具有字段和子對象數組的對象的JavaScript數組？

Question

爲什麼這是無效的JavaScript？我有個數組。數組中的每個項目都有一個標題字段，也是一個子數組。子數組具有包含img字段的對象，有時也包含內容字段。

const content = [ 
    { 
    "title": "First title", 
    [ 
     {"img": img1, "content": "This is content"}, 
     {"img": img2}, 
     {"img": img3} 
    ] 
    }, 
    { 
    "title": "Second title", 
    [ 
     {"img": img4, "content": "This is also content"}, 
     {"img": img5}, 
     {"img": img6} 
    ] 
    } 
]; 

Answer 1

沒有嵌套數組的屬性名稱。

const content = [ 
{ 
    "title": "First title", 
    "missingKey1" : [ 
     {"img": img1, "content": "This is content"}, 
     {"img": img2}, 
     {"img": img3} 
    ] 
    }, 
    { 
    "title": "Second title", 
    "missingKey2" : [ 
     {"img": img4, "content": "This is also content"}, 
     {"img": img5}, 
     {"img": img6} 
    ] 
    } 
];
