How do I call a server side VB.net function from jquery in an asp.net form?
提问by Jake Hunter
I am trying to call a method in my server-side vb code from jquery.
我正在尝试从 jquery 调用我的服务器端 vb 代码中的方法。
import System.Web.Services
...
'my VB.net Code
<WebMethod()> _
Public Shared Function SubmitReport_Click()
'this is where my code will go
Return Nothing
End Function
In my javascript code the alert is being called but the SubmitReport_Click is not being called.
在我的 javascript 代码中，正在调用警报但未调用 SubmitReport_Click。
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"></asp:ScriptManager>
<script type="text/javascript">
$("#<%= FileInput.ClientID%>").on('filebatchselected', function (event) {
alert("file input");
pagemethods.SubmitReport_Click();
})
</script>

I'd make a function that fires on the click event and calls over to your web method using AJAX, and use JSON to pass any relevant data.
我会创建一个函数来触发点击事件并使用 AJAX 调用您的 Web 方法，并使用 JSON 传递任何相关数据。
$(".clickMe").click(doWebMethod);
function doWebMethod () {
var data = { 'name': 'jessikwa' , 'location': 'ny' }
var params = "{'dataPackage': '" + JSON.stringify(data) + "'}";
$.ajax({
type: "POST",
url: webMethodUrl,
async: true,
data: params,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
alert(msg.d);
},
error: function () {
alert("fail");
}
});
}
//VB HERE
<WebMethod()> _
Public Shared Function SubmitReport_Click(ByVal dataPackage as String) as String
Dim rtnStr As String = "OK"
//deserialize data package here
Return rtnStr
End Function

You can use an Ajaxrequest. I just typed this up, so you may need to Google the syntax in case I messed it up.
您可以使用Ajax请求。我刚刚输入了这个，所以你可能需要谷歌一下语法，以防我把它搞砸了。
$.ajax({
type: "GET",
url: "FileName.aspx/SubmitReport_Click",
success: function(){
alert('It Worked!');
},
failure: function() {
alert('It Failed!');
}
});
