HTML5数字输入步骤错误
我正在尝试使用新的 HTML5 数字输入法供用户输入价格。我希望步长为“0.01”。这应该相当简单，我的代码如下所示：
<input type="number" step="0.01" />
好吧，如果您稍微单击箭头，您会得到像 1.1400000000000001 这样的数字或像 1.1 这样的数字对美元来说没有意义。
有谁知道如何使数字字段实际上以 0.01 为步长，并具有一致的有效数字数量？或者如果有人有更优雅的解决方案来允许用户输入价格，我很想听听。
谢谢

Well if you click on the arrows a bit, you'll get numbers like 1.1400000000000001 or numbers like 1.1 which both don't make sense for dollars.
Does anyone know of a way to make the number field actually step by 0.01, and to have a consistent number of significant figures? Or if anyone has a more elegant solution for allowing users to input prices, I would love to hear it.
Thanks

好吧，首先期望 Html 5 的东西在游戏的早期就能按预期工作，并围绕它设计应用程序可能不是一个好主意。
至于解决方案，是的，只需 JavaScript 来递增并向用户提供向上/向下箭头或其他任何内容，并且单击事件可以简单地按您想要的步长值递增/递减值。
Well, first of all expecting Html 5 stuff to work as expected so early in the game and designing applications around that is probably not such a good idea.
As for a solution, yes just to JavaScript to increment and provide the user to up/down arrows or whatever and the click event could simple increment/decrement the value by the step value you desire.
这是预期的 JavaScript 行为，您可以看看这个答案
this is the expected javascript behavior, you can take a look at this answer
