Validator


Build Status

Validator 是一个牛逼的表单校验组件。

Validator 继承了 widget,可使用其中包括 baseclasseventsattributeaspect 的属性和方法。

Feature List

  • HTML5 form API。

  • data-attribute API。

  • 异步校验。

  • 校验规则的组合,与、或、非。

  • 校验规则的动态绑定与解绑。

  • (TODO)关联性校验/级联校验。例如当满足一个条件时校验某种规则,满足另外的条件校验其他规则。

How to Use

提供两种方式调用:

  • DOM。利用 html5 form API 和 data-attribute 在 DOM 中完成调用。
  • JS API。在 javascript 代码中完成 validator 配置和调用。

DOM 调用

HTML

    <form data-widget="validator" class="ui-form">
        <div class="ui-form-item">
            <label for="username" class="ui-label"><span class="ui-form-required">*</span>用户名:</label>
            <input id="username" name="username" class="ui-input" required type="email" minlength="1" maxlength="20" />
            <div class="ui-form-explain">用户名为电子邮箱。</div>
        </div>

        <div class="ui-form-item ui-form-item-error">
            <label for="password" class="ui-label"><span class="ui-form-required">*</span>密码:</label>
            <input id="password" name="password" type="password" class="ui-input" minlength="5" />
            <div class="ui-form-explain">密码的长度必须大于或等于5。</div>
        </div>

        <div class="ui-form-item">
            <label for="password-confirmation" class="ui-label"><span class="ui-form-required">*</span>重复输入密码:</label>
            <input id="password-confirmation" name="password-confirmation" type="password" class="ui-input" data-rule="confirmation{target: '#password'}" />
        </div>

        <div class="ui-form-item">
            <span class="ui-button-morange ui-button"><input class="ui-button-text" value="确定" type="submit"></span>
        </div>
    </form>

JS

    seajs.use(['widget', '$'], function(Widget, $) {
        $(function() {
            // 初始化所有使用`data-widget`指定的组件。
            Widget.autoRenderAll();
        });
    });
