Mutilple javascript variable iterations with jquery

Question

i have a form and would like to give users the ability to duplicate a group of fields as many times as necessary. With one group it iterates correctly but when I add a second group the "current" variable iterates collectively instead of being unique to each group... i tried changing all of the "current" to "newFieldset.current" but that returns NAN... any ideas?

<script type="text/javascript">
$(document).ready(function() {
var current = 0;
    //Add New Fieldset with Button
    var newFieldset = {
        init: function(groupIndex) {
            current++;
            $newPerson= $("#Template"+groupIndex).clone(true);
            $newPerson.children("p").children("label").each(function(i) {
                var $currentElem= $(this);
                $currentElem.attr("for",$currentElem.attr("for")+current);
            });
            $newPerson.children("p").children("input").each(function(i) {
                var $currentElem= $(this);
                $currentElem.attr("name",$currentElem.attr("name")+current);
                $currentElem.attr("value",$currentElem.attr("value")+groupIndex+current);
                $currentElem.attr("id",$currentElem.attr("id")+current);
            });

            $newPerson.appendTo("#mainField"+groupIndex);
            $newPerson.removeClass("hideElement");
        },
        currentID: null,
        obj: null
    };
    $(".addButton").each(function() {
        $(this).click(function() {
            var groupIndex = $(this).attr("title");
            //newFieldset.obj = this;
            //var fieldIndex = $(this).attr("class");
            newFieldset.init(groupIndex);
        });
    });

    console.log('r');
});

Attach the value to the element with the jQuery data method. Increment it on click, and then pass it to the newFieldset.init method as the second param. Voila!

$(document).ready(function() {
    //Add New Fieldset with Button
    var newFieldset = {
        init: function(groupIndex,current) {
                $newPerson= $("#Template"+groupIndex).clone(true);
                $newPerson.children("p").children("label").each(function(i) {
                        var $currentElem= $(this);
                        $currentElem.attr("for",$currentElem.attr("for")+current);
                });
                $newPerson.children("p").children("input").each(function(i) {
                        var $currentElem= $(this);
                        $currentElem.attr("name",$currentElem.attr("name")+current);
                        $currentElem.attr("value",$currentElem.attr("value")+groupIndex+current);
                        $currentElem.attr("id",$currentElem.attr("id")+current);
                });

                $newPerson.appendTo("#mainField"+groupIndex);
                $newPerson.removeClass("hideElement");
        },
        currentID: null,
        obj: null
    };
    $(".addButton").click(function() {
        var groupIndex = $(this).attr("title");
        var current = $(this).data('current');
        $(this).data('current',++current);
        //newFieldset.obj = this;
        //var fieldIndex = $(this).attr("class");
        newFieldset.init(groupIndex,current);
    }).data('current',0);

    console.log('r');
});

Happy jquery-ing to you sir.

if you dont make the current variable global it will should work. try this:

var newFieldset = { 
                  current: 0,
                  init: function() {
                      this.current++; 
                      //rest of init code
                  },
                  //all your other fieldset code here
};
/* all other code */

EDIT: After re-reading the question, I would take a completely different approach to what you're trying to achieve. The above code will still exhibit the same behavior for you. If the question hasn't been successfully answered I'll do a bigger writeup when i get home.

I would do something like that:

...
var currents = {};
var newFieldset = {
    init: function(groupIndex) {
        var current = 0;
        if (currents[groupIndex]) {
            current = currents[groupIndex];
        }
        ++current;
        currents[groupIndex] = current;
...
