用div+css+javascript实现首尾相连循环滚动效果(兼容firefox):
代码如下:
/*往左*/
var tmp = (obj.scrollLeft)++;
//当滚动条到达右边顶端时
if (obj.scrollLeft == tmp) {
obj.innerHTML += obj.innerHTML;
}
//当滚动条滚动了初始内容的宽度时滚动条回到最左端
if (obj.scrollLeft >= obj.firstChild.offsetWidth) {
obj.scrollLeft = 0;
}
/*往上*/
//var tmp = (obj.scrollTop)++;
//if (obj.scrollTop == tmp) {
// obj.innerHTML += obj.innerHTML;
//}
//if (obj.scrollTop >= obj.firstChild.offsetWidth) {
// obj.scrollTop = 0;
//}
}
var _timer = setInterval("scroll(document.getElementById('scrollobj'))", 20);
function _stop() {
if (_timer != null) {
clearInterval(_timer);
}
}
function _start() {
_timer = setInterval("_scroll(document.getElementById('scrollobj'))", 20);
}
