HTML5 input number min max not working with required
提问by user1330974
I would like to force the user to type their age. I also would like to make sure they only enter between 18-99. Is that possible with HTML5attributes like required, pattern, minand max? Seems like it is not working
我想强制用户输入他们的年龄。我还想确保他们只进入 18-99 之间。这是可能与HTML5属性，如required，pattern，min和max？似乎它不起作用
<form>
<input type="number" name="Q2age" id="Q2age" size="10" min="18" max="99" pattern="[1-8][0-9]" required>
<button type="submit" class="button" id="test">Submit</button>
</form>
Am I doing something wrong here? I use Firefox 22.0 on Ubuntu 12.0.4LTS (tested on Chrome as well, but doesn't work.) Thank you for your help.
我在这里做错了吗？我在 Ubuntu 12.0.4LTS 上使用 Firefox 22.0（也在 Chrome 上测试过，但不起作用。）谢谢你的帮助。

This is the expected behaviour because FF21 doesnt supports min,max attribute...
这是预期的行为，因为 FF21 不支持 min,max 属性...
