加载资源失败：http：// localhost：59913/edit.aspx/LoadLanguages服务器响应状态为404（未找到）
问题描述：
我还在JavaScript的页面加载方法中调用LoadLanguage，LoadLanguageSelect，LoadVideoLogLay和LoadImage JavaScript方法。以这种方式加载页面时，这些方法中的操作将在加载页面期间起作用。但是，在将javascript方法发布到asp.net cs端时出现此错误。加载资源失败：http：// localhost：59913/edit.aspx/LoadLanguages服务器响应状态为404（未找到）
我的JavaScript的页面加载方法
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);
}
});

而且我在浏览器中得到这个错误
答
我看到两个问题
首先，我注意到，你的WebMethods不接受参数，但你specifting数据：“{}”在你的Ajax调用。当参数不必要时，请尝试省略此行。如果页面正在查找接受对象但未找到对象的方法，则可以返回404。看到这个答案：
How to call c# method with no parameters and access returned data?
您是否尝试过使用小提琴手正在为看你的AJAX请求？如果是这样，请确保它实际上以POST请求发送。否则服务器将搜索一个GET方法，并且不会找到一个，因此返回一个404.
我总是使用$ .ajax（{type：“POST”“}）;而不是$ .ajax（{方法：“POST”“}）
我做了你说的。我在数据部分添加了”{}“。我在.NET 4.5框架中使用了这些代码和方法。但是我尝试从.net 4.5框架到.net 4.0框架然后我的项目得到这个错误。 – wotmn
