请问smafty的问题

Question

{literal} 
<script language="javascript"> 
            function check() 
            {             alert({$aa});          
            } 
</script> 
{/literal} 
解释下literal 是什么意思.这个literal下的所有模板都被忽略掉,所以你这个程序是不对的
应该这样主要是大括号冲突才用{literal}的.
{literal} 
<script language="javascript"> 
            function check() 
            { 
{/literal}
            alert({$aa});  
{literal}         
            } 
</script> 
{/literal}

Answer 1

<script language="javascript"> 
var aa = {$aa};
            function check() 
            {             alert({aa});          
            } 
</script> 
{/literal}

Answer 2

前面错了
<script language="javascript"> 
var aa = {$aa}; 
            function check() 
            {             alert(aa);          
            } 
</script> 
{/literal}

Answer 3

<script language="javascript"> 
var aa = '{$aa}'; //加个引号就可以了
            function check() 
            {             alert(aa);          
            } 
</script> 
{/literal}
