我很震驚,無法理解這裏的問題。 我使用HTTP服務呼叫我的JSON文件 廠(accountInfo.json)創建一個工廠:卡住了:AngularJs使用http調用json的工廠
appRoot.factory('accountInfo', ['$http', function($http) {
return $http.get('../../accountInfo.json')
.success(function(data) {
return data;
})
.error(function(err) {
return err;
});
}]);
控制器(AccountsController.js)
appRoot.controller('AccountsController', ['$scope', 'accountInfo', function($scope, accountInfo){
accountInfo.success(function(data) {
$scope.rows = data;
});
$scope.totals = {
name: '',
marketValue: 0,
cash: 0,
legend: 'none'
};
for (var i = 0; i < $scope.rows.length; i++) {
$scope.totals.marketValue += $scope.rows[i].marketValue;
$scope.totals.cash += $scope.rows[i].cash;
}
$scope.addAccount = function() {
$scope.rows.push({
name: 'New Account',
marketValue: Math.random() * 100000,
cash: Math.random() * 400000,
legend: 'cyan'
});
}
}]);
我的JSON(accountInfo.json)
[{
"name": "Brokerage Account 3",
"marketValue": 1999990,
"cash": 1995826,
"legend": "orange"
},
{
"name": "Account 3",
"marketValue": 1949990,
"cash": 1695856,
"legend": "darkorange"
},
{
"name": "Brokerage Account 1",
"marketValue": 1349990,
"cash": 1595866,
"legend": "red"
},
{
"name": "Brokerage Account 4",
"marketValue": 155990,
"cash": 160826,
"legend": "blue"
},
{
"name": "Brokerage Account 2",
"marketValue": 74560,
"cash": 19956,
"legend": "gray"
},
{
"name": "Account 4",
"marketValue": 55006,
"cash": 53006,
"legend": "salmon"
},
{
"name": "Account 13",
"marketValue": 37340,
"cash": 0,
"legend": "green"
},
{
"name": "Joint Account 1",
"marketValue": 28308,
"cash": 4167,
"legend": "darkblue"
},
{
"name": "Joint Account 2",
"marketValue": 10000,
"cash": 10000,
"legend": "teal"
}]
我收到的錯誤是「$ scope.rows is undefined」 控制器無法訪問$ scope.rows以外的s訪問功能。
謝謝:)
那麼,這是什麼問題? –
