How to access a specific index of an array in node.js

Question

I want to get only the AID from the solution now i am getting. I tried rows[0] but was not successful.

Code:

console.log('The solution is: ', rows);

Output:

The solution is:
[ { AID: 6520,
    DID: 113071,
    TITLE: 'First Knight',
    DATE: '7/7/1995',
    SCORE: 89 } ]

Use rows[0]["AID"] to access the AID property.

rows[0].AID is a usually preferred notation

Let's understand your overall data structure here:

var rows = [ 
 { 
    AID: 6520,
    DID: 113071,
    TITLE: 'First Knight',
    DATE: '7/7/1995',
    SCORE: 89 
  } 
];

The variable rows is an array of objects. Thus rows[n] gets you a specified object in that array and therefore rows[0] is the first object in the array which would be:

 { 
    AID: 6520,
    DID: 113071,
    TITLE: 'First Knight',
    DATE: '7/7/1995',
    SCORE: 89 
  }

So, now you want to access the AID property in that object so you can just do:

rows[0].AID

And, here's a working snippet demo:

var rows = [ 
 { 
    AID: 6520,
    DID: 113071,
    TITLE: 'First Knight',
    DATE: '7/7/1995',
    SCORE: 89 
  } 
];

document.write(rows[0].AID);
