obj.substring(from, to) 根据索引获取子序列
obj.slice(start, end) 切片
obj.toLowerCase() 大写
obj.toUpperCase() 小写
obj.split(delimiter, limit) 分割
obj.search(regexp) 从头开始匹配,返回匹配成功的第一个位置(g无效)
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;
$`:位于匹配子串左侧的文本;

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>
