Smarty如何将数组变量赋值给js
PHP文件中有类似代码：

$arr = array('A','B','C');
$smarty = new Smarty();
$smarty->assign('arr',$arr);
$smarty->display('test.html');


test.html大概是这样的

<script>
var arr = Smarty中赋值的数组变量;
</script>

===========================================================

怎么做比较简单，求解！
[解决办法]

$smarty->assign('js_arr',json_encode($arr));

<script>
var arr = {$js_arr};
</script>
