角无限$消化在循环NG-重复 [英] angular Infinite $digest Loop in ng-repeat
本文介绍了角无限$消化在循环NG-重复的处理方法，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
我要调用函数在NG-repeat属性，这里是我的code
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
}
];
};
当我打开控制台我发现错误
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}]]
的我的code的主要目标是在NG-重复使用的功能在每个事件循环计算数据的
谢谢！
推荐答案
找到了解决办法：
$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;
};
