What is the best way to integrate a loop in JavaScript to retrieve values?

<script>
var data={ 
    Data: { 
        name: 'aaaa',
        number: '0003'
    },
    values: { 
        val: '-20.00',
        rate: '22047' 
    },
    user: [ '6|1|5', '10|1|15' ] 
};

console.log(data);
console.log(data.user.length);
for(var i=0;i<data.user.length;i++) {
    console.log(data.user[i]);
}
</script>

Here is the code showcasing a data structure with nested objects and an array. It logs the elements in the "user" array.

The contents of the "user" array are as follows: user: [ '6|1|5', '10|1|15' ]

However, there is a requirement to display the data in a different format:

  • userid - 6
  • roolno - 1
  • rank - 5


  • userid - 10

  • roolno - 1
  • rank - 15

If you need assistance in achieving this transformation, feel free to ask for help.

Answer №1

If you need a straightforward solution, consider using a basic map function like in this example on plunker:

data.user.map(function(x) { 
    var parts = x.split('|');
    return {
        userid: parts[0],
        roolno: parts[1],
        rank: parts[2]
    };
});

Executing the above code snippet would provide you with the following output:

[
    {
        userid: 1,
        roolno: 1,
        rank: 5
    },
    {
        userid: 10,
        roolno: 1,
        rank: 15
    },
]
