妳開個定時器，壹秒換壹個img的src不就行了？
隨便寫了個：
<div?id="app"><div?class="pic">
<img?:src="now"?/>
</div>
</div>
<script>
new?Vue({
el:"#app",
data:{
pic:["./images/1.jpg","./images/2.jpg","./images/3.jpg","./images/4.jpg","./images/5.jpg"],
i:"0",
now:"./images/1.jpg",
},
mounted:function(){
?this.now=this.pic[0];
?var?_this=this;
setInterval(function(){ _this.i++; _this.now=_this.pic[_this.i];if(_this.i>=_this.pic.length-1){
_this.i=0;
}
},1000)},
methods:{
}
})
</script>
