Javascript accessing nested elements

Question

I have an array that kind of looks like this:

result = {
   akch_generation: 11841,
   akch_chassis: [{
    akch_sp: [{
        akch_faulted: false,
        akch_present: true,
        akch_fru: 'hc:///chassis=0/sp=0'
    }],
    akch_fan: [{
   ....
 }

And I want to get to the value of akch_faulted, but I can't figure out how.

I tried:

hardware.config().akch_chassis.akch_sp => result = undefined

hardware.config().akch_chassis.akch_sp.akch_faulted =>
error: illegal argument expression: "hardware.config().akch_chassis.akch_sp has
   no properties"

where hardware.config() is the command I run to get the result array.

I can only get as deep as akch_chassis...

Can anybody help me?

Yes! Thank you! It's a pitty you didn't reply where the answer section is... — Cristina

First of all result is not an array, is an object.

The problem is that yours nested objects are inside arrays so to access the property akch_faulted you need to write this:

result.akch_chassis[0].akch_sp[0].akch_faulted

already tried both of them, but it's not working: hardware.config().akch_chassis.akch_sp.akch_faulted error: illegal argument expression: "hardware.config().akch_chassis.akch_sp has no properties" hardware.config() gives me that object.

@Cristina could you post your whole code in a fiddle?

I'¡m afarid I can't. I run this command hardware.config() on a machine, and it displays this object (which is quite large).

I don't think that your comments are very useful ? By definition an array is an object, so there is not really "array notation" ? Did i said a mistake ?

I don't know if it was Saajan or you who answered first, but I'll give you the answer because you justified it well. Thanks for the solution.

This is the solution to get the value in javascript .

var myvalue = result.akch_chassis[0].akch_sp[0].akch_faulted

<script type="text/javascript" language="javascript" src="my.json"></script>
<script>
window.onload = function(){
var myvalue = result.akch_chassis[0].akch_sp[0].akch_faulted;
console.log(myvalue);
    }
</script>

This may be helpfull,

  for(var i=0;i<=result.akch_chassis.length;i++){
     for(var j=0;j<=result.akch_chassis[i].akch_sp.length;j++){
       var value=result.akch_chassis[i].akch_sp[j].akch_faulted;
     }
    }
