[英]Unable to execute Ajax call to c# method
Im trying to call ac# method on select changed event of a dropdown list,The select change event triggers but the ajax does not work 我试图在下拉列表的选择更改事件上调用ac#方法,选择更改事件触发但ajax不起作用
<script type="text/javascript">
$(document).ready(function () {
$('body').delegate('#drpselect1', 'change', function () {
var groupname = $("#drpselect1 option:selected").text();
alert(groupname);
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "sample.aspx/getdata",
dataType: "json",
{"text":groupname},
success: function () {
alert("works");
// window.location.href = "ClubCreation.aspx";
},
Error: function () {
alert('error');
}
});
/* $.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "sample.aspx/getdata",
data:{"text":groupname}
dataType: "json",
success: function () {
alert('Successfully Saved');
//window.location.href = "ClubCreation.aspx";
},
Error: function () {
}
});*/
});
});
</script>
c# method C#方法
[WebMethod]
public static void getdata(String text)
{
//do stuff
}
You have to decorate getdata method with [WebMethod]
attribute. 您必须使用
[WebMethod]
属性装饰getdata方法。 In your c# code [WebMethod]
is missing. 在您的C#代码中
[WebMethod]
丢失。
try this 尝试这个
check this line 检查这行
data:'{"text":"'+groupname+'"}',//put "data:"
now, 现在,
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "sample.aspx/getdata",
dataType: "json",
data:'{"text":"'+groupname+'"}',//put "data:"
success: function () {
alert("works");
// window.location.href = "ClubCreation.aspx";
},
Error: function () {
alert('error');
}
});
Probabky you missing attributes: 可能会丢失属性:
[System.Web.Services.WebMethod()]
public static void getdata(String text)
