  Not retrieving the correct id

  Apr 24, 2012 03:42 PM|LINK

  Hello All,
  
  I have this function to search person info. When I click a search button, it retrieves
  some info. and adds to a table as rows. I have the function to click "trs" and then
  do something with it which calls "SetDevMember" function. I need to pass the id attached to that
  particular row to this function. But right now it is always retrieving the last row's id.
  
  function GetPersonInfo()
      {
          $.ajax({
                  type: 'GET',
                  url: "@Url.Action("GetPersonDetails", "Emp")" +  "?first=" +  $("#FirstName").val() +  "&last=" +  $("#LastName").val() ,
                  success: function(responseobj, status) {
                                  if (responseobj.length > 10) {
                                         $("#SearchResults").find("tr:gt(0)").remove();
                                          $('#SearchResults').show();
                                          var nextRow=$("<tr><td>"+ "Search retrieved more than 10 results. Please narrow your search" + "</td></tr>");
                                           $('#SearchResults tr:last').after(nextRow);
                                  }
                                  else
                                  {
                                      $("#SearchResults").find("tr:gt(0)").remove();
                                      for(var i =0;i < responseobj.length;++i) {
                                          var item = responseobj[i];
                                          $('#SearchResults').show();
                                          var nextRow=$("<tr><td>"+ "Name: " + item.FirstName + " " +  item.LastName + "</br>" + "Email: " +  item.EmailAddress  + "</td></tr>");
                                          $('#SearchResults tr:last').after(nextRow);
                                          $('#SearchResults tr').addClass('SearchResultItem ui-corner-all');
                                          $('#SearchResults tr').hover(function () {
                                                  $(this).addClass('ui-state-hover');
                                                  }, function () {
                                                      $(this).removeClass('ui-state-hover');
                                                  }).click(function () {
                                                      var name = item.FirstName + " " + item.LastName;
                                                      SetDevMember(item.PersonId, name);
                                          });
                                          };
                                        }
                                    },
                  error: function()
                         {
                              console.log("Bad");
                         }
                 });
         
      }

  The value of item at the time you click is always the last one, which is what you are seeing.  This is the sequence of events:

  The for-loop executes, doing it's thing.  After the for-loop finishes executing, item is now pointing at the last item.

  Then you click, and pass the value of item.

  This should get you your current item:

  .click(function () {
  var ndx = $(this).prevAll().length; //count the number of TRs before us
  var myitem = responseobj[ndx];
  var name = myitem.FirstName + " " + myitem.LastName;
  SetDevMember(myitem.PersonId, name);
  })

  It might be off by one index, so you might have to subtract one from ndx.  I didn't look that closely, but that will put you on the right track.

  Thank you for explaining me. That did work. I had to substract one though...
