Table实现tr数据滚动

先定义对象fontUpRoll及属性

/*文字上下滚动*/
function fontUpRoll(dom,tableH){
    this.dom = $(dom);
    //this.h = this.dom.height();
 this.h = tableH;
    this.timer = null;
 this.init();
}
fontUpRoll.prototype = {
    constructor: fontUpRoll,
    init: function(){
        this.dom.append(this.dom.html());
        this.play();
        this.hover();
    },
    play: function(){
        var that = this;
        this.timer = setInterval(function(){
            that.dom.css('margin-top', parseInt(that.dom.css('margin-top')) - 1 + 'px');
            if(parseInt(that.dom.css('margin-top')) == -that.h){
                that.dom.css('margin-top', 0);
            }
        }, 50)
    },
 hover: function(){
  var that = this;
  this.dom.hover(
   function(){
    clearInterval(that.timer);
         },
   function(){
             that.play();
         }
  );
 }
}

 

后使用该方法

var tableH;
tableH=$('.jzBox .table_02 table tr').length*24;
/*文字上下滚动*/
var fontUpRoll_01 = new fontUpRoll('.table_02 table',tableH);

 

 

 

html文件代码：
