C＃下拉菜单选择的索引已更改触发jQuery脚本

Question

I am trying to trigger jquery function when dropdown index is changed. Since the dropdown is making a postback I have accordion group in which one group is expanded. On postback I want to preserve that accordion group and leave it open. I want to trigger the jquery script and expand the same accordion group. On page load I have this script:

  jQuery(document).ready(function () {
              var accordionId = getParameterByName("policy");           
              $('#' + accordionId).collapse('show');
          });     

It checks if there is querystring parameter 'policy' and according to that value the correct accordion is expanded. Now since with dropdown postback I don't want to do whole response redirect since I'll lose all the data and selected dropdown values I want to trigger jquery script as well which will open the appropriate accordion.

You can see the accordion markup at this link: twitter bootstrap accordion expand by querystring parameter in asp.net

Thanks in advance, Laziale

Use the accordion's activate event to save the current open panel to a cookie. Then after a postback, you can read the cookie value and set the open accordion panel appropriately.
