前端頁面需先引入jquery

.box{
width : 18rem;

</body>
<script>
$(document.body).ready(function(){
$(".record_list").RollTitle({line:1,speed:800,timespan:1});
});
</script>
</html>
利用定時器實現中獎記錄逐行展示
recordRoll.js
/**
* Created by lin on 2017/3/12.
*/
(function($){
$.fn.extend({
RollTitle: function(opt){
if(!opt) var opt={};
var _this = this;
_this.timer = null;
_this.lineH = _this.find("p:first").height();
_this.line=opt.line?parseInt(opt.line,15):parseInt(_this.height()/_this.lineH,10);
_this.speed=opt.speed,
_this.timespan=opt.timespan;
if(_this.line==0) this.line=1;
_this.scrollUp=function(){
_this.animate({
marginTop:0
},_this.speed,function(){
for(i=1;i<=_this.line;i++){
_this.find("p:first").appendTo(_this);
}
_this.css({marginTop:0});
});
}
_this.hover(function(){
clearInterval(_this.timer);
},function(){
_this.timer=setInterval(function(){_this.scrollUp();},_this.timespan);
}).mouseout();
}
})
})(jQuery);
