Fiddle with Scholar - Override the default behavior of the 'Cite' link and instead search for the APA reference and write the results to the console

overrideScholarCiteLink.js

function extractCite(elem, exporterName)
{
   var apa, exporter;
   var results = elem.querySelectorAll('.gs_citf'); 
   var exporters = elem.querySelectorAll('a.gs_citi');

   // Find the APA row
   for(var i = 0; i < results.length; i++) {
      if(results[i].textContent == 'APA')
         apa = results[i];
   }

   // Find the exporter link
   for(var i = 0; i < exporters.length; i++) {
      if(exporters[i].textContent.indexOf(exporterName) != -1)
         exporter = exporters[i];
   }

   if(exporter)
   {
      gs_ajax(exporter.getAttribute('href'), function(status, results){
         console.log('ExporterResults', results);
       });
   }

   // Return the cite
   return apa.nextSibling.querySelector('div').textContent;
}

if(typeof(jsAjaxOriginal) == "undefined") {
   // Store the original reference
   window['jsOcitOriginal'] = gs_ocit;

   // wrap original
   function gs_ocit(e, id) {
      var url = '/scholar?q\x3dinfo:{id}:scholar.google.com/\x26output\x3dcite\x26hl\x3den\x26as_sdt\x3d0,5\x26scfhb\x3d1'.replace('{id}',id);
      gs_ajax(url, function(status, results){
         
         var temp = document.createElement('div');
         temp.innerHTML = results;

         console.log(extractCite(temp, 'RefMan'));
       });
   }
}
