Reciving posted object node.js

Question

I've got an object:

var val = {username:'gilbertbw',password:'password',password2:'password',email:'email@email.com',firstname:'gilbert',lastname:'BW',test:true};

I run some validation against it and then post it to my node.js server:

console.log(
            $.ajax({
                type: 'POST',
                url: '/signup',
                data: val,
                success: function(){console.log('data posted')},
                dataType: "json"
            })
        );

On the server i have tryed just calling the object val:

console.log(val.username);

and pulling it from the post like I normally would:

val = req.param(val,null);
console.log(val.username);

But both times firebug spits out the 500 ISE:

    "{"error":{"message":"val is not defined","stack":"ReferenceError: val is not defined at exports.signup (C:\\Users\\Gilbert\\WebstormProjects\\NodeOfGames\\routes\\user.js:37:21)

If i just console.log(val); it prints null The line in question is when I try to log val.username to console. How do you recive a posted object in node.js?

Assigning `console.log` to `success` is invalid. You're assigning it the return value of `console.log`, not telling it to execute it. You'd need to use `success: function(){ console.log(..); }` — Brad Christie, Aug 08 '12 at 17:52
@BradChristie it logs 'data posted' to the log just fine thought — gilbertbw, Aug 08 '12 at 17:55
You're right, it will--be preemptive to the ajax being called, not actually on the success callback. — Brad Christie, Aug 08 '12 at 17:57
gilbert, just to further clarify the difference: http://jsfiddle.net/zaGCX/ — Brad Christie, Aug 08 '12 at 18:07
I suspect you are using Express, if so take a look at the accepted answer on this post http://stackoverflow.com/questions/4295782/node-js-extracting-post-data — Hector Correa, Aug 08 '12 at 18:26

val is a client-side variable. there is no way for the server to know you named this object "val".

data: val is just like:

data: {username:'gilbertbw',password:'password',password2:'password',email:'email@email.com',firstname:'gilbert',lastname:'BW',test:true}

so there is no val field for your server to find.

do this instead:

data: {
    "val": val
}

edit:

also, your line req.param(val,null); should be req.param("val",null);
or val = req.body.val;

the value of `val` is still `null` on the server, is there anything special I have to do to pick `val` up on the server? – gilbertbw Aug 08 '12 at 18:00
I still get `val is not defined` but with `console.log(req.body.val)` I get the expected responce in the server log. so `val = req.body.val` works fine for me – gilbertbw Aug 08 '12 at 18:39
glad it works. it'd be nice if you accept it as the correct answer. – EyalAr Aug 08 '12 at 19:20
