Iteration through a json object

[Nick S]

Hi

Is there anyway to iterate through a json object and retrieve the name
of the property as well as the value.

For exampe. Imagine this object

{
title: '1',
bedrooms: '2',
bathrooms: '3',
description: '4',
country: '5',
location: '6',
price: '7',
}

I want to loop through it and have a variable that holds title, then
bedrooms then bathrooms.... as well as one that holds 1 then 2 then
3... respectively.

Is that possible?

Thanks

What do you mean by "json object"?

}

You are looking for "for ... in". Mind the possible problems with
(augmented) prototypes, though.

err, ok, just forget my crappy grasp of the terminology for a second.
I've outlined the problem pretty clearly. I do use "for...in" but I
can't get to the name of each item. (And if that's not clear I mean
the thing on the left of the colon) :)

Thanks

Lets see:

var obj = { ... }, p;
for(p in obj) {
window.alert(obj[p]);
};

Please answer: What is the value of p?

Thanks. yes, this is what I do, however, I don't just want the value,
I also want the name of the property.

Jeez! The value of p *is* the name of the property. obj[p] gives you the
value of the property p.
