Calling webmethod ina aspx.cs file using jquery ajax
提问by Luke Villanueva
I have a default.aspx.cs which contains my webmethod to call and I have my js file that containg my jquery ajax. I can't get to call the webmethod.
我有一个 default.aspx.cs，其中包含要调用的 webmethod，并且我的 js 文件包含我的 jquery ajax。我无法调用 webmethod。
Here is my default.aspx.cs:
这是我的 default.aspx.cs：
protected void Page_Load(object sender, EventArgs e)
{
string[] MyArray = new string[1];
MyArray[0] = "My Value";
Grid1D.DataSource = MyArray;
Grid1D.DataBind();
}
[WebMethod]
public Details[] getDetails(string columnname, string inputVal)
{
List<Details> list = new List<Details>();
DbAccess dbacc = new DbAccess();
DataTable dt = dbacc.getReportDetails(columnname, inputVal);
foreach (DataRow row in dt.Rows)
{
Details _Details = new Details();
_Details.memid = row["memid"].ToString();
_Details.usrname = row["usrname"].ToString();
_Details.fullname = row["fullname"].ToString();
_Details.fname = row["fname"].ToString();
_Details.mname = row["mname"].ToString();
_Details.lname = row["lname"].ToString();
_Details.bdate = row["bdate"].ToString();
_Details.address = row["address"].ToString();
_Details.sponsorid = row["sponsor_id"].ToString();
_Details.parentid = row["parent_id"].ToString();
_Details.placement = row["placement"].ToString();
_Details.datejoined = row["date_joined"].ToString();
list.Add(_Details);
}
Grid1D.DataSource = list.ToArray();
Grid1D.DataBind();
return list.ToArray();
}
And here is my js file:
这是我的 js 文件：
function retrieveReportData() {
var columnName = $("#ddlFilters").val();
var input = $("#tags").val();
if (columnName != "Select") {
var Data = JSON.stringify({ columnname: columnName, inputVal: input });
alert(Data);
$.ajax({
url: "Default.aspx/getDetails",
data: Data,
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
success: function (mydata) {
alert(mydata.d);
}
});
}
else
alert("Please choose search filter");
}
You may notice that I'm alerting my data to ensure that I have the right values to send to my webmethod. But just like I said, it fails to call my webmethod and don't proceed to my success function within my ajax. Help! Thanks! :)
您可能会注意到我正在提醒我的数据以确保我有正确的值发送到我的 webmethod。但就像我说的那样，它无法调用我的 webmethod，也不会在我的 ajax 中执行我的成功功能。帮助！谢谢！:)

You webmethod needs to be static.
你的 webmethod 需要是static.
[WebMethod]
public static Details[] getDetails(string columnname, string inputVal)

Try to set typeto "Get" and send the parameters in the URL instead of Data
尝试设置type为“获取”并在 URL 中发送参数而不是数据
url: "Default.aspx/getDetails/?colunmname="+colname+"&inputVal="+inputValue,
type: "GET"
