javascript错误

[iwillfling]

在html中body中有以下代码：
49. <script type="text/javascript">
50. try{ace.settings.check('navbar','fixed')}catch(e){}
51. </script>

结果报错。
Smarty Error: Syntax Error in template "D:\wamp\www\havit/tpl\index.html" on line 50 "try{ace.settings.check('navbar','fixed')}catch(e){}" - Unexpected ".", expected one of: "}" , " "

该怎么解决？

看提示应该是使用语法错误吧 ace.settings.check()有定义吗
