Hi ,

I am using ajax jason in my application developed in .net 2.0.When i migrated to .net 4.0 the ajax function returning a jason object as [Object Object]

C#

$.ajax({
        type: "POST",
        async: false,
        timeout: 500,
        url: "../PageMethod.aspx/Sample",
        data: '{"Id":"'+Id+'"}',
        contentType: "application/json",
        dataType: "json",
        success: function(result)
        {
        alert(" Before Result "+result);
            document.getElementById(panelName).innerHTML = result;
            alert("Result After  "+result);
        }
    });

[WebMethod] public static string Sample(int Id)
 { string msg; StringBuilder sb = new StringBuilder(); sb.Append("<table cellspacing=\"3\" cellpadding=\"3px\">"); //Morecode sb.Append("</table>"); return sb.ToString(); 
}

Can any one tell me where I am doing mistake.
Thanks
Prashant
Note: When I hard code document.getElementById(panelName).innerHTML = 'HHHH';its working fine

[WebMethod]
public static string Sample(int Id)
{
string msg;
StringBuilder sb = new StringBuilder();
sb.Append("<table cellspacing=\"3\" cellpadding=\"3px\">");
//Morecode
sb.Append("</table>");

return sb.ToString();
}

Solution 3

what you are returning from the method is a html string not a json string which is expected by the ajax call (

JavaScript

contentType: "application/json",dataType: "json",

)

So you have two choices 1) change the sample method to return as a json string or 2) remove the

JavaScript

contentType

and

JavaScript

dataType

from your ajax method - jquery by default infers the correct type, in this case html.

hope this solves your problem.

Solution 2

In your code

C#

alert(" Before Result "+result); // use result.d
alert(" Before Result "+result.d)// use this line 
// same every where 
            document.getElementById(panelName).innerHTML = result.d;
            alert("Result After  "+result.d);

Hope this will help up
