javascript - 通过key获取json数据

Question

  const username = 'merMan';

  fetch("./datz.json")
    .then(response => response.text())
    .then((response) => {
        console.log(response);

    })

我的数据响应如下所示，仍然很难简单地获取用户特定的数据。我的响应数据输出如下。我尝试过使用 find，但总是返回 find is not a function，response[username] 也不起作用。

[{"mermAn":{"baseMapId":"459cc334740944d38580455a0a777a24","customBaseMap":"","zoomn":"5","orient":"0","centLon":"-93.69999999999843","centLat":"38.64999999999935"},
{"catWoman":{"baseMapId":"459cc334740944d38580455a0a777a24","customBaseMap":"","zoomn":"5","orient":"0","centLon":"-93.69999999999843","centLat":"38.64999999999935"},
{"Riddler":{"baseMapId":"459cc334740944d38580455a0a777a24","customBaseMap":"","zoomn":"5","orient":"0","centLon":"-93.69999999999843","centLat":"38.64999999999935"}}]

您需要在 response.text() 之后解析响应，例如:

fetch("./datz.json")
    .then(response => response.text())
    .then((response) => {
        try {
          const parsedArray = JSON.parse(response);

          console.log(parsedArray);
        } catch (error) {
          // response could not be parsed
        }
    })
