假设您有一个非常大的导航,大约有15个嵌套级别,例如:
var app = angular.module("myApp", []);
app.controller("HomeCtrl", ["$scope", function($scope) {
this.entries = [{
"title": "test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test",
"entries": [{
"title": "sub-test"
}]
}]
}]
}]
}]
}]
}]
}]
}]
}]
}]
}]
}];
return this;
}]);
您正在使用ng-repeat
<script type="text/ng-template" id="entryTree">
<span>{{ entry.title }}</span>
<ol ng-if="entry.entries">
<li ng-repeat="entry in entry.entries" ng-include="'entryTree'"></li>
</ol>
</script>
<div ng-controller="HomeCtrl as ctrl">
<ol>
<li ng-repeat="entry in ctrl.entries" ng-include="'entryTree'"></li>
</ol>
</div>
然后会抛出$rootScope:infdig
错误:10 $digest() iterations reached. Aborting!
。我知道这里有几个类似的问题(例如this one)。但在我的情况下,我没有从控制器返回动态值,也没有使用动态getter,我只是静态地保存控制器内的值。
这里的原因是什么?解决方案怎么样?
答案 0 :(得分:1)
由于ng-include,模板的每次迭代都会导致新的摘要循环。当一个摘要循环导致另一个循环,并以这种方式循环10次时,angular假定它可能是一个无限循环并抛出错误。
