Question

我有一系列药物代码'BARB', 'HALU', 'METH'。我想循环遍历这些代码并为每个代码创建一个新对象。

var saveObj = {};
saveObj.SelectedList = [];
angular.forEach(self.DrugNamesSelected, function(value, key) {
    //Load Objects into array
    var newObj = {};
    newObj = self.Selected;
    newObj.FK_CLNT_PERSFK_PER = $routeParams.personId;
    newObj.DRUG_TYP_CODE = value;
    saveObj.SelectedList.push(newObj);
});

这就是我得到的

saveObj.SelectedList [0] .DRUG_TYP_CODE ='METH' saveObj.SelectedList [1] .DRUG_TYP_CODE ='METH' saveObj.SelectedList [2] .DRUG_TYP_CODE ='METH'

这就是我需要的

saveObj.SelectedList [0] .DRUG_TYP_CODE ='BARB' saveObj.SelectedList [1] .DRUG_TYP_CODE ='HALU' saveObj.SelectedList [2] .DRUG_TYP_CODE ='METH'

好像An unhandled exception occurred while processing the request. AmbiguousActionException: Multiple actions matched. The following actions matched route data and had all constraints satisfied: GLibrary.Controllers.SecurityController.Login (GLibrary) PLibrary.Controllers.SecurityController.Login (PLibrary)让你有问题。所以发生的事情是每个元素都存储newObj = self.Selected;的引用（即所有对象都指单个内存引用）。因此，当最后一个值更新为self.Selected时，所有3个元素都具有相同的METH值。

self.Selected

如果您出于某种原因需要该特定对象分配，我建议您使用angular.forEach(self.DrugNamesSelected, function(value, key) { //Load Objects into array var newObj = {}; //newObj = self.Selected; //removed this line newObj.FK_CLNT_PERSFK_PER = $routeParams.personId; newObj.DRUG_TYP_CODE = value; saveObj.SelectedList.push(newObj); });将Object.assign属性复制到self.Selected。

newObj

IE11不支持Object.assign(newObj, self.Selected)开箱即用。您可以考虑从here

添加相同的polyfill

Angularjs通过forEach将对象加载到数组中
