在vue项目中引用外部插件VueImgSlider.vue:
import VueImgSlider from '../components/VueImgSlider.vue'
export default {
name: 'website-about',
components: {
'vue-img-slider': VueImgSlider
},
data () {
return {
demoData:[
{
img: '../src/assets/img/wmda.png',
title: 'wmda'
},
{
img: '../src/assets/img/team.png',
title: '团队'
},
{
img: '../src/assets/img/tb1.jpg',
title: 'tb1'
},
{
img: '../src/assets/img/tb2.jpg',
title: 'tb2'
}
]
}
}
}
使用方法:
<vue-img-slider
style="width: 400px;height: 400px;"
:type="'left'" //跑马灯方向。left:水平方向;top:垂直方向
margin="'20px'" //每张图片的间隔
:speed="20" //图片滑动的速度
:imgData="demoData" //图片和文字数据
:txtPos="['40%','10%']" //图片文字位置
>
</vue-img-slider>
