问题描述
以下HTML表单成功使用了jQuery的表单验证，如果留空则在表单字段的右侧显示此字段是必需的，如果输入的字符少于2个则显示请输入至少2个字符。但是，我不想使用cname表单输入字段中的class和minlength属性指定验证元数据，而是使用jQuery的规则API，其中规则在validate函数的主体中指定。在此先感谢：
The following HTML form successfully utilizes jQuery's form validation, displaying "This field is required" to the right of the form field if left blank, and "Please enter at least 2 characters" if fewer than 2 characters were entered. However, instead of the validation metadata being specified using the class and minlength attributes on the "cname" form input field, I'd like to use jQuery's "rules" API instead, where the rules are specified in the body of the validate function. Thanks in advance:
