PHP jQuery value problem

I have problem to send value from php to jQuery script.

PHP looks like that:

echo "<a id='klik' value='".$row['id']."' onclick='help()' href='http://www.something.xx/tag/".$row['link']."'>".$row['name']."</a><br>";

and script jQuery:

function help(){    
var j = jQuery.noConflict();

var zmienna = j('#klik').val();
alert(zmienna);
j.post('licznik.php',{id:zmienna}, function(data) {
    alert(data);
});

 }

licznik.php

    $p=$_POST;
    $id=$p['id'];
    echo $id;
    $wtf = "UPDATE tag_content SET wyswietlenia=wyswietlenia+1 WHE开发者_如何学JAVARE id='$id'";
    $result = mysql_query($wtf);

And as I tested, it has problem at the begining (alert(zmienna); doesn't work, shows nothing). How to fix it? Thx for help and if u want more informations (like more code etc.) let me know.

{id:zmienna} is not JSON, {'id':'zmienna'} is. Fix that.

The a tag can't have a value. What you can do is pass the id as a parameter:

echo '<a id="klik" onclick="help(\''.$row['id'].'\')">...</a>';

and in Javascript:

function help(zmienna) {
    alert(zmienna);
}

That's probably because the anchor tag has no value attribute (http://www.w3.org/TR/html4/struct/links.html). Try this instead:

var zmienna = j('#klik').attr('value');

I would also advice against using value. If I need additional data, I use a tag like data.
