onclick passing more than 1 arguments in Ajax Java function

I have a radio button as an input and while onclick the Ajax java script function "processvalue" will be called by passing value of the radio button ('1' or '0') as well as a php variable...(say '<?php echo $event['eventid']; ?>').

How can I go about passing more than 1 arguments in the function and also then pass the values to the PHP file that will be called via the ajax function?

Example:

PHP/HTML:

<?php echo "YES"; ?>: <input type="radio" name="vote" value="1" onclick="getVote(this.value,'<?php echo $event['eventid']; ?>')" /> <?php echo $lang['NO']; ?>: <input type="radio" name="vote" value="0" onclick="getVote(this.value),'<?php echo $event['eventid']; ?>'"/>



Ajax:


function processvalue(vote,id)
{
if (str.length==0)
{
document.getElementById("Answer").innerHTML="";
return;
}

var xmlHttp;
try {
xmlHttp=new XMLHttpRequest();
}
catch (e) {
try {
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e) {
try {
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e) {
alert("Your browser does not support AJAX!");
return false;
}
}
}
xmlHttp.onreadystatechange=function() {
if(xmlHttp.readyState==4) {
document.getElementById("Answer").innerHTML=xmlHttp.responseText;
}
}
var url="show.php";
url=url+"?q="+vote;
url=url+"&t="+id;
xmlHttp.open("GET",url,true);
xmlHttp.send(null);
}


PHPshow.php)

<?php
$xvote = $_REQUEST['vote'];
$xevent=$_GET["id"];

echo $xvote;
echo $xevent;
?>

 

Is there no one could give a direction ?...

 

in your code, you call show.php and pass 2 variables to it:
the variable names are q and t so your show.php page should look like this:

$xvote = $_REQUEST['q'];
$xevent=$_GET["t"];

echo $xvote;
echo $xevent;

ok?
