[英]c# - Problems during AJAX call with Jquery
Good evening, I'm trying to do a AJAX call in a C# page and I'm dealing with some problems. 晚上好,我正在尝试在C#页面中进行AJAX调用,并且正在处理一些问题。
My jQuery code is: 我的jQuery代码是:
$(document).ready(function () {
$.ajax({
type: "POST",
url: "conteudo.aspx/GetNewPost",
data: { ids: "<%=Request.QueryString["idconteudo"]%>" },
contentType: 'application/json; charset=utf-8',
dataType: 'json',
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
},
success: function (data) {
alert("ok");
}
});
});
And my code-behind is: 我的后台代码是:
[WebMethod]
public static string GetNewPost(string ids)
{
// some code
return ids;
}
Does someone know what is going on? 有人知道发生了什么吗? PS: The error is
Internal Server Error
. PS:错误是
Internal Server Error
。
try: 尝试:
var idconteudo = "<%=Request.QueryString["idconteudo"]%>"; var idconteudo =“ <%= Request.QueryString [” idconteudo“]%>”;
... ...
... ...
url: "conteudo.aspx/GetNewPost", 网址:“ conteudo.aspx / GetNewPost”,
data: "{ids: \\"" + idconteudo + "\\"" }", 数据:“ {ids:\\”“ + idconteudo +” \\“”}“,
contentType: 'application/json; contentType:'application / json; charset=utf-8',
charset = utf-8',
... ...
... ...
Please use code as below 请使用以下代码
Because you are using text data type from query string, you can make datatype as text
因为您正在使用查询字符串中的文本数据类型,所以可以将数据类型设置为
text
$(document)
.ready(function () {
var q = "<%=Request.QueryString["idconteudo"]%>";
alert(q);// just to check the value
// assuming that you had passed query string value
$.ajax({
type: "POST",
url: "conteudo.aspx/GetNewPost",
data: { "ids": q },
//contentType: 'application/json; charset=utf-8',
dataType: 'text',// data type should be text
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert("Request: " +
XMLHttpRequest.toString() +
"\n\nStatus: " +
textStatus +
"\n\nError: " +
errorThrown);
},
success: function(data) {
alert("ok");
}
});
});
Edit 1 : If the Web Method is on ASPX page, you shall use below code, so that you get result in Json format 编辑1 :如果Web方法位于ASPX页面上,则应使用以下代码,以便以Json格式获取结果
$(document)
.ready(function () {
var q = "<%=Request.QueryString["idconteudo"]%>";
//alert(q);
// just to check the value
// assuming that you had passed query string value
$.ajax({
type: "POST",
url: "conteudo.aspx/GetNewPost",
data: '{ids: "' + q + '" }',
contentType: 'application/json; charset=utf-8',
dataType: 'json',
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Request: " +
XMLHttpRequest.toString() +
"\n\nStatus: " +
textStatus +
"\n\nError: " +
errorThrown);
},
success: function (result) {
alert("ok" + result.d);
}
});
});
From what you have given us with your post, I see two things that are incorrect and one other thing that may have just not been posted in your question, but it is in fact in your real source. 从您提供给我们的帖子中,我发现有两件事是不正确的,另一件事可能是您的问题中尚未发布的,但实际上这是您的真实资料。
1) Your data
is written wrong. 1)您的
data
写错了。 It should be: 它应该是:
$(document).ready(function () {
var test = "<%=Request.QueryString["idconteudo"]%>";
$.ajax({
type: "POST",
url: "conteudo.aspx/GetNewPost",
data: { 'ids' : test }, // the ids needs to have quotes to be correct syntax
dataType: 'text',
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
},
success: function (data) {
alert("ok");
}
});
});
2) You say it's a POST
but your method isn't decorated with the [HttpPost]
Annotation. 2)您说这是
POST
但您的方法未使用[HttpPost]
注释修饰。
3) Your dataType
is set to 'json'
but your method is returning a string
.. so 'json'
should be changed to 'text'
. 3)您的
dataType
设置为'json'
但是您的方法返回一个string
..所以'json'
应该更改为'text'
。
Hope this helps! 希望这可以帮助!
