vue中使用定时器展示公告向上滚动
作者:互联网
<div class="groupall"> <div class="groupitem" @mouseenter="Stop()" @mouseleave="Up()" :style="{ top }" v-for="(item,index) in grouparr" :key="index"> <div class="groupitem1"> <div class="course_name"> <p class="course_text">{{item.name}}</p> <p class="course_price">¥{{item.price}}</p> </div> <div class="people_pic" @click="skillbutclick(item,1)"> <img :src="item.avatar" /> <span>加入队伍</span> </div> </div> </div> </div>
滚动方法
ScrollUp() { let arr=this.grouparrs this.intnum = setInterval((_) => { if (this.activeIndex < this.grouparr.length) { this.activeIndex += 1;//一次滚动几个 } else { this.activeIndex = 0; } }, 5000);//五秒一次,时间由定时器决定 },
Stop() { clearInterval(this.intnum);//清除定时器 }, Up() { this.ScrollUp();//继续滚动 },
每次向上滚动的高度
computed: { top() { return -this.activeIndex * 1.26 + "rem";//单位由你自己决定,也可以是
//return -this.activeIndex * 50 + "px"//以上两种写法都可以,看你的实际需求
}, },
