How to trigger jQuery change event in code

Question

I have a change event that is working fine but I need to get it to recurse   So I have a function that is triggered on change that will  change  other drop downs based on a class selector  notice  drop downS   there could be more than one   This proxy change does not trigger the function and so fails  How can i get it to work   Code    document  ready function          var activeDropBox   null          select drop-box   change function              var questionId     this  attr  questionId            var selectedAnswer     this  val            activeDropBox   this           alert this questionId              ajax                        type   POST               url  answerChangedActionUrl              data    questionId  questionId  selectedValue  selectedAnswer                success  function  data                    SetElementVisibility data ShowElement  questionId                  error  function  XMLHttpRequest  textStatus  errorThrown                    alert  XMLHttpRequest     XMLHttpRequest responseText                   alert  textStatus     textStatus                   alert  errorThrown     errorThrown                                          function SetElementVisibility visible  questionId               I would like each child to then trigger the change event                childOf    questionId  visible    show     hide    slow                Suggested code               childOf    questionId     select   trigger  change             if   visible                    childOf    questionId     select   attr  selectedIndex   0                       The suggestions so far seem to work  but as the change event triggers an ajax post it now seems to fail here  I m going to play around with it but that is something for another question I feel

The parameterless form of the change   method triggers a change event  You can write something like     document  ready function             yourInitialElementID   change function                Do something here                yourDropDownClass   change
