回复：在<?php ?>内，如何将变量值赋给JS变量？

php可以直接echo给js，js要传给php最好用cookie

<?php
echo "<script type='text/javascript'>";
echo 'var arr =[';
echo '{ id:2, pId:0, name:"新闻"},';
echo '{ id:16, pId:0, name:"折扣"},';
echo '{ id:17, pId:0, name:"创业"},';
echo '];';
　　echo "</script>";
?>
<script type="text/javascript">
　　alert(arr[0]['name']); //这里可读出php给js变量的结果
</script>
</head>
