[jQuery] numeric formatter

[jQuery] numeric formatter


Hi,
Newbie learning jQuery. Failing miserably.
I am trying to implement http://decorplanit.com/plugin/ autoNumeric().
Automatically adds commas to numeric fields.
Got the plugin working fine.
Need code to copy contents of one text box to another (on blur) and
then remove commas by running $.fn.autoNumeric.Strip('id of the input
field that you want to remove the format');
This is how it has been done on the site but I just can’t work out.
jQuery(function($) {
    $('input.auto').blur(function(){
        var convertInput = '';
        if(this.name != 'decimal' && this.value != '' && this.id != 'ii1'){
            var    ndb = 'db' + this.id.charAt(2);
            var nid = 'ni' + this.id.charAt(2);
            convertInput = $.fn.autoNumeric.Strip(this.id);
            document.getElementById(ndb).value = convertInput;
            document.getElementById(nid).value = $.fn.autoNumeric.Format(nid,
convertInput);
        }
        if((this.id == 'ii1' || this.id == 'dpb') && this.value != ''){
            convertInput = $.fn.autoNumeric.Strip('ii1');
            var i = 1;
            for (i=1; i <= 9; i++){
                document.getElementById('ni'+i).value = $.fn.autoNumeric.Format
('ni'+i, convertInput);
            }
        }
    });
});
