我有一个这样的对象：
Exception:03-14 17:39:19.268: E/AndroidRuntime(1236): java.lang.RuntimeException: Unable to

首次启动控制器时， .controller('lineCtrl', function($sessionStorage, $rootScope, $scope, $stateParams, $state, $filter, config, $http, SCAN_EVENT, $ionicLoading, $ionicPopup, ScanService){
var areaName;
var lineCounts;
function filterObjects () {
switch ($stateParams.area) {
case 'PW':
$scope.items = $filter('filter')($rootScope.runnerItemsPW, {line: $stateParams.line}, true);
areaName = "Putwall";
lineCounts = $rootScope.lineCountPW;
break;
case 'NC':
$scope.items = $filter('filter')($rootScope.runnerItemsNC, {line: $stateParams.line}, true);
areaName = "Non-Con";
lineCounts = $rootScope.lineCountNC;
break;
case 'RE':
$scope.items = $filter('filter')($rootScope.runnerItemsRE, {line: $stateParams.line}, true);
areaName = "Receiving";
lineCounts = $rootScope.lineCountRE;
break;
case 'SP':
$scope.items = $filter('filter')($rootScope.runnerItemsSP, {line: $stateParams.line}, true);
areaName = "Singles Pack";
lineCounts = $rootScope.lineCountSP;
break;
default:
break;
}
}
filterObjects();
$rootScope.lineData = {
position: 1,
lineNumber: $stateParams.line,
area: $stateParams.area,
areaName: areaName,
lineCounts: lineCounts,
items: $scope.items
};
$scope.clearLine = function(){
ScanService.dispatch(String("00" + $rootScope.lineData.lineNumber).slice(-2) + 'DONE');
};
$scope.removeStationItems = function (stationdID, createdDateTime){
var url = config.baseURL + "/runner/removeDesktopRunnerItem/" + stationdID + "/" + createdDateTime.split(' ').join('_') + "/" + $sessionStorage.user.loginName;
$http.get(url).then(function(response){
if(response.status === 200 && response.statusText === "OK"){
var data = response.data;
if(data === ''){
$state.go($rootScope.prevState);
$rootScope.setObjects(data);
filterObjects();
}else{
$rootScope.setObjects(data);
filterObjects();
var found = $filter('getByStationID')(data.runnerItems, $rootScope.lineData.lineNumber);
if(found === null){
$state.go($rootScope.prevState);
}
}
}
})
};
})
.controller('queue', function ($rootScope, $http, $filter, $scope, config, $interval, $ionicLoading) {
$rootScope.setObjects = function (data){
$rootScope.runnerItemsPW = $filter('filter')(data.runnerItems, {areaShort: "PW"});
$rootScope.lineCountPW = $filter('filter')(data.lineCounts, {areaShort: "PW"});

};
});
会添加到对象中，并且工作正常。当新数据进入时，行$scope.items会更新。但是，$scope.items的ng-repeat不会更新。

$ filter创建一个新对象，因此需要更新$ rootScope.lineData。过滤后再次更新$ rootScope.lineData。
答案 1 :(得分：1)
重新分配$scope.items时，您正在破坏原始对象引用，因此传递给lineData对象的原始引用不再与$scope.items引用的数组相同
简单示例
var myArray = [1,2,3];
var obj={
items: myArray // reference to array above
}
console.log(myArray ); // [1,2,3]
console.log(obj.items); // [1,2,3] - exact same object reference as myArray
// now reassign myArray with new object reference
myArray =[6,7,8];
console.log(myArray ); // [6,7,8]
console.log(obj.items); // [1,2,3] - the original reference hasn't changed
// now reassign object property value to new array
obj.items = myArray ;
console.log(obj.items); // [6,7,8] - references new array
注意：您应该使用服务跨控制器共享数据和方法。
答案 2 :(得分：0)
您只在控制器初始化函数中分配给$rootScope.lineData一次。在引导过程中，此函数仅被调用一次。
您还需要在filterObjects功能中分配它，以便通过$http电话更新它。这意味着您需要在第一次调用filterObjects之前创建它。像这样：
$rootScope.lineData = {
position: 1,
lineNumber: $stateParams.line,
area: $stateParams.area,
areaName: areaName,
lineCounts: lineCounts,
};
function filterObjects () {
switch ($stateParams.area) {
case 'PW':
$rootScope.lineData.items = $scope.items = $filter('filter')($rootScope.runnerItemsPW, {line: $stateParams.line}, true);
areaName = "Putwall";
lineCounts = $rootScope.lineCountPW;
break;
// etc.
}
}
filterObjects();
答案 3 :(得分：-2)
在$ http响应代码中添加行$ scope。$ apply（）;在调用函数filterObjects（）
之后
