Iteration through a json object

[Gregor Kofler]

Nick S meinte:

Hi

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

What do you mean by "json object"?

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?

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.
