] 并且由爷爷分组结果＆＃39;和父母＆＃39;属性我使用了lodash.js，如下所示：

var nest = function (seq, keys) {
        //console.log(keys.length)
        if (!keys.length)
            return seq;
        var first = keys[0];
        var rest = keys.slice(1);
        return _.mapValues(_.groupBy(seq, first), function (value) {
            return nest(value, rest)
        });
    };
var nested = nest(result, ['grandpa','parent']);

并返回＆＃34;嵌套＆＃34;到ng-repeat里面的视图，＆＃39;嵌套＆＃39;是什么＆＃39; searchFor＆＃39;过滤器返回：

<div ng-repeat="node in filteredModules = (modules | searchFor:searchString track by $index">    
    {{node.name}}    
</div>

但它导致了这个问题，我无法弄清楚原因。

错误：[$ rootScope：infdig] 10 $ digest（）迭代达成。中止！观察者在最后5次迭代中被解雇：[[{＆＃34; msg＆＃34;：＆＃34; fn：regularInterceptedExpression＆＃34;，＆＃34; newVal＆＃34;：119，＆＃34; oldVal＆＃34; ：115}]，[{＆＃34; msg＆＃34;：＆＃34; fn：regularInterceptedExpression＆＃34;，＆＃34; newVal＆＃34;：123，＆＃34; oldVal＆＃34;：119}] ，[{＆＃34; msg＆＃34;：＆＃34; fn：regularInterceptedExpression＆＃34;，＆＃34; newVal＆＃34;：127，＆＃34; oldVal＆＃34;：123}]，[{＆＃34; msg＆＃34;：＆＃34; fn：regularInterceptedExpression＆＃34;，＆＃34; newVal＆＃34;：131，＆＃34; oldVal＆＃34;：127}]，[{＆＃34; msg＆＃34;：＆＃34; fn：regularInterceptedExpression＆＃34;，＆＃34; newVal＆＃34;：135，＆＃34; oldVal＆＃34;：131}]]

注意：当我将结果返回到视图而不对数据进行分组时，它不会导致该问题。当打印＆＃39;嵌套＆＃39;在控制台中没有在视图上查看它，它运行良好，不会导致错误。这里试图解释更多：https://jsfiddle.net/qw332bkc/

编辑：是否有另一种方法可以将结果分组给爷爷＆＃39;和父母＆＃39;属性？

我也遇到过这个

为我解决这个问题的是从js脚本文件中过滤而不在ng-repeat标记中进行过滤操作

因此，在您的情况下，解决方案可能是在控制器中创建过滤函数，并且该函数将在每次触发时将排序数组分配给$ scope。然后，从ng-repeat中重复遍历整个数组。

编辑：

问题在于你每次都在创建一个新数组，所以它是一个角度需要跟踪的新东西。据我所知，ng-repeat运行，然后立即再次检查其集合，以查看该循环中是否有任何变化。因为该函数返回一个新数组，这被视为一个变化。

取自： AngularJS InfDig error (infinite loop) with ng-repeat function that returns array of objects

由ng-repeat和搜索过滤器结果引起的无限循环
