I've the below code from a tutorial,i want the action but i just want to remove the alert,

here is the code:

<script type="text/javascript">
setTimeout('read()', 10000);

function read()
{
FB.api('/me/news.reads' + 
'?article=<?php echo $fbrdurl ?>&access_token=<?php echo $access_token ?>','post',
function(response) {
var msg = 'Error occured';
if (!response || response.error) {
if (response.error) {
msg += "\n\nType: "+response.error.type+"\n\nMessage: "+response.error.message;
}
alert(msg);
} 
else {
alert('Post was successful! Action ID: ' + response.id);
}
});
}
</script>

I've tried this:

<script type="text/javascript">
setTimeout('read()', 10000);

function read()
{
FB.api('/me/news.reads' + 
'?article=<?php echo $fbrdurl ?>&access_token=<?php echo $access_token ?>','post';
}
</script>

but not worked, thanks
