MVC jQuery的自動完成多個值首次工作只

Question

我想在我的MVC項目自動完成多個值，但它自動完成對第一個值和第二沒有發生
我的視圖代碼：

@Html.TextBox("SentUsers", "", new { @class = "text-box"}) 
@Html.Hidden("UsersId") 

Java腳本代碼：

<script type="text/javascript"> 
var customData = null; 
var userId; 
$(function() { 
    $("#SentUsers") 
     .bind("keydown", function (event) { 
      if (event.keyCode === $.ui.keyCode.TAB && 
      $(this).data("ui-autocomplete").menu.active) { 
       event.preventDefault(); 
      } 
     }) 
     .autocomplete({ 
      minLength: 2, 
      source: function (request, response) { 
       $.ajax({ 
        url: "/Ajax/AutoCompleteUsers", 
        type: "POST", 
        dataType: "json", 
        data: { term: request.term }, 
        success: function (data) { 
         alert(data); 
         customData = $.map(data, function (item) { 
          userId = item.UserId; 
          return { label: item.Name + "(" + item.Email + ")", value: item.Name } 
         }); 
         response(customData, extractLast(request.term)) 
        } 
       }) 
      }, 
      focus: function() { 
       // prevent value inserted on focus 
       return false; 
      }, 
      select: function (event, ui) { 
       var usersIdVal = $("#UsersId").val(); 
       usersIdVal += ", " + userId; 
       $("#UsersId").val(usersIdVal) 

       var terms = split(this.value); 
       // remove the current input 
       terms.pop(); 
       // add the selected item 
       terms.push(ui.item.value); 
       // add placeholder to get the comma-and-space at the end 
       terms.push(""); 
       this.value = terms.join(", "); 
       return false; 
      } 
     }); 
}); 
function split(val) { 
    return val.split(/,\s*/); 
} 
function extractLast(term) { 
    return split(term).pop(); 
} 

控制器代碼：

當我試圖靜態的JavaScript陣列自動完成多個值工作完美

public JsonResult AutoCompleteUsers(string term) 
    { 
     var result = (from r in db.UserItems 
         where r.Name.ToLower().Contains(term.ToLower()) 
         select new { r.Name, r.Email, r.UserId }).Distinct(); 
     return Json(result, JsonRequestBehavior.AllowGet); 
    } 

！

我認爲錯誤可能是在這一塊，但我不知道該解決方案

customData = $.map(data, function (item) { 
          userId = item.UserId; 
          return { label: item.Name + "(" + item.Email + ")", value: item.Name } 
         });

感謝每一個機構誰試圖解決我的問題，誰心不是，我解決我的問題，這裏是爲大家解決方案：
我的視圖代碼：

@Html.TextBox("SentUsers", "", new { @class = "text-box"}) 
@Html.Hidden("UsersId") 

我的javascript代碼：

<script type="text/javascript"> 
$(function() { 
    $("#SentUsers") 
     .bind("keydown", function (event) { 
      if (event.keyCode === $.ui.keyCode.TAB && 
      $(this).data("ui-autocomplete").menu.active) { 
       event.preventDefault(); 
      } 
     }) 
     .autocomplete({ 
      minLength: 2, 
      source: function(request, response) { 
       $.getJSON("/Ajax/AutoCompleteUsers", { 
        term: extractLast(request.term) 
       }, response); 
      }, 
      search: function() { 
       // custom minLength 
       var term = extractLast(this.value); 
       if (term.length < 2) { 
        return false; 
       } 
      }, 
      focus: function() { 
       // prevent value inserted on focus 
       return false; 
      }, 
      select: function (event, ui) { 
       var usersIdVal = $("#UsersId").val(); 
       usersIdVal += ", " + ui.item.userId; 
       $("#UsersId").val(usersIdVal) 

       var terms = split(this.value); 
       // remove the current input 
       terms.pop(); 
       // add the selected item 
       terms.push(ui.item.value); 
       // add placeholder to get the comma-and-space at the end 
       terms.push(""); 
       this.value = terms.join(", "); 
       return false; 
      } 
     }); 
}); 
function split(val) { 
    return val.split(/,\s*/); 
} 
function extractLast(term) { 
    return split(term).pop(); 
} 

我控制器代碼：

public JsonResult AutoCompleteUsers(string term) 
    { 
     var result = (from r in db.UserItems 
         where r.Name.ToLower().Contains(term.ToLower()) 
         select new { label = r.Name + "(" + r.Email + ")", value = r.Name, userId = r.UserId }).Distinct(); 

     return Json(result, JsonRequestBehavior.AllowGet); 
    }
