With no plug-ins  this can be easier without using as much jQuery  instead going slightly more old-school   var myOptions         val1    text1       val2    text2       each myOptions  function val  text            mySelect   append  new Option text val           If you want to specify whether or not the option a  is the default selected value  and b  should be selected now  you can pass in two more parameters       var defaultSelected   false      var nowSelected       true          mySelect   append  new Option text val defaultSelected nowSelected

Without using any extra plugins   var myOptions         val1    text1       val2    text2     var mySelect       mySelect      each myOptions  function val  text        mySelect append              lt option gt  lt  option gt    val val  html text               If you had lots of options  or this code needed to be run very frequently  then you should look into using a DocumentFragment instead of modifying the DOM many times unnecessarily  For only a handful of options  I d say it s not worth it though   ------------------------------- Added --------------------------------  DocumentFragment is good option for speed enhancement  but we cannot create option element using document createElement  option   since IE6 and IE7 are not supporting it   What we can do is  create a new select element and then append all options  Once loop is finished  append it to actual DOM object   var myOptions         val1    text1       val2    text2     var  select       lt select gt       each myOptions  function val  text         select append                  lt option gt  lt  option gt    val val  html text                     mySelect   append  select html       This way we ll modify DOM for only one time

I needed to add as many options to dropdowns as there were dropdowns on my page   So I used it in this way   function myAppender obj  value  text       obj append     lt option gt  lt  option gt    val value  html text         document  ready function         var counter   0      var builder   0         Get the number of dropdowns         id   ddlPosition      each function             counter                    Add the options for each dropdown         id   ddlPosition      each function             var myId   this id split      1               Add each option in a loop for the specific dropdown we are on         for  var i 0  i lt counter  i                  myAppender     id   ddlPosition   myId        i  i 1                         id   ddlPosition   myId       val builder           builder                  This dynamically set up dropdowns with values like 1 to n  and automatically selected the value for the order that dropdown was in  i e  2nd dropdown got  2  in the box  etc     It was ridiculous that I could not use this or this Object or   obj or anything like that in my 2nd  each    though --- I actually had to get the specific ID of that object and then grab and pass that whole object to my function before it would append   Fortunately the ID of my dropdown was separated by a     and I could grab it   I don t feel I should have had to  but it kept giving me jQuery exceptions otherwise   Something others struggling with what I was might enjoy knowing

Lets think your response is  successData   This contains a list which you need to add as options in a dropdown menu    success  function  successData    var sizeOfData   successData length  if  sizeOfData    0              NO DATA  throw an alert         alert   No Data Found      else         each successData  function val  text            mySelect append                  lt option gt  lt  option gt    val val  html text                           This would work for you
