我有一个类似的[简化]JSON文件
{
"id":87,
"meta_data":[
{
"id":1232,
"key":"user_created_by",
"value":"example@gmail.com"
},
{
"id":1233,
"key":"user_created_at",
"value":"1659890457477"
},
{
"id":1234,
"key":"good_person_or_silly_sausage",
"value":"No"
}
]
}
我想做一些类似的事情
Logger.log(orderDetailsObject.meta_data.value[key="good_person_or_silly_sausage"])
预期值为
无
然而，事实并非如此。目前我被告知该对象为空。
我想这是因为meta_data对象是对象或二维数组中的对象吗？，我不太了解我在这里做什么
我觉得https://docs.jsonata.org/simple和https://docs.jsonata.org/predicate应该引导我找到答案——但我没有得到我认为的东西。
我是SO和JSON&Javascript-所以请温柔一点<3

您可以在数组上使用find方法：
const orderDetailsObject = {"id":87,"meta_data":[{"id":1232,"key":"user_created_by","value":"example@gmail.com"},{"id":1233,"key":"user_created_at","value":"1659890457477"},{"id":1234,"key":"good_person_or_silly_sausage","value":"No"}]};
console.log(orderDetailsObject.meta_data.find(
({key}) => key == "good_person_or_silly_sausage"
)?.value);
