我正在使用版本0.7.1的角度材料.我正在使用此处描述的自动完成功能：
Autocomplete demo
Autocomplete demo
但是,它似乎不支持验证逻辑,即使它生成textarea：
Autocomplete directive documentation
我想我可以在querySearch函数中添加逻辑来将ng-valid切换为ng-invalid.它是否正确？如果是这种情况,那么我需要一个关于md-autocomplete的句柄,但这很难,因为name属性被删除了.
快速更新,获得Angular Material网站上的解决方案(最新版本1.0.0-),
https://material.angularjs.org/latest/demo/autocomplete.
https://material.angularjs.org/latest/demo/autocomplete.
您会发现现在支持’required’和’ng-messages’.
<div ng-controller="DemoCtrl as ctrl" layout="column" ng-cloak>
