This is supposedly very easy but for some reason it has taken me about 2 hours and countless searches and nothing is working
I am trying to call a WebMethod from ajax, and it works quite well. As soon as I try to change the c# function to accept parameters and send one from ajax everything fails
Code: c#:
[WebMethod]
public static string GetBGsForSelectedCrop(string cropName)
{
return "asdasd";
}
jquery:
$().ready(function () {
$("#Result").click(function () {
$.ajax({
type: "POST",
url: "Default.aspx/GetBGsForSelectedCrop",
data: "Wheat",
success: function (msg) {
$("#Result").text(msg.d);
alert(msg.d);
console.log(msg)
}
});
});
});
I have tried datatype: "json", contentType: "application/json; charset=utf-8", and tried without both and datatype: "string" and datatype: "text", GET, data: "{'ABCD'}, data:{"cropName: Wheat"}, and data: json.Stringify("Wheat").
I get undefined for msg.d and sometimes HTTP error 500 if I take it too far.
What am I missing? It is just a simple task and should've been done in seconds..
As the guys in the comments says, you need to change your code for:
$("#Result").click(function () {
$.ajax({
type: "POST",
url: "Default.aspx/GetBGsForSelectedCrop",
data: JSON.stringify({ cropName: "Wheat" }),
dataType:'text',
contentType: "application/json; charset=utf-8",
success: function (msg) {
$("#Result").text(msg.d);
alert(msg.d);
console.log(msg)
}
});
});
Your error is the data is no good encoded, and you are missing the datatype.
What is the stringfy It Convert any value to JSON.
