简化ajax对象

I have this function to write the inputs from a form to the database and i'm trying to simplify the data being passed by the ajax call to the php. Currently i have this function:

function writeDB(stage){
    var userData = $("#cacheDB").find("input").get();
    var ajaxData = []
    for (var n=0;n < userData.length; n++){
        item = {};
        item[userData[n].id] = userData[n].value;
        ajaxData.push(item);
    }

    $.ajax({
        url: "x.php",
        data: {ajaxData},
    });
}

Which sends out this object:

http://url.php?ajaxData[0][pageid]=1&ajaxData[1][input1]=John&ajaxData[2][input2]=Doe

I would like to send only the original data key, like:

http://url.php?[pageid]=1&[input1]=John&[input2]=Doe

Or

http://url.php?pageid=1&input1=John&input2=Doe

Is it posible? I've tried several methods and havn't found one suitable yet.

I would try to serialize the form instead of that for loop. It basically sends all input fields from your form as a JSON object to the server.

$.post('server.php', $('#theForm').serialize())

For larger form, HTTP POST method should be prefferd, you can send complicated object.

Hope its what you need.
