<body ng-app="myApp" ng-controller="MoinController">
<style>

border: 1px solid red!important;

<form name="signUpForm" ng-submit="submitForm()">
<div class="form-group">
<label>用户名：</label>
<input class="form-control" name="username" ng-model="username" ng-minlength="4" ng-maxlength="10" ng-class="{‘error‘:signUpForm.username.$invalid &&
signUpForm.username.$touched }" required/>
</div>
</form>
</body>

console.log(‘表单提交了‘)
}
})
</script>
表单验证 ng-minlength:最小长度 ng-maxlength:最大长度 ng-class:根据条件添加class ng-submit:表单提交 该示例意义为：输入验证，当输入时不满足最少为4最多为10的字符时，自动给input添加error类，首次进入页面不生效
