Passing JSON object through loop to be used in jQuery Dialog

I'm wondering if there is a better (cleaner?) method than my current implementation. I'm currently encoding a PHP SimpleXMLObject (USPS Tracking API) to JSON and looping through said JSON object via JavaScript to operate the front-end.

Examples from my current implementation below:

Function to display dialog implemented anonymously outside of .ready():

var moreInfo_popup = function(i) {
$('#moreinfo'+i).dialog({
        modal:false,
        autoOpen:false,
        height:555,
        title: 'Detailed View',
        width:500,
        draggable:false,
        buttons: {
            Ok: function(){
                $(this).dialog("close");
        }
    }
    });

        $('#moreinfo'+i).dialog('open');

        }

Main loop for displaying Tracking ID, Most Recent Event, and Mail Class for each API response- I'm currently generating a content div appended to #modal_container, then calling moreInfo_popup() inline via <input onClick="">:

for(var key in obj) {
                    if(obj.hasOwnProperty(key)) {
                    if(key % 2 === 0) {
                    $('#page-nav').append("<div id=\"results_table\"><table class=\"data_table\"id=\"data_table_id\"border=\"0\"width=\"60%\"align=\"center\"><tr><td align=center width=20%>"+obj[key].TrackInfo.Attributes.ID+"</td><td align=\"center\"width=\"35%\">"+obj[key].TrackInfo.StatusSummary+"</td><td align=\"center\"width=\"20%\">"+obj[key].TrackInfo.Class+"</td><td align=\"center\"><input type=\"button\"class=\"moreInfo\"value=\"Detail\"id=\"_buttonMoreInfo\"onClick=\"moreInfo_popup("+key+")\"></td></tr></table></div>");

                    $('#modal_container').append("<div id=\"moreinfo" + key + "\"><table><tr><td>" + obj[key].TrackInfo.Attributes.ID +"</td></tr></table>").hide();
                  }
                else {
                  $('#page-nav').append("<div id=\"results_table\"><table class=\"data_table_even\" id=\"data_table_id\" border=0 width=60% align=center><tr><td align=center width=20%>" 
                                      + obj[key].TrackInfo.Attributes.ID + "</td><td align=center width=35%>" + obj[key].TrackInfo.StatusSummary + "</td><td align=center width=20%>" 
                                      + obj[key].TrackInfo.Class + "</td><td align=\"center\"><input type=\"button\" value=\"Detail\" class=\"moreInfo\" id=\"_buttonMoreInfo\"onClick=\"moreInfo_popup("+key+")\"></td></tr></table></div>");

                  $('#modal_container').append("<div id=\"moreinfo" + key + "\"><table><tr><td>" + obj[key].TrackInfo.Attributes.ID +"</td></tr><tr><td> <button>OK</button></td></tr></table>");


                }

            }

      $("#page-nav td:contains('undefined')").html("Invalid");    
  }

As I'm sure you can see, this feels like an incredibly tedious way of accomplishing the desired outcome, to which there is surely a better alternative. As a newcomer to JavaScript/jQuery, I've done plenty of searching on this subject, but haven't really understood much of what I found, if indeed I was asking the right questions in the first place.
