}

but that just return a 500 error on my webpage any clue what im doing wrong? i would love some help here.

Answer 1

You can't run a PHP function from within the javascript, however its possible to inject the value you need within your javascript's .write method.

I cant see a happy ending for the provided example above:) maybe it's best to first clarify what is exactly the problem?

But if you have to make it functional here is a slightly cleaner approach

function doakrim()
{
    return "Test";
}

while (list($key, $val) = each($handlinger)) {
    echo '<tr onclick="document.write(\''. doakrim() .'\');"><td>'. $val .'</td><td>TEXT</td></tr>';
}

there is chance what you really need is an Ajax call to fetch the doakrim result back from a server, but its hard to say before knowing what exactly you want to achieve :)
