如何在 jQuery.validation 中添加 Not Equal To 规则 [英] How to add a Not Equal To rule in jQuery.validation

问题描述

我想知道如何制作它以便我可以制定一个字段不等于值的规则.就像我有一个名为 'name' 的字段，所以我不想要 'name' = 'Your Name.'

I was wondering how to make it so that I could make a rule where a field is not equal to a value. Like I have a field called 'name' so I don't want 'name' = 'Your Name.'

有人知道如何做到这一点吗?感谢您的帮助.

Does anybody have an idea of how to do this? thanks for any help.

推荐答案

您可以使用自定义方法，如下所示:

You could use a custom method, something like this:

jQuery.validator.addMethod("notEqual", function(value, element, param) {
  return this.optional(element) || value != param;
}, "Please specify a different (non-default) value");

然后像这样使用它:

$("form").validate({
  rules: {
    nameField: { notEqual: "Your Name" }
  }
});

将其添加为这样的规则使其更具扩展性，因此您可以使用它来与其他字段中的默认值进行比较.

Adding it as a rule like this makes it more extensible, so you can use it to compare against the default value in other fields.
