JS 滚动文字效果

     function func() {
            var text = document.getElementById("lilei").innerText;
            var a = text.charAt(0);
            var b = text.substring(1, text.length);
            var new_text = b + a;
            document.getElementById("lilei").innerText = new_text;
        }
        setInterval(func,500);

 

jQuery版：

    setInterval(function () {
        var text=$("p").text();
        var a=text.charAt(0);
        var b=text.substring(1,text.length);
        var new_text=b+a;
        $("p").text(new_text);
    },200);
