我有一个数组，我想迭代和过滤出来的基于另一个数组的键。我需要迭代通过第一个数组，并删除该项目，如果代码匹配从第二个数组。我知道我应该使用数组过滤器，但我无法了解如何将第二个数组作为过滤器。通过阵列与另一个阵列的值过滤
var arr =[

'arr'是一个数组* *阵列，和'el'是一个字符串数组。通过执行'e！== el'，你可以将一个对象数组与一个字符串数组进行比较，这不仅不起作用，而且完全不是你想要做的。您必须过滤内部数组，其中'el'不包含内部数组对象的'code'属性。或者*包含 - 你的问题和代码似乎在做两件不同的事情。 – Santi
如果您的代码段更简洁，这将会有所帮助。其次 - 为什么你要在数组中创建一个对象数组？如果你不需要反对，那数据结构并不理想。 – zfrisch
您当前的[filter]（https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter）函数不会解决复杂的数据模式。 –
