Uncaught ReferenceError: ошибка не определена в обратном вызове Ajax

Question

В моем приложении я получаю список событий из списка календарей Sharepoint. Эта часть работает отлично. Однако после получения коллекции результатов для каждого элемента мне нужно получить отображаемый Url формы, который является еще одним вызовом REST с идентификатором ListItem.

Однако я получаю ошибку ниже, но я до сих пор не знаю, что эта проблема может быть

Uncaught ReferenceError: error is not defined App.js:87(anonymous function) App.js:87$.ajax.error App.js:40c jquery-1.9.1.min.js:22p.fireWith jquery-1.9.1.min.js:22k jquery-1.9.1.min.js:24send.r 

я на основе моего кода на этот ответ: https://sharepoint.stackexchange.com/questions/119236/how-to-get-the-display-form-url-using-rest

Мой адаптированный код выглядит так:

var SPHostUrl; 
var SPAppWebUrl; 
var ready = false; 

// this function is executed when the page has finished loading. It performs two tasks: 
// 1. It extracts the parameters from the url 
// 2. It loads the request executor script from the host web 
$(document).ready(function() { 
    var params = document.URL.split("?")[1].split("&"); 
    for (var i = 0; i < params.length; i = i + 1) { 
     var param = params[i].split("="); 
     switch (param[0]) { 
      case "SPAppWebUrl": 
       SPAppWebUrl = decodeURIComponent(param[1]); 
       break; 
      case "SPHostUrl": 
       SPHostUrl = decodeURIComponent(param[1]); 
       break; 
     } 
    } 

    // load the executor script, once completed set the ready variable to true so that 
    // we can easily identify if the script has been loaded 
    $.getScript(SPHostUrl + "/_Layouts/15/SP.RequestExecutor.js", function (data) { 
     ready = true; 
     getItems(); 
    }); 
}); 

function getListItemFormUrl(webUrl, listName, listItemId, formTypeId, complete, failure) { 
    $.ajax({ 
     url: webUrl + "/_api/web/lists/GetByTitle('" + listName + "')/Forms?$select=ServerRelativeUrl&$filter=FormType eq " + formTypeId, 
     method: "GET", 
     headers: { "Accept": "application/json; odata=verbose" }, 
     success: function (data) { 
      var url = data.d.results[0].ServerRelativeUrl + '?ID=' + listItemId 
      complete(url); 
     }, 
     error: function (data) { 
      failure(data); 
     } 
    }); 
} 



// this function retrieves the items within a list which is contained within the parent web 
function getItems() { 

    // only execute this function if the script has been loaded 
    if (ready) { 

     // the name of the list to interact with 
     var listName = "Events"; 

     // the url to use for the REST call. 
     var url = SPAppWebUrl + "/_api/SP.AppContextSite(@target)" + 

      // this is the location of the item in the parent web. This is the line 
      // you would need to change to add filters, query the site etc 
      // "/web/lists/getbytitle('" + listName + "')/items?" + 
      "/web/lists/getbytitle('" + listName + "')/items?$select=Title,Category,EventDate,Description,EncodedAbsUrl,ID" + 
      "&@target='" + SPHostUrl + "'"; 

     // create new executor passing it the url created previously 
     var executor = new SP.RequestExecutor(SPAppWebUrl); 

     // execute the request, this is similar although not the same as a standard AJAX request 
     executor.executeAsync(
      { 
       url: url, 
       method: "GET", 
       headers: { "Accept": "application/json; odata=verbose" }, 
       success: function (data) { 

        // parse the results into an object that you can use within javascript 
        var results = JSON.parse(data.body); 
        var events = []; 
        $.each(results.d.results, function (i, obj) { 

         //Usage 
         getListItemFormUrl(SPAppWebUrl, 'Calendar', obj.ID, 4, 
          function (url) { 
           console.log('Display from url for list item: ' + url); 
          }, 
          function (sender, args) { 
           console.log(JSON.stringify(error)); 
          }) 

         //use obj.id and obj.name here, for example: 
         var event = { 
          date: Date.parse(obj.EventDate).toString(), 
          type: obj.Category, 
          title: obj.Title, 
          description: obj.Description, 
          url: obj.EncodedAbsUrl + 'DispForm.aspx?ID=' + obj.ID 
         } 
         events.push(event); 
        }); 
        var myJsonString = JSON.stringify(events); 

        $("#eventCalendarInline").eventCalendar({ 
         jsonData: events, 
         openEventInNewWindow: true, 
         showDescription: true, 
         txt_GoToEventUrl: "Go to event" 
        }); 

        Communica.Part.init(); 

       }, 
       error: function (data) { 

        // an error occured, the details can be found in the data object. 
        alert("Ooops an error occured"); 
       } 
      }); 
    } 
}

Под //Usage:

function (sender, args) { 
    console.log(JSON.stringify(error)); 
}) 

error, кажется, не быть определен
