jquery - Unable to send JSON data to server from javascript -


i need send json data server method.

this method works when pass simple 'test' string, not 1 follows:

function sendtoserver() {     $.ajax({         type: "post",         url: "default.aspx/saveclientgrid",         data: "{ griddata: 'test' }",         contenttype: "application/json; charset=utf-8",         datatype: "json"     }); }

doesn't work:

function sendtoserver() {     var data = json.stringify(datasource);     $.ajax({         type: "post",         url: "default.aspx/saveclientgrid",         data: "{ griddata: " + data + " }",         contenttype: "application/json; charset=utf-8",         datatype: "json"     }); }

figured it, 1 works:

function sendtoserver() {     var data = json.stringify(datasource);     $.ajax({         type: "post",         url: "default.aspx/saveclientgrid",         data: "{ griddata: '" + data + "' }",         contenttype: "application/json; charset=utf-8",         datatype: "json"     }); }

i had add single quotes around data - 

 data: "{ griddata: '" + data + "' }"
