ASP.NET的调用代码功能从Javascript

我做了一个webmethod，我试图从javascript调用，但它似乎并没有被解雇。我从一个用户控件的内部列表框中获取选定的索引值并将其传递给我的web方法以删除选定的用户。我看过无数的网站，并没有找到解决方案。我没有收到任何错误，其他的一切似乎都在起作用。我已经尝试从代码中的公共子代中调用这个函数，也没有运气。任何建议，非常感谢！ASP.NET的调用代码功能从Javascript

粘贴您的的WebMethod Deleteuser代码的链接。 – 2013-04-24 04:51:18

我认为你应该使用JSon来调用Web方法，下面是简单的例子

$.ajax({ 
type: "POST", 
contentType: "application/json; charset=utf-8", 
url: "yourpage.aspx/yourmethod", 
data: "{}", 
dataType: "json", 
success: function(data) { 
//Write functionality to display data 
}, 
error: function(result) { 
alert("Error"); 
} 
});

这里是可以帮助您Link
