从列表列表创建 JSON 对象

Question

var data = [
    [
        "default_PROJECT",
        "Allow",
        "Connect",
        "Allow",
        "AddComment",
        "Allow",
        "Write",
        "Allow",
        "ViewComments",
        "Allow",
        "ExportData",
        "Allow",
        "ExportImage",
        "Allow",
        "ViewUnderlyingData",
        "Allow",
        "Read",
        "Allow",
        "ShareView",
        "Allow",
        "Filter"
    ],
    [
        "Allow",
        "ExportImage",
        "Allow",
        "Write",
        "Allow",
        "ViewComments",
        "Allow",
        "ShareView",
        "Allow",
        "Filter",
        "Allow",
        "ExportData",
        "Allow",
        "Connect",
        "Allow",
        "Read",
        "Allow",
        "ViewUnderlyingData",
        "Allow",
        "AddComment",
        "Allow",
        "ViewComments",
        "Deny",
        "ExportData",
        "Allow",
        "AddComment",
        "Deny",
        "Write",
        "Allow",
        "Read",
        "Deny",
        "ExportXml",
        "Deny",
        "ShareView",
        "Allow",
        "Connect",
        "Allow",
        "ChangeHierarchy",
        "Allow",
        "WebAuthoring",
        "Deny",
        "ViewUnderlyingData",
        "Deny",
        "Filter",
        "Deny",
        "ExportImage"
    ]
];


var newObj = {};

for(i=0; i<data.length; i++){
  //newObj['name'] = data[i][0];
  for(j=1; j<data[i].length;j++){
   newObj[data[i][j+1]] = data[i][j];
   document.write(data[i][j] + "----");
  }
}

document.write(JSON.stringify(newObj));

我正在尝试创建一个对象数组，其中每个对象都有“名称”，它是数组的第一个元素，然后是与“允许”或“拒绝”值关联的值。 例如我想得到：

{name: "default_PROJECT", connect: "Allow", AddComment: "Allow"} ... etc 

但是，某些数组具有重复的键，如果该值为 Deny，它将始终胜过先前的 Deny 值。

我开始迭代每个数组，然后尝试推送以下元素是否有键？ 我在写作轨道上吗？
