Extend an object using jquery

I have 2 divs where 1st div has 2 text boxes while the other div has several text boxes
Manually I am adding the textbox name and value to an object for the 1st div. But for second div I am getting all the textbox names and values using jQuery to avoid having a large block of similar code.

var obj = {};
obj.LayoutName = document.getElementById("aSL_stripLayoutName").value;
obj.Version = document.getElementById("aSL_StripLayoutVersion").value;

Then I want to extend the object and add all textbox names and values to 'obj' using extend,

$("#aSL_stripLayoutDetails-UpperSection :text").each(function(){//TODO});

What I have tried:

I have tried the below and an example is working adding a known textbox name 'StripDimX' and value '333'

$.extend(obj, {StripDimX : "333"});

If I want to get the name I use this inside the below function

document.getElementById(this.id).name

and this for the value

document.getElementById(this.id).value

But my problem is how to add the names and values to the object?

$("#aSL_stripLayoutDetails-UpperSection :text").each(function(){
   //$.extend(obj, {StripDimX : "333"});
});

This of course does not work:

$("#aSL_stripLayoutDetails-UpperSection :text").each(function(){
 $.extend(obj, {document.getElementById(this.id).name:             document.getElementById(this.id).value});
});

Then I tried the below and name is ok, but the value is being added as an array:

$("#aSL_stripLayoutDetails-UpperSection :text").each(function(){
        var n = document.getElementById(this.id).name;
        var v = document.getElementById(this.id).value;
          $.extend(obj, { [n] : [v]});
});

        var tempObj = new createObject(n,v);
