jquery验证只有数字

jquery validation only digits(jquery验证只有数字)

问题描述

我有 jquery.validate.js 插件，它对我来说很好用.

I am having the jquery.validate.js plugin and it is working fine for me.

我的问题是:

我有一个文本框，这个文本框是强制性的，应该只接受数字.

I am having a textbox and this textbox is mandatory and should only accept digits.

在js中，我可以看到有数字验证，问题是我不知道如何使用它.

In the js, I can see that there is validation for the digits and the problem is that I do not know how to use it.

我只知道如何通过将文本框字段放入<class="required">

I only knew how to make the field required by putting in the textbox field <class="required">

那么，我怎样才能再添加一个验证条件来只接受数字.

So, how can I add one more validation criteria to accept only digits.

感谢

检查一下添加

$("#myform").validate({
  rules: {
    amount: {
