基于angularJS的表单验证练习

<div ng-controller="Aaa">
    <form novalidate name="loginForm">
        <div>
            <label>用户名</label>
            <input type="text" name="nText" ng-model="promptText.name" required ng-pattern="/^[a-zA-Z]+$/" ng-minlength="5" ng-blur="promptText.change(loginForm.nText.$error)"/>
            <span ng-repeat=" pro in promptText.proList | filter:promptText.defaultPro">{{pro.tip}}</span>
        </div>

        <div>
            <label>密码</label>
            <input type="password" name="nPassword" ng-model="promptPassword.name" required ng-pattern="/([a-zA-Z]/w+$)/" ng-minlength="5" ng-blur="promptPassword.change(loginForm.nPassword.$error)"/>
            <span ng-repeat=" pro in promptPassword.proList | filter:promptPassword.defaultPro">{{pro.tip}}</span>
        </div>
    </form>

</div>
