Question

我的主要Json对象是一个Job，附加到它是ChangeOrders，PurchaseOrders，JobItems等....我无法访问JobItems。我已经设置了一个plunkr，但问题是我不知道如何重新创建Json结构，所以它实际上正在工作。设置plunkr的方式是我如何访问ChangeOrders，它允许我访问数组中的所有对象：

typeahead="c.ChangeOrders[0].COName for c in jobArray

但是当我将它用于我的JobItems时，我只访问Array中的第一个JobItem。 plunkr

<input class="form-control input-md" style="width:200px" type="text" ng-model="jobItem.JobItemName"
     typeahead="jobItem.JobItems[0].JobItemName for jobItem in jobArray | filter:$viewValue"
     typeahead-on-select="selectJobItem($item)" ng-enter="addRecord()" placeholder="Job Items">

JSON

更新

 //GET Jobs
$scope.jobArray = {};
JobGet.query().then(function (data) {
    $scope.jobArray = data;
}, function (reason) {
    errorMngrSvc.handleError(reason);
});
app.factory('JobGet', function ($http, $q) {
  return {
    query: function () {
        var deferred = $q.defer();
        $http({ method: 'get', url: '/api/apiJob' })
                .success(function (data) {
                    deferred.resolve(data);
                }).error(function (error) {
                    deferred.reject(error);
                });
        return deferred.promise;
      }
    }
 });

this之类的东西是你在寻找什么？

修改的重点（据我理解的问题）是：

// Accumulate all JonItems in one array which will be used in typeahead
angular.forEach($scope.jobArray, function(job){
    angular.forEach(job.JobItems, function(item){
        $scope.allJobItems.push(item);
    });
});

还要注意输入的更改：

typeahead="itemName as item.JobItemName for item in allJobItems | filter:$viewValue"

同样的原则适用于ChangeOrders和PurchaseOrders。另请注意，每个项目都会添加更多JobItems，因此预先输入将适用于所有项目。

我希望这个答案会很明确，但是如果仍然不清楚那么修改plunker并添加ChangeOrders和PurchaseOrders并让我知道你是否被卡住了。
