angularJS 中的表单验证
1.表单中常用的验证操作
$dirty 表单有填写记录
$valid 字段内容合法的
$invalid 字段内容是非法的
$pristine 表单没有填写记录
$error 表单验证不通过的错误信息
2.验证时须给表单及需要验证的input设置name属性：
给form及input设置name后，会将form表单信息默认绑定到$scope作用域中
故可以使用formName.inputName.$验证操作得到验证结果：
例如：formName.inputName.$dirty="true" 表单被填写过
formName.inputName.$error.required="true" 表单必填但未填
error支持的验证有：required/minlength/pattern/email/date/url等
3.为避免冲突，例如使用type="email"时，H5也会进行验证操作。如果只想使用angularJS验证，可以使用
<form novalidate></form>属性，禁用H5自带验证功能
