</div>
<script type="text/javascript">
//获取节点
var btnList = document.getElementsByTagName("button");
var inner = document.getElementById("inner");
//可见宽度
var perWidth = inner.children[0].offsetWidth;
//添加事件
//循环调用事件包装成函数tab
function tab(){
inner.style.left = -perWidth * this.index + "px";
for(var j = 0; j < btnList.length; j++) {
btnList[j].className = "";
}
btnList[index].className = "active";
}
for(var i = 0; i < btnList.length; i++) {
btnList[i].index = i;
btnList[i].onclick = function() {
index=this.index;
tab();
}
}
var index =0;
function prom(){
index ++;
if(index > btnList.length-1){
index = 0;
}
tab();
}
var timer = setInterval(prom,2000);
inner.onmouseover = function() {
// alert("鼠标移入");
clearInterval(timer);
}
inner.onmouseout = function() {
// alert("鼠标移出");
timer = setInterval(prom,2000);
}
</script>
</body>
