带有方括号的JSON数组键

Question

我有一个JSON数组，该数组的键中带有方括号，例如““ {

{
  "msg":"OK",
  "data":[
    {
      "nls!type":"NCR",
      "current":"Assign",
      "physicalid":"0FFE0001000009FC5BD6805C00001352",
      "attribute[custTitle]":"Title",
      "name":"181002",
      "description":""
    }
  ]
}

我如何在javascript中获得"attribute[custTitle]"的值

当我尝试获取arrData[i].attribute[custTitle]时，由于未定义custTitle，它会返回错误，我可以通过相同的方式获取其他值。

Answer 1

尝试

const response = {
  "msg":"OK",
  "data":[
    {
      "nls!type":"NCR",
      "current":"Assign",
      "physicalid":"0FFE0001000009FC5BD6805C00001352",
      "attribute[custTitle]":"Title",
      "name":"181002",
      "description":""
    }
  ]
};

console.log(response.data[0]['attribute[custTitle]']);
