Please describe how I can return the boolean value from the js function below to the caller in the onclick event handler. It's not working this way.

<script type="text/javascript"> function showWarning() { var myVar; var callback = function(result) { if (result == null || result == '') { myVar = confirm('No interchange programs were assigned to rate category. Are you sure you want to proceed with saving?'); alert('myVar = '+myVar); //return myVar; <-- is it legal to return from here and will it get back to the caller in the onclick handler? } else { myVar = true; } }; Seam.Remoting.getContext().setConversationId( #{conversation.id} ); Seam.Component.getInstance("merchantBillingGroupEditorUI").getSelectedRateCategory(callback); alert('myVar 2nd time = '+myVar); return myVar; /*var result = Seam.Component.getInstance("merchantBillingGroupEditorUI").getSelectedRateCategory(); alert('result = '+result); if (result == null || result == '') { return confirm('No interchange programs were assigned to rate category. Are you sure you want to proceed with saving?'); }*/ }
