jquery-validate 身份证验证

今天要用到身份证号码验证，于是上网搜了下，发现了个超级好用的身份证号验证，我把自己的身份证号输入验证后显示正确，我改了一个号码，然后就不正确了，很细致，今天收藏了，好东西，留着以后用。

身份证号码验证

// 验证身份证号码 
jQuery.validator.addMethod("isIdCardNo", function(value, element) { 
    return this.optional(element) || idCardNoUtil.checkIdCardNo(value);     
}, "请正确输入您的身份证号码");
