populating a dropdown list based on the selection in another dropdown.

[Neelu Vibhuti]

In my JIRA gadget i have two dropdowns. I need to populate dropdownB based on the selection in dropdownA. Currently i have used dropdownA.onchange event and that event is not triggered.

where should I place the code so that the even is captured? config/view/script?

Currently I have placed this code in the script section, which is it working when I realod the page.

<script>                     
 chipNames.onchange = function(){   
                        		setTimeout(function(){}, 1);                        
                           		var selectedChip = chipNames.options[chipNames.selectedIndex].text;	
                           		if (selectedChip !== "" && selectedChip !== '-1') { 
                                  	boards.options.length = 0; 
                                  	AJS.$.ajax({
                                        url: "/rest/testresults-gadget/1.0/test-results-data/getOptions",
                                        data:{chips:selectedChip},
                                        dataType:"json",
                                        success:function(data){       	
			                             	var lists = data.boardNamesForTests;
			                             	var boardOptions = document.createElement('options');
			                             	boardOptions.text = " ";
			        			boardOptions.value = " ";  
			        			boards.add(new Option(boardOptions.value,0));
			        			for(var i = 0; i < lists.length; i++){			        						        						 
			        				boardOptions.text = lists[i].label;
			        				 boardOptions.value = lists[i].value;        						         						     
			        				boards.add(new Option(boardOptions.value,0));        						   
			        			}                              
                                        }
                                     });
                            	}
                           }

</script>

Have you tried using a cascading select list instead of a javascript bodge?

Neelu -

I have the similar requirement in our environment. Would you mind sharing the solution with us ?

Thanks

I suspect Neelu added a cascading select list via admin -> custom fields.
