$.post({
url: 'pdf.aspx',
//data: { ID: '1833' },
data: 'id=1833',
dataType: 'text',
type: 'post',
contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
success: function (data, textStatus, jQxhr) {
console.log("sssss " + data);
},
failure: function (msg) {
console.log("fffff " + msg);
},
error: function (jqXhr, textStatus, errorThrown) {
console.log(errorThrown);
}
});
我背后有代码:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load
Dim ID = Request.Form("id")
Response.Write(ID)
End Sub
结果我得不到ID变量。我尝试了所有可能的选项,但仍有问题。有任何想法吗?谢谢你的回答!

这是你的aspx:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="VisualBasicWebForm.WebForm1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="Scripts/jquery-1.12.0.min.js"></script>
<script type="text/javascript">
$(function () {
$("#theBtn").click(function () {
$.post({
url: 'WebForm1.aspx/GetData',
type: 'POST',
//using get all textbox selector-you can use a different selector
data: '{ID: "' + $(":text").attr("ID") + '" }',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data, textStatus, jQxhr) {
//don't forget the .d
alert("sssss " + data.d);
},
error: function (jqXhr, textStatus, errorThrown) {
console.log(errorThrown);
}
});
})
})
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox runat="server" ID="passToServer" />
<input type="button" id="theBtn" value="Go" />
</div>
</form>
</body>
</html>
以下是您的代码:
Imports System.Web.Services
Public Class WebForm1
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
<WebMethod()>
Public Shared Function GetData(ByVal ID As String) As String
'Dim ID = Request.Form("id")
'Response.Write(ID)
'Instead of the above, you can put a breakpoint on the next line to see value of ID
'Also returning ID so it is display, in your case sent to console.log
Return ID
End Function
End Class
