Question

The following statement is used because the method in question (refreshPartyList()) may not always be defined.

try {
  parent.document.getElementById("myId").contentWindow.refreshPartyList(param1, param2);
}catch(e){}

Currently using the above approach and it is working fine, but is there a better alternative?

Answer 1

var e = parent.document.getElementById("myId").contentWindow;
if(e.refreshPartyList)
  e.refreshPartyList(param1, param2);
