obj.match(regexp)                    全局搜索,如果正则中有g表示找到全部,否则只找到第一个。
obj.replace(regexp, replacement)     替换,正则中有g则替换所有,否则只替换第一个匹配项,
                                     $数字:匹配的第n个组内容;
                                     $&:当前匹配的内容;

            var tag = document.getElementById('i1');
            var content = tag.innerText;
            var f = content.charAt(0);
            var l = content.substring(1,content.length);
            var new_content = l + f;
            tag.innerText = new_content;
        }
        setInterval("func()", 500);
    </script>
