以上代码跟c#写的Server.UrlEncode实现的效果是一样的，如果大家需要在客户端传入中文的字符，可以试试这个函数。
使用方法："http://www.fanchuanbook.com/search.aspx?q=" + EncodeURI(q,false)
<script>
var url="{PHPCMS_PATH}yczx/searchcy.php?ordertype=1&search=1&searchtype=content&catid=183&keywords="+EncodeURI("{$title}");
var encode=EncodeURI("{$title}");
document.write(‘<a href=\"‘ + url +‘\" target=\"_blank\" class=\"wg-x12\">‘);
document.write(‘点击可查看该场所所有演出排期</a>‘);
</script>
