注册表单

初学习angular，用一个简单的用户注册页面来练练手，mark一下，以后需要就直接Ctrl+c了。

<form action="" class="form-horizontal" name="regForm"     ng-controller="regController" 
 ng-submit="submitForm()" novalidate>
    <div class="form-group" ng-class="{'has-success':regForm.username.$valid&&regForm.username.$touched,'has-error':regForm.username.$invalid&&regForm.username.$touched }">
        <label for="" class="col-md-2 control-label">
            用户名
        </label>
        <div class="col-md-9">
            <input type="text" 
            class="form-control" 
            ng-model="user.username" 
            name="username" 
            ng-minlength="4" ng-maxlength="10" 
            placeholder="用户名" 
            required>
            <p class="help-block has-error" ng-show="regForm.username.$error.required&&regForm.username.$touched">用户名不能为空</p>
            <p class="help-block has-error" ng-show="regForm.username.$error.minlength||regForm.username.$error.maxlength">长度为4-10位</p>
        </div>
    </div>
    <div class="form-group" ng-class="{'has-success':regForm.password.$valid&&regForm.password.$touched,'has-error':regForm.password.$invalid&&regForm.password.$touched}">
        <label for="" class="col-md-2 control-label">
            密码
        </label>
        <div class="col-md-9">
            <input type="password" 
            class="form-control" 
            ng-model="user.password" 
            name="password" 
            ng-pattern="/^[A-Za-z]{1}[0-9A-Za-z_]{2,29}$/"
            ng-minlength="4" ng-maxlength="10" 
            placeholder="只能是数字、字母和下划线 " 
            required>
            <p class="help-block has-error" ng-show="regForm.password.$error.required
            &&regForm.password.$touched">密码不能为空</p>
            <!--正则验证-->
            <p class="help-block has-error" ng-show="regForm.password.$error.pattern&&regForm.password.$touched">
            只能是数字、字母和下划线</p>
            <p class="help-block has-error" 
            ng-show="regForm.password.$error.minlength||regForm.password.$error.maxlength">密码为4-10位</p>
        </div>
    </div>
    <div class="form-group" ng-class="{'has-success':regForm.confirmPassword.$valid&&regForm.confirmPassword.$touched,'has-error':(regForm.confirmPassword.$invalid&&regForm.confirmPassword.$touched)||(user.password!=user.confirmPassword&&regForm.confirmPassword.$touched)}">
