Only change the DOM once     var listitems         each temp  function key  value       listitems      lt option value     key     gt     value     lt  option gt         select append listitems

I would do something like this     each temp function key  value          select append   lt option value     key     gt     value     lt  option gt           JSON structure would be appreciated  At first you can experiment with find  element   - it depends on JSON

A solution is to create your own jquery plugin that take the json map and populate the select with it      function                  fn fillValues   function options             var settings     extend                datas   null                complete   null              options             this each  function                var datas   settings datas              if datas   null                      this  empty                    for var key in datas                         this  append   lt option value    key     gt   datas key    lt  option gt                                                 if   isFunction settings complete                    settings complete call this                                       jQuery      You can call it by doing this        select   fillValues  datas your map       The advantages is that anywhere you will face the same problem you just call              fillValues  datas your map       Et voila    You can add functions in your plugin as you like

I just used the javascript console in Chrome to do this  I replaced some of your stuff with placeholders   var temp    one    two    three         temp      alert options   var  select       lt select gt           down                             select find  option   remove                                each temp  function key  value                          lt option gt    val key  text value  appendTo  select       console log  select html       Output       lt option value  0  one lt  option  lt option value  1  two lt  option  lt option value  2  three lt  option    However it looks like your json is probably actually a string because the following will end up doing what you describe   So make your JSON actual JSON not a string   var temp     one    two    three          temp      alert options   var  select       lt select gt           down                             select find  option   remove                                each temp  function key  value                          lt option gt    val key  text value  appendTo  select       console log  select html
