【问题描述】:
一个例子: 该代码由该 HTML 触发:
<div google-chart chart = "chartObject" style = "height:600px; width:100%;" agc-on-select="selectHandler(selectedItem)" ng-if="chartvisible"></div>
这将创建一个 UI 网格:
$scope.gridOptions = gridService.getGrid([25, 50, 75], 25, ['username','startTime']);
$scope.gridOptions.data = post;
$scope.$apply();
变量“Post”类似于:
[
{
"challenge": "asdfrew2",
"id": 1,
"startTime": "start time 1",
"successfullyCompleted": false,
"username": "JamieFalter"
},
{
"challenge": "454454y",
"id": 2,
"startTime": "start time 2",
"successfullyCompleted": false,
"username": "Falter"
}
]
返回如下所示的错误:
TypeError:将循环结构转换为 JSON
at na (angular.js:1121) at angular.js:20566 at Object.fn (angular.js:12411) at k.$digest (angular.js:12540) at k.$apply (angular.js:12805) at Object.<anonymous> (Controller.js:54)//Points to the Scope.Apply at i (jquery.min.js:2) at Object.fireWith [as resolveWith] (jquery.min.js:2) at y (jquery.min.js:4) at XMLHttpRequest.c (jquery.min.js:4)
有没有人见过这样的事情?如果有,你是怎么解决的?
【问题讨论】:
-
为什么需要申请?该错误看起来像 JSON 指向它自己产生循环引用。
-
我这样做是为了注意到 gridoptions8 的“数据”字段的更改。
