Can i send data through querystring and body using HTTP POST method?

<br />
function GetData()<br />
{<br />
	//make the object here<br />
	// to communicate/send data to the server, you need to add data as a <br />
	//querystring. for this, make a variable called url. Let it refer to the same <br />
	//page. Assuming, you have this page called AJAX.aspx,<br />
		<br />
	var url='AJAX.aspx';<br />
<br />
	//if you wanna pass the contents of a textbox named 'txtOrderNumber'<br />
	//get the textbox<br />
	<br />
	var reqdBox = GetObject('txtOrderNumber','input');<br />
	<br />
	//append the value to the url <br />
	<br />
	url = url + '?Data=' + reqdBox.value;<br />
<br />
	//the step above is important as this is the only way data is sent to server.<br />
	//then, open the oxmlhttp object and pass the reqd. parameters.<br />
<br />
	oxmlhttp.open("GET",url,true);<br />
	<br />
	//(method, reqd url, async?)<br />
<br />
	//as we are saying GET in the method, we have to pass null as a parameter <br />
	// for the send() method. ie<br />
<br />
	oxmlhttp.send(null);<br />
	<br />
	//this will send the data to the server asynchronously.<br />
