node.js - 如何删除双引号

Question

如何从数据中删除双引号

[{"label":"Ravi Kanti","data":"[314,444]"},{"label":"Amit prakash","data":"[78]"},{"label":"Roshan Kumar","data":"[215,80,165]"}]

由于数据值在双引号内，即“[314,444]”如何删除双引号

Answer 1

没什么大不了的，因为它只是嵌入了 JSON：

data = [{"label":"Ravi Kanti","data":"[314,444]"},{"label":"Amit prakash","data":"[78]"},{"label":"Roshan Kumar","data":"[215,80,165]"}]

data.forEach(entry => {
  entry.data = JSON.parse(entry.data)
});

JSON.stringify(data)
// [{"label":"Ravi Kanti","data":[314,444]},{"label":"Amit prakash","data":[78]},{"label":"Roshan Kumar","data":[215,80,165]}]

Answer 2

在 Javascript 中，你可以这样尝试：

var str = '[{"label":"Ravi Kanti","data":"[314,444]"},{"label":"Amit prakash","data":"[78]"},{"label":"Roshan Kumar","data":"[215,80,165]"}]';

var arr = JSON.parse(str, function (key, value) {
  if (key === "data") {
    return JSON.parse(value);
  } else {
    return value;
  }
});

console.log(arr);
