You can achieve this with different methods   remember if an element is to be operated  better give it an id or class  rather than having it s parent element an id or class   Here  As the div has a class to target the select inside it  code will be     quot div id 100 select quot   val  quot val2 quot     or    div id 100  option value  quot val2 quot     prop  quot selected quot   true    If the class would have been given to select itself  code will be     quot  id 100 quot   val  quot val2 quot     or     id 100 option value val2    attr  selected   selected     or     id 100 option        removeAttr  selected        filter   value val1         attr  selected   true    To pass the value dynamically  code will be  valu  quot val2 quot      quot div id 100 select quot   val valu      quot div id 100  gt  select  gt  option value  quot    valu    quot   quot   prop  quot selected quot  true    If element is added through ajax  You will have to give  id  to your element and use window document getElementById else You will have to give  class  to your element and use window document getElementById You can also select value of select element by it s index number  If you have given ID to your select element  code will be  window document getElementById  select element   selectedIndex   4   Remember when you change the select value as said above  change method is not called  i e  if you have written code to do some stuff on change of select the above methods will change the select value but will not trigger the change  for to trigger the change function you have to add  change   at the end  so the code will be     quot  select id quot   val  quot val2 quot   change

I think the easiest way is selecting to set val    but you can check the following  See How to handle select and option tag in jQuery  for more details about options      div id 100  option value  val2     prop  selected   true       id 100   val  val2      Not optimised  but the following logic is also useful in some cases       id 100 option   each function         if   this  val       val2               this  prop  selected   true

There s no reason to overthink this  all you are doing is accessing and setting a property  That s it   Okay  so some basic dom  If you were doing this in straight JavaScript  it you would this   window document getElementById  my stuff   selectedIndex   4    But you re not doing it with straight JavaScript  you re doing it with jQuery  And in jQuery  you want to use the  prop   function to set a property  so you would do it like this       my stuff   prop  selectedIndex   4     Anyway  just make sure your id is unique  Otherwise  you ll be banging your head on the wall wondering why this didn t work

You must take it in mind the value you want to change dynamically  must be same as one present in the options you define in your HTML as it is case sensative  You can change your select box dynamically as follows       div YOUR ID   val VALUE CHANGED  change      value must present in options you selected otherwise it will not work

Use the change   event after selecting the value  From the docs      If the field loses focus without the contents having changed  the event is not triggered  To trigger the event manually  apply  change   without arguments        select id   val  val2   change      More information is at  change

You can select on any attribute and its value by using the attribute selector  attributename optionalvalue   so in your case you can select the option and set the selected attribute      div id 100  gt  select  gt  option value     value        prop  selected  true     Where value is the value you wish to select by   If you need to removed any prior selected values  as would be the case if this is used multiple times you d need to change it slightly so as to first remove the selected attribute     div id 100 option selected   prop  selected  false      div id 100 option value     value                 prop  selected  true

There seems to be an issue with select drop down controls not dynamically changing when the controls are dynamically created instead of being in a static HTML page   In jQuery this solution worked for me       editAddMake   val result data make id       editAddMake   selectmenu  refresh      Just as an addendum the first line of code without the second line  did actually work transparently in that  retrieving the selected index was correct after setting the index and if you actually clicked the control it would show the correct item but this didn t reflect in the top label of the control   Hope this helps
