Question

我在index.php文件中设置了一个php会话变量。使用ng-init我将该会话值分配给变量，以便我可以在我的angularjs控制器文件中使用。这是我的index.php文件

<body ng-app="myApp">
    <div ng-controller="restaurantController" ng-init="total=0;something='<?php echo $_SESSION['rname'] ?>'" class="container">
        <div class="col l4 s4 container">
        <label>Search</label>    <input type="text" ng-model="search.name">
    </div>
        <div ng-repeat="item in items | filter:search" class="container">
            <h3>{{item.name}}</h3>
            <p>category:{{item.category}}</p>
            <p>price:INR {{item.price}} /-</p>
            <br/>
            <button ng-hide="item.added"  ng-click="process(item)">Add</button>
            <button ng-show="item.added" class="ng-cloak">Remove</button>
        </div>
        <h1>Total:<span ng-model="total">{{total}}</span></h1>
    </div>
    <script src="../angular/app.js"></script>
    <script src="../angular/restaurantController.js"></script>
    <script src="../materialize/js/materialize.min.js"></script>
</body>

这里将变量分配给php会话变量。但是当我在控制器文件中使用$ scope.something时，我得到了未定义。这是我的控制器文件

var myApp = angular.module('myApp',[]);
myApp.controller('restaurantController',['$scope','$http', function($scope, $http){
    $http.get($scope.something+'.json').success(function (data){
        $scope.items = data;
    });

    $scope.process = function(item){
        $scope.total = parseInt($scope.total) + parseInt(item.price);
        item.added=true;
    }
}]);

$ scope.something的值在控制器文件中未定义，但在php文件中我得到了正确的值。

<body ng-app="myApp" ng-init="total=0;something='<?php echo $_SESSION['rname'] ?>'">
    <div ng-controller="restaurantController"  class="container">
        <div class="col l4 s4 container">
        <label>Search</label>    <input type="text" ng-model="search.name">
    </div>
        <div ng-repeat="item in items | filter:search" class="container">
            <h3>{{item.name}}</h3>
            <p>category:{{item.category}}</p>
            <p>price:INR {{item.price}} /-</p>
            <br/>
            <button ng-hide="item.added"  ng-click="process(item)">Add</button>
            <button ng-show="item.added" class="ng-cloak">Remove</button>
        </div>
        <h1>Total:<span ng-model="total">{{total}}</span></h1>
    </div>
    <script src="../angular/app.js"></script>
    <script src="../angular/restaurantController.js"></script>
    <script src="../materialize/js/materialize.min.js"></script>
</body>

得到了解决方案。只需更改ng-init的位置，以便在页面加载后立即初始化变量。
