Question

really hope someone can help me with this, it’s driving me mad now…

I have a JSON object, with source:

[{"description":"General Accessories & Parts","id":"1"},{"description":"General Parts","id":"2"},{"description":"Parts","id":"3"}]

It’s an array returned from PHP, it used to look like this:

$array[0]['description']="General Accessories & Parts";
$array[0]['id']="1";

$array[1]['description']="General Parts";
$array[1]['id']="2";

etc...

So, I put the array into my JavaScript code:

obj=eval(ajax.responseText);

Now I need to loop over the description and id for each element in the array, I did try this:

for(var key in obj){
    if(!obj[key].hasOwnProperty(key)) continue;

    alert(obj[key]['description']);
}

The above code that I tried just echos [object Object],[object Object],[object Object] which is the 3 objects that I know are there.

Answer 1

Use

alert( obj[0].description );

and not

alert( obj[0]['description'] );
