HTML文字无缝滚动JS代码是一种非常实用的网页元素,可以使你的网站更加动感,增强用户的体验感。下面,我们就来介绍一下HTML文字无缝滚动JS代码的实现方法。
function TextScroll(type, speed, height) { var that = this; this.type = type; this.speed = speed; this.height = height; this.container = document.querySelector(".scroll-container"); this.content = this.container.querySelector(".scroll-content"); this.btnUp = this.container.querySelector(".scroll-up"); this.btnDown = this.container.querySelector(".scroll-down"); this.scrollHeight = this.content.scrollHeight; this.init = function() { if(this.type==1){that.container.style.overflow = "scroll";that.container.style.height = "400px";} if(this.type==2){that.container.style.height = that.height+"px";that.content.style.marginTop=-that.height+"px";} that.content.innerHTML += that.content.innerHTML;} this.play = function() { var scroll = setInterval(function(){ if(that.type==1){ var scrollTop = that.container.scrollTop; that.container.scrollTop = scrollTop+1; if(scrollTop == that.scrollHeight) { that.container.scrollTop = 0; } } if(that.type==2){ var marginTop = parseInt(that.content.style.marginTop); if(marginTop>=-that.scrollHeight){ that.content.style.marginTop=(marginTop-1)+"px"; }else{ that.content.style.marginTop = -that.height + "px"; that.content.style.marginTop=(marginTop+1)+"px"; } } },that.speed); } this.stop = function() { var scroll = setTimeout(function(){ clearInterval(scroll); },1); } }
以上是一个HTML文字无缝滚动JS代码的示例,代码中包含了样式、HTML和js三部分。使用该代码实现无缝滚动的效果,可以根据自己的需要进行适当调整,比如速度、高度等等。总之,HTML文字无缝滚动JS代码是网页设计中常用的特效之一,掌握该技能,对于提升网页的美观度和功能性都有很大帮助。
