Implement seamless scrolling in JavaScript and share the code to the sidebar instance _ javascript skills

This article provides seamless scrolling and sidebar effects through js Code, which are often encountered in projects. The following small series will organize the code and share it with the script home platform for your reference, the Code has been directly pasted to everyone, and the code solves a problem!

The following code describes the js seamless rolling instance code:

The Code is as follows:

 Untitled documentScript window. onload = function () {var oDiv = document. getElementById ('p1'); var oUl = oDiv. getElementsByTagName ('ul ') [0]; var aLi = oUl. getElementsByTagName ('lil'); var speed = 3oUl. innerHTML = oUl. innerHTML + oUl. innerHTML; oUl. style. width = aLi [0]. offsetWidth * aLi. length + 'px '; function move () {if (oUl. offsetLeft <-oUl. offsetWidth/2) {oUl. style. left = '0';} if (oUl. offsetLeft> 0) {oUl. style. left =-oUl. offsetWidth/2 + 'px ';} oUl. style. left = oUl. offsetLeft + speed + 'px ';}; var timer = setInterval (move, 30); oDiv. onmouseover = function () {clearInterval (timer) ;}; oDiv. onmouseout = function () {timer = setInterval (move, 30);} document. getElementsByTagName ('A') [0]. onclick = function () {speed =-3;}; document. getElementsByTagName ('A') [1]. onclick = function () {speed = 3 ;};}; scriptLeft to right

 
 

  
  

  
  

  
  

  
  

  
  

 
 

The js Code shared to the sidebar is as follows:

The Code is as follows:

 Untitled documentScript window. onload = function () {var oDiv = document. getElementById ('p1'); oDiv. onmouseover = function () {startMove (10, 0);} oDiv. onmouseout = function () {startMove (-10,-100) ;}} var timer = null; function startMove (speed, locall) {var oDiv = document. getElementById ('p1'); clearInterval (timer); timer = setInterval (function () {if (oDiv. offsetLeft = locall) {clearInterval (timer);} else {oDiv. style. left = oDiv. offsetLeft + speed + 'px ';}, 30);} script
