尝试以下代码，

var app = angular.module("app", []);

app.controller("InputController", function($scope) {
    $scope.user={"id":1};
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<body ng-app="app" ng-controller="InputController">
      <input type="text" value="{{user.id}}" class="form-control" id="pid" ng-model="user.id" readonly />
    </body>

我想用值属性的值设置模型的值
