加載資源失敗：http：// localhost：59913/edit.aspx/LoadLanguages服務器響應狀態爲404（未找到）

我還在JavaScript的頁面加載方法中調用LoadLanguage，LoadLanguageSelect，LoadVideoLogLay和LoadImage JavaScript方法。以這種方式加載頁面時，這些方法中的操作將在加載頁面期間起作用。但是，在將javascript方法發佈到asp.net cs端時出現此錯誤。加載資源失敗：http：// localhost：59913/edit.aspx/LoadLanguages服務器響應狀態爲404（未找到）

我的JavaScript的頁面加載方法

 function PageLoad() { 
 
      LoadLanguages(1); 
 
      LoadLanguageList(); 
 
      LoadImageGallery(); 
 
      LoadVideoGallery(); 
 
     }

而且我在Javascript

function LoadLanguageList() { 
 
      $.ajax({ 
 
       url: "Edit.aspx/LoadLanguageSelect", 
 
       dataType: "json", 
 
       data: "{}", 
 
       contentType: "application/json; charset=utf-8", 
 
       method: "POST", 
 
       success: function (result) { 
 

 
        var xmlDoc = $.parseXML(result.d); 
 
        var xml = $(xmlDoc); 
 
        var languages = xml.find("Table"); 
 
        $('#select_AddLang').empty(); 
 
        if (languages.length > 1) 
 
         $('#select_AddLang').append($("<option></option>").attr("value", 0).text("Choose a language")); 
 
        else if (languages.length == 0)//All languages has already been added. 
 
         $('#select_AddLang').css("display", "none"); 
 

 
        languages.each(function() { 
 
         var language = $(this); 
 
         $('#select_AddLang').append($("<option></option>").attr("value", language.find("Ix").text()).text(language.find("Name").text())); 
 
        }); 
 
       }, 
 
       error: function (error) { 
 
        alert(error.d); 
 
       } 
 
      }); 
 
     }

方法 

function LoadImageGallery() { 
 
      $.ajax({ 
 
       url: "Edit.aspx/LoadImageGallery", 
 
       dataType: "json", 
 
       data: "{}", 
 
       contentType: "application/json; charset=utf-8", 
 
       method: "POST", 
 
       success: function (result) { 
 
        var xmlDoc = $.parseXML(result.d); 
 
        var xml = $(xmlDoc); 
 
        var pictures = xml.find("Table"); 
 
        $('#imagesList').empty(); 
 
        var x = 10; 
 
        pictures.each(function() {

我看到兩個問題

首先，我注意到，你的WebMethods不接受參數，但你specifting數據：「{}」在你的Ajax調用。當參數不必要時，請嘗試省略此行。如果頁面正在查找接受對象但未找到對象的方法，則可以返回404。看到這個答案：

How to call c# method with no parameters and access returned data?

您是否嘗試過使用小提琴手正在爲看你的AJAX請求？如果是這樣，請確保它實際上以POST請求發送。否則服務器將搜索一個GET方法，並且不會找到一個，因此返回一個404.

我總是使用$ .ajax（{type：「POST」「}）;而不是$ .ajax（{方法：「POST」「}）

我做了你說的。我在數據部分添加了」{}「。我在.NET 4.5框架中使用了這些代碼和方法。但是我嘗試從.net 4.5框架到.net 4.0框架然後我的項目得到這個錯誤。 – wotmn
