Как отключить мою кнопку, когда входные данные равны табличным данным
я хочу отключить кнопку, когда текст ввода и таблицы равны
<div ng-app="myApp" ng-controller="myCtrl">
<input type="button" ng-click="add()" value='Add' ng-model="button" >
<table id="tb" >
<tr ng-repeat="x in bimar">
<td><div class="danger" ng-if="x.name==new.name">{{x.error}}</div> </td>
</tr>
</table>
Что я уже пробовал:
<!DOCTYPE html>
<html>
<style>
#tb{padding:10px;background-color:#DAF7A6;}
#tb tr {padding:5px 20px;font-size:20px;background-color:#FFE633;}
.green{background-color:red;}
.yellow{background-color:blue;}
.danger{background-color:red;}
</style>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
نام بیمار <input type="text" name="name" ng-model="new.name" ><br>
تاریخ مراجعه <input type="text" name="date" ng-model="new.date " ><br>
زمان مراجعه <input type="text" name="time" ng-model="new.time" ><br>
<input type="button" ng-click="add()" value='Add' ng-model="button">
<table id="tb" >
<thead>

<tr ng-repeat="x in bimar">

<td ng-class="colorClass" >{{x.date}}</td>
<td ng-class="colorClass">{{x.time}}</td>

<p ng-class="colorClass" >I should be either green or blue!</p>
</div>

var app = angular.module('myApp', []);
