javascript - 如何获取json结构中的键的单个特定值？

我正在做一些运动，例如：

var jsonres;
jsonres = JSON.stringify(jsonObjectArray);
alert(jsonvals); // getting the below json structure

jsonres = {
    "key01": [10, "Key01 Description"],
    "key02": [false, "It's a false value"],
    "key03": [null, "Testing Null"],
    "key04": ["tests", "Another Test Value"],
    "key05": [[25, 50], "Some testing values"]
}

但我需要这样：

jsonres = {
    "key01": 10,
    "key02": false,
    "key03": null,
    "key04": "tests",
    "key05": [25,50]
}

我怎么能像上面的结构（意味着我只需要单个值，不需要各个键的第二个值/多个值）？请帮助我，在此先感谢。

最佳答案

var jsonres = {
    "key01": [10, "Key01 Description"],
    "key02": [false, "It's a false value"],
    "key03": [null, "Testing Null"],
    "key04": ["tests", "Another Test Value"],
    "key05": [[25, 50], "Some testing values"]
}

for(var key in jsonres){
   if(jsonres.hasOwnProperty(key)){
      jsonres[key] = jsonres[key][0];
   }
}

console.log(jsonres)
