如何解决角＆QUOT; 10 $摘要（）迭代达到＆QUOT;错误 [英] How to Troubleshoot Angular "10 $digest() iterations reached" Error

问题描述

10 $digest() iterations reached. Aborting!

有很多的，在过去的5次迭代解雇看守：意义上的配套文本等等，但很多这样的文字是各种功能的Javascript code。对于诊断这个问题拇指有规则吗？难道总是可以减轻，还是有应用足够复杂，这个问题应该只是一个警告来处理问题吗？

There is a lot of supporting text in the sense of "Watchers fired in the last 5 iterations: ", etc., but a lot of this text is Javascript code from various functions. Are there rules of thumb for diagnosing this problem? Is it a problem that can ALWAYS be mitigated, or are there applications complex enough that this issue should be treated as just a warning?

推荐答案

作为法师说，你要么返回不同的（不完全相同）对象上的每个 $消化周期，或者你正在改变数据的次数太多了。​​

as Ven said, you are either returning different (not identical) objects on each $digest cycle, or you are altering the data too many times.

最快的解决方案，以找出您的应用的一部分，是造成这种行为是：

1. 删除所有可疑的HTML - 基本上都是从模板中删除所有的HTML，并检查是否有任何警告


2. 如果没有警告 - 你取出的HTML添加小部件检查问题又回来了


3. 重复步骤2，直到你得到一个警告 - 你会找出其中你的HTML的一部分，负责问题


4. 进一步调查 - 部分从第3步是负责要么变异的 $范围的对象或者是在每区选出不相同的物体 $摘要周期


5. 第1步后，如果仍然有 $消化反复警告，比你可能做的事情很可疑。重复父模板/范围/控制器相同的步骤

1. remove all suspicious HTML - basically remove all your html from the template, and check if there are no warnings
2. if there are no warnings - add small parts of the html you removed and check if the problem is back
3. repeat step 2 until you get a warning - you will figure out which part of your html is responsible for the problem
4. investigate further - the part from step 3 is responsible for either mutating the objects on the $scope or is returning non-identical objects on each $digest cycle.
5. if you still have $digest iteration warnings after step 1, than you are probably doing something very suspicious. Repeat the same steps for parent template/scope/controller

您也想确保你不改变你的自定义过滤器的输入

请记住，在JavaScript中有没有表现得像你特定类型的对象通常期望：

Keep in mind, that in JavaScript there are specific types of objects that don't behave like you would normally expect:

new Boolean(true) === new Boolean(true) // false
new Date(0) == new Date(0) // false
new String('a') == new String('a') // false
new Number(1) == new Number(1) // false
[] == [] // false
new Array == new Array // false
({})==({}) // false
