jQuery实现文字横向滚动效果

Posted 2020-09-05 雅望天堂

html代码：

<div id="aaa" style="width:100px; position:relative; white-space:nowrap; overflow:hidden; height:20px;">  
<div id="noticeList" style="position:absolute; top:0; height:20px;">
<span>jQuery文字横向滚动</span>
</div>  
</div>

Jquery代码：

$.fn.textScroll=function(){  
        var p = $(this),  c = p.children(), speed=3000; //值越大速度越小
        var cw = c.width(),pw=p.width();  
        var t = (cw / 100) * speed;  
        var f = null, t1 = 0;  
        function ani(tm) {  
            counttime();  
            c.animate({ left: -cw }, tm, "linear", function () {  c.css({ left: pw });  clearInterval(f);  t1 = 0;  t=((cw+pw)/100)*speed;  ani(t); 
            });  
        }  
        function counttime() { 
            f = setInterval(function () {  
                t1 += 10;  }, 10);  
        } 
        p.on({  mouseenter: function () {  
            c.stop(false, false);  
            clearInterval(f); 
            console.log(t1);  
        },  mouseleave: function () { 
            ani(t - t1);  
            console.log(t1); 
        }  });  
        ani(t);  }

　　页面调用:

$(function(){
$("#aaa").textScroll();//aaa为最外层div的Id  也可写Class  如：$(".aaa") 此处aaa为class名
});
