AngularJS-创建多维数组

Question

使用一个拖放插件传递数据，ondrop事件获取数据，如下

Ctrl

var streamArr = [];
$scope.onDrop = function (data, dragElement, dropElement, event) {
    streamArr.push({'userId':userId,'divid':divId,'userName':userName,'streamingState':$rootScope.route});
});

输出

10
divPictureBox00
User1
live

现在，每当用户放下东西时，我都需要将数据推送到一个数组中，这样得到的itesm就会低于

streamArr: [
{userId: 10, divId: 'divPictureBox00', userName: 'User1', streamingState:'live'},
{userId: 11, divId: 'divPictureBox01', userName: 'User2', streamingState:'live'},
{userId: 12, divId: 'divPictureBox02', userName: 'User3', streamingState:'recorded'},
{userId: 10, divId: 'divPictureBox00', userName: 'User1', streamingState:'live'},
]

但数据并没有被推送到该数组中。我该怎么做？

Answer 1

这是因为您始终在处理同一个对象。尝试在每次调用函数时创建一个新对象，然后在数组中推送该对象。

var streamArr = [];
$scope.onDrop = function (data, dragElement, dropElement, event) {
var obj = new Object();
obj.userId = userId;
obj.divId = divId;
obj.userName = userName;
obj.streamingState = $rootScope.route;
streamArr.push(obj);

})；
