javascript - Combine jquery with php ajax request -

i'm having problem. i'm creating dynamic table jquery (the user insert value , creates table). in table have select tab pre-defined values coming table in database (mysql).

this code:

$(document).ready(function() {      $("#submit").click(function(e) {         $("#table").empty();        e.preventdefault();         if($("#numoflevels").val() >0)         {             var size = $("#numoflevels").val();             var str='';             str+='<table align="center" width="694" border="0" cellspacing="3"  cellpadding="0">';             str+='<tr><th style="width:auto" scope="col">level </th><th width="107">score</th><th width="58">game file</th><th width="80">catalog</th><th width="93">start date</th><th width="85">end date/th></tr>';               for(var = 0; i< size ; i++)             {                str+='<tr><td id="stage'+i+'" style="width:auto">level  '+(i+1)+'</td><td><span id="sprytextfield4"><input type="text"    name="score" id="score"/>';               str+='<span class="textfieldrequiredmsg">a value required.</span></span></td>';               str+='<td><input type="file" name="gamefile" id="gamefile" /></td>';               str+='<td><select multiple="multiple" name="catloglink" id="catloglink">';                 **here need enter php function**                str+='</select></td>';                str+='<td><input type="text" class="date" id="datepicker" ></td>';                str+='<td><input type="text" class="date" id="datepicker2" "></td>';                //str.find('input').datepicker();             }              //str+='</tr></table>';              $("#table").append(str);             var btn = '';             btn+='<tr><td width="192" colspan="2" align="center"><input type="submit" name="submit" id="submit" value="submit"/></td>';             btn+='<td width="309" colspan="4" align="center"><input type="reset" name="reset" id="clear" value="clear" /></td></tr></tr></table>';             $("#table tr:last").after(btn);           }         $(".date").click(function() {             $( ".date" ).datepicker();             $( ".date" ).datepicker();          });     }); }); 

and question how php code generates option list integarte javascript code.

• my php function retrieve values (names) don't send function data.
