My JSON:

const tests = {
"test 1": {
    "name": "name 1",
    "last name": "prid",
},
"test 2": {
    "name": "name 1",
    "last name": "prid",
},
};

And this is my code:

const obj = {
    enterSom: function(name) {
        console.log(name)
    },

    enterName: function(tests) {
        for (test in tests) {
            let name = test["name"]

            this.enterSom(name)
        }
    },
};

The results:

undefined
undefined

When I create something like this:

// first case
console.log(tests["test 1"]["name"])
// result -> name 1

// second case
for (test in tests) {
    console.log(test)
}
// result -> test 1
// result -> test 2

And when I extract the loop from my code:

for (test in tests) {
    console.log(test["name"])
}
// result -> undefined
// result -> undefined

How can I get the JSON data when the data are nested like this?

CodePudding user response：

Your code is fine. Only for (key in obj) and not for (value in obj)

const tests = {
  "test 1": {
    "name": "name 1",
    "last name": "prid",
  },
  "test 2": {
    "name": "name 2",
    "last name": "prid",
  },
};


const obj = {
  enterSom: function(name) {
    console.log(name)
  },

  enterName: function(tests) {
    for (test in tests) {
      let name = tests[test]["name"]

      this.enterSom(name)
    }
  },
};

obj.enterName(tests);
