如何在javascript中检索键值 [英] How to retrieve key values in javascript

问题描述

我的json数据格式如下：

My json data format is like below:

"INFO" : {
    "DETAILS" : {
        "EMP" : {
             "amount": " 12185",
             "job": "GAPA",
             "month": "JANUARY",
             "year": "2010"
         }
     }
},

我在上面的json中获取了键的值。获得关键值后，我想得到地图（即）信息。

I am getting the values of keys in the above json. After getting the key values I want to get the map (i.e) INFO.

现在，我想为提交等按钮设置id或属性值为INFO。

Now, I want to set the id or a attribute value as "INFO" for a button like submit.

我该怎么办？

推荐答案

目前还不完全清楚你在问什么，但如果你想循环通过这些项目，你可以做到这一点。

It's not entirely clear what you're asking, but if you want to loop through the items, you can do this.

var json = '{"INFO" : {"DETAILS" : {"EMP" : {"amount": " 12185","job": "GAPA","month": "JANUARY","year": "2010"}}}}',
  i;

json = JSON.parse(json);

for (i in json.INFO.DETAILS.EMP) {

  // always check for own properties when looping through an object
  if (json.INFO.DETAILS.EMP.hasOwnProperty(i)) {
    console.log('key: %s, value: %s', i, json.INFO.DETAILS.EMP[i]);
  }
}
