Controller :
[HttpPost]
public ActionResult FileExist(string fileName)
{
bool result = true;
string path = Server.MapPath(TempPath) + fileName + ".xlsx"; //Path for the file
string[] Files = Directory.GetFiles(Server.MapPath(TempPath));
for (int i = 0; i < Files.Length; i++)
{
if (path == Files[i])
{
//The filename already exists
result = false;
}
}
return Json(new { returnvalue = result });
}
我的JS:
$(document).on('click', '#saveButton', function () {
var fileName = $('#fileName').val();
$.ajax({
type: 'POST',
url: '/Calculation/FileExist',
data: { 'fileName': fileName },
dataType: 'JSON',
success: function (result) {
if (!result.returnvalue) {
$('#errorMessage').text("The filename already exists. Please choose another one (The files are automatically deleted every second day)");
$('#downloadButton').css("visibility", "hidden");
}
}
});
});
当我在 VS 中调试它时,它工作正常。但是,当我发布并将其放在服务器上时,它就无法工作了。
我的错误是这样的:
为什么这在发布时不起作用?
最佳答案
考虑到 Calculation
是您的 Controller 类,尝试按以下方式给出 ajax 请求
$.ajax({
type: 'POST',
url: '@Url.Action("FileExist","Calculation")',,
data: { 'fileName': fileName },
dataType: 'JSON',
success: function (result) {
if (!result.returnvalue) {
$('#errorMessage').text("The filename already exists. Please choose another one (The files are automatically deleted every second day)");
$('#downloadButton').css("visibility", "hidden");
}
}
});
如果这个事件是写在一个单独的 js
文件中,那么这里是一个代码。
在您的 View 中创建一个 js 函数作为
function GetUrlToCheckIfFileExist(){
return '@Url.Action("FileExist","Calculation")';
}
在你的js
文件中使用下面的代码
var getUrlToCheckIfFileExist = window.GetUrlToCheckIfFileExist();
$.ajax({
type: 'POST',
url: getUrlToCheckIfFileExist,
data: { 'fileName': fileName },
dataType: 'JSON',
success: function (result) {
if (!result.returnvalue) {
$('#errorMessage').text("The filename already exists. Please choose another one (The files are automatically deleted every second day)");
$('#downloadButton').css("visibility", "hidden");
}
}
});
