JavaScript code I'm starting with:
function doSomething(url) {      $.ajax({       type: "GET",         url: url,         dataType: "xml",         success: rssToTarget      });   }       Pattern I would like to use:
//where elem is the target that should receive new items via DOM (appendChild) function doSomething(url, elem) {    $.ajax({       type: "GET",       url: url,       dataType: "xml",       success: rssToTarget(elem)    }); }     I don't think I can get the callback to work this way, right? What is the proper pattern? I don't want to use global variables necessarily to temporarily hold the elem or elem name.
Like this...
function doSomething(url, elem) {   $.ajax({      type: "GET",      url: url,      dataType: "xml",      success: function(xml) {        rssToTarget(xml, elem);      }   }); }   Answer to your comment: Does use of anonymous functions affect performance?
