嗨，我需要幫助，我需要從上面的 json 中獲取所有“類：人”的資料。怎么做？

請試試這個
const ids = ["person"];
const data = [
{
"bbox":[
24.24112319946289,
15.165281295776367,
560.5425834655762,

],
"class":"person",
"score":0.8514186143875122
},
{

],
"class":"person",
"score":0.5516218543052673
}
];
const data2 = data.filter( i => ids.includes( i.class ) );
console.info( data2 );uj5u.com熱心網友回復：
[更新]：
您可以filter通過陣列獲取所需的物件：
const person = json.filter((item) => item.class === 'person')
這將回傳具有class鍵值的物件person
