How to make jQuery Autocomplete event handler work?

Question

I wrote code that could not use jQuery autocomplete to run the result function after the user selects something real (below).

As a result, I mean the result handler, a function that fires after a good selection occurs in the autocomplete plugin. Documented here .

In my case, I have a form that is really a table, where each row is the same, minus the unique identifiers of the fields: Item1, Qty1, Desc1, then Item2, Qty2, Desc2, etc. When the user enters the code Item1, the text Desc1 should display the English code of the selected item (Item2 → Desc2, etc.).

I used this code to find all the inputs of an Item and autocomplete it. For some reason, the result event handler does not fire. If you noticed, I hardcoded the selection of “Item1” because I did not understand how to select the appropriate Desc for the item, where Item1 → Desc1, Item2 → Desc2, etc.

I used MVC Url.Content only because I managed to get it to work. Someone used Url.Action, which, I think, is better, you just need to understand this.

Feel free to fix my use as needed, this is my first time with ASP.NET MVC / JQuery.

Thanks:)

Code:

$(document).ready(function(){

  $("input[id^='Item']").autocomplete( "<%= Url.Content("~/products/autocomplete")%>", {
  dataType: 'json',
  parse: function(data) {
      var rows = new Array();
      for( var i = 0; i<data.length; i++)
      {   rows[i] = {data:data[i], value:data[i].name, result:data[i].id }; }
      return rows;
  },
  formatItem: function(row, i, n) {
            return row.id + ' - ' + row.name;
        },
  selectFirst: true,
  //autoFill: true,
  minChars: 2,
  max: 30,
  autoFill: true,
  mustMatch: true,
  matchContains: false,
  scrollHeight: 100,
  width: 300,
  cacheLength: 1,
  scroll: true
  });

  $("Item1").result(function(event, data, formatted) {
      $("Desc1").html( !data ? "No match!" : "Selected: " + formatted);
  });
});

                return rows;
            },
            formatItem: function(row, i, n) {
                return row.id + ' - ' + row.name;
            },
            selectFirst: true,
            //autoFill: true,
            minChars: 2,
            max: 30,
            autoFill: true,
            mustMatch: true,
            matchContains: false,
            scrollHeight: 100,
            width: 300,
            cacheLength: 1,
            scroll: true
    }).result(function(event, data, formatted) {
        var n = $(this).attr("id").match(/\d+/);
        var b = $("span[id='Desc"+n+"']")
        b.html( !data ? "No match!" : "Selected: " + formatted);
    });
});
