the error happens because the returned data from ajax request is empty. so you
can't access a variable on empty data.
make sure e holding data before printing variable ..

Set variable for JSON.
var variable = 'somevalue';
$.get(url, function(e){
console.log( e[0].variable );
});
How can i do something like this, i've tried almost everything but couldn't make it work.
-- The reason i wanna do that is that in the json output there are values like; a1, a2, a3 and i wanna get the value of a1 when its 10pm and get a2 when its 5am ect.
I get an error like : " Cannot read property 'variable' of undefined "
Thanks.

I am pretty sure that data is not empty

show output of console.log(e);

I think i accidentally used a wrong url, fixed it anyways. Here is how it looks like:
[
{
act: null,
id: "1",
a1: "1",
a2: "0",
a3: "0",
u1: "ax-1",
u2: "ax-2",
u3: "ax-3"
}
]
But still can't do what i wanna do

It's trying to look for a data called 'variable' from JSON.
i want something like;
var variable = 'u1';
console.log( e[0].variable );
So, i wanna see;
"ax-1"
Level 67
try console.log( e[0][variable] );
var key = 'u1';
var data = [
{
act: null,
id: "1",
a1: "1",
a2: "0",
a3: "0",
u1: "ax-1",
u2: "ax-2",
u3: "ax-3"
}
];
console.log(data[0][key]); // outputs "ax-1" for me
console.log(data[0].key); // undefined
