//我的需求就是当点击 "获取timeout的索引" 按钮后 将这些timeout的状态在重新请求,如果请求成功,就会把timeout显示成on.
//因为循环请求有时会timeout超时
//所以现在最大的问题就是怎么把 timeout重新请求.然后修改$rootScope.arr数组的相应下标位置,重点就在这里

}My requirement is to re-request the timeout status after clicking the "Get timeout index" button. If the request is successful, the timeout will be displayed as on.
Because the cyclic request sometimes times out
So the biggest problem now is how to re-request the timeout. Then modify the corresponding subscript position of the $rootScope.arr array. The focus is here

The comment said that traversing arr is correct,
You imagine, I get the object whose attribute is timeout in this array, and its index value in this array
You may want to make a judgment directly at the front desk, you can do it, but it is not recommended
