Declared javascript object set to null values

Question

It's a simple question i have, I have a javascript object which is declared like this -

   adminID = {"Name": "","AdminId": ""}

At a later point in the code i assign it some values -

  adminID = {"Name": "xyzabc","AdminId": "123123"}

Now, how can i assign the values back to null so my object looks like

  adminID = {"Name": "","AdminId": ""}

Is there a smarter way to do it or should i specify all the keys to null individually.

Cheers!

Do you want null as in your description or "" (empty string) as in your code sample? — nnnnnn

You'd do it like this in JavaScript:

for(var p in adminID)
    if(adminID.hasOwnProperty(p))
        adminID[p] = '';

Ruby version

Here is one way

adminID.each {|k,v| adminID[k] = ""}

Here is another

adminID.keys.each {|k| adminID[k] = ""}

Javascript version

for(var i in adminID) { adminID[i] = ""}

Thanks! Sorry i just realized i had implemented that in a javascript. How can I achieve the same in javascript.

I added a js version of my code as well. I think @mu's version is more robust.

That's why I gave you an up-vote and went to the OP for some clarification. You answered what they asked rather than what they meant, or something like that. Hooray for confusion!
