Create JavaScript object from string

I am trying to create a JavaScript function that creates an object using strings for a structure and populates it from DOM data.

For example, the following lines might look like this:

some.example.here = "hello"
some.example.there = "hi"
other.example = "heyo"

Which should create this object:

{
    some: {
        example: {
            here: "hello",
            there: "hi"
        },
    other: {
        example: "heyo
    }
}

The data, as said, comes from the DOM and is loaded into the code segment with the inscription "reading data into an object." The data loads fine, and the structure of the object is also fine tuned, but the data does not fit into the data field.

Here's the function code:

function getDataFromElement(element) {
  obj = {};
  $(element)
    .find("[data-value]")
    .each(function() {
      // create object node
      valueObj = {};
      currentValueObj = valueObj;
      $.each($(this).attr("data-value").split("."), function(i, objpath) {
        currentValueObj[objpath] = {};
        currentValueObj = currentValueObj[objpath];
      });

      // read data into object
      if($(this).is("[data-putvalue]") && $(this).attr("data-putvalue") != "html") {
        currentValueObj = $(this).attr($(this).attr("data-putvalue"));
      } else {
        currentValueObj = $(this).html();
      }

      console.log(currentValueObj);

      // combine with previous gathered data
      obj = $.extend(true, {}, obj, valueObj);
    });

  return obj;
}

Does anyone know what to do?

, ( , ): . name key value value

function fields2model( $elements, dataModel )
{
    $elements.each(function( ){
        var $el = $(this), 
            name = $el.attr('name'), 
            key, k, i, o, val
        ;

        key = name;

        val = $el.val() || '';

        k = key.split('.'); o = dataModel;
        while ( k.length )
        {
            i = k.shift( );
            if ( k.length ) 
            {
                if ( !o.hasOwnProperty( i ) ) o[ i ] = /^\d+$/.test( k[0] ) ? [ ] : { };
                o = o[ i ];
            }
            else 
            {
                o[ i ] = val;
            }
        }
    });
}

:

<input name="some.example.here" value="hello" />
<input name="some.example.there" value="hi" />


var model = {};
fields2model($('input,textarea,select'), model);

model:

model = {
some: {
    example: {
        here: "hello",
        there: "hi"
    }
};

:

var createObject = function(model, name, value) {
  var nameParts = name.split("."),
  currentObject = model;
  for (var i in nameParts) {
    var part = nameParts[i];
    if (i == nameParts.length-1) {
      currentObject[part] = value;
      break;
    }
    if (typeof currentObject[part] == "undefined") {
      currentObject[part] = {};
    }
    currentObject = currentObject[part];
  }
};

:

var model = {};
createObject(model, "some.example.here", "hello");
createObject(model, "some.example.there", "hi");
createObject(model, "other.example", "heyo");
