 <body onload='test()'>

<div ng-app="myApp" ng-controller="formCtrl">
    <input type="text" id='aaaa' ng-model="user.firstName"><br>
    <button ng-click="showvalue()">获取</button>
</div>

<script>
    function test(){          
        alert(document.getElementById('aaaa').value);
    }
var app = angular.module('myApp', []);
app.controller('formCtrl', function($scope) {
    $scope.master = {firstName:"John1", lastName:"Doe"};
    $scope.showvalue = function() {
         alert($scope.user.firstName);
    };
    $scope.user = angular.copy($scope.master);
});
</script>
