How to iterate JSON object using right side term-CodePudding

Lets say I have a JSON object like:

var objDBandIDs = {"vcFirstName":"enFN"
                    ,"vcSurName":"enSN"
                        ,"vcSex":["rdoM", "rdoF"]
                  ,"intEmployed":"enEmp"
                    ,"vcAddress":"enADR"};

In JavaScript I can iterate through this object using:

for( var strKey in objDBandIDs ) {
    var rightSide = objDBandIDs[strKey];
    ...
}

Where strKey is the label e.g. vcFirstName, rightSide would be enFN.

Is there a way to create a loop that instead of the left as an iterator, the right side is used to iterate through the JSON?

CodePudding user response：

You can't use the value as the key because values, unlike keys, may not be unique.

You can loop through just the values by looping through the result of Object.values:

for (const value of Object.values(objDBandIDs)) {
    // ...
}

Live Example:

const objDBandIDs = {
    "vcFirstName": "enFN",
    "vcSurName": "enSN",
    "vcSex": ["rdoM", "rdoF"],
    "intEmployed": "enEmp",
    "vcAddress": "enADR"
};
for (const value of Object.values(objDBandIDs)) {
    console.log(value);
}

Or you can loop through both using the result of Object.entries:

for (const [key, value] of Object.entries(objDBandIDs)) {
    // ...
}

Live Example:

const objDBandIDs = {
    "vcFirstName": "enFN",
    "vcSurName": "enSN",
    "vcSex": ["rdoM", "rdoF"],
    "intEmployed": "enEmp",
    "vcAddress": "enADR"
};
for (const [key, value] of Object.entries(objDBandIDs)) {
    console.log(key, value);
}

In both cases, you don't have to use a for..of loop, you can use any array looping mechanism (see my answer here for options).
