Code:

<?php echo $library_src;?>
<?php echo $script_head;?>

Thank you patwork!

I finally find the reason. My web page have many "<div>" code.So the jquery open layer(effect div) don't show normally. even I set these div's z-index to -1 it don't work ：（
I have to change my web page's div to table if I want to use jquery effect.
