我正在使用 HTML5、CSS3 和 Jquery 为 iPad 开发调查表。根据要求，在邮政编码中立即显示数字键盘而不是字符键盘，然后必须选择按钮切换数字键盘。所以在javascript中，有可能做到吗？如果是，怎么做？请给出一些建议。感谢所有的先进。

I haven't tried it on my iPad to see which keyboard is displayed but if there is a way I'm sure it would be the HTML 5 Input Type. This is what the new input type is supposed to do. I would be mildly surprised if the iPad didn't behave as expected when you have the correct type set.
我还没有在 iPad 上尝试过查看显示哪个键盘，但如果有办法我确定它是HTML 5 Input Type。这就是新的输入类型应该做的。如果在您设置正确的字体时 iPad 没有按预期运行，我会感到有点惊讶。
Try this code:
<input type="number" name="mynumber"...>
试试这个代码：
<input type="number" name="mynumber"...>
Update:It does work on my iPhone (iOS 5.0.1). It doesn't pull up the "numeric only" keyboard like you get when you are unlocking the phone, but it does pull up the "numbers and symbols" keyboard like you get when you click the "123" button on the normal keyboard.
更新：它适用于我的 iPhone (iOS 5.0.1)。它不会像解锁手机时那样拉起“仅数字”键盘，但会像单击普通键盘上的“123”按钮时那样拉起“数字和符号”键盘。
Update:Type changed from 'numeric' to 'number'
更新：类型从“数字”更改为“数字”
