Array Of Objects To Array Of Array Came As A String

I have JSON object oAtt declared as var oAtt = MessageStore.message().attachments(); MessageStore.message() is declared in the code available here: https://github.com/RainLoop/rain

Solution 1:

I cannot reproduce your problem. What is oArr tho? You are talking about oAtt and aAtt in your code.

var oAtt = [{
    "sModelName": "AttachmentModel",
    "disposables": [],
    "mimeType": "application/pdf",
    "fileName": "sample.pdf",
    "fileNameExt": "pdf",
    "fileType": "pdf",
    "description": null,
    "estimatedSize": 19333,
    "friendlySize": "19KB",
    "isInline": false,
    "isLinked": false,
    "isThumbnail": false,
    "cid": "",
    "cidWithOutTags": "",
    "contentLocation": "",
    "download": "zyfTZvzczVW6cqlcsIrm3ycmY5soz3DzK5sZhjnSOwaW0wnwGwHtqBvPeo8nVpiWD4yKVIPvAPauJHZufHGRG0Eb4MRmBpkGlvsDGP-gz3CnVp4GorN_xXCI0Gkd2I93IySKMy5iXRt-wML9wxLwTZcrOMLyPp-Kr6b0GlzlHuvk3RqEXRqSlCQTX5piRO6AaRYeMKeq8PSJcId1grMYzFpCnjVSoW_Zj7yTGAsy-D_mzFoCmBdksCweEqPdGhFYFkukblXzaZiTSNGTj1xYOvMIN4XXUZtU0EAPoQ9EFxfPWY_-1Siyge0Gks2zbGs3myxXJg..",
    "folder": "INBOX",
    "uid": "22",
    "mimeIndex": "2",
    "framed": false
  },
  {
    "sModelName": "AttachmentModel",
    "disposables": [],
    "mimeType": "image/jpeg",
    "fileName": "test4.jpg",
    "fileNameExt": "jpg",
    "fileType": "image",
    "description": null,
    "estimatedSize": 26326,
    "friendlySize": "26KB",
    "isInline": false,
    "isLinked": false,
    "isThumbnail": true,
    "cid": "",
    "cidWithOutTags": "",
    "contentLocation": "",
    "download": "BN0gFmNTTOarHTn7bDrdaLxLQ-HmO36mmT8av0rwGMsO9XeBlK7OWBq4uiR5N3RkgjXBwwDtOcLBTPIx-354pFHsV2BigaNfpvFG7XlkFYyCsOwGQcNS2pR_U53ISNCnDV-bZYNjl6dc-XAPb71qOkkxn-XxWCtfqJl5ngPPQ67owcZUUfIv9ddSsGyX5PhMljxyMq6f_Cz6dp07Xeaex89ED35VTqyJe4C1MyAxq92fJlxBstcj7dM12YbRJzzWeS_B9t6g48mwh-0am6c28uxPAGYc_EP4C3VweITw7Q5uhTtNmycMksTu4CIVepYn",
    "folder": "INBOX",
    "uid": "22",
    "mimeIndex": "3",
    "framed": false
  }
];

var aAtt = oAtt.map(({fileName}) => [fileName]);

console.log(oAtt);
console.log(aAtt);

Solution 2:

No clue why .map is not working when used in the main code but I have ended up with a code below

var aAtt = newArray();

for(var i=0;i<oAtt.length;i++)
{
   aAtt[i] = newArray();

   aAtt[i].push(oAtt[i].fileName);
   aAtt[i].push(oAtt[i].mimeType);
   aAtt[i].push(oAtt[i].download);
}
