. I suppose whether it's an "invalid value" depends entirely on whether the DOM as bound to by JS is supposed to only accept numbers in a specific format (decimal) or if any JS Number should be converted to a value suitable for DOM assignment. 36649 5 ap 2007-01-06 16:06:04 -0800 (In reply to comment #4) > The so-called "invalid value" is a valid Number literal in JS. That's correct, but then it's converted back to a string and passed to CSS parser, which doesn't understand scientific notation. The problem with handling invalid values has been recently fixed, see bug 7296. The test case now works just like it does in Firefox. We just don't log an error to the console yet, unlike Firefox. 6681 2006-02-23 10:52:05 -0800 2006-02-23 10:52:05 -0800 Test case: simple fader. js-fader.html text/html 1783 bfults PCFET0NUWVBFIGh0bWwgUFVCTElDICItLy9XM0MvL0RURCBYSFRNTCAxLjAgU3RyaWN0Ly9FTiIg CgkiaHR0cDovL3d3dy53My5vcmcvVFIveGh0bWwxL0RURC94aHRtbDEtc3RyaWN0LmR0ZCI+Cjxo dG1sIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8xOTk5L3hodG1sIiB4bWw6bGFuZz0iZW4iIGxh bmc9ImVuIj4KCTxoZWFkPgoJCTxtZXRhIGh0dHAtZXF1aXY9IkNvbnRlbnQtdHlwZSIgY29udGVu dD0idGV4dC9odG1sOyBjaGFyc2V0PXV0Zi04IiAvPgoJCTx0aXRsZT48L3RpdGxlPgoJCTxzdHls ZSB0eXBlPSJ0ZXh0L2NzcyI+CgkJI2JveCB7IHdpZHRoOiAzMDBweDsgaGVpZ2h0OiAyMDBweDsg YmFja2dyb3VuZC1jb2xvcjogcmVkIH0KCQkjYm94LmJsdWUgeyBiYWNrZ3JvdW5kLWNvbG9yOiBi bHVlIH0KCQk8L3N0eWxlPgoJCTxzY3JpcHQgdHlwZT0idGV4dC9qYXZhc2NyaXB0Ij4KCQlmdW5j dGlvbiBwcmludChzKQoJCXsKCQkJZG9jdW1lbnQuZ2V0RWxlbWVudEJ5SWQoIm91dCIpLmFwcGVu ZENoaWxkKGRvY3VtZW50LmNyZWF0ZVRleHROb2RlKHMrIlxuIikpOwoJCX0KCQlmYWRlVHJhbnNp dGlvbiA9IGZ1bmN0aW9uKGVsLCBzQ2xhc3NUbywgblNlY29uZHMpCgkJewoJCQllbC5zdHlsZS5w b3NpdGlvbiA9ICJyZWxhdGl2ZSI7CgkJCXZhciBuU3RlcE9wYWNpdHkgPSAwLjE7CgkJCXZhciBu U3RlcFRpbWUgPSAoblNlY29uZHMgLyAoMiAvIG5TdGVwT3BhY2l0eSkpICogMTAwMDsKCQkJdmFy IG5PcGFjaXR5ID0gMS4wOwoJCQl2YXIgbkZhY3RvciA9IC0xOwoJCQllbC5zdHlsZS5maWx0ZXI9 ImFscGhhKG9wYWNpdHk9MTAwKSI7CgkJCXZhciBpZEludGVydmFsID0gd2luZG93LnNldEludGVy dmFsKGZ1bmN0aW9uKCkKCQkJewoJCQkJLy8gY2hhbmdlIHRoZSBvcGFjaXR5IGJ5IHRoZSBzdGVw IHZhbHVlIGFuZCBhcHBseSB0byB0aGUgZWxlbWVudAoJCQkJbk9wYWNpdHkgKz0gKG5TdGVwT3Bh Y2l0eSAqIG5GYWN0b3IpLnRvRml4ZWQoMykqMS4wOwoJCQkJc2V0T3BhY2l0eShlbCwgbk9wYWNp dHkpOwoJCQkJCgkJCQlwcmludChuT3BhY2l0eSk7CgoJCQkJLy8gaWYgd2UndmUgcmVhY2hlZCAw LCByZXZlcnNlIHRoZSBmYWRlIGFuZCBhZGQgdGhlIGNsYXNzCgkJCQlpZiAobk9wYWNpdHkgPD0g MCkKCQkJCXsKCQkJCQluRmFjdG9yICo9IC0xOwoJCQkJCWVsLmNsYXNzTmFtZSArPSAnICcrIHND bGFzc1RvOwoJCQkJfQoKCQkJCS8vIGlmIHdlJ3JlIGJhY2sgYXQgZnVsbCBvcGFjaXR5LCBzdG9w IHRoZSBmYWRlCgkJCQlpZiAobk9wYWNpdHkgPj0gMS4wKSB3aW5kb3cuY2xlYXJJbnRlcnZhbChp ZEludGVydmFsKTsKCQkJfSwgblN0ZXBUaW1lKTsKCQl9CgkJc2V0T3BhY2l0eSA9IGZ1bmN0aW9u KGVsLCBuT3BhY2l0eSkKCQl7CgkJCWlmIChlbCkKCQkJewoJCQkJZWwuc3R5bGUub3BhY2l0eSA9 IG5PcGFjaXR5OwoJCQkJaWYgKGVsLmZpbHRlcnMpCgkJCQl7CgkJCQkJZWwuZmlsdGVycy5hbHBo YS5vcGFjaXR5ID0gTWF0aC5yb3VuZChuT3BhY2l0eSAqIDEwMCk7CgkJCQl9CgkJCX0KCQl9CgkJ ZG9mYWRlID0gZnVuY3Rpb24oKQoJCXsKCQkJZmFkZVRyYW5zaXRpb24oZG9jdW1lbnQuZ2V0RWxl bWVudEJ5SWQoImJveCIpLCAiYmx1ZSIsIDUuMCk7CgkJfQoJCTwvc2NyaXB0PgoJPC9oZWFkPgoJ PGJvZHk+Cgk8ZGl2PjxidXR0b24gb25jbGljaz0iZG9mYWRlKCkiPkZhZGUhPC9idXR0b24+PC9k aXY+Cgk8ZGl2IGlkPSJib3giPjwvZGl2PgoJPHByZSBpZD0ib3V0Ij5vcGFjaXR5OjwvcHJlPgoJ PC9ib2R5Pgo8L2h0bWw+Cg== 8069 2006-05-02 05:32:55 -0700 2006-05-02 05:32:55 -0700 reduced test case js-fader.html text/html 553 ap PCFET0NUWVBFIGh0bWwgUFVCTElDICItLy9XM0MvL0RURCBYSFRNTCAxLjAgU3RyaWN0Ly9FTiIg CgkiaHR0cDovL3d3dy53My5vcmcvVFIveGh0bWwxL0RURC94aHRtbDEtc3RyaWN0LmR0ZCI+Cjxo dG1sPgoJPGhlYWQ+CgkJPHN0eWxlIHR5cGU9InRleHQvY3NzIj4KCQkjYm94IHsgd2lkdGg6IDMw MHB4OyBoZWlnaHQ6IDIwMHB4OyBiYWNrZ3JvdW5kLWNvbG9yOiByZWQgfQoJCTwvc3R5bGU+CgkJ PHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPgoJCWRvZmFkZSA9IGZ1bmN0aW9uKCkKCQl7 CgkJCXZhciBlbCA9IGRvY3VtZW50LmdldEVsZW1lbnRCeUlkKCJib3giKTsKCQkJZWwuc3R5bGUu cG9zaXRpb24gPSAicmVsYXRpdmUiOwoJCQllbC5zdHlsZS5vcGFjaXR5ID0gMC4xOwoJCQllbC5z dHlsZS5vcGFjaXR5ID0gMWUtMTY7CgkJfQoJCTwvc2NyaXB0PgoJPC9oZWFkPgoJPGJvZHk+Cgk8 ZGl2PjxidXR0b24gb25jbGljaz0iZG9mYWRlKCkiPkZhZGUgdG8gMTAlPC9idXR0b24+PC9kaXY+ Cgk8ZGl2IGlkPSJib3giPjwvZGl2PgoJPC9ib2R5Pgo8L2h0bWw+Cg==
