If you already have your own joomla component then it is fine otherwise create new one for yourself within minute.  Joomla Component Creator

Lets assume we have component “ajaxcall” and we are making ajaxcall from “com_ajaxcall\views\ajaxcall\tmpl\default.php” file.

We will make ajax call  to the format “ajaxcallformat” (i.e. view.ajaxcallformat.php)

javascript code in “com_ajaxcall\views\ajaxcall\tmpl\default.php”

<script type="text/javascript">

function AjaxCall(name)
{

var httpxml;
try
{
// Firefox, Opera 8.0+, Safari
httpxml=new XMLHttpRequest();
}
catch (e)
{
// Internet Explorer
try
{
httpxml=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
httpxml=new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e)
{
alert("Your browser does not support AJAX!");
return false;
}
}
}

function statecall()
{

if(httpxml.readyState==4)
{
var resp=httpxml.responseText;
alert(resp);

}
}

var url="index.php?option=com_ajaxcall&view=ajaxcall&format=ajaxcallformat";

var params="name="+name;

httpxml.onreadystatechange=statecall;
httpxml.open("POST",url,true);

//Send the proper header information along with the request
httpxml.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
httpxml.setRequestHeader("Content-length", params.length);
httpxml.setRequestHeader("Connection", "close");

httpxml.send(params);

}
</script>

AjaxCall in “com_ajaxcall\views\ajaxcall\default.php”

<label>Name:</label>
<input type="text" name="name" id="name">
<input type="button" value="Submit"
OnClick="AjaxCall(document.getElementById('name').value);">

view.ajaxcallformat.php will be in (i.e. com_ajaxcall\views\ajaxcall ) folder.
