function scroll(obj) {
var tmp = (obj.scrollLeft)++;

虽然已经是1ms了但如果还想快怎么办？急急急急 大虾啊 
 

Answer 1

如果是用setInterval应该没辙了吧，它的最小间隔就是1ms

Answer 3

不用setInterval的话 能加速就行 怎么办 谢谢了

Answer 4

var tmp = (obj.scrollLeft)++;=》var tmp = (obj.scrollLeft)+20;没必要1px 1px 的滚动

Answer 5

同意楼上说法
var tmp = (obj.scrollLeft)++;=》var tmp = (obj.scrollLeft)+这个值改大点;

Answer 6

function scroll(obj) {
var tmp = (obj.scrollLeft)++;
if (obj.scrollLeft==tmp) obj.innerHTML += obj.innerHTML;
if (obj.scrollLeft>=obj.firstChild.offsetWidth) obj.scrollLeft=0;
}改成:function scroll(obj) {
 var tmp = (obj.scrollLeft)++;
 if (obj.scrollLeft==tmp){
   obj.innerHTML += obj.innerHTML;
 }else{
   obj.scrollLeft = parseInt(obj.scrollLeft) + 10;
 } if (obj.scrollLeft>=obj.firstChild.offsetWidth) obj.scrollLeft=0;
}

w3c 规定 定时器 台式机minvalue 为2s 笔记本为5s
