How to access @rid, @type etc in client JS

[Gaurav Dhiman]

Issue - @ character is not a valid character in JavaScript identifier (variable, function name etc), then how to refer @rid in returned JSON from OrientDB ?

Details:

When I get the JSON response from OrientDB and I try to show the @rid, @type etc in app, I get JS error

In client http response function, below is the wrong syntax

function httpResponse (data, status) {

   alert(data.result[0].@rid);                     // how to refer @rid here ??

}

Hi,
Use ['@rid']

@Lvc, as suggested by you, when I use ['@rid']

alert(data.result[0].['@rid']);

Chrome debugger says "Uncaught SyntaxError: Unexpected string"

Any other suggestions. I am sure many other OrientDB users must have faced this basic thing while consuming OrientDB generated JSON in their app.

Can not we configure OrientDB to use some other character in place of @ and # while throwing out JSON to client ?

Regards,

Gaurav

The dot notation is the shortcut of the array access. Just use data.result[0]['@rid'] in this case.

Thanks Julien, it worked.

Can we refer deep level objects in this manner, using array notation [] in place of dot notation ?

Thanks for your help !

Gaurav

Yes, you can. These two notations are exactly the same : a.b.c.d.e.f <=> a['b'].c['d']['e'].f

The array notation is very usefull when you have dynamic keys (arr[dynamicKey]) or complex keys (arr['Hey dude !'])
