插件主要代码:
//vdt.jsconst VDT = { messages: { required: "这是必填字段", remote: "请修正此字段", email: "请输入有效的电子邮件地址", url: "请输入有效的网址", date: "请输入有效的日期", dateISO: "请输入有效的日期 (YYYY-MM-DD)", number: "请输入有效的数字", digits: "只能输入数字", creditcard: "请输入有效的信用卡号码", equalTo: "你的输入不相同", extension: "请输入有效的后缀", minlength: "输入字数过短", maxlength: "输入字数过长", mphone: "请输入正确的手机号格式", tphone: "请输入正确的电话格式", postal: "请输入正确的邮编格式"
}, required: function (value, param) { return value != undefined ? (value.toString().length > 0) : false;
}, email: function (value) { return /^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/.test(value);
}, url: function (value) { return /^(?:(?:(?:https?|ftp):)?\/\/)(?:\S+(?::\S*)?@)?(?:(?!(?:10|127)(?:\.\d{1,3}){3})(?!(?:169\.254|192\.168)(?:\.\d{1,3}){2})(?!172\.(?:1[6-9]|2\d|3[0-1])(?:\.\d{1,3}){2})(?:[1-9]\d?|1\d\d|2[01]\d|22[0-3])(?:\.(?:1?\d{1,2}|2[0-4]\d|25[0-5])){2}(?:\.(?:[1-9]\d?|1\d\d|2[0-4]\d|25[0-4]))|(?:(?:[a-z\u00a1-\uffff0-9]-*)*[a-z\u00a1-\uffff0-9]+)(?:\.(?:[a-z\u00a1-\uffff0-9]-*)*[a-z\u00a1-\uffff0-9]+)*(?:\.(?:[a-z\u00a1-\uffff]{2,})).?)(?::\d{2,5})?(?:[/?#]\S*)?$/i.test(value);
}, date: function (value) { return !/Invalid|NaN/.test(new Date(value).toString());
}, dateISO: function (value) { return /^\d{4}[\/\-](0?[1-9]|1[012])[\/\-](0?[1-9]|[12][0-9]|3[01])$/.test(value);
}, number: function (value) { return /^(?:-?\d+|-?\d{1,3}(?:,\d{3})+)?(?:\.\d+)?$/.test(value);
}, digits: function (value) { return /^\d+$/.test(value);
}, isarr: function (o) { return Object.prototype.toString.call(o) == '[object Array]';
}, minlength: function (value, param) { return value.length >= param;
}, maxlength: function (value, param) { return value.length <= param;
}, rangelength: function (value, param) { var length = $.isArray(value) ? value.length : this.getLength(value); return (length >= param[0] && length <= param[1]);
}, min: function (value, param) { return value >= param;
}, max: function (value, param) { return value <= param;
}, range: function (value, param) { return (value >= param[0] && value <= param[1]);
}, equalTo: function (value, param) { return value === param;
}, mphone: function (value) { return /^1[3|4|5|8][0-9]\d{4,8}$/.test(value);
}, tphone: function (value) { return /^[+]{0,1}(\d){1,3}[ ]?([-]?((\d)|[ ]){1,12})+$/.test(value);
}, postal: function (value) { return /^[a-zA-Z0-9 ]{3,12}$/g.test(value);
}, vdata: function (value, config) {//返回正确错误对象 提示 与结果
for (var fun in config) { if (typeof this[fun] == "function" && (!(config[fun].param == undefined ? this[fun](value) : this[fun](value, config[fun].param)))) { if (typeof config[fun] == "object") { return { msg: config[fun].msg ? config[fun].msg : this.messages[fun], result: false };
} else { return { msg: typeof config[fun] == "string" ? config[fun] : this.messages[fun], result: false };
}
} else if (typeof config[fun] == "function") { var tmpr = config[fun](value); if (tmpr != "" && tmpr != undefined && tmpr != false) { return { msg: tmpr, result: false }
}
}
} return { msg: "", result: true };
}
};使用(点击查看效果):
