允许保留 2 位小数 - Allow 2 decimal places in
问题:
I have a <input type="number">
and I want to restrict the input of the users to purely numbers or numbers with decimals up to 2 decimal places.我有一个<input type="number">
并且我想将用户的输入限制为纯数字或小数点后最多 2 位小数的数字。
Basically, I am asking for a price input.基本上,我要求输入价格。
I wanted to avoid doing regex.我想避免做正则表达式。 Is there a way to do it?有没有办法做到这一点?
<input type="number" required name="price" min="0" value="0" step="any">
