客户端数据验证框架

网页程序自然离不开数据的更新与保存,更新与保存前的数据验证我们称之为 客户端数据验证 ,本框架提供了一种非常简单的客户端数据验证方法

通过简单的 html 样式名称或者属性名框架与相关验证方法进行关联,控件失去焦点或者点击验证按钮时触发客户端验证逻辑

在线演示

单页面演示:http://longbowenterprise.gitee.io/slidercaptcha/

快速开始

组件依赖 jQuery bootstrap Validate

CSS

<link href="./lib/twitter-bootstrap/css/bootstrap.min.css">

将引入样式表的 <link> 标签复制并粘贴到 <head> 中,并放在所有其他样式表之前。

JS

<script src="./lib/jquery/jquery.min.js"></script>
<script src="./lib/twitter-bootstrap/js/bootstrap.bundle.min.js"></script>
<script src="./lib/validate/jquery.validate.js"></script>
<script src="./lib/validate/localization/messages_zh.min.js"></script>
<script src="./dist/longbow.validate.js"></script>

将引入脚本的 <script> 标签复制并粘贴到 <body> 最后面。

用法

要验证的网页代码示例

<div class="card">
    <div class="card-header">网站名称设置</div>
    <div class="card-body" data-toggle="LgbValidate" data-valid-button="[data-method='title']">
        <div class="form-group">
            <div class="input-group">
                <input type="text" class="form-control" id="sysName" placeholder="请输入网站标题,50字以内" value="网站标题" maxlength="50" data-valid="true" />
                <div class="input-group-append">
                    <button class="btn btn-secondary" type="button" data-method="title">保存</button>
                </div>
            </div>
        </div>
    </div>
</div>
  1. 设置验证作用域 data-toggle="LgbValidate"
  2. 设置验证按钮 data-valid-button="[data-method='title']"
  3. 设置需要验证的控件 data-valid="true"
  4. 设置验证规则 maxlength="50" 支持 css 样式与 html 属性

效果图

内置验证规则

  • 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"
  • maxlength: "最多可以输入 {0} 个字符"
  • minlength: "最少要输入 {0} 个字符"
  • rangelength: "请输入长度在 {0} 到 {1} 之间的字符串"
  • range: "请输入范围在 {0} 到 {1} 之间的数值"
  • step: "请输入 {0} 的整数倍值"
  • max: "请输入不大于 {0} 的数值"
  • min: "请输入不小于 {0} 的数值"
  • ip: "请填写正确的IP地址"
  • radioGroup: "请选择一个选项"
  • checkGroup: "请选择一个选项"
  • userName: "登录名称不可以包含非法字符"
  • greaterThan: "数值必须大于 {0}"
  • lessThan: "数值必须小于 {0}"

扩展验证规则

$.validator.addMethod("userName", function (value, element) {
    return this.optional(element) || /^[a-zA-Z0-9_@.]*$/.test(value);
}, "登录名称不可以包含非法字符");

通过静态方法 $.validator.addMethod 方法增加自己的验证规则

Api

获得某个控件的验证组件框架实例 $('#Id').lgbValidator()

获得某个验证域内所有组件是否合规 $('#Id').lgbValid() 返回 true 时表示合规,返回 false 时表示不合规
