我正在尝试过滤一个深度“复杂”嵌套对象数组！尝试使用_.filterDeep（）进行计算。

]实际功能：
function arrayFilter(products_array, searchVal = 'PUL') {
let list = _.filterDeep(
products_array,
function(value, key) {
if (key == 'code') {
return value.indexOf(searchVal) >= 0;
}
},
{
onTrue: { skipChildren: false },
}
);
console.log(list);
}从技术上讲，该函数可以工作，但错误是层次结构和其他对象键从数组中删除。
我试图保持父层次结构，如果任何对象仍然在子数组中。
尝试搜索很多不同的解决方案，如{ childrenPath:'products_list' } -- option来声明子属性名，使deepdash在“树模式”下工作
任何帮助都非常感谢。：）

OK，找到解决方案了：）
我根据这个最佳答案简化了子数组的键名：Recursively filter array of objects
新数组结构：
和函数：
也许可以帮助别人;）
