ng-repeat中的角度无限$digest循环 [英] angular Infinite $digest Loop in ng-repeat
本文介绍了ng-repeat中的角度无限$digest循环的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想在 ng-repeat 属性中调用函数，这是我的代码
html
<div ng-repeat='item in getGroupedRange() track by item.id'><span>{{item.val}}</span><span>{{item.abs}}</span><span>{{item.rel}}</span><span>{{item.cum}}</span>js
$scope.getGroupedRange = function() {返回 [{价值:1，腹肌:1，相对:1，暨: 1,编号:123456}];};当我打开控制台时，我注意到错误
10 $digest() 迭代达到.中止！在最后 5 次迭代中触发观察者: [[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":9,"oldVal":8}],[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":10,"oldVal":9}],[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":11,"oldVal":10}],[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":12,"oldVal":11}],[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":13,"oldVal":12}]]我的代码的主要目标是使用 ng-repeat 中的函数来计算每个事件循环中的数据
解决方案
找到解决方案:
$scope.prev = null;$scope.getGroupedRange = function() {变量数据 = [{价值:1，腹肌:1，相对:1，暨: 1,编号:123456}];如果(angular.equals($scope.prev，数据)){返回 $scope.prev;}$scope.prev = 数据；返回数据；};I want to call function in ng-repeat attribute, here is my code
html
<body ng-controller="mainCtrl">
<div ng-repeat='item in getGroupedRange() track by item.id'>
<span>{{item.val}}</span>
<span>{{item.abs}}</span>
<span>{{item.rel}}</span>
<span>{{item.cum}}</span>
</div>
</body>
js
$scope.getGroupedRange = function() {
return [
{
val: 1,
abs: 1,
rel: 1,
cum: 1,
id: 123456
}
];
};
When I opened console I noticed the error
10 $digest() iterations reached. Aborting!
Watchers fired in the last 5 iterations: [[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":9,"oldVal":8}],[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":10,"oldVal":9}],[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":11,"oldVal":10}],[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":12,"oldVal":11}],[{"msg":"fn: function (c,d,e,f){e=a(c,d,e,f);return b(e,c,d)}","newVal":13,"oldVal":12}]]
The main goal of my code is using function in ng-repeat for calculating data in each event loop
解决方案
Found the solution:
$scope.prev = null;
$scope.getGroupedRange = function() {
var data = [{
val: 1,
abs: 1,
rel: 1,
cum: 1,
id: 123456
}];
if (angular.equals($scope.prev, data)) {
return $scope.prev;
}
$scope.prev = data;
return data;
};
