Question

The code:

---

function getDummyDetails(){
 var userDetailsMap = [];
 userDetailsMap.push({key:'APPCODE', value:'41'});
 userDetailsMap.push({key:'WORKERNUMBER', value:'1234567'});
 userDetailsMap.push({key:'ACCOUNTID', value:'DEVELOP'});
 userDetailsMap.push({key:'NAMEFIRST', value:'John'});
 userDetailsMap.push({key:'NAMELAST', value:'Developer'});

return userDetailsMap;

}

 function someOtherFunction () {

var userDetails = getDummyDetails();  
document.getElementById("userName").innerHTML = "User Name: " + userDetails[3].value + ", " + userDetails[4].value;

}

---

Here, it works fine but I can not use the array index here like userDetails[3].value. I was trying to do something like this

 userDetails["APPCODE"].value; // just a pseudo code

How can I index this array with that string values but not an integer?

Answer 1

You should create an object instead of an array. That way you’ll be able to access it via its key:

function getDummyDetails() {
    return {
        'APPCODE':'41',
        'WORKERNUMBER':'1234567',
        'ACCOUNTID':'DEVELOP',
        'NAMEFIRST':'John',
        'NAMELAST':'Developer'
    };
}

function someOtherFunction () {
    var userDetails = getDummyDetails();  
    userDetails["APPCODE"] // 41 - use it however you want...
}
