如何使用angular js將對象添加到存儲在本地存儲中的數組中？

Question

我正在嘗試使用角度推功能，但是它不起作用。

我每次將新對象替換舊對象時都會將表單值存儲到本地存儲中...

我想將字符串（或對象）添加到數組中。

以下是我的HTML代碼：

<form name="myForm" novalidate>
    <p> Username:<br>
        <input type="text" name="user" ng-model="user.user" required>
        <span ng-show="myForm.user.$pristine"/>
    </p>
        <p>Email:<br>
            <input type="email" name="email" ng-model="user.email" required>
            <span style="color:red" ng-show="myForm.email.$dirty && myForm.email.$invalid">
                <span ng-show="myForm.email.$error.required">Email is required.</span>
                <span ng-show="myForm.email.$error.email">Invalid email address.</span>
            </span>
        </p>

            <p> PhoneNum:<br>
                <input type="number" name="PhoneNum" ng-model="user.PhoneNum" required>
                <span ng-show="myForm.PhoneNum.$pristine"></span>
            </p>
                <p>Address:<br>
                    <input type="text" name="address" ng-model="user.address" required>
                    <span ng-show="myForm.address.$pristine"></span>
                </p>
                    <p>Password:<br>
                        <input type="Password" name="pass" ng-model="user.pass" required>
                        <span ng-show="myForm.pass.$pristine"  />
                    </p>
                        <p>
                            <input type="submit" ng-click="addItem(user)" ng-disabled="myForm.$invalid">
                        </p>

</form>
<pre>user = {{user | json}}</pre>
<table>
{{userdata}}
    <tr>
        <td>user</td>
        <td>Email</td>
        <td>Phone</td>
        <td>Address</td>
        <td>Password</td>
    </tr>
    <tr ng-repeat="x in userArray">
        <td>{{x.user}}</td>
        <td>{{x.email}}</td>
        <td>{{x.PhoneNum}}</td>
        <td>{{x.address}}</td>
        <td>{{x.pass}}</td>
    </tr>
</table>

以下是我的js代碼：

var app = angular.module("myApp", ['ngRoute','ngStorage']);
app.controller("userCtrl",['$scope','$localStorage','$log',function($scope,$localStorage,$log){
    $scope.userArray=[];
    $scope.userdata=$localStorage.data;

    $scope.addItem=function(user){    
        //var current=$localStorage.data;
        //$scope.userArray=userArray.concat(user);
        $log.log($scope.userArray);
        $scope.userArray.push(user);
        $localStorage.data=$scope.userArray;
        $scope.userdata=$localStorage.data;
    }

}]);

數據將存儲在本地存儲中

但是每次我單擊按鈕時，它都會覆蓋本地存儲中的數據。

有人知道怎么做這個嗎？

在將userArray壓入后，您必須先清除用戶對象

$scope. user = {};

這是鏈接Jsfiddle演示

$scope.addItem = function(user) {
  $scope.userArray.push(user);
  $scope.user = {};
  $localStorage.data = $scope.userArray;
  $scope.userdata = $localStorage.data;
}
