[英]ASP.NET webmethod get ajax with parameters
I have a webmethod like this: 我有这样的网络方法:
[WebMethod]
[ScriptMethod(UseHttpGet = true)]
public static string test(string Name, int? Age)
{
return "returned value";
}
And the ajax call : 和ajax调用:
$.ajax({
type: "GET",
url: "form.aspx/test",
data: {'Name': "n1", 'Age': 30},
contentType: "application/json; charset=utf-8",
success: function (data) {
console.log(data);
}
});
Without parameters/data it works, but when I try to pass some parameters I get this error: 没有参数/数据,它可以工作,但是当我尝试传递一些参数时,出现此错误:
GET http://localhost:55410/test.aspx/test?Name=n1&Age=30
500 (Internal Server Error)
I think this's the detailed exception: 我认为这是详细的例外情况:
System.ArgumentException: Unknown web method form.
Parameter name: methodName
You need to pass an object instead of a string, and put quotes around n1
to make it a string: 您需要传递一个对象而不是字符串,并在
n1
周围加上引号以使其成为字符串:
$.ajax({
type: "GET",
url: "test.aspx/test",
data: {'Name': 'n1', 'Age': 30}, // remove quotes & add quotes to n1
contentType: "application/json; charset=utf-8",
success: function (data) {
console.log(data);
}
});
If you want to pass parameters with url you dont need to use data
property at all: Just pass them in the url itself like below: 如果要使用url传递参数,则根本不需要使用
data
属性:只需将它们传递给url本身,如下所示:
$.ajax({
type: "GET",
url: "form.aspx/test?name=" + yourStringVariabel + "&age=" + yourAgeVariabel,
contentType: "application/json; charset=utf-8",
success: function (data) {
console.log(data);
}
});
Try with a post and see if it works: 尝试发布,看看是否可行:
$.ajax({
type: "POST",
url: "form.aspx/test",
data: JSON.stringify({ name: 'N1', age : 1 }),
contentType: "application/json; charset=utf-8",
success: function (data) {
console.log(data);
}
});
