三、默认的提示 

messages: { required: "This field is required.", remote: "Please fix this field.", email: "Please enter a valid email address.", url: "Please enter a valid URL.", date: "Please enter a valid date.", dateISO: "Please enter a valid date (ISO).", dateDE: "Bitte geben Sie ein g眉ltiges Datum ein.", number: "Please enter a valid number.", numberDE: "Bitte geben Sie eine Nummer ein.", digits: "Please enter only digits", creditcard: "Please enter a valid credit card number.", equalTo: "Please enter the same value again.", accept: "Please enter a value with a valid extension.", maxlength: $.validator.format("Please enter no more than {0} characters."), minlength: $.validator.format("Please enter at least {0} characters."), rangelength: $.validator.format("Please enter a value between {0} and {1} characters long."), range: $.validator.format("Please enter a value between {0} and {1}."), max: $.validator.format("Please enter a value less than or equal to {0}."), min: $.validator.format("Please enter a value greater than or equal to {0}.") },

如需要修改,可在js代码中加入: 

jQuery.extend(jQuery.validator.messages, { required: "必选字段", remote: "请修正该字段", email: "请输入正确格式的电子邮件", url: "请输入合法的网址", date: "请输入合法的日期", dateISO: "请输入合法的日期 (ISO).", number: "请输入合法的数字", digits: "只能输入整数", creditcard: "请输入合法的信用卡号", equalTo: "请再次输入相同的值", accept: "请输入拥有合法后缀名的字符串", maxlength: jQuery.validator.format("请输入一个长度最多是 {0} 的字符串"), minlength: jQuery.validator.format("请输入一个长度最少是 {0} 的字符串"), rangelength: jQuery.validator.format("请输入一个长度介于 {0} 和 {1} 之间的字符串"), range: jQuery.validator.format("请输入一个介于 {0} 和 {1} 之间的值"), max: jQuery.validator.format("请输入一个最大为 {0} 的值"), min: jQuery.validator.format("请输入一个最小为 {0} 的值") });
