如何使用 jquery 获取 User[keywords][] 的值？我试图变得像 console.log(User[keywords]);但它不起作用

{
  "User[firstName]": "",
  "User[lastName]": "",
  "User[city]": "",
  "User[countryCode]": "",
  "User[gender]": "",
  "User[userType]": "",
  "User[zip]": "",
  "User[email]": "",
  "User[age]": "",
  "User[fullAddress]": "",
  "CustomValue[11][fieldValue]": "",
  "CustomValue[5][fieldValue]": "",
  "CustomValue[1][fieldValue]": "",
  "CustomValue[6][fieldValue]": "",
  "CustomValue[7][fieldValue]": "",
  "CustomValue[2][fieldValue]": "",
  "CustomValue[8][fieldValue]": "",
  "CustomValue[9][fieldValue]": "",
  "CustomValue[4][fieldValue]": "",
  "CustomValue[10][fieldValue]": "",
  "CustomValue[3][fieldValue]": "",
  "User[teams][]": null,
  "": "",
  "User[keywords][]": [
    "52",
    "53",
    "54"
  ],
  "User[searchType]": "1",
  "User[keywordsExclude][]": null,
  "User[id]": "",
  "yt1": ""
}

【问题讨论】：

data["User[keywords][]"]; 这不适合你吗？
一旦你解决了眼前的问题，你应该考虑（如果它是你的）修复你的 JSON 的来源，使其更加理智。如果不是你的，去抱怨他们:)
您将这些数据存储在哪个变量中？
例如如果它是 var data 那么你可以试试 data.User[keywords]

标签： javascript jquery html json object

【解决方案1】：

如果这个json被赋值给变量obj：

console.log(obj['User[keywords][]']);

【解决方案2】：

我想您需要使用带有[] 方括号的数据来定位特定键：

var data = {
  "User[firstName]": "",
  "User[lastName]": "",
  "User[city]": "",
  "User[countryCode]": "",
  "User[gender]": "",
  "User[userType]": "",
  "User[zip]": "",
  "User[email]": "",
  "User[age]": "",
  "User[fullAddress]": "",
  "CustomValue[11][fieldValue]": "",
  "CustomValue[5][fieldValue]": "",
  "CustomValue[1][fieldValue]": "",
  "CustomValue[6][fieldValue]": "",
  "CustomValue[7][fieldValue]": "",
  "CustomValue[2][fieldValue]": "",
  "CustomValue[8][fieldValue]": "",
  "CustomValue[9][fieldValue]": "",
  "CustomValue[4][fieldValue]": "",
  "CustomValue[10][fieldValue]": "",
  "CustomValue[3][fieldValue]": "",
  "User[teams][]": null,
  "": "",
  "User[keywords][]": [
    "52",
    "53",
    "54"
  ],
  "User[searchType]": "1",
  "User[keywordsExclude][]": null,
  "User[id]": "",
  "yt1": ""
};
var pre = '<pre>'+ JSON.stringify(data["User[keywords][]"], 0, 0) +'</pre>'
document.write(pre)
