javascript – JSON and ASP.NET WebMethod not firing server side method-Exceptionshub

Posted by: admin February 24, 2020 Leave a comment

Questions:

I’m trying to pass parameters to my code behind with WebMethod.

I’m reaching the success end of ajax but the method in my aspx.cs code behind doesn’t get called and I have error.

Operation failed! Details :'[object Object]

I’m using a masterpage if it makes a difference.

How to do resolve this ?

Please, can you help me ?

Javascript:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript" src="http://cdn.jsdelivr.net/json2/0.1/json2.js"></script>
<script type="text/javascript">
    $(function () {
        $("[id*=imgfasi]").bind("click", function () {
            var fasi = {};
            fasi.Txseltlc = $("[id*=txseltlc]").val();
            fasi.Txrescldisa = $("[id*=txrescldisa]").val();
            fasi.Ddlauttlc = $("[id*=ddlauttlc]").val();
            $.ajax({
                type: "POST",
                url: "Default.aspx/Savepnfasi",
                data: '{fasi: ' + JSON.stringify(fasi) + '}',
                contentType: "application/json; charset=utf-8",
                dataType: "json",

Try this :

var qString = "?" + window.location.href.split("?")[1];
var fasi = {};

...

url: "Default.aspx/Savepnfasi" + qString,
data: '{fasi: ' + JSON.stringify(fasi) + '}',
