以上代碼跟c#寫的Server.UrlEncode實現的效果是一樣的，如果大家需要在用戶端傳入中文的字元，可以試試這個函數。

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(‘點擊可查看該場所所有演出排期</a>‘);
</script>
