Good Day,I managed to add contracts and "resellers" (middlemen that have their own clients) to my installation of osTicket. There are 2 drop down menus (screenshot attached). The first dropdown menu allows an end-client to be chosen and the second dropdown has the contracts of the reseller. This is to help agents identify the ticket better as they can see what the user has chosen from the client side (screenshot 2). What I want is that when the ticket maker chooses an end-client, the second dropdown menu updates with only the contracts of the end-client selected. This works similiarly to the help topic dropdown using javascript. I know this isn't stackoverflow but can anyone explain to a javascript noob what goes on here:<select id="topicId" name="topicId" onchange="javascript: var data = $('', '#dynamic-form').serialize(); $.ajax( 'ajax.php/form/help-topic/' + this.value, { data: data, dataType: 'json', success: function(json) { $('#dynamic-form').empty().append(json.html); $(document.head).append(json.media); Thanks for any input.
