I have a dropdown list (used html select and option) in my one view controller. when user select an item from it, the selected item should send to the next view's controller as a parameter and according to the value of the parameter, should do some sorting in xml and then send data to it's view. I have used jquery post. it pass the selected item's value to the next view's controller successefully. Then query is also success. Then in the second view it loops through.but finally null display.
