Sign up to join this communityWell you can create an Application page with WebMethods
defined and than use simple jQuery Ajax to call the methods..
Please have a look at
Call WebMethod from JS in Visual web Part
$.ajax({ type: "POST", url: siteUrl + "/_layouts/SolutionName/WebMethods.aspx/Recount", data: "{'data':'" + data + "'}", contentType: "application/json; charset=utf-8", dataType: "json", async: true, success: function (data) { response(data["d"]); }, error: function (result) { //alert("Error"); } });
