<input type="number"> not working in IE10
提问by Richard Anthony Hein
Although I'm pretty sure this was working yesterday or the day before, <input type="number" min="0" max="50" step="10" value="0" />, for example, no longer works in IE10. I've tested my browser with http://ie.microsoft.com/testdrive/HTML5/Forms/Default.htmland it's just not working anymore. Anyone else having this issue? Or, did it never work?
虽然我很确定这在昨天或前一天有效<input type="number" min="0" max="50" step="10" value="0" />，例如，在 IE10 中不再有效。我已经用http://ie.microsoft.com/testdrive/HTML5/Forms/Default.html测试了我的浏览器，但它不再工作了。还有谁有相同的问题吗？或者，它从未奏效？

IE doesn't have support for input type="number" but you can use jQueryUI Spinner widget. It is very simple to use and it has many API's that friendly for developers.
IE 不支持 input type="number" 但您可以使用 jQueryUI Spinner 小部件。它使用起来非常简单，并且有许多对开发人员友好的 API。

Internet Explorer 10 supports the number input. This is evident from a cursory examination of their documentation, as well as an attempt to use it within the browser itself. For example, attempting to place a letter in a number input will result in the value being cleared when the control loses focus.
Internet Explorer 10 支持数字输入。从粗略检查他们的文档以及在浏览器本身中使用它的尝试中可以明显看出这一点。例如，尝试在数字输入中放置一个字母将导致该值在控件失去焦点时被清除。
You can also feature-detect support for number by programmatically doing the aforementioned test:
您还可以通过以编程方式执行上述测试来检测对数字的支持：
// Create the element
var element = document.createElement( "input" );
// Give it the number property and invalid contents
element.type = "number";
element.value = "qwerty";
// Value should be empty
alert( element.value ? "Not Supported" : "Supported" );

It may very well be that you're equating progressively-enhanced UI (the spinners) with support for the control itself. I've seen this confuse a few people already. Somebrowsers augment supplement the number input with additional controls, but this is not (to my knowledge) a requirement for support.
很可能您将逐步增强的 UI（微调器）等同于对控件本身的支持。我已经看到这让一些人感到困惑。一些浏览器通过额外的控件来增加对数字输入的补充，但这不是（据我所知）支持的要求。

Just verified on our Windows 8 test machine, there is no number spinner on their test drive site in IE10.
刚刚在我们的 Windows 8 测试机上验证，在他们的 IE10 测试驱动站点上没有数字微调器。

Microsoft has validation bugs/errors still with input type=number, this is in IE11 as well.
Microsoft 在 input type=number 的情况下仍然存在验证错误/错误，这也在 IE11 中。
Just as I was starting to like Internet Explorer again... Hopefully they can fix this in IE12, fingers crossed
就像我再次开始喜欢 Internet Explorer 一样......希望他们能在 IE12 中解决这个问题，手指交叉

这是我开发的解决方案，我认为它工作得很好，希望它可以帮助某人
function handleKeyPress(e) {
let newValue = e.target.value + e.key;
if (
// It is not a number nor a control key?
isNaN(newValue) &&
e.which != 8 && // backspace
e.which != 17 && // ctrl
newValue[0] != '-' || // minus
// It is not a negative value?
newValue[0] == '-' &&
isNaN(newValue.slice(1)))
e.preventDefault(); // Then don't write it!
}Insert a number:
<input onKeyPress="handleKeyPress(event)"/>
