angularjs将值附加到数组中

Question

我有以下格式的数组。我有问题追加每个章节数组内的值。我需要添加像'checked：true'字段。我需要以相同的格式获取数据。期望的是，需要在章节数组中添加一个字段的相同格式。

{ 
    "Books": [ 
    { 
     "label":"Book1", 
     "data": [ 
     { 
      "bookId": 3561, 
      "bookName": "AJ200", 
      "chapters": [ 
      { 
       "id": 3926, 
       "name": "red" 
      }, 
      { 
       "id": 3927, 
       "name": "yellow" 
      }, 
      { 
       "id": 3928, 
       "name": "black" 
      } 
      ] 
     } 
     ] 
    }, 
    { 
     "label":"Book2", 
     "data":[ 
     { 
      "bookId": 3561, 
      "bookName": "AJ200", 
      "chapters": [ 
      { 
       "id": 3564, 
       "name": "blue" 
      }, 
      { 
       "id": 3565, 
       "name": "orange" 
      } 
      ] 
     } 
     ] 
    } 
    ] 
} 

加场章节阵列看起来像下面后，

"chapters": [ 
      { 
       "id": 3564, 
       "name": "blue", 
       "checked":true 
      }, 
      { 
       "id": 3565, 
       "name": "orange" 
       "checked":true 
      }

这是一个有点冗长，但工作原理都是一样的！

var myObject = 
{ 
    "Books": [ 
    { 
     "label":"Book1", 
     "data": [ 
     { 
      "bookId": 3561, 
      "bookName": "AJ200", 
      "chapters": [ 
      { 
       "id": 3926, 
       "name": "red" 
      }, 
      { 
       "id": 3927, 
       "name": "yellow" 
      }, 
      { 
       "id": 3928, 
       "name": "black" 
      } 
      ] 
     } 
     ] 
    }, 
    { 
     "label":"Book2", 
     "data":[ 
     { 
      "bookId": 3561, 
      "bookName": "AJ200", 
      "chapters": [ 
      { 
       "id": 3564, 
       "name": "blue" 
      }, 
      { 
       "id": 3565, 
       "name": "orange" 
      } 
      ] 
     } 
     ] 
    } 
    ] 
} 

var books = myObject.Books; 


for(var i=0; i<books.length; i++) { 

    var bookData = books[i].data; 

    for(var j=0;j<bookData.length;j++) { 

    var chapters = bookData[j].chapters; 

    for(var k=0;k<chapters.length;k++) { 

     chapters[k].checked = true; 

    } 

    } 

} 

console.log(JSON.stringify(books));
