jQuery validate:如何为正则表达式验证添加规则? [英] jQuery validate: How to add a rule for regular expression validation?

问题描述

我正在使用 jQuery 验证插件.好东西！我想迁移我现有的ASP.NET解决方案以使用jQuery而不是ASP.NET验证器.我缺少正则表达式验证器的替代品.我希望能够做这样的事情:

I am using the jQuery validation plugin. Great stuff! I want to migrate my existing ASP.NET solution to use jQuery instead of the ASP.NET validators. I am missing a replacement for the regular expression validator. I want to be able to do something like this:

$("Textbox").rules("add", { regularExpression: "^[a-zA-Z'.\s]{1,40}$" })

如何添加自定义规则以实现这一目标?

推荐答案

感谢redsquare的回答，我添加了以下方法:

Thanks to the answer of redsquare I added a method like this:

$.validator.addMethod(
        "regex",
        function(value, element, regexp) {
            var re = new RegExp(regexp);
            return this.optional(element) || re.test(value);
        },
        "Please check your input."
);

现在您要做的就是针对任何正则表达式进行验证:

now all you need to do to validate against any regex is this:

$("#Textbox").rules("add", { regex: "^[a-zA-Z'.\\s]{1,40}$" })

此外，看起来还有一个名为extra-methods.js的文件，其中包含方法模式"，使用不带引号的方法创建时，该文件可以是RegExp.

Additionally, it looks like there is a file called additional-methods.js that contains the method "pattern", which can be a RegExp when created using the method without quotes.
