Bootstrap input type="number" doesn't do anythying
提问by ed209
I have a form that I need to force users to input numbers into. However, the following doesn't work
我有一个表单，我需要强制用户输入数字。但是，以下不起作用
<input type="number" name="price[<?=$custom_item->quote_items_id?>]" value="" placeholder="$">
I can hit submit no matter what I type in. Is this a bootstrap thing? I thought it was a html5 thing that couldn't be overridden. If I change it to email it will force an email. Any suggestions?
无论我输入什么，我都可以点击提交。这是引导程序吗？我认为这是一个无法覆盖的 html5 东西。如果我将其更改为电子邮件，它将强制发送电子邮件。有什么建议？
