使用Javascript或Lodash更新嵌套数组中的对象属性
使用Javascript或Lodash更新嵌套数组中的对象属性
提问于 2020-06-18 13:16:05
我有嵌套的数组，每个对象都包含唯一的path属性。所以我想根据条件更新value属性。下面是引用JSON对象
因此需要在下面JSON where path=httpgateway.concurrency.cacheConfig.localConcurrent.0.servers.1中更新对象
假设当前值为localhost:9011，但我想要它为localhost:9012

"type": "Object",
"value": [
{
"name": "concurrency",
"type": "Object",
"value": [
{

你可以用纯JS来实现，如下所示：
const updateKey = (obj, path, value) => {
if (obj.path === path) {
obj.value = value;
return obj;
}
if (!Array.isArray(obj.value)) {
return obj;
}
obj.value = obj.value.map(item => updateKey(item, path, value));
return obj;
};
const updated = updateKey(data, 'httpgateway.concurrency.cacheConfig.localConcurrent.0.servers.1', 'localhost:9012');页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
