//////////////////////////////////some html////////////////////
<script type="text/javascript">
function nn(tuser, fuser, ta) {
alert(fuser + " send to " + tuser + " he say " +ta);
}
</script>
</body>
</html>
when you type someone's name in search box all user's profile with that name appear , and when you want to send to someone message you click on message and text area appear type a message and hit send , the problem is the text that you enter in text area doesn't pass to a function that you cant store it in db or do what ever you want with it as example i display the sender's name , profile's name and the message ,but the message doesn't pass, when i use var ta = document.getElementById("ta").value; for example there is two profile when i want to send message to the second profile's owner when i wrote the message and hit send it doesn't send anything because the var ta = document.getElementById("ta").value; pointer to the first profile's text area, so the only way to solve this problem is to pass that variable from php using something like that <div id="textmsg"><form method="post"><textarea id="taa"></textarea><button id="pmBtn" onClick="nn(\\''.$srch_name.'\\',\\''.$uname.'\\',\\'taa\\')">Send</button></form> i don't know why it can't pass the message.

Try this:
function test(a, b, c) {
alert(a + " live in " + b + " say " + document.getElementById(c).value);
}

I'd sooner use this.previousSibling.value:
<!doctype html>
<html>
<head>
<title>Untitled</title>
<script type="text/javascript">
function test(a, b, c) {
alert(a + ' live in ' + b + ' says ' + c + ".");
}
</script>
</head>
<body>
<?php
$a = 'Father Christmas';
$b = 'America';
echo sprintf('<textarea>Hello</textarea><button onclick="test(%s,%s,this.previousSibling.value)">LINK</button>',htmlentities(json_encode($a)),htmlentities(json_encode($b)));
?>
</body>
</html>
