SharePoint PreSaveAction helps for actions before saving an item

If you’re customizing SharePoint listforms or SharePoint forms you have normally a save or cancel button. If you want to have a pre-action for the save button, that means there should something happen before the item will be saved if the user clicks on the save button, you can use the javascript function PreSaveAction(). This function takes place before saving the item.

I my customer project i need this function for the following scenario. The user has to choose a value from dropdown list. If the selected item from dropdown has a special value, the user should get a message, that informs him about a special situation and that he should confirm to proceed.
