允許保留 2 位小數 - Allow 2 decimal places in
問題:
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.我有一個<input type="number">
並且我想將用户的輸入限制為純數字或小數點後最多 2 位小數的數字。
Basically, I am asking for a price input.基本上,我要求輸入價格。
I wanted to avoid doing regex.我想避免做正則表達式。 Is there a way to do it?有沒有辦法做到這一點?
<input type="number" required name="price" min="0" value="0" step="any">
