php - Javascript alternative of jQuery.ajax() - facing errors -


this js object 

var datas = {     name: "xyz",     age:21, }  var datas2 = json.stringify(datas);

the below ajax request passing datas correctly

 $(function(){         $.ajax({             url:'two.php',             type:'post',             datatype:'html',             data:{data:datas2}         });     });

response in developer tools:

array (     [data] => {"name":"xyz","age":21} )

now tried javascript ajax reuest

var xmlhttp; if (window.xmlhttprequest)   {// code ie7+, firefox, chrome, opera, safari   xmlhttp=new xmlhttprequest();   } else   {// code ie6, ie5   xmlhttp=new activexobject("microsoft.xmlhttp");   } xmlhttp.onreadystatechange=function()   {   if (xmlhttp.readystate==4 && xmlhttp.status==200)     {      }   } xmlhttp.open("post","two.php",true); xmlhttp.setrequestheader("content-type","application/x-www-form-urlencoded"); // xmlhttp.setrequestheader("content-type","application/json"); xmlhttp.send(datas2);

response in developer tools:

array (     [{"name":"xyz","age":21}] =>  )

where going wrong?

you sending 2 different values. jquery convert object {data: datas2} string

data={"name":"xyz","age":21}

whereas xmlhttp.send(datas2) send string

{"name":"xyz","age":21}

that's big difference! in second case {"name":"xyz","age":21} treated parameter name instead of value see developer tools.

if want send same payload, have do

xmlhttp.send('data=' + datas2')
