jQuery:表单验证插件-验证特定的字符串? [英] JQuery: Form Validation plugin - validate specific string?

问题描述

我有一个使用此插件的表单:

I have a form that uses this plugin:

http://bassistance.de/jquery-plugins/jquery-plugin-validation/

效果很好-但我无法弄清楚如何通过输入到文本字段中的特定字符串进行验证.例如，我要创建一个仅在用户输入为"foo"时才验证字段的规则.

Works great - but I cant figure how to validate by a specific string in-putted into a text field. For example, I want to create a rule that only validates a field if the users input is "foo".

此处提供文档 http://docs.jquery.com/Plugins/Validation#API_Documentation

但是他们似乎都不是我想要的那个.有人知道解决这个问题的方法吗?

But none of them seem to be the one I want. Does anyone know a way to get round this?

谢谢！

推荐答案

简单的一个...

$.validator.addMethod("equals", function(value, element, string) {
    return value === string;
}, $.validator.format("Please enter '{0}'"));
$("#form").validate({
    rules: {            
        name: {
            required: true,
            equals: "foo"
        }
    }
});

根据您的要求更新

$.validator.addMethod("equals", function(value, element, string) {
    return $.inArray(value, string) !== -1;
}, $.validator.format("Please enter '{0}'"));
$("#form").validate({
    rules: {            
        name: {
            required: true,
            equals: ["foo", "bar", 'blah"]
        }
    },
    messages: {
        name: "Please enter either '{0}' or '{1}' or '{2}'"
    }
});
