Parsing JSON String in AngularJS - Gives undefined
提问by iCode
Hi I have a code like following in my controller
嗨，我的控制器中有如下代码
myClientApp.controller('ListCtrl', function ($scope,$http,$cookieStore,$location, $routeParams) {
var data = {
"menus": {
"view": true,
"add": true,
"update": true,
"delete": true
},
"linkInfo": {
"labelColumn": "codeName",
"linkColumn": "lookupKey",
"urlInfo": "reference"
},
"resultList": [
"{\"lookupKey\":2,\"clientKey\":1,\"codeName\":\"Application.AppType\",\"codeValue\":\"ApplicationType2\",\"codeDesc\":\"##\",\"updatedBy\":null,\"internalCodeName\":\"Application.AppType\"}",
"{\"lookupKey\":3,\"clientKey\":1,\"codeName\":\"Application.Class\",\"codeValue\":\"Tier 1\",\"codeDesc\":\"Critical Application requiring immediate response in case of a disruption of Service\",\"updatedBy\":null,\"internalCodeName\":\"Application.Class\"}"
]
};
$scope.result = angular.fromJson(data.resultList);
alert($scope.result[0].codeName);
});
And It gives me undefined. Why?
它给了我undefined。为什么？

Because resultListis an array of JSON strings, not a single JSON string; you need to specify which key you want to decode:
因为resultList是一个 JSON 字符串数组，而不是单个 JSON 字符串；您需要指定要解码的密钥：
$scope.result = [
angular.fromJson(data.resultList[0]),
angular.fromJson(data.resultList[1])
];
alert($scope.result[0].codeName);
